Living with a Heat Pump

Last year I wrote about the experience of Retrofitting a Heat Pump in my home in Dukes Ride.  As you have no doubt noticed, it has been cold this winter, and a lot of people have been asking how our heat pump handled the cold weather.  The short answer is “just fine”, but for those that want more detail here is a bit more technical information.

Firstly, a bit about how our heating is controlled

We run our house at about 20oC.  It is maintained at this temperature by setting the climate curve on our heat pump.  The heat pump controller measures the temperature outside and heats the water circulating in our radiators to exactly the right temperature to ensure that the house stays at the same temperature all day, every day.  When it’s -3oC outside, the water is heated to 45oC, when it’s 15oC outside the water is only heated to 25oC.  It took a bit of trial and error to get the climate curve right for us, but now the house stays at the right temperature all the time.  We could keep the house warmer, or cooler, by adjusting the climate curve up or down.

What happens when it gets cold outside?

When the external air is colder, the heat pump is less efficient.  It still heats everything to the required temperature, but it takes a bit more power to do it, and because it’s cold we need to heat the water to a higher temperature – a double whammy!  There is a very good correlation between the temperature outside and the power that our heat pump uses over a 24 hour period:

The eagle-eyed among you will spot that the day that the temperature dropped to -8oC, the energy usage is a little below the trend line.  That’s because (as set) our heat pump climate curve only went down to -3oC, and so at -8oC we were a little under-heated.  Had the low temperatures persisted, I could easily have adjusted that. 

How much did it cost?

If I assume an electricity price of 34.04p/kWh and a gas price of 10.33p/kWh, how did we do?

I have compared our monthly electricity usage in heating our house this year with our monthly gas usage over the last year that we had gas (2020-2021). 

To breakeven, we have to use around one-third of the electricity than we would have used gas.  Most of the time we do, and over the whole year we will be about £400 better off than had we been on gas.  However, as it gets colder the heat pump is less efficient, so it does cost more in the winter and less in the spring and autumn.  This has been a cold winter, and we have spent £60 more heating our house over the last three months than we would have spent on gas.  However, as soon as the weather warms up, the heat pump gets more efficient and we expect to more than recover this overspend over the next couple of months.

So Why Have a Heat Pump?

A saving of £400 a year doesn’t pay for the additional cost of installing a heat pump, so why do it?

For the future of our children!  Our heating and hot water now uses about one quarter of the energy that we previously used.  That’s a massive 2.5 tons CO2 that we are saving each and every year, and this figure is increasing as the electricity grid decarbonises.  In a world where we need to reduce our carbon footprint from around 10 tons CO2 per person per year to nothing as quickly as possible, that makes a difference.

Have Yourself a Sustainable Little Christmas

Christmas can generate plenty of extra household waste and Basingstoke and Deane Borough Council is urging residents to recycle more during the festive season.
To recycle more at home, choose drinks in plastic bottles rather that cartons and put them in your green bin after they are finished.  Any extra recycling that won’t fit in the recycling bin can be put in clear sacks next to it for collection. In dry weather residents can leave large, flattened cardboard boxes (max 1m x 1m) next to their green bin but make sure polystyrene and plastic packaging is removed first.
There are lots of other items that can be recycled during the festive season and throughout the year including paper, newspapers and magazines, food tins, drinks cans and aerosols.
If sending cards or wrapping presents, residents are advised to choose recyclable Christmas wrapping paper and cards. Wrapping paper often has glitter on it and is generally poor quality paper so cannot be recycled and needs to go into the grey waste bin but brown paper, with ribbon and cellotape removed, can be recycled. Choosing Christmas cards which do not contain glitter, ribbons or bows means they can be recycled too. If you are unsure about what can and can’t be recycled visit or call the council on 01256 844844.
As in previous years, garden waste customers will be able to put their real Christmas trees out for collection with their garden waste from Monday 9 January. Christmas trees over 6ft need to be cut in half and decorations must be removed. Real Christmas trees can also be recycled at one of 21 drop-off points across the borough between Monday 2 January and Sunday 29 January 2023. For more information visit
Glass recycling is very popular at Christmas, your glass box or glass bin should be placed next to your green recycling bin by 7am on your recycling collection day. All bottles and jars should be rinsed out and any corks or tops removed. Don’t overfill the glass box or bin as it will not be emptied and please do not put bottles or jars out for collection in any other container.
Residents can pick up a free green glass box from the council offices in London Road, Basingstoke if they have lots of bottles and jars to recycle this festive season. Visit Deanes reception between 8.30am and 4.30pm from Monday to Friday, alternatively call 01256 844844 to request delivery. A red 140 litre glass bin can also be purchased for £40 as an alternative to a box by calling 01256 844844. Visit  for more information.

Collection days will change over the Christmas break and the revised dates are shown below. Unless adverse weather affects bin rounds, collections should return to normal from Monday 2 January 2023. The crews will take extra rubbish sacks on the first collection after Christmas only and as usual they will pick up extra recycling too.

Normal collection date                                          Festive collection date
Monday 26 December                                            Tuesday 27 December
Tuesday 27 December                                            Wednesday 28 December
Wednesday 28 December                                      Thursday 29 December
Thursday 29 December                                           Friday 30 December
Friday 30 December                                                Saturday 31 December

Cabinet Member for Environment and Climate Action Cllr Hayley Eachus said: “Extra rubbish will be inevitable over the festive period but a lot of that can be recycled including glass bottles and jars, plastic bottles, cardboard boxes, aerosols, tins and cans. We can all make changes to contribute to a more sustainable start to 2023 and recycling more and wasting less is among them.”

Everything you ever needed to know about the Energy Price Cap, but were afraid to ask

Everything you ever needed to know about the Energy Price Cap, but were afraid to ask

By Sustainable Silchester’s Energy Expert

This week Ofgem, the energy regulator, announced the headline figure for the energy price cap would rise by around 80% to £3,549 per year. Given the amount of ill informed comment in the press and social media, I thought it was worth writing a short blog about what the energy price cap actually is and what it means for you as a domestic consumer (nothing written here is aimed at business use).

A Brief History of the Price Cap

The price cap was introduced in January 2019 with the purpose of ensuring that bill payers who, for whatever reason don’t seek out a cheap price for their gas and electricity, wouldn’t be too badly disadvantaged by unscrupulous energy companies. In other words, it seeks to reduce the cost of loyalty. The cap sets maximum prices for the standard variable rate that bill payers or moved to if they do not opt for an alternative deal. The expectation was that most competitive energy rates would be set well below the standard variable rate. The price cap was never designed to protect us from the impact of soaring energy prices. Indeed, there is some evidence that the question of what happens if energy prices rise above the price cap was not fully considered when developing this policy.

Roll on three years and we have seen the unintended consequences of this policy.  Over 60 suppliers have gone bust leaving less than 40 remaining. The standard variable rate is now the cheapest energy price most people can access. And the price of energy is becoming unaffordable for the much of the population. The price cap will not solve the cost of energy crisis, but it is still worth understanding what it means in practice.

So a price cap of £3,549 means I won’t pay more than this for my energy?

I’m afraid not. The £3,549 figure is based on an average house (3 bedrooms, semi-detached) and an average family (2 adults 2 children) using gas central heating. We pay for our electricity and gas in units of kilowatt hours (or kWh).  A kilowatt hour is a measure of energy, broadly equivalent to boiling a kettle for 20 minutes, leaving an LED light bulb on for a week or one tenth of a litre of petrol. Ofgem’s average home uses 2,900kWh of electricity and 12,000kWh of gas each year and this is used to calculate the headline figure. If you use more than this average amount you could end up paying substantially more than £3,549. If you use less energy you will pay less. Furthermore, it assumes you pay by direct debit, if you chose to pay by cash or cheque it could be up to £215 higher while a pre-payment meter may cost an additional £59.

If I’m not paying £3,549 what am I going to pay?

Alongside the headline figure, Ofgem also publishes actual energy rates for each area of the country.  These are divided into a standing charge (price per day) to pay for the costs of being connected to the gas or electricity grid and a price per unit of energy used.  For Silchester in the Southern electricity region our rates are:

  Gas Electricity
Energy Price 14.88p / kWh 52.07p / kWh
Standing Charge 28.49p / day 44.41p / day

So if you can find how many units of gas and electricity you used last year from your previous bills you can calculate your expected costs for this year. For a standard variable rate, gas and electricity customer paying by direct debit this would be around £266 + 0.15 x  [your annual gas usage in kWh] + 0.52 x [your annual electricity usage in kWh].

Does the price cap mean my energy bill is going to go up?

Not necessarily – many people are not on the standard variable rate, having chosen instead to fix their tariff for a period of months or years at an agreed rate. These rates are fixed for the duration of the contract and unaffected by the price cap.  Some energy companies are still offering fixed tariffs but they all tend to be significantly higher than the standard variable rate.  Still if you expect rates to go up further (as most commentators do) this might be a sensible option to protect yourself from future rises. 

I pay the same amount each month – how is this going to change?

Most energy companies now bill a fixed amount every month based on a projection of what you are likely to pay over the course of a year.  This means in the summer you pay more than the energy you actually use and in winter you pay less. Over the course of 12 months it should even out.

Energy companies have been criticised for significantly over estimating these monthly payments leading to people building up a substantial surplus – or (to put it another way) lending money free of charge to the energy companies. A change to the price cap provides an opportunity for energy companies to increase the amount they collect and you should be careful this increase is reasonable.   Divide the amount you expect to pay over the next year (see above) by 12, and if this is not close to what your energy company is proposing as a monthly rate you can challenge them and ask for it to be reduced. If you have any difficulty with this, then Citizens Advice Tadley can help.

Are we all doomed?

Few of us can easily afford energy bills of the level indicated by the price cap. Whilst the government is likely to provide more short term help over the winter, the fact remains global energy prices have risen massively and any reduction in bills is going to have to be paid for somehow, somewhen and by someone.

However, there is a lot that we can do to reduce our own energy bills.  Sustainable Silchester has plenty of advice on the topic, see Home Energy

An electrical device drawing only 1W left on all the time now costs £4.50 per year.  As fridges get older, the refrigerant leaks out, and they have to work harder to keep cool.  An old fridge might be costing you £450 extra every year, an you wouldn’t know that there is anything wrong with it. 

If you have a working smartmeter, now is the time to go round the house and check what is being left on, and how much energy it uses.  If you don’t have a smartmeter, Sustainable Silchester has a clip on meter that Silchester residents can borrow for a week to investigate.  Aim to get your baseload as low as possible – the average is about 150W, but below 100W should be achievable.

Glow Worm Hunt 2022

Glow Worm Hunt 2022

On Friday evening Stephen, from Sustainable Silchester, led a glow worm hunt on the Common

At 9:30pm on a Friday evening in July,   35 local people met outside the Calleva Arms for a walk on the Common to hunt for glow worms.  Stephen started by giving a short talk about glow worms.  After 3-4 years as larvae, glow worms have a brief mating season for a couple of weeks in July, before dying.  The female glow worms glow green in the night (like a small green LED) to indicate that they are ready to mate, and the much smaller male glow worms fly around to spot them.   Each female has her own, quite large, patch so we were unlikely to see more than one green light at a time.

We set out at dusk, and it wasn’t long before three of the children spotted the first glow worm in a small gorse bush.  As it go darker, we spotted more and more glow worms, and cries of “I’ve found one” rang round the Common as Erin rushed around trying to record locations for the record.  In total we found 20 glow worms, although I have to say the children were much better at spotting them than I was.

Time flew by (like a male glow worm?), and I was surprised to find that it was past 11pm when we turned for home.

Why does Sustainable Silchester run an annual glow worm hunt?

Glow worms are not rare in the UK and they are not an endangered species. As a result, they are never a priority in biodiversity or conservation action plans (for example, the current Hampshire Biodiversity Action makes no mention of glow worms). Silchester Common is a Site of Scientific Interest but it is not registered as such because of the presence of glow worms.

However, although glow worms are distributed throughout the UK they require a specific kind of habitat and that habitat is not present everywhere. We are lucky that we have some prime habitat for glow worms here in Silchester. That makes their presence in Silchester something unusual for Hampshire and something to celebrate. Although glow worms are not categorized as red list or endangered in the UK their presence has been declining steadily over recent years (for example, see the Gardiner Report, 2011: –  Glowing, glowing, gone? The Plight of the Glow-worm).

There is no real data on exactly why this is happening but some of the principal causes which have been cited include habitat loss, global warming and increasing light pollution. More scientific study is needed to understand each of these effects in more detail. A further complicating factor in relation to glow worms is that they need very different habitats in their different life stages. In the larval stage (which lasts around 3 years and makes up 95% of their lifecycle) the larvae build up food reserves, feeding exclusively on snails and slugs. This requires a habitat which supports lots of gastropods such as in the taller, closed vegetation provided by the gorse and heather on the Common. In the adult stage (when the female glows) the habitat needs change. The female needs open areas of grassland in which to display clearly. This is provided by the grass margins and the rides on the Common.

So, it turns out that the Common, with its mixture of habitats is perfect for the glow worm. Who knows what will happen, however, if global warming continues to happen and the Common dries up so that it does not support a good population of snails or slugs anymore. Or what might happen if more street lighting and/or domestic lighting encroaches onto the darkness provided by the Common (there are lots of studies to show that the more light pollution increases the less successful males are at finding females).

So, for all these reasons, Sustainable Silchester takes the view that it is important to keep monitoring the presence of glow worms and have a readily available database of sightings built up over time so that this data can be used when making future decisions about the management of the Common and any development which encroaches upon it.

Thank you to all those people who have come along and helped with this project. We intend to continue in future years as the glow worm walk not only produces helpful data but it is great fun – people who have not seen a glow worm before are often genuinely delighted to see one for the first time.


Getting Started with Refillables

Sustainable Silchester met Vikki from Ecosentials to find out how to get started with Refillables.

Refillables means topping up existing bottles and jars, rather than buying yet another plastic bottles.  Vikki is clearly passionate about the subject. “Not only do you use less plastic, but I choose environmentally friendly products that are kinder to the environment , better for  sensitive skin, babies and children.” 

So how does it work?

When you finish with a bottle, wash it out, remove the label, if you can and then drop it round to Vikki.   Vikki will refill the bottle and drop it back to you within a couple of days.  Vikki is based in Tadley, but also visits Silchester Market each month.  Any bottles dropped off at the market will be back with you by Tuesday. 

Some bottles are quite difficult to get the lid off, particularly duck shaped toilet cleaners, but Vikki was confident that she could get the lid off most bottles.

What are the most popular products?

Vikki didn’t have to think about that one!  The most popular products are definitely washing up liquid, laundry detergent and fabric softener, and toilet cleaner.  

A number of people have reverted to using bicarbonate of soda and vinegar to clean because there are no harmful chemical, and so she sells a lot of vinegar – often 3-5 litres at a time.  She also has a wide range of hand soap, shampoo and conditioner in different scents. 

Some customers just buy one type of product, and are happy with that, others buy from the full range.  Vikki doesn’t mind what people choose – every purchase is another bottle saved from landfill or incineration and that’s what keeps her motivated.

Sounds simple, why doesn’t everyone try it?

Well, a lot of people do!  Vikki has customers all round the area including Bramley, Sherborne St John, Baughurst as well as Tadley and Silchester, and many customers have been with her since the start.

The biggest barrier seems to be getting into the habit of hanging on to your empty bottle and dropping it round to Vikki, rather than putting it straight in the bin and adding another to the weekly shop.  However, once people get into the habit of refilling, they seem to stick with it, so Vikki knows that she is doing something right.

Retrofitting a Heat Pump

In November 2021, we decided to take the plunge, remove our gas boiler and have an air source heat pump fitted.  The main driver was to reduce our personal carbon dioxide emissions: our heating and hot water generated around 3.26 tons CO2 per year, and we thought that with a heat pump we could get that down to around 0.9 tons, and that this would reduce as the grid decarbonises.  However, I will admit that we were also curious as to how it would work.

A heat pump is essentially a fridge working backwards, extracting heat from the air and delivering it to our home.  If you burn gas in a boiler you get less useful heat energy out than the energy you put in.  The great thing about a heat pump is that, because it extracts energy from the outside air, you get more, useful heat to your home than the electricity you use to run the pump.  At least twice as much!  This ratio of heat energy out vs electrical energy in is known as the coefficient of performance or COP.  When it’s cold the heat pump has to work harder to extract heat from the air and therefore has a lower COP. As it warms up the COP also improves.  This graph shows how the manufacturer’s stated COP of our heat pump varies with the outside temperature:


The first stage to getting a heat pump fitted was to calculate the heat loss from our home.  Our supplier, Xpert Energy, created a model of our house, and calculated the heat loss through walls and roofs by room, both to give a total heat required to size the heat pump, and to that they could also check the size of radiator required for each room. 

We also had an air tightness test to check how airtight our home is.  This involved putting a large fan in our front door, raising the air pressure in the house slightly, and looking at how quickly this went down.  This was optional, but in our case worth doing, as our house is pretty airtight for its age, and having this evidence enabled us to buy a smaller heat pump.

Overall, the calculation said that at -3 oC, our house would need 6kW to maintain an internal temperature of 21 oC.

A heat pump is much more efficient when it is heating the water to a lower temperature, so the best strategy is to have larger radiators running at a lower temperature, or underfloor heating.  I had been afraid that every wall would need to be covered in radiators, but in the event about half our radiators were big enough already although we did decide to change most of them anyway.  The new radiators were all actually smaller and a little deeper than our existing radiators, so that was one fear allayed.

The installation took about 2 weeks.  It was more disruptive than it needed to be because of our decision to change all the radiators, and there is quite a lot of gubbins (technical term!) pictured below that we had to find space for.  On the positive side, we’ve gained a cupboard where the boiler used to be.  

We also had to have a new larger hot water tank. As the heat pump heats the water to a lower temperature than a boiler you need more water from your hot tap and less from your cold to fill a bath.  Fortunately, the larger hot water tank still fitted in our airing cupboard (just!).

I had been very nervous about how noisy the heat pump would be as Silchester is so quiet, but I think it makes less noise than the exhaust from a gas boiler.  So that was my biggest fear allayed.

We have a separate electricity meter for the heat pump, so we can see daily how much energy we used.   There is a very close correlation between external temperature and energy usage.  This is the data for November:

The benefit of this close correlation is that it is very easy to try different heating strategies, and quickly see the effect on energy usage.

For interest, I also looked at the correlation between our gas usage and external temperature.  This was our gas usage for November 2021:


Heating Strategy

We now have a thermostatic radiator valve (TRV) on every radiator, separate upstairs and downstairs heating circuits with thermostats, and the heat pump regulates the temperature at which it circulates water depending on external temperature.

We had been told that the most efficient way to heat our home was to leave the heating on at a steady temperature all the time.  This seems counter-intuitive.  Since the house loses less heat when it is at a lower temperature, surely it is more efficient to only heat it when you need the heating?

After experimenting for the last 3 months, I can report that they were right!

Initially, we tried to control the heating like we did with a gas boiler, setting the temperature to warmer in the mornings and evenings and cooler overnight and during the day.  However, we struggled to get the house warm at the right times.

After a while, we stopped changing the thermostats and reduced the temperature at which the water circulates round the radiators by a couple of degrees so that the thermostats rarely do anything.  The house got warmer, it felt more pleasant because the radiators were always on and the energy usage didn’t go up.  I’m told that in Sweden they don’t bother to fit thermostats to houses at all – the heating is simply controlled by sizing the radiators correctly and adjusting the water flow temperature and I can now see why.

I think that the reason is that reducing the temperature at which the water goes round the radiators by 2oC cut our energy usage by about 10%, which compensated for the slightly higher average temperature in our home.


One of our criteria for fitting a heat pump is that we didn’t want our energy bills to go up as a result, so how have we done so far?  January is traditionally the month in which our heating bills are highest.

In January 2021, we used 2741.9 kWh of gas, generating about 600 kg CO2

In January 2022, which had a very similar average temperature, our heat pump used 962 kWh of electricity, generating about 170 kg of CO2.

Utility prices are in turmoil, but at our current prices the energy used by the heat pump was 10% more expensive over the month than gas would have been (not counting the savings on the gas standing charge).   Since the heat pump is expected to be less expensive than gas as the weather warms up (I think the breakeven point is about 6oC), so far it’s looking about where we expected it to be.


Heat pump in situ

It’s taken a couple of months to get used to it, but we are very happy with our heat pump.

The temperature of the house is much more stable, and generally warmer than we used to have it when we had a gas boiler.  We cut our carbon emissions in January by about 400kg, and although not the most beautiful piece of kit, our heat pump is quiet and delivering the expected performance.

Repair and Restore

It’s much better to repair and item than to replace – both for the planet and for your pocket! 

John runs a small local company producing chemical products for the hobby industry.  He believes that we can all make a small contribution to improving the environment by repairing products and not throwing them away.  How often do you want to repair a precious item, or one that can’t be easily replaced?  What if you can’t simply buy a new on as it’s out of date or no longer available? Yet, with a simple repair it can be given a new lease of life.  Here John explains how he repaired a broken garage door operator.

A broken garage door operator made in hard plastic, (probably ABS) has broken so can longer be attached to a key ring. These cost £30-£40 each. It works perfectly so why buy another?

We built a small dam around the fractured area to contain the Fusion resin to be applied later.

We mixed the Fusion adhesive. It is a powder and liquid and mixed in a 1:1 ratio. Once mixed the mix is allowed to sit for a few minutes. During this time the powder dissolves into the liquid to create a liquid so slowly thickens. An adhesive tape was used to create and seal the base and thus form a dam to hold the Fusion mix in place while it cures.

The fusion has been poured and is now set (about 10mins). Importantly it is strongly bonded to black plastic case and has created a hard, tough, plastic material. It is far tougher and harder than epoxy so it can be filed or drilled even tapped with a thread.

COP26 from our own Correspondent – Week 1

Our own correspondent was at COP26 in Glasgow this week.  Here is his report on the first week.

COP26, or to give it its full name, the 26th annual Conference of the Parties to the United Nations Framework Convention on Climate Change, is currently taking place in Glasgow.   Our very own village correspondent has been there this week to bring you an exclusive report on week one.

This year COP is divided into distinct areas – the blue zone for the negotiations, managed by the UN; the green zone for selected companies to exhibit, managed by the UK, and a fringe event across all of Glasgow for everyone else, ranging from businesses to pressure groups to direct action protestors.  Over 50,000 people are attending the blue and green zones with many more being drawn to the fringe events.

The blue zone is where the main discussions take place and hosts the government negotiators and advisors; the non-governmental observers; the media; and around 100 mainly government sponsored pavilions providing presentation areas and meeting spaces.  Many of these pavilions organised a continuous programme of presentations, panel discussions and workshops, so in addition to the main negotiations and set piece speeches, at any moment there are perhaps 50 or more parallel sessions taking place on all aspects of climate change and what to do about it.  Many of these are live streamed and can be downloaded e.g. the UK Pavilion here and the US Center here.

While the main political declaration from COP won’t happen until the end of the second week, it has already been a tremendous success in advancing action to tackle climate change.  Probably the biggest change from previous COPs has been the position of business.  Previously most business leaders waiting on the side lines, not wanting to be the first to move.  Now it’s quite clear the starting gun has been fired and large businesses are competing to ensure they are not left behind on the pathway to sustainability.  This provides great grounds for optimism, because while governments can invest billions, business can invest trillions in tackling climate change.

Some of the notable announcements that you may have missed over the past week include:

  • Commitments to achieve net zero emissions from countries that have until now resisted setting climate targets including Australia and India.
  • 450 financial firms representing $130 trillion of investment committing to meet the goals set out in the Paris climate change agreement.
  • 100 countries pledging to end deforestation by 2030 including Indonesia, China, Canada, Russia and the US.
  • A pledge to cut emissions of methane by 30% by 2030 involving over half the world’s biggest emitters (methane is potentially 80 times as bad for global warming as carbon dioxide).
  • A commitment to end use of coal for generating electricity, signed by more than 40 countries including some of the most coal reliant.
  • The announcement of the Breakthrough Agenda to identify and track the developments needed to make clean and sustainable solutions the natural choice in power, road transport, steel and hydrogen.

So, despite some of the more downbeat press articles, the first week of COP 26 has achieved some noticeable successes.  These are best highlighted in the International Energy Agency’s assessment that, if all climate commitments made to date are delivered in practice, this would put us on a target towards 1.8 degrees temperature rise rather than the 2.7 degrees pathway suggested by the UN before COP26.  There’s a huge “if” in this projection and it’s still not 1.5 degrees, but it shows how far we have come.
