Electric heat pumps are significantly more energy-efficient than gas pumps by default, but there are still conditions which apply to that statement. Numerous variables such as usage, insulation, local climatic conditions, and the cost of units also affect yearly home and business energy expenses. Then, of course, there is the role of the heat pump itself.
How much money a heat pump will be able to save for you will differ depending on its type, make, model, and installation quality. Keeping all those factors in mind, it is still possible to get make rough estimates about what we can expect to save after switching over to an energy-efficient electric heating system. Let’s take a quick look at what the numbers may look like.
Residential: 25% – 27% Reduction in Heating Costs
Ever since the facts came out, numerous studies have been conducted by several parties to find out:
- If central heating pumps are more energy-efficient than their gas-powered alternatives.
- If the above is indeed true, then how much can we expect to save by investing in an electric heat pump?
On average, results indicate that residential properties can shave off as much as 25% – 27% of their annual energy expenses after switching over to an energy-efficient electric water pump.
Converting Percentages into Numbers: Close to £300 in Savings Per Year?
If we were to convert those percentages into numbers, the following should be the key points of consideration:
- If they are still using gas boilers, residential buildings in the UK pay about £984 in heating bills alone every year (average estimate).
- The average heating expenses come down to roughly £723 for similar households that are using an electric circulation pump or underfloor heating pump.
- Therefore, £261 is the exact, average amount that residential buildings can save per year from energy-efficient central heating pumps.
Note that the numbers will vary; these are only meant to help people understand what they can or should expect to save by making the switch. You will likely end up saving a lot more, or a bit less than what these numbers may suggest but rest assured that you will be paying less for heating.

How Do Electric Pumps Save More Money than Gas Pumps?
There are several reasons why electric boilers are cheaper to afford in the long run. Gas boilers cost more to maintain and repair, and they’re not as energy efficient as their electric counterparts. Even newly fitted gas boilers are said to be 90% efficient compared to the 100% efficiency of electric boilers. And, while gas has traditionally been the cheaper fuel option in the UK, the recent energy increases are meaning that homeowners are looking for ways to save on their bills. The cost of gas is also set to increase with the UK actively moving away from fossil fuels as much as possible.
