Heat pumps take energy from the outside and transfer it into heat to be circulated around a heating and hot water system. An air source heat pump uses electricity to transfer the energy from the heat source into the heating system.

Here’s why they are becoming much more popular: 

They reduce your bills permanently

They are more efficient than gas boilers

You can produce energy how you want, when you want

They help protect the planet using energy efficient heating methods

Air Source Heat Pumps are the way of the future, but we can enjoy these benefits here and now.

The Energy Company Obligation currently supports heat pump installation alongside a variety of whole house retrofit energy-saving measures. We will introduce you to fully-registered heat pump installers in your area; Find out if you are eligible for heat pump funding supported by your energy suppliers and let Residential Energy Services take care of the rest.

Air source heat pump benefits

Stay warm and comfortable all year round

Air source heat pumps make your home cosy in the winter so you’re always comfortable and won’t need to put on too many layers!

Reduces the need for expensive energy

When you use a heat pump you lower energy bills by drawing energy from natural resources in the environment around your home.

Health benefits

Having greater control over the temperature leads to less erratic temperature fluctuations and temperature related illnesses like cold and flu.

Healthy environment

Heat pumps use less energy than traditional heating systems, which is better for your carbon footprint and better for the environment as a whole.

Reduced to maintenance

These days, heat pumps require little to no maintenance to carry on working throughout the year, even during the most difficult months.

They run quietly

Nowadays, modern heat pumps won’t disturb you, your family or your neighbours. They make very little sound, even when running at max capacity.

Heat Pumps FAQ’s

How do heat pumps do their job?

There are two kinds of heat pump we can assist with: air source and ground source.

Air source is the most common. They work by using a compressor to pull latent heat from the air or ground and raise it to a temperature that can be used. For air source heat pumps, the heat is spread by a fan, or the heat pump is connected to your radiators. In the summer, air source heat pumps can be run in reverse to pull heat from the air and pump it into your home.

Heat pumps only need a small amount of heat energy to start, and air source heat pumps can pull heat out of the air at temperatures as low as -15 degrees C.


Will a heat pump be enough to heat my entire house?

Yes, if it’s the right size. It doesn’t make much sense to replace your heating system with one that is too small for your needs. A good system designer will think about how much heat your home needs and make sure the heat pump they suggest is big enough to give you the required heat suitable to your home and usage. But because heat pumps produce heat at a lower temperature, you should also make sure your house is well insulated and increase the size of your radiators, sometimes by 15%.

How much does it cost to buy a heat pump?

The price of a heat pump depends on the type (air source heat pumps are the least expensive) and, of course, the model and manufacturer. They are not cheap, but if you buy a good brand, it should last you for a few years without giving you any trouble.

Funding may be available to install an air or ground source heat pump in your home. Contact us today to find out if your home qualifies for funding.

How long does it take to install a heat pump?

It depends on the type and on the property. As a general rule, installing an air source heat pump takes about 3 days. A system with no pipes and no ducts can be set up in as little as one day. Depending on how much pipework is needed and whether you are digging a trench or a deep borehole, a ground source heat pump will take longer because it requires more drilling.

Can you set a heat pump to come on at certain times to heat your home?

Yes, just like any other heating system, it can be used whenever you want. Set your thermostat and timer, and your heat pump will heat your home when it’s needed. Some people think that running heat pumps on a low setting all the time in the winter is more efficient, but opinions are split on this. If you have questions about heating controls, it’s best to ask your installer because they will know how to run your system best.

How long does a heat pump last?

If they are taken care of, heat pumps can last for 15 to 20 years or even longer.

What kind of upkeep does a heat pump need?

If you don’t take care of your heat pump, its efficiency can really go down. Some parts should be checked and cleaned regularly. You should clean and replace any filters and wipe down the coils and fans (after turning them off) as directed by the manufacturer.

Are heat pumps a way to get energy from a renewable source?

They are much greener than other ways to heat a home because they get heat from natural sources. However, the compressor still needs electricity to run. Heat pumps are a good choice if you want something that saves energy and is good for the environment.

What funding is available?

ECO4 funding is available for heat pump upgrades in certain areas, check if you’re eligible for heat pump funding here.

Air Source Heat Pump Grant

What is a free air source heat pump grant?

ECO grants are funds being provided to help individuals with the lowest incomes insulate their homes, as well as those who live in the least energy-efficient homes or the lower council tax bands.

How do grants for free air source heat pump’s work?

First, eligibility is determined by a number of factors including household income, EPC rating and whether or not you are receiving any current government benefits. Residential Energy Services then work to determine suitable energy efficiency measures for your home. We also work with a trusted network of partners to help ensure those measures are delivered correctly.

How do I apply for a air source heat pump grant?

Contacting Residential Energy Services is the quickest and most straightforward way to find out if you qualify, compile your eligibility criteria and approach energy providers to obtain air source heat pump grant support.

How much can I get from an ECO grant?

Under the ECO4 scheme, free home energy efficiency upgrades are available to eligible homes. The awarding of grant funding is entirely dependent on determining the right measure for your home at this time.

I already receive government funding; can I apply for an ECO grant?

You may still be eligible for ECO4 funding. Our friendly energy advisors can talk you through the eligibility checking process and advise on the most suitable funding for you and your home.

Who pays for air source heat pump improvements to my home?

The Energy Company Obligation is a government scheme deployed by energy suppliers who fund energy efficiency measures for your home, delivered by ECO approved installers.

Who decides what measures I’m suitable for?

It is ultimately the decision of the energy supplier to determine which measures are best; however, a home energy assessment with Residential Energy Services can make this process more accurate, relevant and efficient, to make sure you’re getting exactly the support you need.
