ASHPs are a breath of fresh air

There are many benefits and reasons why an air source heat
pump may be better for your home than a new boiler.

  • Lower carbon footprint
    Air is one of the planet’s great natural renewable energy sources with no carbon emissions. What better way to use fewer fossil fuels and more renewable energy?
  • It pays to get one
    ASHPS qualify all homeowners for quarterly payments over the next 7 years term – worth up to £13,000 – through the Renewable Home Incentive (RHI) scheme.
  • Lower fuel bills
    ASHPs are cheaper to run than traditional fuels, with a typical saving of over 30% on oil and LPG.
  • More efficient
    By harnessing heat from the air, ASHPs are over 300% more efficient than a standard boiler.
  • Made for Britain’s climate
    ASHPs can still produce heat even when the air temperature outside is as low as -25ºC.
  • Low maintenance
    ASHPs simply need to be serviced every 12 months – to maintain your warranty.
  • Suitable for a wide variety of homes
    And easier to install than a ground source heat pump.

How air source heat pumps work

Air source heat pumps (ASHPs) are installed outside your home. They absorb heat from the outside air. This heat can then be used to heat your home’s radiators, underfloor heating system and hot water.

Compared to traditional heating systems like boilers, the carbon footprint of an air source heat pump is super low.

The most efficient ASHPs in the UK

Air source heat pumps convert energy from air into heat – to deliver very efficient, low cost energy saving warmth and hot water all year round.

The heat pumps we use are air-to-water. You won’t find a more efficient ASHP for low running costs, the Grant and Vaillant systems we install are market leaders.

Is an air-to-water heat pump suitable for my home?

Every home is different. We’ll need to ask you a few questions to see whether an air source system is suitable for your home, before arranging a free survey.

The market-leading heat pumps we use are air-to-water systems. They do not need an existing heating system as we will be able to provide a full heating system if one isn’t present. ASHPs do run at a lower temperature and due to this most existing radiators will need replacing to create enough heat for each room. This will be discussed at point of sale and calculated after a technical survey.

Air source heat pumps work well with traditional as well as underfloor heating. During your survey and at installation, we will design a bespoke heating system for your home to meet all of your home and family’s heating needs.

If we believe the system isn’t suitable for your property or won’t suit your usage requirements – we’ll let you know and the reasons for this. This service is completely free of charge and with no obligation.

How long does it take to install the pump?

It only takes a few days to install an ASHP and it causes much less disruption when compared to ground source heat pumps, for example. This is because there are no buried underground coils, so they can be easily integrated into existing properties.

You’ll be advised how long it takes during your free survey – if you want to spread the cost, ask us about finance on air source heat pumps.

How is the Renewable Heat Incentive (RHI) for air source heat pumps calculated?

As part of the UK government’s commitment to cutting carbon emissions, the Domestic Renewable Heat Incentive (RHI) encourages more people to replace costly heating systems – such as oil, LPG and electric – with a cleaner, greener, efficient and cheaper to run system. The incentive is quarterly cash payments over 7 years – worth up to £13,000.

Our expert will design your system during your free home survey. This gives you the cost of the air source heat pump system and your RHI estimation. It is calculated with the SCOP (Seasonal Coefficience Of Performance) and the kWh needed to heat your home and hot water, multiplied by the current tariff to generate how much you’ll receive each year. Once your air source heat pump is installed, we inform MCS and Ofgem and a ‘Date of Application’ email is produced within 7 days. At this point, your tariff is set (it can go up if the tariff rises but will not come down if it decreases).

You’ll receive your first quarterly payments around 3 months later. Other incentives are also available; you can claim an additional £1,610.

  • "Save up to £350 on your energy bills, every year! **"

  • "Recently had Solar fitted, and from day one up until install I am pleased with my experience with Effective Home, I've never experienced a virtual survey before and at first I was curious about it, but it was straight forward with no hassle and want to praise the company for doing a great job! "

  • ""I was worried that I was dealing with an "office" hundreds of miles away from me. As it transpired this was not a problem. The negotiations were formal yet friendly. The idea of having a link person who you can contact easily was a great idea. It didn't always work, particularly when I was trying to get dates settled. Once agreed, the scaffolding and solar panel completion went very well, with great guys doing the work.""

  • "From start to finish brilliant. From assessor to fitter. We are very happy with the work - excellent service. They said they were going to do it in a day, and they did. They did not get in the way once."

  • "Above and beyond! The work was done to a high standard. No extra cost, right on the quoted amount. I'm always sceptical about these sort of things, but I'm extremely happy."

  • "They replaced an external oil fired boiler for us - it was the first time we had used them but we would be willing to use them again as they definitely lived up to our expectations."
