permanent heat and hot water


Extracting heat from the air around you can reduce your heating costs and generate extra income for you or your business. Air Source Heat Pumps (ASHPs) offer an attractive Return On Investment (ROI).  By installing ASHPs, you will be eligible for payments under the Non-domestic Renewable Heat Incentive (RHI). A typical ROI for an ASHP would be around 10 per cent with a payback period of around 12 years. For home-owners you may be eligible for the Domestic RHI scheme.

They did a first-class job. They didn’t cause any inconvenience and kept disruption to a minimum. It was business as usual while they were here. The team worked really well with the builders, joiners, plasterers, decorators, plumbers and everyone else involved in the project to make sure it went smoothly.

About Air Source Heat Pumps


ASHPs offer efficiencies of around 320 per cent compared to 400 per cent for Ground Source Heat Pumps (GSHPs) and 80-85 per cent for a typical commercial boiler.

The RHI payments are slightly lower than for GSHPs, however they are more affordable and easier to install.

Pure Renewables offers a one-stop-shop for ASHPs. Our in-house experts take care of every aspect of the installation and you get peace of mind, knowing that we are fully




accredited and have a track record of excellent customer service. ASHPs don’t require large areas of land, making them ideal for businesses on industrial estates or other confined locations. Their relatively low installation cost makes them attractive to companies on tighter budgets.
In order to maximise the benefits from an ASHP, your premises need to be well insulated to ensure they retain the heat generated, especially in winter.


Service goes to the heart of our offering as a business. From our initial design and consultation to our award-winning installation and aftercare, we focus on delivering a quality solution on time and budget.


Our legacy in renewables means our projects are efficiently designed and run. We deliver expert installations based on many years of experience. This experience means we can offer clients technically superior solutions that enhance the benefits of renewables.


All of our renewable energy services are focused on results and meeting the best possible heating requirements. Our knowledge of the full spectrum of solutions means we can deliver the best possible renewable energy outcome.

Air Source Heat Pumps FAQs


How do they work?
ASHPs absorb heat from the outside air, in the same way that a fridge extracts heat from its inside. There are two main types of ASHP: an air-to-water system distributes heat via your wet central heating system, while an air-to-air system produces warm air which is circulated by fans to heat your premises.


Is my property suitable?
ASHPs are ideal for new build premises, or well-insulated existing properties. You need space outside for a unit to be fitted, either on a wall or on the ground, where there is a good flow of air. The building should be well insulated and draught-proofed for best results and you will see better savings if replacing an electricity or oil heating system.


Will it work in winter?
The pump can get heat from the air even when the temperature is as low as -20° C. If temperatures plummet even further, the heat pump’s internal auxiliary unit will add the additional heat requirement. ASHPs come fitted with an auto-defrost function, so they can continue to produce hot water and heating in all weathers.


Will I save money?
ASHP technology has an energy efficiency rating of A***, which is the highest level for heating and water production.
How much you can save will depend on what system you use now, as well as what you are replacing it with. ASHPs work best with underfloor heating or large radiators and are cheaper to run than oil-powered systems and older inefficient systems. Our experts will explain how to control the system so you can use it most effectively.


What is the Renewable Heat Incentive?
The Renewable Heat Incentive (RHI) is a Government incentive scheme to encourage the uptake of renewable heat technology among businesses and homeowners.

The Non-domestic RHI was launched first in November 2011 to provide payments to industry, businesses and public sector organisations. The Domestic RHI was launched in April 2014, and is open to homeowners, private landlords, social landlords and self-builders.


What could I earn?
RHI cash payments are made quarterly over the applicable term of the scheme. The amount you receive will depend on a number of factors – including the technology you install and the latest tariffs available for each technology.


How reliable is the technology?
Our guarantees last up to five years and systems are expected to operate for 20 years or more.


Do I need planning permission?
They may be considered as Permitted Development, in which case you will not need planning permission, but it is always a good idea to check with your local planning office and to obtain written confirmation regardless of whether it is permitted.


Will it be noisy?
ASHPs have reduced in noise levels significantly over the last few years. Carefully sited pumps should present no disturbance to you or your neighbours and we follow strict MCS noise emission standards, which require careful emission calculations.



All renewable energy systems need to be designed so they are specifically tailored to the premises. This is essential to ensure you qualify for the Government renewable energy incentives such as the Feed-in-Tariff and the Renewable Heat Incentive.  We look at all aspects of your building so we can advise on how it can be made more energy-efficient and recommend the type of technology that suits you or your business.
