Air Source Heat Pumps at Bassetts Northern Ireland

Thinking about incorporating an Air Source Heat Pump into your home design? Our specialist heating engineers are on hand to chat you through any questions. Give us a call today.


Air Source Heat Pumps absorb heat from the outside air to heat your home and hot water. They are a greener, cleaner alternative to gas and oil, and can extract heat from air temperatures as low as -15°C!

Self-builders everywhere are falling in love with Air Source Heat Pumps. Your dream home deserves a heating system that fits your lifestyle. Studies have shown that Air Source Heat Pump and underfloor heating work excellently together in order to achieve cost-effective, environmentally-friendly and cosy warmth day after day.


An Air Source Heat Pump uses energy absorbed from the air and transfers it to the water based heating system via a vapour/compression cycle.

The process uses a refrigerant gas R32/R290 which has a low boiling point. When the R32/R290 gas is exposed to external air it heats up and compresses causing the temperature to increase. It then changes from a gas to a liquid before passing through a heat exchanger transferring heat to the heating system. As the heat is transferred to the heat exchanger the liquid changes back to a gas and the cycle is repeated.


Our heating design engineers have over 40 years of experience warming homes across the country. After researching numerous types and models of Air Source Heat Pumps, we are proud to have partnered with the best manufacturers and totally trust the brands that we stock. We are on hand to fulfil all of your home heating needs.

Benefits of an Air Source Heat Pump

You Control Your Heat Demand

By utilising ASHP integrated technology, you can smartly manage your heat demands to ensure optimum efficiency and satisfaction.

Quality of Heat

As opposed to the ‘blasts’ of heat provided by traditional heating systems and fuels such as gas and oil, ASHPs operates a ‘slow and steady’ kind of heat provision, offering high-grade consistent heat at lower temperatures. This is boosted further by better levels of heat retention in newer dwellings.

Saving on Energy Bills

In new homes, your Air Source Heat Pump operates between 25 – 30% more cost-effective than traditional heating alternatives.


Underfloor heating: this is our top choice for ASHPs as it is designed to run at a lower flow temperature, ideally 35 degrees.

Aluminium radiators: another great option – these are designed at a low flow temperature of 45 degrees alongside their high conductivity.

Steel radiators: these can work, however please consider their higher flow temperature. The size of the steel radiator must increase to compensate for the temperature drop which will reduce wall space.

Easy to install, run and maintain

Installation should take your plumber no longer than that of the installation of an oil boiler. Once set up by the commissioning engineer, you are good to go. Simply set your thermostat in each room and enjoy the benefits. Maintenance is to be carried out once a year and is clearly detailed in the service book.

Yes, here in Northern Ireland and throughout the UK we have a very suitable climate for Air Source Heat Pumps, as we very rarely get long periods of below minus temperatures, our average temperature in heating season is 7 degrees, which works well with Air Source Heat Pumps.

As we use Mono-Bloc Air Source Heat Pumps the servicing is very simple. You must ensure the ASHP unit is clean and clear of debris as in dirt, leaves etc. and make sure the magnetic filter is clean. We would recommend checking these twice a year.

A Mono-Bloc Air Source Heat Pump has all the refrigerant incorporated in the outdoor unit. A split unit Air Source Heat Pump has an outdoor and indoor unit which has the refrigerant running between the two units. A split unit must be serviced and checked by an F-Gas registered engineer annually. (Usually the charge for this service can be between £300 and £400 pounds annually).

Ideal location would be as close to the building as possible to avoid any heat loss from the unit into the building. Ideally south facing to avoid harsh weather and wind conditions.

Air Source Heat Pumps can be used with underfloor and/ or radiators. The underfloor or radiators must be sized to run at a lower flow temperature usually 30 – 45 degrees, to main the efficiency of the ASHP.

Yes, however Photo-voltaic systems work best with direct sunlight which is season dependant and usually not the months when we use our heating systems.

Yes, which is ideal for heating hot water during the summer months when we have a good amount of sunlight.

Not at all, Air Source Heat Pumps running at their maximum load, make no more noise than a dishwasher running. At one metre away it will be approximately 54db.

Air Source Heat Pumps run most efficiently at lower flow temperatures opposed to an oil or gas boiler running at higher flow temperatures. To retrofit an ASHP into an older dwelling, you may need to do additional work, e.g. upgrading your radiators, insulation, windows, ventilation etc. Air Source Heat Pumps will work and can run at a higher flow temperature, but in turn will be more expensive. Please bear this in mind when thinking of installing in a retrofit project. Our heating experts can best advise the optimum heating system for this.
