What is an Air-Source Heat Pump (ASHP)?
Also known as an Air-to-Water Heat Pump, the Air-Source Heat Pump is a device that uses energy in the air to boil a refrigerant by passing air across an evaporator. The heat pump looks very similar to a traditional Air Conditioning unit.
What types of Air-Source Heat Pump do Gregor install?
There are two main types of ASHP: Monobloc and Split system.
Monobloc heat pumps
The whole heat pump is enclosed within the casing. The heat pump is generally fitted on an outside wall with clear air flow across it. It can come in various power outputs; and some models are single-fan units while others are twin-fan units. The unit is fitted onto rubber feet. Twin 28mm Flow and Return pipes enter the building and connect into the central heating system.
Split system heat pumps
The system is split with the outdoor evaporator being connected to the indoor unit with two pipes, one for gas refrigerant and one for liquid refrigerant. The outdoor unit can be located up to 20m away from the indoor unit. These systems are desirable if the customer doesn’t want the evaporator near the house or doesn’t have any suitable space.
What makes of Air-source heat pump do Gregor install?
We install air-source heat pumps by Daikin and Mitsubishi. There is further information below. However, if you would like to find out more, don’t delay, call Gregor today on 0117 935 2400.
Gregor install Daikin split systems. Daikin have considerable experience in the commercial heating and cooling market, from which the domestic product has been developed.
Daikin offers a range of sizes from 4kW to 16kW. Gregor are a premier installer for Daikin and can offer a comprehensive 5-year warranty on the Daikin products.
To heat domestic hot water, Daikin offers a range of cylinders including integrated cylinders and indoor units. These offer an aesthetically pleasing appearance and are a good solution where space is at a premium. They look similar to a white goods product such as a fridge-freezer.
Gregor install both types of system and only use leading brands. For the monobloc systems , which make up around 80% of our installations, we use Mitsubishi. These come in a range of sizes from 5kW to 14kW. Gregor are a premier installer for Mitsubishi and so can offer a comprehensive 5-year warranty on the product.
To heat domestic hot water, a heat pump cylinder is fitted. We prefer to install the Mitsubishi pre-plumbed cylinder with the heat pump. These come in a range of sizes from 150 litres to 300 litres. Solar heat pump pre-plumbed cylinders and slimline variants are also available.
What Government Grants are available for Air-Source Heat Pumps?
Starting from 23 May 2022, you can apply for a one-off grant of up to £5000 towards the cost of installing any new air-source heat pump whose installation commenced no earlier than 1 April 2022. This is possible under the government’s new Boiler Upgrade Scheme, the replacement for the Domestic Renewable Heat Incentive scheme, which closed to all new applications on 31st March 2022.
The BUS is only available to homeowners who have first met the home insulation recommendations in an EPC report. Certain other eligibility criteria may apply; see here for details.
