Air Source Heat Pumps

A Sustainable, Modern, Cost-Effective Alternative Heating Solution

Air Source Heat Pump

What are Air Source Heat Pumps and how do they work?

Air Source Heat Pumps (ASHPs) are becoming increasingly popular in the UK. The technology presents a great way to heat your home and domestic hot water while significantly reducing your energy bills and carbon footprint. Working in a similar way to a refrigerator, but in reverse, the device absorbs heat from the outside air and transfers it to another medium. Resembling an air conditioning unit, it sits on concrete paving slabs outside your property and is plumbed in to connect with your hot water and heating system. Savings vary depending on your current fuel source.

Air Source Heat Pumps date back to the 1850s, however, about 3 and a half years ago, there was a leap forward in the gases and mechanics, which has dramatically improved their efficiency. In 2021, for every kilowatt of electricity you put in, you get 3.5 to 4 kilowatts of heat out. Impressive right?

The key benefits to using an Air Source Heat Pump

Air Source Heat Pumps are an incredibly efficient way to heat your home. They can work on their own or in partnership with your existing central heating system, creating an alternative to conventional gas boilers or off-grid fuel such as oil or LPG.

Kentish Plumbers work with Enlightened Solar as they are an MCS-accredited installer of Air Source Heat Pumps. MSC accreditation is an independent certification scheme that authorises both microgeneration products and installers, and it specifies that all Heat Pumps must last in excess of 20 years. It’s a sign of quality, giving you peace of mind and assurance.

In terms of running costs and savings, an Air Source Heat Pump is one of the best options on the market. Let’s say you are paying 16p per kilowatt-hour for your electricity. If it has gone through a Heat Pump, you’ll be paying just over 4p for every kilowatt-hour of heat that you’ve got. Homeowners with an oil boiler will be paying about 7-8p per kilowatt-hour for heat, and if you’re on Calor gas, it’s even worse.

After a full survey, a heatloss calculation is undertaken to determine the size of ASHP most suitable for your house. Because Heat Pumps run at a lower temperature (45-50°C) you might need larger radiators installed. It’s all to do with surface area and we can upgrade your radiators, if required – all at 5% VAT.

Kentish Plumbers’ technicians will come to your house, take out your gas boiler and replace the system with a Heat Pump, which sits outside. We may also need to change your hot water cylinder to a new one that is designed to work with the new technology. These stainless steel cylinders have a 25-year warranty and can de set up to provide mains pressure to your house, and thus create power showers. Your old water tank in the loft will no longer be required, removing any risk of water contamination.

Oil and gas-powered radiators run at 60°C, causing stratification within a room – a lot of hot air right by the ceiling. For tall people, this results in a hot head and cold feet. An ASHP radiator at 45°C is a much more comfortable temperature. It warms the room, spreading heat evenly, without creating this kind of stratification. ASHP are also ideal for Underfloor Heating.

Heat Pumps require very little maintenance. Once a year, the mechanical device needs a simple service, which Kentish Plumbers’ experienced technicians can perform for you.

Eligible for Government Renewable Heat Incentive

Installations registered before 31 March 2022 can benefit from the Renewable Heat Incentive – a government grant of up to £11,500 that’s paid as a contribution to installing a Heat Pump. These payments have been compressed from over 20 years into just 7 years, making it a big cash incentive. Some criteria must be met, which involves correct loft insulation or cavity wall insulation. Check your availability here. The RHI is tax-free and index-linked. The payments are based on the energy requirements for your house, derived from your EPC.
