Air Source Heat Pumps in Kent
Air source heat pumps are the most commonly installed type of heat pump in UK homes. They take heat from the outside air and use it to warm your home and provide hot water — even in cold weather. CPSL Kent has been supporting heat pump projects since 2017.
How Does an Air Source Heat Pump Work?
An air source heat pump absorbs heat from the outside air — even when it is cold — and transfers it into your home's heating system. It uses a refrigerant cycle to concentrate this heat and then distributes it through your radiators, underfloor heating or a hot water cylinder.
The outdoor unit contains a fan and an evaporator coil that draws in air. Even at temperatures as low as -15°C, the air still contains usable thermal energy. The heat pump compresses this energy to raise the temperature to a level that can heat water for your radiators and taps.
Because heat pumps move heat rather than generate it by burning fuel, they are significantly more efficient than traditional boilers. A well-designed system should deliver three to four units of heat for every one unit of electricity it uses — what engineers call a Coefficient of Performance (COP) of 3 to 4.
How Efficient?
Efficiency figures are approximate and will vary depending on system design, property insulation and outdoor temperature.
What Is Involved in an Air Source Heat Pump Installation?
Every installation is different, but here is a general overview of what is typically involved when CPSL Kent installs an air source heat pump.
Property Survey
We visit your property to assess heat loss, insulation levels, existing heating, hot water needs and available space for the outdoor unit.
System Design
Based on the survey, we design a system tailored to your property — choosing the right heat pump size, pipework routes and any upgrades needed.
Installation
The outdoor unit is positioned and connected to the indoor heating system. Most installations take two to four days depending on the complexity of the project.
Commissioning
After installation, we commission the system to make sure it is running correctly and efficiently. We also set up any controls and show you how to use them.
MCS Certification
If you are applying for the Boiler Upgrade Scheme grant, the installation needs to be carried out by an MCS-certified installer and meet scheme requirements.
Aftercare
CPSL Kent offers ongoing servicing and support after installation to keep your system running well for years to come.
Is Your Property Suitable?
Air source heat pumps are suitable for many types of Kent property, but not every home is ready straight away. Here are some things we look at during a survey.
Not every property is ready for a heat pump straight away. CPSL Kent will explain what is practical, what may need upgrading, and whether another heating or cooling option may be more suitable.
