We installed a Clivet 10kw heat pump and 250L Cylinder, to replace an old inefficienct oil boiler. We also fitted a Planet device which allows us to track performance and monitor remotely. Its currently operating at a COP of over 5! That's 500% efficiency.
We replaced 3 boilers In this stunning 1930's property with a Samsung Gen 7 heat pump. We replaced the radiators with new victorian style column radiators to keep in with he look of the property. Its running open loop on a low flow temp, proving heat pumps can work in older properties too!

Boiler upgrade scheme.
Am i eligible?
The grant is actually quite a simple, straightforward process and something most homeowners can get hold of easily. We take care of the application for you.
You’re eligible for a grant if both of the following are true. You must:
-
own the property you’re applying for (including if it’s a business, a second home, or a property you rent out to tenants)
-
be replacing fossil fuel heating systems - such as oil, gas, electric or LPG (liquefied petroleum gas)
You’re still eligible if you’ve already had funding to make your property more energy efficient, for example by insulating it.
Your property must have a valid EPC to to obtain the grant. You used to have to have an EPC of a D or above, but this is no longer the case. New technology means heat pumps are capable of heating property's with poor insulation levels, although its still best to insulate as much as possible to maximise efficiency.

How does an air source heat pump work?An air source heat pump operates similarly to a fridge, but in reverse to provide heating for your home. It functions by drawing in outside air and passing it over a network of tubes containing a refrigerant. As the refrigerant interacts with the outside air, it undergoes a phase change from a liquid to a gas, absorbing heat in the process. This heat is then transferred to water, which becomes warm. Subsequently, this warmed water is circulated through your radiators or underfloor heating system, much like a traditional gas or oil-based heating system, effectively warming your home.
-
How reliable are air source heat pumps?Air source heat pumps typically have a lifespan of 20 years or more, provided they are properly maintained and receive regular servicing. This longevity makes heat pumps a highly appealing choice for long-term home heating solutions. Unlike traditional boilers and oil heaters, which rely on physical substances like fuel or water, heat pumps are designed to work with air, rendering them potentially more reliable in the heating context.
-
Are air source heat pumps cheaper to run than a boiler?The honest answer is, it depends! Heat pumps can be up to 500% efficient, meaning for every 1kW of energy put in, it generates up to 5kW of energy. For comparison, gas boilers typically run at 100%. Heat pumps run on electricity, which is currently around 3x more expensive than gas. That means as long as the heat pump is running at over 300% efficiency, then your running costs would be cheaper than a gas boiler. Its crucial the heat pump system is designed, sized, installed and set up correctly to make sure they run efficiently. We specialise in installing the most efficient heat pump systems! Long story short, if heat pumps are installed properly by a specialist, they are cheaper to run than gas boilers!
-
Are heat pumps noisy?Heat Pumps have come a long way, nowadays they are super quiet! During normal running operation, you won't notice the noise. There are short periods when the heat pump can be noisier, for example when defrosting or making hot water. During these periods it will be around 50-60dB, about the same as an extractor fan.
-
Will a heat pump keep me warm all year round?Heat pumps have a long-standing history and are engineered to function even in extremely low temperatures, as low as -27°C. In the United Kingdom, a meticulously designed system featuring a heat pump can 100% provide and sustain a comfortable indoor temperature all year round. The key factor lies in tailoring the system to suit your specific home.
