Retro-fit heat pump
“Greenwave Renewables provided an excellent service regarding a retro-fit Heat Pump at our property. Their pre-sale care was excellent, they took great care to explain the Modus Operandi of their company, and the way they install Heat Pumps – which is important, because their approach is a crucially different approach to other heating companies. The installation went very smoothly for a large project, and the finished system has worked as originally described.”

“Absolutely amazing service! Greenwave Renewables came and surveyed our house thoroughly and provided full advice as to upgrades needed, and the right size and make of heat pump for our home. During installation the team were professional and friendly, and worked to a very high standard. Our new heat pump is now running, and our home is warmer that it was before! Could not recommend enough.”

Our FAQs
Got questions? Here are some of the most common queries about heat pumps and how they can benefit your home.
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.
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! When installed to a high standard and in the right property, heat pumps can be cheaper to run than gas boilers.
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.
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 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.
How can I get money off a heat pump?
You may be eligible for a £7,500 government grant via the boiler upgrade scheme. Theres no strings attached, just a few key criteria points to meet. This grant is only given out via MCS certified installation companies, to give the homeowner complete protection.
You may qualify for the Boiler Upgrade Scheme grant if all of the following criteria are met:
You are the owner of the property, for which you are seeking the grant, including properties used for business, as second homes, or properties rented out to tenants.
You currently have a fossil fuel-based heating system, such as oil, gas, or electric boilers.
Self Builders are eligible for the grant too!
