Heat pump questions
What is a heat pump?
Air source heat pumps are highly efficient, renewable energy systems. They heat your home and hot water using energy from the air outside even in the depths of winter. Quiet and easy to use, they don’t need much maintenance once installed and could save you money on your energy bills.
If you want the finer details about heat pumps work, read on.
Are heat pumps noisy?
Like any machine, heat pumps make some noise. However, you might be surprised by how quiet they are. Most heat pumps generate sound that is same as the gentle hush of a library or the sound of breeze through the leaves of a tree.
If you'd like to see just how quiet heat pumps are, read on.
Are heat pumps efficient?
Air source heat pumps are one of the most efficient heating systems for your home. They can generate up to three times the amount of heat for every kw of energy used. This makes them highly efficient compared to your traditional boiler. Heat pumps are sustainable and could also help you save energy.

Do I need to replace my radiators?
Not always, no.
However, if you do not replace unsuitable radiators, your heat pump may not work as efficiently as possible. Heat pumps operate at a lower flow temperature to traditional gas boilers. This is one of the reasons they are so highly efficient. To maximise efficiency, heat pumps require radiators with as large a surface area as possible.

How much room does a heat pump need?
You will need space outside your home for the external unit as well as inside space for a hot water cylinder. Our expert team will design the best system for you and your home.
I’m planning a renovation or extension; can I still get a heat pump?
Yes!
Our team can work from plans to design your heat pump system. Get in touch today and we will talk you through the process.
Will a heat pump keep me warm in winter?
Your air source heat pump is great for the UK climate.
It will keep you warm even when outside temperatures drop to -28°C. It may work a little harder but you will still be warm and cosy in your home.
