Practical heat pump guidance, in plain English
Practical answers on suitability, radiators, hot water, costs and living with a heat pump.
Will a heat pump work in my home?
Start here if you are still deciding whether it is worth exploring at all.
Is my home suitable for a heat pump?
Five practical questions decide it, and none of them is about the product. A “not yet” is about today’s building, not a permanent verdict.
Heat loss explained, without the maths
The room-by-room calculation that sizes the heat pump and every radiator in the house — and why your old boiler’s output is the wrong place to start.
What might need changing?
The parts of the house a heat pump actually touches.
Will I need new radiators?
Some of yours are probably already big enough and some are not. It is a room-by-room answer, and the aim is the smallest change that works.
Hot water and cylinders
What changes when you leave a combi boiler behind, how a cylinder is sized, and where one can realistically go if you have no airing cupboard.
Planning a heat pump into a renovation
The cheapest moment to do it, the three decisions that are expensive to reverse once the floors are down, and how to stay heat-pump-ready if you are not ready yet.
What will it cost to run, and what help is there?
What actually drives the number, and where financial support fits in.
What determines running costs
The five things that actually decide it — and an explanation of why we will not put a figure on your future bills.
Weather compensation and controls
Why a heat pump should run gently for hours rather than blast and stop, and why switching it off when you go out may not save what you expect.
Adding solar or a battery
Solar peaks in summer, heating peaks in winter. Where the combination genuinely earns its place, and where it does not.
How grant funding works, in principle
The mechanism, not the numbers: who applies, why installer certification matters, and what Airwarm can and cannot confirm today.
Living with a heat pump
Once it is in: keeping it right, and what to do when something is not.
Servicing and maintenance
What an annual service actually checks, why it protects efficiency as well as your warranty, and the four things worth doing yourself between visits.
Common problems and what causes them
Most complaints are not equipment failures. How to tell a fault from a design issue, and what can still be corrected on a system someone else installed.
The pages behind the advice
These guides describe how Airwarm works. These pages describe the service itself.
