How Does a Heat Pump Heat Water?
Think of a fridge working in reverse. Outside air is pulled over an evaporator, the refrigerant soaks up its warmth, the compressor concentrates it, and a coil hands it to the stored water. Because it moves heat rather than making it, it uses less electricity than an element.
For a household here, that means:
- Lower running costs than an old electric storage tank heating the same water
- Provided the unit is rated for cold mornings
- Since the unit needs open air around it
Area-level figures count 390 heat pump installs, alongside 426 solar hot water systems.

What Shapes the Heat Pump Quote?
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.
"Communication was excellent, the quote was clear, and the work was completed promptly." Lily
The figure rests on:
- Tank size Matched to how many people shower and when
- Where it goes Since a new slab or a long pipe run adds labour
- The existing supply Because an old galvanised line may need replacing first
- Removing the old unit Harder when it is wedged in a tight cottage cupboard

When We're Not the Right Call
A heat pump needs a suitable power supply, and wiring in or upgrading that supply falls to a licensed electrician. The plumbing follows once the power is ready, and a gas system is handled through gas fitting instead.
Heat Pump Questions
Will a heat pump keep up through a Greta winter?
Yes, when it is sized properly. Modern units keep drawing heat from cold air, and the tank is chosen so it recovers even after an icy night. Sizing to the household is part of the quote.
Can an old cottage cylinder be swapped for a heat pump?
Yes. The supply is tested first, because some older homes still run galvanised pipe that has narrowed with scale. If part of that line needs replacing, it is priced alongside the heat pump.
Do you repair heat pumps as well as install them?
Yes. A unit that has stopped heating is diagnosed first, since the cause can be a valve, a sensor or a setting rather than the whole system. If it cannot be saved, replacement options are priced before anything is removed.
Where does the unit go on a small block?
Outside, on a slab or wall bracket with clear air around it and within a short run of the plumbing. On the narrow blocks of the old grid that can mean a side passage or the back wall, and the spot is agreed with you on site.
