Will a heat pump work with my radiators?

Sometimes yes, sometimes the radiators need upsizing to run at the lower flow temperatures a heat pump prefers. We'll assess each room before install and tell you what's needed — it's usually cheaper to do it properly up front than to retrofit later.

Heat Pumps & Underfloor Heating in Dorset, Devon & Somerset

What we install

Renewable and low-carbon heating only makes sense if the design is right for the building. An undersized heat pump will cycle constantly; underfloor heating laid over poor insulation won't perform. We work through the survey first, not the product first.

Air-source heat pumps

For most homes across Dorset, Devon and Somerset, an air-source heat pump is the most practical move away from gas or oil. We size the unit to the building and household demand, assess whether radiators need upsizing to run at lower flow temperatures, and carry out the full install including cylinder, controls and pipework. For heat pump work we team up with a specialist MCS-accredited renewables company who specs, certifies and commissions the system, so where the job qualifies under the Boiler Upgrade Scheme the grant is accessible.

Underfloor heating

Underfloor heating pairs naturally with heat pumps because it runs at lower flow temperatures — which is exactly where a heat pump operates most efficiently. We install both wet (hydronic) and electric underfloor systems depending on what the project calls for.

For new builds and full renovations, a screed system is the most efficient option. For retrofits, low-profile systems can be installed over an existing floor with around 15–20mm added height — workable in most rooms. We survey the layout and insulation first and tell you honestly which approach makes sense.

Radiator upgrades for low-temperature systems

Most homes running old combi or system boilers weren't designed for the lower flow temperatures that heat pumps and underfloor systems prefer. We survey each room, identify where radiators need upsizing or replacing, and carry out the swap as part of the install. Getting this right upfront is what separates a system that works from one that disappoints.

Cylinders, controls and system efficiency

Unvented cylinders, buffer tanks, weather compensation, smart controls. The components that make a low-carbon system actually perform over time rather than just at commissioning. We spec what the system needs based on the building, not a standard kit list.

Frequently asked questions

Are heat pumps right for my home?

For most properties with reasonable insulation and space for an outdoor unit, yes. We survey the house, the existing system and your hot-water demand before recommending anything. Period stone cottages and poorly-insulated homes sometimes need work first — we'll be straight with you about what's worth doing.

What grants are available?

The Boiler Upgrade Scheme (BUS) currently offers £7,500 towards an air-source heat pump installation in England. Eligibility depends on the property and the install being MCS-certified, which we arrange through an accredited renewables partner. We can talk you through whether your home qualifies.

Can underfloor heating be fitted in an existing home?

Yes, though it depends on the floor construction. Screeded systems suit new builds or full renovations. Low-profile systems can go over existing floors with roughly 15–20mm of added height — workable in most rooms without door trimming. We survey first and tell you what's practical.

Will a heat pump work with my existing radiators?

Sometimes, sometimes they need upsizing to run at the lower flow temperatures a heat pump prefers. We assess each room before install and tell you exactly what's needed. Doing it right upfront costs less than retrofitting later.

How long does an install take?

A straightforward air-source heat pump install typically runs 3–5 days. Underfloor heating scope varies by room count and floor type — a single room might be a day's work, a whole-house screed system could be a week or more. You'll have a clear schedule before we start.
