Heat Pumps, Underfloor Heating & Air Conditioning 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.

Air conditioning

Not strictly a renewable technology, but it belongs here because modern air conditioning units are reverse-cycle heat pumps. They cool in summer and heat in winter, typically delivering 3 to 4 units of heat for every unit of electricity used. For specific rooms where you need reliable temperature control, they're often the most practical answer: south-facing bedrooms, conservatories, home offices, garages, and holiday lets where guest comfort matters.

We install wall-mounted split systems for single rooms and multi-split systems for several rooms from one outdoor unit. F-Gas registered, free home survey, prices from £1,750. If you're refurbishing and want climate control in a specific room, it's worth planning the install before the room is finished.

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.

Why OWB for renewables and climate control
