Barn conversion heating systems across Somerset
Barn conversions almost never have the same heating brief as the original house. Volume, glazing ratio, and mixed-material walls change the heat-loss calculation completely — and a like-for-like boiler upsize is rarely the right answer.
Underfloor is usually the right call
Big open volumes love the even, low-flow-temperature output of underfloor heating. That in turn suits a modern condensing boiler running at 45–50°C flow, or later, an air-source heat pump. We plumb it so both work today and tomorrow.
Included in the conversion install
- Room-by-room heat-loss on the drawn plans
- Manifold, zoning and thermostat plan
- Boiler sized for real load, not headline kW
- Low-loss header where multiple zones justify it
- Wiring, controls and commissioning documented
Future-proofing for a heat pump
If you might swap to an air-source heat pump in five years, sizing the pipework and emitters for low flow temperature now avoids ripping it all back out later. We build that in as standard on conversions.
Frequently asked
- Should I use underfloor everywhere?
- Usually yes for ground floor, radiators upstairs — best of both. First-floor underfloor is doable in a new build but rarely justifies the cost in a conversion.
- What fuel makes sense?
- If mains gas is nearby, that. If not, LPG or oil with a heat-pump-ready system for later. We'll model both on the survey.
- Who coordinates with the builder?
- We do — first-fix, second-fix and commissioning slot into the build programme without you playing project manager.
