Mixed-emitter
Underfloor heating and boiler integration in Somerset
UFH runs happiest at 35–45°C flow. Radiators want 50–65°C. Making one boiler serve both properly is a system-design job, not just a manifold on the wall.
For: Homeowners with UFH downstairs and radiators upstairs
How we make both work from one boiler
Blending valve on the UFH loop, low-loss header or zoned circulator setup, weather compensation on the primary. The result: even downstairs floors and hot upstairs rads, all from one boiler running efficiently.
What the integration covers
- Manifold and blending valve sized to the loop layout
- Zoned pumping or low-loss header where needed
- Weather compensation set to blended-mode curves
- TRV strategy on radiators for coordinated control
- Commissioning report with flow temperatures logged
Frequently asked
- Can one thermostat control both?
- Not well. Best-practice is a UFH programmable thermostat per zone and a smart room stat for the radiator side, both on the same schedule.
- Do I need a heat pump instead?
- UFH is heat-pump ready. If you're within 5–7 years of that upgrade, size pipework and emitters now to save later work.
- How disruptive is the install?
- For an existing system with UFH already in the slab, it's a single-day integration job. New UFH is a much bigger build project.
