Wet Underfloor Heating · Scunthorpe & Humber
Designed properly, manifolded properly, commissioned properly. The most efficient, most comfortable way to heat a ground floor — when it's installed by someone who actually understands flow rates, not just pipe spacing.
★★★★★Warmup, Polypipe and Uponor systems · Full design and commissioning · 10-year manufacturer pipe warranty.
Service overview
Radiators heat the air at the ceiling first. Underfloor heating heats the floor — exactly where you live. It runs at lower flow temperatures, which means a modern condensing boiler runs at its peak efficiency, and your bills drop while comfort goes up.
Design, supply and installation of wet (hot-water) underfloor heating systems — Polypipe, Uponor, Warmup. Manifold, mixing valves, actuators, room stats, screed prep guidance and full commissioning. Compatible with new boilers and heat pumps.
Homeowners building extensions, doing loft conversions, refurbishing ground floors, building new homes, or replacing storage heating across Scunthorpe, Brigg, Hull, Grimsby and Doncaster.
Best installed during new build, extension or major ground-floor refurbishment when the floor build-up is being redone. Also possible as retrofit with low-profile systems where floor depth is limited.
A correctly designed UFH system can be more efficient to run than the equivalent radiator system, distributes heat evenly across the floor, frees up wall space, and pairs perfectly with a future heat pump if you go that way down the line.
What goes wrong
When customers say 'we tried UFH, it never worked' it's almost always one of these:
Pipe centres set off a guess instead of a heat-loss calc means cold patches in big rooms and overheated bathrooms. Every loop should be sized to the room's heat demand.
UFH runs at 35–45°C — not boiler temp. Without a blending valve and weather compensation, the floor cooks and the screed cracks.
Without proper EPS or PIR under the pipes, half the heat goes down into the slab. Standard now is 75–100mm insulation depending on build-up.
Loops over 100m develop big pressure drops. Without balancing valves on the manifold, the short loops take all the flow and the long ones stay cold.
Plastic-bodied manifolds with poor flowmeters can't be balanced accurately. We fit brass-bodied manifolds with eye-level flowmeters as standard.
Thick carpet with foam underlay traps the heat at the floor. Engineered timber, tile, vinyl, LVT — all work brilliantly. We'll advise on TOG ratings before you choose flooring.
Our process
End-to-end — from heat-loss calc to commissioning the loops.
Room-by-room U-value calc determines the heat demand and therefore the pipe spacing and loop length.
Manifold position chosen, loop runs drawn, blending valve sized, controls specified. Drawings issued to you and your builder.
Itemised — pipe, manifold, insulation, controls, commissioning, all costs in writing before order.
Insulation laid, pipes clipped or stapled to plan, pressure-tested before the screed is poured.
We coordinate with your builder — pipes stay pressurised during the pour to flag any damage immediately. Cure time respected before commissioning.
Flowmeters balanced, room stats paired, blending valve set to design flow temperature, warm-up profile programmed, customer walked through controls.
Benefits
No cold spots, no hot radiator next to a cold window. The whole floor is the heat emitter.
Lower flow temperature = boiler running in full condensing mode — so it can be more efficient to run than an equivalent radiator system.
No rads, no TRVs, no pipe drops down walls. Furniture goes anywhere.
UFH is the natural partner for an ASHP. If you're keeping options open for a future heat pump, install UFH now.
No clicking TRVs, no ticking pipes, no creaking rads. Heat without a sound.
Less convective dust circulation than radiators — noticeably helpful for people with asthma or allergies.

In detail
UFH suits almost any build-up — new screed, low-profile retrofit, suspended timber floor — when matched to the right system.
Pipes stapled or clipped to insulation, 70–75mm sand/cement or 50mm liquid (anhydrite) screed poured over. Best thermal mass, evenest heat, quietest operation. Our default for new ground-floor builds.
Polypipe Overlay, Warmup Total-16, Nu-Heat LoPro. 15–22mm overall build-up — drops onto existing floors with minimal door-clearance issues. Best for refurbishments without screed.
Spreader plates clipped between joists with insulation below. Good for first-floor extensions or period properties where you can't add weight.
Brass-bodied manifolds with visual flowmeters on every loop. Actuators wired to room thermostats — programmable or smart (Heatmiser Neo, Hive Multizone). Weather compensation where the boiler supports it.
UFH works with any condensing gas boiler (modulating down to ~7kW preferred). Also the natural partner for an air-source heat pump — same low flow temperature, same control logic. Future-proofs the property.
Tile and stone: ideal. Engineered timber and LVT: excellent with the right adhesive. Vinyl: fine within manufacturer max temp. Carpet: works but loses some efficiency — keep total TOG under 1.5 (carpet + underlay combined).
Common in extensions — UFH downstairs, rads upstairs. Plumbed off the same boiler with a blending valve protecting the UFH circuit. We design the controls so the boiler still runs efficiently across both.
Small bathroom and en-suite floors are often better served by electric mat UFH than wet — quicker warm-up, simpler install, lower cost. We fit both and recommend whichever fits the use case.

For a typical 30m² kitchen-diner extension in Scunthorpe, wet UFH including manifold, controls and commissioning lands between £2,800 and £4,200 supplied and fitted (excluding screed). Whole-house ground floor for a 4-bed new build typically £5,500–£8,500.
No — the opposite. UFH runs at 35–45°C flow temp, which keeps a condensing boiler operating in full condensing mode. Typically 15–25% cheaper to run than equivalent radiator output.
Yes — low-profile systems like Polypipe Overlay add only 15–22mm to existing floor height. Best paired with a sympathetic floor covering choice.
Yes — most modern engineered wood is rated for UFH. We'll specify max surface temperature (typically 27°C) so the floor stays within manufacturer warranty.
Screed systems have thermal mass — they warm slowly (4–6 hours from cold) but hold heat well, so you run them continuously on a setback profile rather than on/off. Low-profile retrofit systems respond in 45–90 minutes.
If your boiler can modulate down to around 7kW (most modern combis can), yes. We add a blending valve to drop flow temp to the UFH design temperature.
Yes — every room has its own loop, actuator and thermostat. Programmable or smart controls available.
Every install — flowmeters balanced to design flow, blending valve set, controls programmed, warm-up profile dialled in. Customer walked through controls before we leave.
