Merriott Underfloor Heating Screed Specialists
Underfloor heating only works as well as the screed encasing it — and in Merriott that means a high-thermal-conductivity liquid pour that wraps every pipe with no voids.

Underfloor heating only works as well as the screed encasing it — and in Merriott that means a high-thermal-conductivity liquid pour that wraps every pipe with no voids.
The screed self-levels around every loop, eliminating the voids you get under hand-laid traditional screed. That means the floor responds faster when the heating calls for it, and stores less wasted heat.
Most of our Merriott jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Merriott sits Taunton (16 mi), and we work the surrounding villages on the same week's diary.
Underfloor Heating Screed in Merriott — how it works
The screed self-levels around every loop, eliminating the voids you get under hand-laid traditional screed. That means the floor responds faster when the heating calls for it, and stores less wasted heat.
For Merriott UFH builds the typical sequence is: insulation board down, pipes clipped and pressure-tested, edge insulation in place, then we pump and level in a single visit.

How a Merriott pour runs
- 1
UFH installer fits manifold, pipes and pressure-tests to 6 bar
- 2
We confirm edge insulation, DPM and pipe coverage depth
- 3
Pump and level the screed with pipes still under pressure
- 4
Slow commissioning of the heating — usually after 7 days, ramping per manufacturer spec
- 5
Floor coverings once moisture is signed off and commissioning is complete

Specifications suited to Merriott builds
Cemfloor Therm
Liquid screed engineered for UFH — lambda 2.1 W/mK, fast response.
PIR/Phenolic insulation board
70-150mm typical depending on build regs U-value target.
Edge insulation strip
Critical around UFH zones to allow thermal expansion.
Pressure-testing kit
Pipes held at 6 bar through the pour to flag any damage immediately.
FAQs from Merriott clients
What if a pipe leaks during the pour?+
Pipes are held at 6 bar through the pour. Any pressure drop is flagged immediately and we stop, fix and continue — this is exactly why we keep the manifold under test.
Will the screed crack as the UFH heats up?+
Properly isolated at the edges and at doorway joints, no. We pour with the pipes pressure-tested and follow a controlled commissioning schedule.
Does liquid UFH screed improve EPC ratings?+
Indirectly — yes. Faster response and lower running temperatures help heat-pump COP, which feeds into your SAP/EPC. We'll share the manufacturer data your assessor needs.
What depth of screed over UFH pipes do you recommend?+
Minimum 50mm cover above the highest pipe — usually a 65-75mm total slab over insulation. Thicker if you want more thermal mass.
When can I switch the underfloor heating on in Merriott?+
On Cemfloor Therm we typically start a slow commissioning cycle from day 7, ramping 5°C per day per manufacturer spec. Forcing it earlier risks cracking, so we hold Merriott clients to the schedule.
Can you pour over a heat-pump system in Merriott?+
Yes — and we'd argue you should. Heat pumps run at lower flow temperatures than gas, so the screed's thermal conductivity matters more, not less.
