Can you pour over a heat-pump system in Lympstone?

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.

When can I switch the underfloor heating on in Lympstone?

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 Lympstone clients to the 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 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.

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.

Devon Coverage

Liquid Screed Pours Across Lympstone & Nearby

We pour Cemfloor liquid screed across Lympstone, with a 30-mile working radius covering Nutwell, CTC Lympstone perimeter trades and the wider Devon area.

We're Lympstone is an estuary village with damp-aware retrofits and Commando-base support work. Our coverage runs across EX8, taking in Nutwell and out toward CTC Lympstone perimeter trades, with the M5 (J30, ~6 mi) on hand for materials and pump trucks.

Most of our Lympstone jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Lympstone sits Exeter (8 mi), and we work the surrounding villages on the same week's diary.

Built for Lympstone coastal residential and hospitality clients

Lympstone is a coastal town, so damp control, salt exposure and tight winter pour windows shape every brief. We work the diary around that — and around the holiday-let turnover that funds half the jobs here.

Liquid screed in Lympstone — how it works

Build-up is straightforward: insulation, DPM, edge isolation, pour. We handle the lot or we work to the main contractor's substrate — whichever suits your Lympstone job.

On larger Lympstone jobs we mobilise a static mixer; on residential we use ready-mix delivery and a smaller pump. Either way, the finished floor reads the same.
