What people in Cerne Abbas usually ask
Why use liquid screed over UFH rather than sand-and-cement?+
Liquid screed flows around the pipes with no voids, giving 20-30% better thermal response and lower running costs than a hand-laid screed. That's why most Cerne Abbas UFH installers recommend it.
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.
When can I switch the underfloor heating on in Cerne Abbas?+
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 Cerne Abbas clients to the schedule.
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.
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.
