Pipe cover and depth in Ware extensions and conversions
Without the right screed on top, underfloor heating does not perform. It carries heat from the pipes to the floor surface, so it must surround every pipe with no air gaps, and it must be deep enough to spread the heat evenly and carry loads.
The minimum cover depends on the screed. Pumped liquid screed needs a 25mm minimum over the pipes, about 45 to 50mm all told. Hand-laid sand and cement wants nearer 45mm above them, adding up to a thicker floor. Extend the back of a Ware semi and the new floor must finish flush with the old one, so that 20mm gap often settles the choice.
Garage conversions pose the opposite problem. The old slab is usually low, so there is plenty of depth to fill, and a heated screed over insulation brings the floor up to house level while giving the room its heating.
The heating installer lays the pipes, clips them down and pressure tests the circuit before we arrive. When we turn up, we inspect what sits under and around them: edge strip, membrane, insulation. Any of those not yet down can be supplied through our work on membranes and insulation.
Detached houses make up 13% of homes in Ware, and larger ground floors in those homes are well suited to heating across the whole plan. On an open area like that, a flowing screed surrounds the pipes evenly.
Heat-up schedules for new floors in Ware
A freshly laid heated floor needs a rest before anyone turns it on. Calcium sulphate can generally take gentle warmth from around 7 days after pouring. Give sand and cement 21 days or more. Either way, the system is commissioned gradually: start at a low flow temperature, raise it a little each day, then hold it before cooling slowly. Rushing that process is a common cause of cracking, and so is switching on full heat to dry the floor faster before the schedule allows.
The heating also speeds drying, and calcium sulphate can be force dried with it from about 7 days. Flooring still waits for a moisture test, which our guide on drying times for screed explains.
Tiles, LVT and engineered wood all suit a heated floor, as long as the surface is flat and dry. Check each product's maximum surface temperature. 2026 UK published prices put a heated liquid floor at between £20 and £35 per m².
