Underfloor heating installation

In most cases yes. A wet underfloor system runs at a lower flow temperature than radiators, so it is connected through a mixing manifold that blends boiler flow down to the design temperature. Modern condensing boilers actually run more efficiently at the lower return temperatures underfloor heating produces.

Wet systems are the right choice for whole rooms and whole houses because they are far cheaper to run on a per-square-metre basis. Electric mats make sense in smaller areas such as a bathroom or en-suite where pulling a wet loop back to the manifold is disproportionate.

We use either a traditional sand and cement screed at around 65 to 75 millimetres, or a liquid (anhydrite) screed at around 40 to 50 millimetres. Liquid screed gives faster installation, better contact with the pipes and quicker drying, and we recommend it where headroom or programme is tight.

Sand and cement screed needs roughly one day per millimetre of thickness to dry to a moisture content suitable for floor finishes, so around two to three months for a typical depth. Liquid screed dries faster, often inside four to six weeks, and we run a controlled commissioning cycle before any moisture-sensitive finish goes down.

Yes. Low-profile retrofit systems sit in routed boards or thin overlay panels at around 15 to 22 millimetres total build-up, so floor levels do not change much. We assess existing floor structure, insulation and door clearances before recommending a retrofit route.

Underfloor heating and heat pumps are well matched because both perform best at low flow temperatures. We design the loop spacing to deliver the room load at the heat pump output, which usually means closer pipe centres than a boiler-fed system.
