How an order proceeds

1. Inspection and calculation, free of charge

We will arrive, measure the rooms, determine floor construction heights, assess the subfloor condition and identify the heat source. Based on the floor plan and insulation, we calculate room-by-room heat loss. For new builds, the project documentation is sufficient; for renovations, we inspect beneath the existing flooring.

2. Floor build-up design and budget

You will receive circuit diagrams with spacing, manifold location, control design and an itemised estimate. Nothing is hidden under "other work". If anything changes on site, we resolve it in advance and in writing.

3. Preparation of the substrate and insulation

The substrate must be level, dry and clean. We will install thermal and impact sound insulation according to the floor type, perimeter expansion tape and system board. For dry construction, distribution boards with slats are used.

4. Laying and pressure test

Pipes or mats according to the drawings, each room with its own circuit, connected to the manifold. Before pouring, the system is pressurised and left under pressure. You will receive a protocol; no pouring takes place without it.

5. Screeding and curing

Anhydrite or cement screed, thickness according to the project. The screed must cure; for poured mixes this is usually weeks. During curing the system remains under pressure.

6. Heating test

Controlled temperature ramp-up according to the screed manufacturer's specifications, residual moisture measurement and a protocol for the floor covering installer. This step is most often skipped, resulting in cracked tiles.

7. Control and handover

We will set the thermostats, zoning and the source's eutectic curve, and balance the flows. We will explain the controls and hand over the documentation: circuit drawings, protocols, manuals and warranty certificates.

What to prepare

• Floor plan with room dimensions; for new builds, project documentation including floor layer compositions.
• Information on the heat source (heat pump, boiler, electric) and the location of the utility room.
• Planned floor coverings by room.
• For renovations, please provide a photo of the existing floor and an estimate of the available height.
