Key points about Underfloor heating
Underfloor heating distributes warmth through the floor and often works with relatively low flow temperatures. It is suitable for new buildings and, depending on the floor construction, can be retrofitted during renovations. Proper circuit design, the existing subfloor and coordination with the floor covering are essential.
Technology and planning at a glance
Floor build-up and subfloor
Planning must take account of insulation, screed, floor covering and the available build-up height. Low-profile systems may be an option in some renovations. Only an inspection of the existing conditions can determine whether they are technically suitable.
Heating circuits and room controls
Pipe spacing, circuit lengths and flow rates should match the heating demand of each room. A manifold allows individual circuits to be assigned and adjusted. Excessively long or poorly balanced circuits can prevent even heat distribution.
Checks before flooring is laid
The specified tests and documentation of the pipe routes are important before the floor structure is closed. Heating the screed and confirming readiness for floor covering are separate steps that must be coordinated with the particular construction.
How the project is prepared and carried out
- Assess floor and rooms
Clarify floor areas, insulation, build-up height and manifold location.
- Prepare the laying plan
Design heating circuits, connections, manifolds and controls to meet the heat demand.
- Install pipes and manifold
Fix the system in accordance with manufacturer instructions and document the pipe routes.
- Test and hand over
Carry out pressure testing and coordinate with subsequent trades; adjust flow rates later.
Information to include in your enquiry
To assess your project, we need a floor plan or room dimensions, details of available build-up height, existing flooring and the type of heating system. For renovations, photos of the exposed floor structure are especially useful.
TOPAL operates in Gelsenkirchen and the surrounding area. Availability at a specific location and the possible appointment date will be agreed when you enquire.
Frequently asked questions about Underfloor heating
Can underfloor heating also be installed in an older building?
Yes, in principle. Available build-up height, subfloor, insulation and required heating output are the deciding factors. A thin system is not automatically suitable for every building.
Which floor coverings are suitable?
Many tile, vinyl, laminate and parquet products can be used if their manufacturer explicitly approves them for underfloor heating. Thermal resistance and permissible surface temperatures are important.
Can underfloor heating be combined with a heat pump?
Yes. The large heat-emitting surface often permits low flow temperatures, which can help a suitably designed heat pump operate efficiently.
