Underfloor heating: costs, benefits and retrofitting explained

2 min read

Short & direct

Underfloor heating provides even warmth at a low flow temperature, making it ideal for heat pumps. In new builds it costs roughly CHF 40 to 80 per m². Retrofitting in existing buildings is possible with milling or thin-layer systems and runs about CHF 80 to 150 per m² depending on the method. Exact costs depend on the build-up and floor covering.

Warm feet, free walls and barely visible technology: underfloor heating is popular – and especially efficient together with a heat pump. Here you’ll learn what realistic underfloor heating costs look like and when retrofitting pays off.

The benefits of underfloor heating

  • Even warmth throughout the room, with no cold corners.
  • Low flow temperature – making it efficient and ideal for a heat pump.
  • More space and design freedom, as no radiators are needed on the walls.
  • Little dust circulation, pleasant for allergy sufferers.

What does underfloor heating cost?

As rough guidance (excluding the floor covering):

  • New build / renovation with a new floor: around CHF 40 to 80 per m².
  • Retrofit in an existing building: about CHF 80 to 150 per m² depending on the method.

The range comes from the build-up height, the chosen system and the condition of the existing floor.

Retrofitting in existing buildings: how it works

A floor heating system can be retrofitted even without a full rebuild:

  1. Milling system: channels are milled into the existing screed – minimal build-up height, ideal for renovations.
  2. Thin-layer or dry systems: shallow build-ups that add only a few centimetres of height.

Which system fits depends on ceiling height, floor covering and heating system – we clarify that on site.

The ideal partner for a heat pump

Because underfloor heating runs at a low flow temperature, it is the perfect partner for a heat pump. If you’re planning a heating replacement anyway, it’s worth considering both together.

Tip: When changing the floor covering at the same time, the extra cost of retrofitting drops significantly – a good moment to switch.
