The most important things in brief

Comfort: Underfloor heating ensures even and pleasant warmth throughout the room.

Energy efficiency: Low flow temperatures save heating costs and are ideal for renewable energies.

Space-saving: No need for radiators, which offers more design flexibility.

How does underfloor heating work?

Underfloor heating distributes heat via heating pipes or heating mats laid in the floor.

• Heat source: Warm water is passed through the pipes via a heat generator (e.g. heat pump or gas heater).
• Heat emission: The stored heat rises evenly and warms the room from below.
• Control: Thermostats and mixers control the temperature precisely.

Types of underfloor heating

wet system

Features: Heating pipes are laid in screed and covered with concrete.

Advantages: High heat storage, ideal for new buildings.

drying system

Features: Heating pipes are inserted into special panels, no screed required.

Advantages: Quick installation, ideal for renovations.

Important components

fixed value control sets

Features: Keeps the flow temperature constant, ideal for existing heating systems.

Advantages: Cost-effective control for underfloor heating in combination with radiators.

advantages and disadvantages

Advantages: Pleasant radiant heat, space-saving, energy efficient.

Disadvantages: Higher installation costs, slower response time than radiators.

possible uses

Ideal for new buildings, renovated old buildings and combinations with heat pumps or solar thermal systems.
