Underfloor heating - hydronic

The most comfortable and energy saving method to heat residential buildings

To achieve that level of comfort and energy savings, the floor heating system needs to be correctly designed, constructed and contain the right quality components.

Danfoss offers everything you need to establish a sustainable floor heating system. For every application, for heating as well as cooling, for new-build or renovation and for single family houses as well as apartment buildings.

How we can help you

Comfortable warm floors
Floor heating provides comfortable heating, as your feet are kept comfortably warm while your head is kept slightly cooler. Most people find this difference in temperature between feet and head most comfortable.

Comfort and energy savings
Equally and comfortably distributed heating makes it possible to lower the room temperature and still feel warm. For every degree the room temperature can be lowered, 5% energy is saved. In addition, floor heating does not require nearly as high supply temperatures as radiators, since floor heating has a larger surface from which the heat is emitted. Heat sources such as gas boilers run more efficiently at low temperatures, as used for floor heating.

No radiators, easy cleaning
Radiators collect dust – and cleaning around them is difficult. Floor heating is hidden under the floor and makes cleaning a breeze.

Less dust in the air
Due to the large heating surface of floor heating, less dust is whirled up. Warm radiators move a lot of heated air upwards from the grilles – and the dust travels with it.

Dry up wet floors
Most people are familiar with the problem of water on the bathroom floor. With floor heating, water evaporates quickly and the floor becomes dry and safe again.

Highlights

Floor heating should be room controlled

The desired room temperature differs from say living room to bedroom.
Floor heating is automatically reduced or turned off when the desired temperature is met which lowers your energy bill.
Therefore room control is even a legal requirement in some European countries.

Achieve perfect system balance

The Danfoss water supply system (manifolds) has pre-setting valves. They ensure that the right amount of energy (heated water) is distributed to each room.
Comfort levels are thereby reached with the least energy consumption.

Save more with temperature setback

Temperature setback during vacation, night or daytime can be scheduled or activated whenever you want.
Save 5% energy for every degree you lower the room temperature.

Control comfort by room or floor temperature

Floor heating lets you control the heating based on floor temperature or room temperature – simply set a temperature that feels comfortable!
The unique and patented infrared room thermostat as available in the CF2+ and Danfoss IconTM systems lets you control the floor surface temperature accurately.

Wireless room thermostats provide freedom to decorate

With wireless room thermostats, furniture can be placed as required without having to rewire

Adaptive learning for intelligent forecasting

If you schedule a desired temperature for eg. 06:00 in the morning, the adaptive learning will calculate when to initiate heating, in order to reach the desired temperature in time for breakfast.

AB-PM differential pressure control valves

AB-PM is a combined balancing valve providing both differential pressure control and flow limitation. The valves eliminate pressure fluctuations at full load and partial load conditions and can be equipped with an actuator to allow zone control.

Mixing shunts

Danfoss floor heating mixing shunts establish a water temperature low enough to safely be distributed through the floor heating system. It’s designed to fit the FH manifolds and mixes the warm supply temperature with colder floor heating return flow to the required floor heating supply temperature.

Panels and pipes

Danfoss floor heating panels establish the basis for a hydronic floor heating system. The Basic system contains 3 different panel models; BasicClip, BasicRail and BasicGrip. With these you can easy establish a wet (in-screed) floor heating system. For dry systems our SpeedUpTM panels are available.

Room controls

To ensure hydronic (water based) underfloor heating or cooling systems achieve the expected high level of comfort and low energy consumption, good room temperature controls are essential. They control the room or floor temperature to avoid overheating. For optimal comfort each room has it's own room thermostat.

Manifolds and actuators

Danfoss floor heating manifolds are characterized by their flexibility to establish the best suited manifold solution based on requirements. Select from all the components to construct a manifold with or without pre-setting, flow-meters, shut-off valves and air-vents that best fits your project.
