Underfloor heating or radiators?


At the beginning of the eighties the floor heating was rediscovered as a very comfortable heating possibility. Today it is a very common form of heating, but clearly has its advantages and disadvantages. A small comparison between underfloor heating and radiator heating can be found here.

comfort

Compared to radiator heating, underfloor heating clearly provides a more balanced thermal image. The heat distribution in the room is significantly better with a well-planned underfloor heating than with any radiator heating system. Rooms are always pleasantly warm and warm to the touch, which also provides a subjective feeling of well-being.

radiant heating

Like the infrared heater, the underfloor heating is radiant heating. Radiators, on the other hand, mainly heat by convection, that is, by heating the air.

Convection heaters have some proven disadvantages:

  • the heating of the room air is considered to be less energy efficient than radiant heating such as underfloor heating or wall heating (in well-insulated, airtight buildings, the difference is small)
  • the streams of warm and cold air in the room stir up dust that dries out the mucous membranes
  • Radiant heat is considered to be healthier and more pleasant, but overheated air feels rather uncomfortable

installation work

Retrofitting is very complicated in both forms of heating. In underfloor heating, however, there are very easy to install dry systems based on dry screed plates. You can even lay these systems yourself.

This results in retrofitting in many cases, a cost advantage in underfloor heating compared to the radiator heater.

When installed in new buildings, the cost always depends on the circumstances in the house. In some cases, underfloor heating can mean a higher investment, depending on the system used.

Selection of floor coverings

With radiator heaters you are completely free in the selection of flooring. In underfloor heating, however, the heat transfer values ​​of the floor coverings play an important role.

The lower the heat transfer, the less efficient the floor heating works. Not only the basic suitability for underfloor heating plays a role, but also how well the floor covering can actually conduct heat.

In the case of tiles, for example, the thickness of the tiles plays a role that should not be underestimated. The material is also decisive: For example, natural stone conducts heat almost three times better than ceramic tiles. This also affects the efficiency of the heating and the required flow temperature.

The desired floor covering has to be included in the planning of the underfloor heating. Later changes can be problematic.

Subsequent changes

Changes to the heating system are usually possible only to a very limited extent for underfloor heating systems. For radiator heaters, the possibilities of customization and enhancements are much more extensive in most cases.

Maintenance and replacement

Repair work on classic floor screeds installed in floor screed is extremely costly and time-consuming. In other systems, the replacement of pipes and the renovation of the entire heating after a few years can be very costly. For radiator heaters, the costs for maintenance and repair work are significantly lower by comparison.

Tips & Tricks

Without careful planning and dimensioning you should not install underfloor heating. Errors in dimensioning can not be corrected later. Often then expensive additional heaters are necessary because the heating power is insufficient in some areas.
