Waterborne underfloor heating is a low-temperature heating system

Waterborne underfloor heating is a complete heating system that often replaces conventional wall-mounted radiators. It is a low-temperature system that fits well together with energy-saving heat sources such as a heat pump, pellet boiler and solar heating or a combination of these.

Water-borne underfloor heating warms the entire room in a pleasant way. The direct reason why underfloor heating is experienced so pleasantly is that heat is generated at a low temperature distributed over a large surface. With this type of radiant heat, the heat is distributed more evenly in the room and the warmer air stays at the feet, while there is slightly cooler air at head height.


By quickly heating the air that comes down on the floor, underfloor heating in many cases prevents frostbite. Underfloor heating produces less air movement than radiators and therefore releases less dust. In addition, you avoid the dust-collecting radiators on the wall. Underfloor heating works well under all types of floors.


Underfloor heating and energy

With waterborne underfloor heating, you save energy. Because the heat in the room is distributed more evenly compared to other heating systems, the average temperature in the heating system can be kept lower than with, for example, radiators. However, the energy use is affected by the home's insulation, the indoor temperature and how much of the season you have the system on. In larger premises such as warehouses and sports halls, the average temperature can be significantly lowered and thus provide the opportunity for energy savings.


As the underfloor heating system is a low temperature system, all losses in the supply line pipes are reduced. Heat pumps and solar collectors become significantly more efficient in these systems than in heating systems with higher water temperatures. A heat pump can e.g. consume 30% less energy when the water temperature is reduced from 55°C (radiators) to 35°C (floor heating).


The history of underfloor heating

Underfloor heating is actually an old invention and its history began already 6000 years ago. And it is very possible that it was Swedish Stone Age people who invented underfloor heating. In Voullerim in northern Sweden, remains from the Stone Age have been found where a primitive form of underfloor heating can be demonstrated. At that time, flue gases from the fireplaces were transported into the ground. The ground was heated and in that way the Stone Age families could stay a little warmer at night. A primitive, but incredibly brilliant idea!


During the 1920s, the British and French developed various underfloor heating systems that are reminiscent of today's waterborne underfloor heating systems. In Sweden, underfloor heating had its breakthrough in the 1980s.


Today, underfloor heating is an established heat distribution system with many technical and operating economic advantages.
