A surface heating system is the ideal low temperature heating system. Its temperature profile is closest to ideal heating. What makes ClimaLevel® special is its extremely large heat exchanging surface, which is provided by the floor through the hollow space below it. Due to the physical relationship “the larger the heating surface, the lower the heating medium temperature†ClimaLevel® enjoys the position of being popular with operators of heat pumps or solar heating systems. The ClimaLevel® heating pipe emits its heat into the surrounding soil as well as into the air streams flowing passing by. The system can, of course, be coupled with a system for heat recovery.
