Question about our products


Use walls and floors as energy storage

The classic night storage heating is somewhat discredited. But in the context of the energy revolution and the increasing availability of solar or wind energy, the storage heaters are regaining importance. Because here, excess energy can be stored useful in the form of heat and reemitted over several hours, without the addition of more energy. 

Ideal for already existing real estates

Not every existing property can be transformed into a low-energy house in the course of restoration. But with the concrete heating mats of Hemstedt, cheap energy from overnight rates or excess energy from power spikes, for example generated by wind energy, can be stored and used. 

Save energy - conserve resources

So not only heating costs can be saved, it is also a meaningful contribution to the energy revolution. Because thanks to storage heaters, for example, wind energy can be stored in the early morning in the form of heat. When the electric supply networks are busy with the beginning of the day, energy for heating is no longer needed. 

Wise control and regulation

Hemstedt concrete heating mats can be used as storage heaters much better, if an intelligent control is used that controls all appliances in the household, including the storage heater and matches them if necessary with availability. Corresponding intelligent controls can be found here: controller and thermostats
