GREEN ACCU MAT® – The energy storage underfloor heating
The GREEN ACCU MAT® is an energy storage heating-mat by Hemstedt. It is ideal for new buildings as well as for the renovation of old buildings. It not only has the advantages of an underfloor heating but it also makes a valuable contribution to environmental protection, because it revolutionizes the idea of the night storage heating.
Energy storage heating – the night-storage heating of tomorrow!
The GREEN ACCU MAT® is layed deep into the ground and uses concrete and screed as storage medium for heat energy. Thus, during periods of excess energy (from own production or as of nocturnal wind energy), the floor is heated and then emitted again slowly over hours without reheat. The principle is quite simply the idea of a night storage heating - but in the wake of the energy revolution, for example, it uses at night excess and already existing wind energy!
Flexible and safe
The GREEN ACCU MAT® thin-bed heating mats have two independent electrical heating circuits. So if necessary, they can warm up with a doubled heating power and later warmth is maintained with half the energy of only one heating circuit. In the very rare case of an heating circuit becoming defective, the normal heating mode can still be used, thus avoiding expensive repairs.
HEM-SYSTEM® – sleeveless for even less height
All Hemstedt thin-bed heating mats are equipped with the HEM-SYSTEM®. That is, the transition between heating and cold lead conductors is sleeveless and just as slim as the remaining cable. So the laying of floor heating is even more simple and above all absolutely watertight.
For every room size
The GREEN ACCU MAT® thin-bed heating mats are available in a variety of sizes. So they provide underfloor heating to any small or large room.
A selection of controllers and thermostats adapted to every need guarantee the energy-efficient use and easy control, including the function of intelligent storage heating.
Awarded innovation - energy storage heating for the home of tomorrow!
The idea of the GREEN ACCU MAT® convinced already multiple high-profile professional juries. So this Hemstedt product was awarded with the "Industry Award" in 2014 as well as in 2016 and additional in 2015 with the "Querdenker Award"
