HAUTEC energy fence
Heat provided even on icy-cold days.

The HAUTEC energy fence, which can, e.g., be set up in the form of a garden fence, consists of absorber tubes that run on top of each other and pass each post on alternating sides.

But the decisive point is that, when compared with an air-water heat pump, the energy fence saves annual heating costs even more and does so absolutely noiselessly.

What's the reason? The energy fence absorbs solar energy and uses it to heat the brine system.

The energy fence is partially embedded in the ground in order to create a buffer possibility for the night and for extremely cold, overcast days. On sunny days, the ground is recharged by the solar gain of the energy fence.

When the sun shines, the source temperature in the case of an energy fence is therefore significantly higher than the actual outdoor temperature. Due to the solar gain, the system is much more cost-effective than an air-water heat pump, which can only use the actual outdoor temperature and thus a considerably colder source. This also occurs during the night due to the fact that the soil temperature is warmer than the outdoor air on cold days only.
