Ice storage in prefabricated house (new construction) - provider

Hello everyone, we are planning a new build with a prefabricated house provider in NRW. We definitely want to install an ice storage heating system. The house should be designed in a very modern style (Bauhaus style). Which providers currently support this?

How do you come to want to install something like that in every case?

Presumably, you have read an article that ice storage tanks are the future? ;)

Hello, I also thought for a long time about installing an ice storage tank, but in the end, it is technically too complex.

If your property is large enough, find out about [Ringgrabenkollektoren]. That is a much better heat or cooling source. And the system technology cannot be much simpler.

These ring trench collectors were offered to us by Laux last year; they seem to have good experience with them. They build in Saarland, I believe they also do prefabricated construction (but also solid construction).

It would be important to know how you come up with the idea – ice storage might make sense for very specific cases, but a normal single-family house with modern insulation most likely does not fall into that category.

If cooling is the main reason, then other alternatives are better: air conditioning in the first place, and to a lesser extent passive cooling via heat pump. For the latter, a deep borehole is slightly preferable, but a ring trench collector works almost just as well (especially for heating). A ring trench collector is usually exempt from approval and more cost-effective (especially if done as DIY, otherwise not necessarily), but it also has disadvantages – depending on the design, the property will be heavily excavated, including temporary storage of earth masses, with corresponding impact on the property area (which then has to be "repaired"). We have a ring trench collector.
