ᐅ Vacuum Storage Tank – Solar Passive House

Hello,

I am currently researching how to heat our future single-family home. Recently, I came across the term "solar house" and wanted to learn more about it...

There seem to be two alternatives that make sense to me for effectively storing solar heat:

1. The so-called earth tank - Heat is stored directly in the ground beneath the single-family home. I am unsure whether this is practical, and in case of a leak (water pipes similar to those used in underfloor heating), I would have no way to repair anything since it is located directly below the house’s slab.

2. A storage tank - Keeps the heat at a stable temperature for several weeks or months in a tank (principle similar to a thermos flask).

Maybe some of you have experience with this, or have already researched the topic.

I see a future in this technology... storing heat in summer and using it again in winter.

So long...

We had considered that as well... Helma has one in its park. The problem is that the costs outweigh the benefits.
