Heatstorage

There are several ways to store solar heat, or heat from other sources. Water has a storage capacity of 240 MJ/m3. An average home needs 91 m3 to store half of its heat requirements (about 50 Gj).

The Specific Heat Capacity tells you how much energy is needed to raise the temperature 1 degree (F/C/K). You can find a list here.

Ground Storage

Tubes in the ground radiate and absorb heat

Horizontal : Between 0,6 meter and 1,5 meter over a large surface (200 m2)

Vertical : Integrated in the vertical poles on which the house stands

Ground Water Storage

Water is pumped around between the ground and the systems. This water may have a
flow direction. Sometimes sealed layers (between clay) are used.

Water Tank Storage

Straightforward isolated water tank. Can be very big.

Chemical Storage

Using a chemical that falls apart when heat is added, and regenerates producing heat.
