Heat Storage (HS)
From the Design Strategy example, it was decided that 2400kwh/day was to be collected.
For modularity and ease of construction, it is suggested here that a 1m³ heat storage block size is suitable for easy expansion by joining the pipes that pass through the blocks together outside of each block.
In App. Diagram 7 the Heat Transfer Buffer (HTB7) shows an example of how heat transfer blocks can be constructed in order to collect heat that is of two different temperature and storing or moving them both on at a new temperature that is slightly lower than the lowest input temperature.
Interestingly, that is very similar to how mixing two different salts with different melting points will produce a new compound with a lower melting point.
An example of how it can be built physically is shown in Boiler with Heat Exchanger.
Storing heat for a very long time is not really practical, because sooner or later the heat from the higher temperature will, over time, leak through any insulation to the lower temperature.
Design your own heat storage and save money.
