Thermal Battery Storage: Difference between revisions

large thermal mass collected during the day - $100/(IBC Tote.) for 30kWhr storage using water.
Senville Aura heat pump equivalent storage for 24kBTU (7kW) is 4 hours per 250 gal tote if going from 90 to 140F. See Hot Water Calculator to get 36kWhr equvalent. For full night of 16 hours in winter - need 4 totes and 120kWhr. This is if resistive heating were used. We can 3x this with heat pumps - so the 120kWhr gets us to 40kW hr requirement. With a 14 kW PV array - thermal storage heating can be done even in winter.
