Using residual solar electricity to heat a common 240v oil radiator.

Thermal Energy Storage – TES. Sand is cheap, readily available and can be used to store thermal energy at much higher temperatures upto 1000°c, compared to water limited at 100°c turning to steam. With sand slowly releasing that heat, as a thermal mass.

A high humidity environment, such as near the coast, or in high rainfall regions, often needs low cost, simple, to silent or passive measures to keep humidity reduced in the home for comfort and health, discouraging mould.

Solar hot water: is more efficient than heating water electrically. A large well insulated hot water storage tank is also one of the best storage batteries for heat/cold. This could be coupled with a thermal Sand Battery for longer heat storage/transfer.
