The Inventor of the ShowerPowerBooster has created a 500 litre water heat store in his home storing up to 26.4 KW/Hr of thermal heat.

During the summer a single day of sunshine can result in enough hot water which can be stored for 3 days resulting in close to 100% solar heated water for washing and bathing. During the winter 100% of the hot water in my home can be produced by a 5.5 KW wood burner although water diverted to assist central heating reduces the 3 days of storage by choice in wanting more central heating.

Without the wood burner any home owner including myself could buy free electricity during periods of high wind and/or a cheap to zero rate electricity during the night stare the same 26.4 KW/hr.

The V1 pump already on sold is required to modify heat gradients in any existing gravity or hot tank.
