•This is a new patented device that retrofits to any simple tank to create a low-cost and efficient heat store
•The device stores energy at night using surplus off-peak cheap electricity to allow multiple showers and baths during the day without using extra electricity or gas.
•It stores energy on days when there is an abundance of wind or solar for later days later when there is no wind or sun.
•It replaces gas for heating water and has a great potential to centrally heat homes using no gas thus saving you the standing charge.
•Unlike heat pumps it is as efficient on any cold night as it is on any night.
•It is very cheap, very effective, very easy to install, whisper quiet, and in 20% of UK homes it is a simple retrofit.
