One of the latest inventions concerning solar energy is the solar pool heater. Pushing the envelope further, solar home heating can also be done. This was basically inspired by the experience of getting burnt once your skin gets in contact with water (primarily from hose) that has been sitting out on the sun for too long. This is called passive solar water heating.
Before the beginning of the 21st century, states like Los Angeles and Florida have already taken advantage of passive solar hot water systems. There were a number of sytems using solar water heating that are located in the mentioned states' roof tops.
Nowadays, the solar water heater is referred to as PSWH, Bread Box and Batch Heater. However, the technical term for this contraption is the Integrated Collector and Storage System or ICS for short.
Usually starting with 40 gallons of water in a lined tank made of glass, these systems come in the form of electric water heaters. With its temperature engine, the owner must only set it under the sun and it's good to go. It is also painted black because studies show that dark colors attract heat more than light colors.
Make sure that the box had been well insulated in order to prevent the loss of energy. Also, the insulation amount is dependent on the climate. Ideally, the box has the measurements of either 2 X 4s or 2 X6s. Fiberglass insulation is also often installed. For aesthetic purposes, the owner may choose to have his box painted in such a way that would match it to the area where it is placed.
