Compact Water Heaters
The "compact" systems have the solar collector and the water tank together. It is a passive system, which means that no pump or other external devices are necessary. It is a very good solution, if we do not have electricity available. The water is heated up directly by the solar collector, with almost no losses in the heat transfer from the solar panel to the water storage tank. The compact system is more simple (less components) and economical than a pumped one.
An important condition for the use of the "compact" system is that the distance between the solar water heater and the connection to the house is not too long, so it does not take too much time to get hot water in the house. Generally you can find compact equipments for households up to 5 or 6 persons. If you want solar installations for bigger houses or to combine the hot water system with the house heating, you have to go for the pumped system, which is more flexible. If the sun is shining, even in January you can get temperatures of up to 90ºC !
