solar water heaters (pre-heated)

Description

Features: Thermosiphon solar collectors provide Mains Pressure pre-heating via a high efficiency copper coil heat exchanger installed within the solar collector xxxxx way in which the Mains Pressure solar collector heats water is the same as the non pressure solar collector. Instead of using the water in the tank directly, as the Non pressure does, the type uses a ****0 meters copper coil heat exchanger inside the tank which provides more than 1.2m? of heatfor thermal storage. One advantage of this system is that almost no wateris introduced into the tank (apart from occasional topping up), so corrosionand scale buildup are almost totally eliminated. Tanks are designed for lowto medium pressure applications, using a gravity feed tank or pressurereduction valve. Direct connection to Mains Pressure water supply is notpermitted. Please check your local building / plumbing regulations regarding the installation of water tanks. .
