We also have a new type which have copper coil in the water tank, when the water pass through the copper coil, it is warmed by the hot water in the tank. It is also pressured. Heat exchanger inside the tank which provides more than 1.5m
2 of heat transfer area. When water flows though the coil it absorbs heat from the water inside the solar collector tank. The solar collector tank is therefore a thermal store. One advantage of this system is that almost no water is introduced into the tank (apart from occasional topping up), so corrosion and scale buildup are almost totally eliminated. Tanks are designed for low to medium pressure applications using gravity feed tank or pressure reduction valve. Direct connection to mains pressure water supply is not permitted. Please check your local building/plumbing regulations regarding the installation of water tanks. |
