Product Description Detailed Product Description A *0/*0 propylene glycol and water mixture from the collectors through a coil of pipe in the solar tank, and then is pumped back through the collectors. The potable water is warmed by heat transfer through contact with the pipe. These systems are pretty much the only choice in very cold climates. When there is not enough energy for sun, an electrical or gas back up element will be automatically switched on by controller. Feature: Simple Installation, No Maintenance, Effective operation Easy Retrofitting To Existing systems Suitable for single and multiple solar heating Application systems, Preferred option for extremely cold areas and questionable water quality. Incoming potable water is routed to the solar storage tank Porcelain Enemal or SUS**6 Stainless Stee Storage Tank With Electrical or gas Back Up Double-walled Copper Coil heat exchangers in storage tank prevent contamination of household water. Operation The controller (*8) will switch on the pump when the temperature at the collector sensor TC is higher than the return temperature TR by at least the pre selected (delta T) amount. The pump circulates a heat transfer liquid around the loop. Heat from the collector is transferred to the domestic water through the heat exchange coil in the tank. With the pump running, if delta T is not met, the pump will switch odd. When a present tank temperature is reached at Tmax, the controller switches off the pump. The check valve (non-return valve) prevents heat from the tank facing towards the collectors should the tank be warmer (e. G. At night).
