Active Closed Loop Solar Water Heater Systems
A 50/50 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 Enema or SUS 304 Stainless Steel Storage Tank With Electrical or gas Back Up
Double-walled Copper Coil heat exchangers in storage tank prevent contamination of household water.
There are three kinds of the tank: without the copper soil in the tank, with one copper coil in the tank or with double copper coils in the tank.
