Daniel MacEnchroeWe installed three glycol solar heating systems integrated into existing domestic hot water setups to boost efficiency and reduce gas usage. The project involved running parallel copper piping across the flat roof using specialized pipe support blocks, mounting the angled solar thermal collectors, and tying the closed loop into the indoor utility room. Inside, we connected the circulation pump station, expansion tank, and copper plumbing lines to the water storage tank.

Not a cheap system. Pending unit sizing a setup to service 1-2 people starts at 7k materials. 9+ people is 20k material. This was installed in a commercial setting with offices, showers, bathrooms. So cost returns are definitely viable. On a new build focusing on green technology and energy efficiency it's totally a great system to consider.
That’s pretty awesome, what are the costs like for install? Is the expected payback time reasonable?
Harder to tell with the current winter we're having. But with all the pipes insulated we're seeing a net gain in temp in 2/3 systems on the return line even in winter! Veissman (the manufacturer) has claims of 60% reduction in traditional power requirements on DHW.
This is really cool. Do you find they’re effective?
