Super Simple, CPVC Solar Hot Water Collector
Loading...
Uploaded by GScottVideos on Nov 4, 2011
A very easy to build, inexpensive, CPVC liquid (hydronic) solar hot water collector that you can use to heat your home or for domestic hot water. This collector is significantly outperforming my pex collector in testing so far. Enjoy free heat, courtesy of the sun!

@lakecrab Good question. Why not use corrugated steel panels, such as roofing panels, place the pipes in the troughs, slightly elevated, so the sun light can strike the bottom of the pipe as well as the top. The spacing would be slightly greater, but the increase in light/heat collection would more than make up for the loss of volume.

is there a plastic covering on the front of this,or can you just walk up and touch the metal on the front,that is being used to heat up the inside,

Awesome video! What if you had zero space between the vertical tubing, would that not produce the same amount of heat but in a much smaller panel?

@ezdeezytube As long as we have a good thermal bonds between the aluminum and the CPVC risers, a good percentage of heat is transferred to the fluid. That said, the closer together the risers are, the better the performance, though that will add to the build cost.

Why would you not paint the PVC and frame flat black and leave the back panel reflective? Seems it would be more efficient.

@lakecrab Hi, light is energy. We want to capture as much of that energy as possible. The more that reflects all the way out through the glazing, the less energy and resulting heat we harvest.
