Hey there everyone,
Currently thinking about intergrating a couple of solar panels into my home system. Looking for suggestions and comments.
The existing system is a hot water baseboard system with a Kerr-Saturn boiler (oil fired). Just thinking about using the solar for DHW only.
Location: Halifax, Nova Scotia
Thanks a bunch,
Kevin

Summertime Stagnation?
Looks like a great schematic. Just remember to size the solar expansion tank properly.
If you go on a two week vacation in the middle of summer, all the fluid in the collector may flash to steam. The expansion tank needs to be big enough to handle that volume without blowing the relief valve. The pressure relief valve may have to be about 75 psi.There was an error rendering this rich post.

Drawing
I am a draftsman and drew my drawing up in AutoCAD. Thanks for the replies and compliments.

Nice drawing, but....
It won't work as drawn.
You have the hydronic side connected to the potable side.
1. The DHW preheat should have an anti scald tempering valve on the preheated supply to the boiler coil for DHW.
2. The tanks return line and pump should be taken back to the boiler return.
3. You could reduce your energy consumption by 30% minimum by converting to a modcon boiler and another fuel other than oil.
I am a strong believer in insulating before you insolate...
