I'm putting in some work building the hydronic heating system for my garage. I have nearly all the parts for the system and have dry-fit them together. Now I'm starting to sweat all the parts and solder them up! Most of these parts are from the Menards home improvement store.
The heater is a 7kW electric micro-boiler. That will be on its own 30A/240V circuit. The pumps are cast-iron fractional horsepower and run on 120V.
At the moment, the garage is running on temporary power (extension cord from the house) and has no insulation or doors. I apologize in advance for the sound! It's echo-y in there, and I can't keep the traffic noise out yet!
