Polar Furnace / New to Polar G2
« on: April 06, 2017, 01:17:24 PM »
Hi
I am building a home this spring and will be installing a Polar G2. I will have it going into the house for forced air and domestic hot water. I will also be putting a run into my detached garage with in floor heating.

I am having a hard time finding an installer in my area so I will be doing it myself. I'm not to concerned with putting the hot water side arm on or the water to air exchanger in the furnace. I will have my plumber and HVAC guys do that part when everything is being installed. The trouble I am having is determining what valves, manifolds, etc I will need to do it right the first time. I have the diagrams from the Polar web site but some of there lingo is still unclear to me at this point.

I believe the G2 has built in capabilities for two pumps right on the unit. I would assume I can run one to my garage and the other to the house. When I get inside is where the lack of information kicks in. I'm not sure how the system knows how to send heat to which unit/area. I see mixing valves, motorized mixing valves, circulators, thermostatic mixing valves, thermostatic radiator valves, diverting valves, diaphragm expansion tanks etc.

Want it right but don't want overkill.

I was hoping someone would have experience with this and be able to lend some guidance.

Thanks
Dave
