Hello, I'm building a shed with a 16 X 24 foot room that will be heated. I have installed pex in the concrete for in floor heating. I'm considering purchasing a Takagi instant hot water heater that would only be used to heat this area (closed loop, no potable water) but had a few questions:
1. The area I would like to place the Takagi heater is not inside the heated room and it gets very cold in WI. Is it ok to run anti-freeze in this water heater and what kind?
2. If I run anti-freeze, is it still acceptable to leave this water heater in a very cold room or will I have issues?
3. I'm running 3/4 IPS tubing underground from my propane tank to the heater. It's about 250 feet total distance. Is 3/4 inch line large enough to supply an instant hot water heater? The model I am getting is: Takagi T-H3M-DV-P
If it's not ok to run anti-freeze or leave this heater in a very cold room, does anyone have any suggestions? I was thinking of enclosing the heater and piping inside an insulated small room and placing a small electric heater in the room that would keep the room at 40 degrees.
Thanks for any help,
Joe
