Recommendations on wall hung lp water heater for radiant.
Built a new shop 30x40 x16' high.one 36"walkthrough, one 16x14 insluated overhead door. Two inches of closed cell goam walls,and roof. Two inches of styrofoam underslab.1260 feet of barrier pex going in the concrete 12" layout.
Now I am looking at a wallhung water heater. Seems most of the smaller btu ones are plumbed 1/2 inch in and out. I am thinking maybe going with the takagi jr.
Not sure what pump I will be using as of yet,but most likely a three speed of some sort.
Thanks in advance. Eric in central Indiana
