Thanks for the input. I am going to inquire further into the AWHP as the temp in the radiant floor would only be about 110 degrees
with the tempering valve so I think that water temp shouldn’t be an issue
My shop has 18ft walls with 3 overhead doors biggest being 16X20. I usually set temp at 68 degrees and leave it there.
Coldest we usually get here is - 10-15 but we have seen -24 this winter. Are you using air to water or air to air?
I am running a portage &main 160 gallon wood boiler to heat my 50X72 Shop with infloor heat and would like to know if a air to water heat pump
would work to cut down the work load for me without being to expensive to operate . The boiler works great but is getting to the end of its lifespan ...
