Hello everyone, this is my first post although I have lurked for awhile.
I recently poured a slab in part of my pole building and I included 3 loops of 1/2" pex, 265-285 ft per loop. My slab is 24x36 so the loops were spaced 12".
Hydronic systems are fairly rare here so I had very little guidance and not really anyone to consult. I thought I had done quite a bit of research but after reading the 40 page post here about it, I wish I had found it before I bought and put together all the components I have now.
I used a calculator at supplyhouse.com and got about 30k btu. But then I see people say 2 btu/sq ft per degree of difference. With the temp being 8* outside, my slab is about 28*. To get 55*, that figures up to 46,656 btu.
I bought a 30 gallon electric HWH and set it up to run simultaneous, making 30k btu. I now realize that this was not the way to go. With that being said and my budget being spent for now, is there anything you see that I can change or setup differently for now to improve my current situation?
I plan on changing to something like a Tagaki or Noritz by next winter, but I'm stuck with what I have for now. I should also note that I don't use the shop all the time so I wanted to be able to shut everything down for possibly a couple weeks at a time. I did use glycol for this reason.
