How would you wire in the aquastat to control your slab ?
Huff
My aquastat is meant to tie onto piping. So, I was thinking, in the slab situation, of using it to kick on/off the pump at a certain temp. Because the shed slabs are heating up the foundation---I have a shallow foundation system which relies on the heat from the building to keep it from heaving--more than to provide heat in a workspace, I have the manifold plumbed to the return line of the boiler. This is also out of practical necessity. I was thinking that the aquastat could read the temp on the feeder line to the manifold and only kick the pump on when the return line was over 150º, say. This would keep the slabs from stealing & diluting heat from the main system, and as they only need to be kept above freezing plus a bit unless I am doing a project or something out there, in which case the I would have the boiler going anyway.
At least this is my theory on a way to use the aquastat "outside the box"....however, I have a spare wall timer.....that seems like it could work really well to turn the slab circ on and off too......say 15 min every hour for 12 hours?
