<span>Hello, we will be filling our garage floor heating system soon (it is a closed system dedicated to a 40x40 detached garage). </span><span>Could anyone provide some insight as to how to determine the fluid capacity of a system with approaximately 1700 feet of 1/2" pex? I ask as we will be using </span><span>the appropriate antifreeze at 50% (a product such as DOWTHERM) and I need to determine how much to buy for the mixing. </span><span> We are trying to find a supplier for the product in our area and I'd like to go in with some idea of quantity needed.</span> <span>Thanks</span> <span>Chris</span>

.92G/100'
Wirsbo specifications indicate that 1/2" nominal inside diameter tubing contains .92 gallons per 100 feet of tubing.0 -
50% is a little much.
Unless you are in northern Alaska or Northern Canada, 50% might be too much.
A 30% mix is sufficient for our climate here in Maine and keeps from putting too much strain on the circulator.
Cattledog's information is dead on.0 -
Thanks!
I'm in Southern Ontario Canada, similar climate to most northern states.
