Out of curiosity I blew all the water out of the floor pipe and measured the amount. Looks like my estimated 2-300 feet was off a fair amount. Either that or there was an air pocket somewhere. But I have one more chance to check it when I refill it with with the water antifreeze mixture. According to the numbers I have so far the floor has 150 feet of 1/2 PEX pipe. Which is actually still a little much for a floor that size. According to the info I have found on radiant floor heat you want 1 linear foot of pipe for every square foot of floor. This floor is 120 square feet… My pump is also a bit fast at 2gpm the flooring info says you want .6gpm. Haven’t been able to find ANY info on what kind of flow rate the module plates want which is why I am going by the floor radiant heat numbers………..
