Hello all-
Just a thought, but what if (assuming that you use ground water) a person were to run water first through your radiant floor tubing then to your water heater. Wouldn't this effectively preheat the water while at the same time remove heat from your thermal mass and hence your house?
This system could also be used if you harvested rain water by either:
a) storing your water underground or
b) running tubing from your storage underground and then through your floors
It would probably work best if you had a maximum of tubing in your house, or enough so that the volume of the tubing was similar to the volume of the water heater as to allow for maximum heat transfer.
Just wondering what you all think.
