On-demand water heater w/ radiant slab
I’m a big fan of stained and sealed concrete floors. As such, besides its other qualities, I like using radiant heating with them whenever possible. I have seen on-demand hot water systems used in conjunction with heated slabs and heard they achieved a high level of efficiency. However, I can’t seem to find too much on how to appropriately determine the system requirements; any comments/ suggestions would be great.
