Running PEX in-floor in addition to baseboard
I’m building a new wood frame home with hot water baseboard heating in climate zone 6. The bathroom will have tile floors and I was thinking of using some electric resistance heat under the tile along with a baseboard hot water radiator in the bathroom. These electric systems are not inexpensive to install or operate so I am now considering simply running loops of Pex (the supply line to the bathroom radiator) between the joists to keep the tiles warm before the water in the line gets to the baseboard radiator.
The goal is to keep the chill out of the tile while still allowing the radiator to actually heat the room.
The PEX could be stapled directly to the subfloor or installed with typical aluminum reflectors as done w in-floor heating.
The bathroom is on a dedicated zone for that space only.
Any problems with this?
