Hello,

I am currently remodeling a bathroom in a 40+ year old home that has hydronic baseboard heat. My question is whether it is possible and/or recommended to use Pex in the bathroom to supply radiant heat and remove the existing baseboard heater.

Thanks

Yes it is possible. The pex pipe line has a product to do this, the problem is that the baseboard heat runs at about 150 degrees F. and the bathroom floor radiant should run at about 110 degrees F. A mixing valve will have to be piped in and that is assuming that the baseboard is currently on its own circuit. Also, because the radiant heat is different than the rest of the house, it should be on its own thermostat. I don't recommend this as a handyman project for any but the best handymen. I would at least work with an HVAC tech. because it is impossible for me to predict all the problems possible with this change.
