under floor hydronic heat
Hello,
I would like to add some extra heat to the rooms over a crawl space approx 500square feet. The bedrooms and hallway(350SF) are hardwood and the laundry and 1/2 bath (150SF)are tile. The thermostat is in a hallway and is set at 70F.
The crawlspace walls are insulated. The rooms off of the hall are usually 65-67 when the hall is 70. The wood floors are 62-65 and the tile is COLD.
I have baseboard heat with the water set at 180F.
I would like to add a zone to heat the floors from below. I understand if I attach the PEX to the underside of the floor I will need to cool the water to 120ish with a mixing valve so I dont damage the wood floor.
I am thinking of running the PEX on the bottom of the floor joist so I dont have to fight looping it around and wont have to add a mixing valve and hopefully I can keep the temp at 180 with no damage to the floors.
Any ideas??
Thanks
