My house is slab on grade and I have pex running in it. I'm not sure of the spacing or layout, it was done before I bought the house. Based on my neighbors which was built by same contractor it was done correctly. As far as I know there is 2" foam under the whole house.
The trouble I have is to be honest I'm not very satified with the whole system. One of the big reasons I bought the house was for the slab heat. I had always been told that it was so effeicent you could heat for cheap compared to any other type of heat. And it's so comfortable you can keep the house colder.
I never found that the case. The first year I was in the house I saw $150-$175 gas bills each month. To compare my neighbor a few houses down has a forced air system and he told me he has never seen over $100/month gas bill.
ANYHOW...
After that first year I got a wood stove and I have not used the floor heat very much other than in the garage.
A few weeks ago I rented out a spare room. Before they moved in, I just left the door closed to that room and kept the thermostat set to 50-55*. The thermostat controls the heat to that room and also one other bedroom.
Since the moved in we set the T Stat to 68*, which is a reasonable temp. I don't expect them to be cold because I am too cheap to run the boiler you know? As long as the door is left open it will stay 65*-70* in there, all depending on how cold it is outside. Oh course I don't expect the door to stay open all the time either.
It seems when there is a call for heat the boiler runs near constantly to warm the room. I am seeing around 130* input to the pex and 100-110* return. The temp of the floor is about 75* so I don't understand why it would be hard to achieve 68*? I even went ahead and throttled back the water flow to the other bedroom since I have no reason to heat that room (it's used for storage and some gym equiptment)
I'm almost wondering if maybe because I am using the wood stove when the door is open the temp is fine so the slab cools. Then close the door for the night and the slab has to be rewarmed?
His room is running at 2gpm and the other room is at .75gpm.
Any thoughts?
