    It sounds like the T&P valve is leaking, I would check the water pressure in your house and check the Temperature setting, if both are OK then the T&P valve is failed and needs to be replaced, check the water pressure and the Temperature fist, Good luck.

    You might check out a expansion tank also. Cheers. Tom

    Agree with afaroo and Tom (system needs an expansion tank for sure if you don't have one.. I would guess that you are running low pressure (like around 12psi) through the floor heating system, yes? How hot is the water. What type of floor, concrete, wood, etc? Temp shouldn't be above 140 for concrete (we usually run our systems at 130 in concrete) and never above 160 for wood floors (140 is preferable).

    So, if your pressure is what it should be, and your temps are within range, it sure sounds like a faulty temp/ pressure relief valve.
