Help! I have no heat upstairs!

in Radiant Heating
Hi. My house is only 2 1/2 yrs old, practically brand new. For the past two days, I haven't had heat in the upstairs part of the house. I have radiant heating and heat with propane. I've made sure there is still propane in the tanks and the relay switch box has "zone 2" light on. I have tried to reset the water heater to no avail. There is plenty of heat downstairs and we have hot water in the sinks and showers, just no heat. The floors are freezing and the heat won't go higher than 60 degrees no matter what I set the thermostat on. Help!

    It sounds like a zone valve or actuator not opening. You may need to get a technician in there to take a look. Alot of time with radiant floor heating, there can be lots of actuators and determining which one is not opening will take some detective work.

    I'd suggest you contact a professional, because of the weather conditions. Once everything is running, then take the time to learn as much as possible about your system.

    Dave H, do you think this is something that is going to run me a lot of money, or can a plumber do it in an hour or two?

    Another possibility is that the system has lost pressure and the upper floor is air locked. Look for a pressure gauge and report back.
    Pictures of you specific system always helps.

    the pressure gauge is always very low at about 2. the manual says it should be about 10-12 but i don't think it's ever been that high.

    The type of water heater I have is a Viessmann

    @KimGonzalez -- the pressure shouldn't be that low. It is likely that the upstairs part of your system has become air locked, as @Zman suggested. Since you are not familiar with your system, and it's cold out, I really suggest finding a really good plumber (try Find a Contractor on this site, looking by state) to come by and find out what is wrong. It could be any one of several different things, but a really good plumber should be able to get you warmer in a morning. Or afternoon...
