Please help! I have a Hunter Keyboard Thermostat that came with my condo that I bought 6 years ago. I live in the Northeast and it is FREEZING in here... the thermo is reading 58 degrees. I have never had any issues with this and the prior owner left no paper trail. I have changed the batteries in both the upstairs and downstairs thermo's and everything is reading fine, but the heat is not working! I have forced hot water baseboard heaters and they are ice cold to the touch. I have reset the thermo's and it is stating that I am using USAGE as of yesterday, but still no heat. Now, I had my hot water heater replaced last spring and am wondering if this may have anything to do with it. Is there something I should be looking for, a valve or switch, to be sure the water heater is connected to the heating system? I have a gas dryer, gas stove, and hot water, all of which is working. I have turned on my oven just to heat the middle floor of my house! My poor children are buddled and sleeping with 3 blankets. Is this a serious matter, and if so, who do I report it to?

Any inkling of a suggestion would be greatly appreciated at this point!

You should have a breaker and or main switch for the whole system and for the circulating pump as well if the system has one {pump]

If there is a pump in the system, it may have airlocked when piping was disconnected to replace the water heater. Find the pump, and see if the pipe on both sides is warm. If the output side is cold, and the pump case itself is really hot, that's a sign of an airlock.
