Our motel is having a lot of problems concerning the temperature of our rooms. Some of our baseboard radiators give off heat even though the thermostat is turned off (I can feel the hot water in the pipes). I tried to close the valves manually, but I could still feel some heat when I checked up on it a few hrs later. How would one figure out if it's a problem with the zone valves, or if it's a problem with the thermostat? Another room has the opposite problem; there is no heat going through the pipes, even with the thermostat on fulltilt. We tried to open the valves manually, but the radiator stayed cold. One side question: do zone valves really cost $150 canadian dollars? In afraid of how much its going to cost to fix this problem when the labor is costed in.

Thanks. Ill be waiting for your reply

From the kid that's trying to run a motel (apparently not so well :(

I really don't have all the needed info but it sounds like your zone valves are not fully closing and others don't open at all. You need to track down the manufacturer's name and model and check their website for specifications. Then you need to test each valve. That's all I can see with limited info. Best of luck guys.
