I live in a condo and have floor board hot water heating systems throughout. The system is hooked up to a heat only thermostat and is 24volts. I am having problems with the system and could use some advice. I've checked for power at every point in the system and I have appropriate power everywhere. The problem is that the system does not seem to be responsive. What I mean is that the system seems to be heating but at a very low capacity. I turn up the thermostat and it doesn't heat past a certain temp (about 70 degrees Fahrenheit). I assumed that the problem was the zone valve head so i ordered a new one and proceeded to change it, following the directions precisely. The pipes for both the input and output are extremely hot (i can only hold them for about 10 seconds before i need to let go). Also, i use to hear the valve or something related to it click every half minute or so. Now it doesn't make a noise what so ever. Any advice would be great.
Thanks, Raymond
