About a month back I noticed the heat (I have forced hot water) wasn't being produced on one floor, so I checked the zone regulators and noticed one was most likely no longer working. I'm no plumber or electrician, but I tried to employ some logic and felt the electric power head was cold as well - and the copper piping that followed it was also cold - I figured this was indication enough that there was no flow from that unit. I replaced the power head and turned up the thermostat - the furnace kicked in and I felt hot air radiating from the base boards.
These are all three regulators - look at that dust!
The green part is the electric power head

For now, if this is the problem, you could possibly swap the power head with a different zone to generate heat. Again, I'm no electrician or plumber, but just some idiot with two hands and a curious nature. There's also a level on the power head that opens the valve - it's normally set to auto, but you could attempt to lift that lever and see if any heat is produced.
