I have a 3-zone system, with 3 Honeywell Zone Valves V8043F wired in series and 3 thermostats. The problem is only 1 thermostat is causing the boiler to fire. The other 2 thermostats correctly open the valve, but do not fire the boiler. I measured the voltage on the 3 valves with the thermostat off and on. When the good valve activates, the voltage is 24v on the thermostat wire and 0v on the endswitch (all 3 valves go 0v on the endswitch from this). The boiler is firing at this point. When the bad valve activates, the voltage is 24v on the thermostat wire and 24v on the endswitch. The boiler does not fire. The same goes for the second valve. The bad valves do correctly open the valve. I hear the click. I even watched the microswitch get pressed down by the motor. Yet the voltage on the endswitch stays at 24v. Does this mean the two valves are broken and should be replaced?

I have hydronic radiators in my home. there is no radiatroradiators in the basement so it gets really cold and I want to add one right into my pipes that run the basement ceiling. What is a good option between 2 and 4feet long that has a thermostat . I'm guessing since its sobclose to the boiler that radiator would be very hot all the time so I need it to have self control features. Also ill include photos of the spot I want to install it at. The first closer pipe is the one that comes out of the boiler. The pipe behind it is the return pipe from the second floor. I have a weil boiler and one pump for the whole house.
