water not being heated in water boiler?
Problem by aosterma: h2o not becoming heated in water boiler?
Have a Hydrotherm product HC-165 very hot h2o boiler with 4 zones. Sometimes the water temperature in the
boiler drops beneath the pre-set temperature of 160F even however the distinct zones are “calling” for hot h2o.
All thermostats are set to a higher temperature than than the temperature in the home. Drinking water flows
from the boiler to the different components of the property, but its neat h2o.
I check the temperature in the boiler, and its about 60F. Confirmed all transformers connected to
the boiler are outputing 24V, NG pilot light is on, zone valves that manage drinking water movement to the various
elements of the house are open.
If I reset the circuit breaker switch for the boiler, it fixes the problem. Boiler starts up and the
water within it will get heated up. functions very good for a couple of days or weeks and the dilemma re-takes place.
A even though back I changed the thermostat that plugs into the boiler but that did not repair the difficulty.
Any idea what could be incorrect?
I bypassed the tstat (crossed the two wires heading to the tstat) and nonetheless the same outcomes. There are no security switches.
Very best solution:

The new tstat may be bad get a volt meter and see if the contact is made through the tstat. If this contact is made check the over temp safety switch and all other safeties in the circuit
The circuit breaker trips it is not big enough for the load or some load has a small internal short. Check your load requirements by checking ever thing that is on the 24 volt circuit and seeing if the total amperage is smaller than the “VA”,/24, rating of the transformer your fine there. Then look at finding a short.
Not knowing your electrical background I need to ask you if you are not confusing a circuit break for a roll out safety switch. The safety switch would be down by the burners.
