Weil-McLain Steam boiler - hydronic loop stopped working
We have a single pipe steam system. Works like a charm.
Unfortunately though the hydronic loop for our extension that is on a different thermostat
I can feel the pump starting when the thermostat is on 'heat'. But there is no warm water circulating
and the boiler does not seem to be on.
I feel the pump is running a bit hot. Like there is no water in it. But that might just be me projecting.
Entire system is about 4 years old.
Any pointers and / or suggestions would be much appreciated.
