How often should the boiler limit switch be reached?
We have a boiler/radiator setup and the boiler is likely from the mid eighties. The only electrical pieces are the aquastat and the burner valve.
On long set-back recoveries (every morning), the boiler will reach its 180F limit in about an hour of straight running and cuts off the 110V to the transformer. This in turn powers off the burner and keeps the circulator running. It also powers off the thermostat which is annoying. The radiators are free of air and the circulator runs fine.
Is there a solution to this?
