Welcome! Here are the website rules, as well as some tips for using this forum.
Just bought this house. Has an older Burnham unit with a Beckett.
Three ones and heat off the coil. Boiler has been sitting quiet for a few days (switched off), so she's cold.
Turn it on. Boiler does not fire.
Zone 1 calls for heat, circulate runs, boiler does not fire.
Zone 2 and 3 work normally, call for heat, circulatory and boiler run.
Thoughts? Shouldn't the boiler run to produce hot water since it comes from the coil? It's just weird how Zones 2 and 3 work perfectly!
Appreciate any insigt.
