Dear Readers,
My Burnham MPO boiler was installed in August. I've an indirect water
heater attached as well. The domestic hot water works fine and heats
up on demand as expected. Now that heating season has begun, I find
hydronic system with very very weak heat output. The new circulator
is running fine. The manual says there is a 15degree differential
between the "high limit setting" and a call for boiler ignition. I
see the high limit is set at 200F. I raise the thermostat to call for
heat, but I watch the boiler thermometer go down to under 90deg F and
never come on. The only way it does come on is if I run the hot water
too.
Any ideas or suggestions on what is wrong would be appreciated.
Regards,
Anthony Falcone

I bled everything more than once. Don't think that's the case as I
hear the circulator running smoothly with water.
