My condensing boiler says
No demand, the stat with new batteries is demanding 70, the house is at 57……

No error codes, got gas, got water!

Any ideas?

    Do you have a multi meter and know how to use it?

    How many zones (thermostats) do you have? Somehow, your boiler is not getting a signal to turn on.
    Take some pictures or your boiler’s piping and wiring and post them here.

    8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

    Two btu per sq ft for degree difference for a slab
