Cycling a boiler on and off is very inefficient because there is a pre-ignition purge and a post-ignition purge that draw heat out of the boiler with each cycle. Also, in the case of a non-modulating boiler, cycling doesn't allow the boiler to operate at part load and steady firing rate when combustion efficiencies are at their best.
