Are modulating burners really worthwhile? - Heating

The boiler will still lose 30,000 Btuh because the boiler jacket does not know that the boiler is at low fire. It just knows that the boiler is warm. If our burner is a 3 to 1 turndown and drops to a low fire setting of 330,000 Btuh, that 30,000 Btuh loss just Tripled our jacket loss percentage to 9%, dropping the efficiency of our boiler from
