See full text

A method of increasing the efficiency of a boiler includes determining a proportional time period reflecting how long a thermostat is requesting heat from the boiler within a predetermined time period, determining a cycle frequency reflecting the number of times the thermostat is requesting heat from the boiler within the predetermined time period, and adjusting an energy input provided to the boiler in dependence upon the proportional time period and the cycle frequency.
