Modulating boiler system
A modulating boiler system for heating a structure including a controller, a boiler operatively connected to the controller, and a thermostat operatively connected to the controller and boiler. The controller assesses a level of thermostat activity over a predetermined measuring period and adjusts the boiler in response to the level of activity to increase the boiler's efficiency.
1. A modulating boiler system, comprising:
a boiler;
a controller in operative connection with said boiler, said controller selectively controlling an input energy provided to said boiler;
a thermostat in operative connection with said controller, said thermostat communicating to said controller a proportional time period reflecting how long said thermostat is requesting heat from said boiler within a predetermined time period, and communicating to said controller a cycle frequency reflecting the number of times said thermostat is requesting heat from said boiler within said predetermined time period; and
wherein said input energy is adjusted by said controller in dependence upon said proportional time period and said cycle frequency detected by said controller.
2. The modulating boiler according to claim 1 , wherein:
a thermal output of said boiler is adjusted when said input energy is adjusted by said controller.
3. The modulating boiler according to claim 1 , wherein:
said predetermined time period is one hour.
