1. A controller system for controlling a plurality of parallel central heating boilers comprising;

  • a boiler selection means;

    said boilers selection means including a fuel consumption profile for at least some of the boilers and boiler combinations capable of satisfying a heating load at a given outdoor air temperature;

    said fuel consumption profile comparing the relative efficiency of each boiler or boiler combination in terms of fuel use per degree unit time as a function of degree unit time for each said boiler or boiler combination;

    a boiler controller for placing each boiler or boiler combination on line in response to a signal from said boiler selection means;

    outdoor air temperature sensing means in communication with said boiler selection means;

    means to compare each fuel consumption profile to determine which boiler or boiler combination consumes the least amount of fuel at the sensed outdoor temperature and to signal said boiler selection means to select the determined boiler combination;

    whereby the boiler or boiler combination which consumes the lowest amount of fuel at the sensed outdoor air temperatures are operated.
