Abstract:
1. A method of heating a building comprising the steps of: determining a mode of operation based on the time of day; operating in a first mode during a first portion of the day; operating in a second mode during a second portion of the day; wherein said first portion of the day is that period of the day preceding a peak load demand time, and said second portion of the day is the peak load demand time period of the day; and transmitting a signal to a first valve, said signal indicative of a desired rate of heat input based on increasing a water loop temperature to a high limit when operating in said first mode to store heat in the water loop during the first portion of the day, and said signal indicative of a desired rate of heat source input when operating in said second mode, wherein the desired rate of heat source input is constant in the second mode to reduce peak demand for the heat source input during the second portion of the day.
