A control system is provided for a modulated heating system including a plurality of modulating water heaters, which may be modulating boilers. A deadband control scheme provides for reduced cycling of the modulating heater when total system heat demand falls between the maximum output of one heater and the sum of the maximum output of that one point and the minimum firing point of the next subsequent heater. Condensation of flue gas products is prevented by monitoring flue exhaust temperature for each heater and controlling the modulation of each heater...


1. A method of controlling a modulating water heater, comprising: (a) monitoring an exhaust gas outlet temperature from the heater; and(b) maintaining a heat output of the heater at or above a minimum level sufficient to maintain the exhaust gas outlet temperature above an exhaust gas outlet temperature setpoint, wherein the exhaust gas includes water vapor and the exhaust gas outlet temperature setpoint is above a condensation temperature of the water vapor in the exhaust gas. 2. The method of claim 1, wherein: in step (b), the minimum level is greater ...
