Water heater

Hydronic buffer tanks are utilized to provide thermal storage volume when the system demand is less than the lowest firing rate of the boiler. This occurs most often when there are “micro” zones in the distribution system whose demand is below the minimum firing rate of the boiler. Under these conditions the boiler fires at its minimum rate, which is more energy than can be absorbed by the distribution system, and shuts off because of high return temperatures before the “micro” zone’s call for heat is satisfied. The boiler system continues to receive a call for heat and fires again. The “micro” zone cannot absorb all the energy produced by the boiler, and again the boiler shuts off because of high return temperatures. With the volume provided by the tank the additional energy not utilized by the “micro” zone can be stored in the buffer tank and used when there are additional heating demands
