Squire

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

Armor

Water heater

ARMOR is a fully condensing commercial gas water heater. Available in eight models with inputs ranging from
150,000 to 800,000 Btu/hr, the ARMOR achieves thermal efficiencies up to 96%.

With standard tank-type water heaters, your choices are limited when it comes to matching input with storage capacity to meet “peak demand” delivery requirements. With ARMOR, you can match one or more water heaters with inputs ranging from 150,000 to 800,000 with one or more storage tanks in a wide variety of sizes. Lochinvar Lock-Temp® tanks are available to meet the need, from our 80-gallon vertical to the 5000-gallon vertical or horizontal model.

Another advantage of the ARMOR “dual component” system is lower replacement costs. Standard tank-type designs require replacement of the entire water heater. With ARMOR, you’ll save time and money by only replacing individual components as needed, such as the pump or storage tank
