A Better Way to Achieve 97% Thermal Efficiency
Fully Modulating with
5:1 Turndown
ARMOR features advanced Negative Regulation (Neg/Reg) sealed
combustion technology, permitting fan speed to constantly adjust the
volume of fuel and air entering the burner. This ensures that ARMOR can
safely and reliably operate with supply gas pressure as low as 4 inches
water column.
ARMOR is equipped with fully modulating combustion with 5:1 turndown. This means ARMOR can fire as low as 20% of maximum input
when water heating demand is lowest, and increase the firing rate up to 100% as demand increases. The result is better overall efficiency
and less cycling, compared to all other tank-type units which are “on-off,” which means they can only fire at 100% of maximum input.
Stainless Steel Condensing Heat Exchanger
The ARMOR’s stainless steel heat exchanger is built to ASME Section IV requirements. Its design provides superior resistance to
corrosion caused by condensation from low entering water temperatures. Traditional commercial water heaters will fail early with low
entering water temperatures; however, with the ARMOR the lower the supply water temperature the more efficiently it performs
throughout the life of the 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 97%.
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.

Sidewall Vent Termination
ARMOR offers 7 venting options and tremendous flexibility for
placement of units within the building, because it permits direct-
vent air intake and exhaust runs up to 100 equivalent feet using
either PVC, CPVC, Polypropylene or AL29-4C stainless steel vent
pipe. Intake and exhaust runs can terminate horizontally
through a sidewall or vertically through the roof.
