The KNIGHT boiler can be installed with a Lochinvar Squire Indirect Water Heater, giving you high-efficiency space heating, plus all the hot water you need.

Squire works in tandem with KNIGHT, drawing high-temperature water from the space heating loop and circulating it through a heat exchanger inside the tank to provide domestic hot water for your home.

“Indirect” design means Squire needs no direct gas or electric heat source of its own. Because it “borrows” water from the KNIGHT boiler, Squire can provide more hot water with lower water heating costs, compared to a standard gas or electric water heater.
