Indirect-Fired Water Heater

The Peerless® Partner® indirect-fired water heater is an efficient and dependable option for all domestic hot water requirements. The indirect water heater utilizes a Peerless® boiler as its heat source to provide the energy necessary to heat water. The boiler fires only when energy is required to replace the heated water that is being used, or if the tank had been idle. The highly insulated tank is not vented to the outdoors and loses very little heat, even when not in use for an extended period. The water heater’s design features maximum heat transfer and resists mineral build-ups that can cause discolored and foul tasting water.

Partner® tanks are available in several sizes with storage capacities of 30 to 119 gallons to meet any application. The 30-gallon capacity Peerless® Partner® Lo-Boy is a great choice for space-limited installations!

Also, check out our Peerless® Partner® PV Tank – with a one-piece seamless design that is highly resistant to water quality variations and easy-to-operate control for extremely accurate temperature settings. Available in five sizes, the PV tank is lightweight, durable and easy-to-install!
