Weil-mclain 672619207684 Aqua Plus Indirect-fired Water Heater 105 Gallon

Product Description

The Weil-McLain 672619207684 is a 105-gallon residential indirect-fired water heater from the Aqua Plus collection. It is built for homes and light commercial settings that need a large, reliable hot water supply. Indirect-fired water heaters work by pulling heat from a boiler through a heat exchanger inside the tank. This means no internal burner is required. The system uses your existing boiler as the heat source, which often results in lower operating costs and fewer components to maintain.

The tank body and heat exchanger are both constructed from 316L stainless steel. This grade of stainless steel offers strong resistance to corrosion, pitting, and crevice damage. The heat exchanger measures 1 inch in diameter and runs through the tank to transfer heat efficiently from the boiler water to the domestic water supply. The tank is fully passivated, meaning it has been chemically treated to maximize corrosion resistance. This eliminates the need for a sacrificial anode rod, which reduces long-term maintenance requirements for the homeowner or building manager.

A digital thermostat provides precise temperature control for consistent hot water delivery. The unit includes a temperature and pressure relief valve for safe operation. Side connections make plumbing connections straightforward and keep the installation neat. Adjustable feet allow the unit to sit level even on uneven mechanical room floors. The maximum working pressure is 150 psi, and the tank stands 59-3/4 inches tall with a 30-inch diameter. It weighs 238 pounds. The first hour rating of 448 gallons means this unit can meet high-demand morning peak loads in larger households or multi-family settings. The Aqua Plus line is AHRI Certified under reference number 10358740, confirming independently verified performance ratings.
