Viessmann Water Heater

Viessmann Vitocell Indirect-Fired Water Heaters

Viessmann builds some of the most efficient hydronic equipment on the market, and its Vitocell water heaters bring that engineering to domestic hot water. These are indirect-fired tanks: instead of their own burner, they use a boiler's heated water through an internal coil to produce a large, steady supply of hot water - quietly, efficiently, and with none of the standby loss of a standalone gas heater.

Our selection centers on the Vitocell 300-V line, built from corrosion-resistant stainless steel for long life and clean-tasting water. Single-coil, indirect-fired models range from 42 up to 119 US gallons (the EVIB-42, EVIB-53, EVIB-79, and EVIB-119), sized for everything from a single-family home to a large residence with high peak demand. Heavy insulation keeps water hot between draws and holds down operating cost.

An indirect tank only performs as well as the system feeding it, so size the coil output and tank volume to your boiler's capacity and the home's peak-hour demand. Pair a Vitocell with a compatible indirect water heater setup, compare it against standard residential water heaters, or browse the full water heaters department.
