The Vitodens 222-F storage combi-boiler combines the benefits of the Vitodens 222-F with the high DHW convenience of a separate DHW tank. With the MatriX gas burner and the stainless steel Inox-Radial heat exchanger, the Vitodens 222-F offers top technology for many years of energy efficiency and high heating and DHW convenience. The Lambda Pro Control combustion controller and the 3-speed high efficiency circulation pump, ensure permanently high efficiency, reliable operation and low power consumption.
The Vitodens 222-F is equipped with integral sensor technology that enables operation without minimum flow rate. The integral stainless steel 26.5 USG primary storage tank offers the same DHW convenience as a separate DHW cylinder approximately twice the size.
