2 enefits Vitodens 222-, type 2T Integral, variable speed H circulation pump HW loading cylinder The Vitodens 222- gas condensing storage combi boiler is designed specifically for heating system modernisation projects and as a replacement for older gas boilers with cylinders installed below. With output up to 35 kw, this heating centre is designed for high HW convenience. The integral loading cylinder with 1 l capacity (up to 26 kw) or 13 l capacity (35 kw) offers the HW convenience of a separate HW cylinder with approximately twice that volume. Like all Viessmann storage combi boilers, the Vitodens 222- gas condensing boiler takes up little space: width and depth correspond to standard kitchen unit dimensions. The proven MatriX cylinder burner has a wide modulation range of up to 1:7 (35 kw). Together with the Lambda Pro ontrol combustion controller, it automatically adjusts itself to varying gas qualities and ensures a constantly high standard seasonal efficiency [to IN] of 98 % (H s ) [gross cv]. Recommended applications Installation in detached and terraced houses New build (e.g. pre-fabricated houses and housing association projects): installation in utility rooms and attics Modernisation: Replacement of system boilers, floorstanding atmospheric gas boilers and oil/gas boilers with HW cylinders below. Stainless steel Inox-Radial heat exchanger for high operational reliability, a long service life and high heating output in the smallest space Modulating MatriX cylinder burner with intelligent Lambda Pro ontrol combustion controller for clean combustion and quiet operation Integral diaphragm expansion vessel igital boiler control unit enefits at a glance Standard seasonal efficiency [to IN]: up to 98 % (H s ) [gross cv]/ 19 % (H i ) [net cv] urable and efficient thanks to the Inox-Radial heat exchanger Modulating MatriX cylinder burner with a long service life thanks to stainless steel MatriX gauze resistant to high temperature loads High HW convenience through enamelled loading cylinder with 1 l capacity (35 kw: 13 l capacity) nergy efficient H circulation pump (-rated) asy to use Vitotronic control unit with plain text and graphic display The programming part of the control unit can also be fitted on a wall mounting base (accessory) Lambda Pro ontrol combustion controller for all gas types saves on fees, with inspection interval extended to 3 years Universal connection sets for individual installation flush with the wall No lateral service clearance required ssembly kit (accessory) with the dimensions and design of the appliance for the connection of one regulated and one unregulated heating circuit 2 VISMNN VITONS 222-
