The Vitodens 111-W is a particularly space saving, wall mounted gas condensing storage combi boiler for situations where high DHW convenience is required.
The heat cell comprises the proven stainless steel Inox-Radial heat exchanger, the modulating MatriX-Plus gas burner and the Lambda Pro Control automatic combustion controller.
The integral 46 l stainless steel loading cylinder offers the same DHW convenience as a separate 150 l DHW cylinder with internal indirect coil. DHW is available immediately and constantly at the required temperature, even simultaneously at different draw-off points.
In addition to the loading cylinder, all the most important system components, such as the heating water expansion vessel, pumps and safety valves, are integrated and fully fitted.
All this with a total weight of max. 68 kg and in a casing that fits into a standard 600mm wide kitchen unit space.
Recommended applications:
- Installation in detached and terraced houses.
- New build (e.g. prefabricated houses and developer projects): Installation in utility rooms and attics.
- Modernisation: Replacement of gas system boilers, floorstanding atmospheric gas boilers and oil/gas boilers with DHW cylinders installed below.
- Replacement of boilers in various types of systems, including those with several heating circuits and underfloor heating.
Benefits at a glance:
- Seasonal central heating energy efficiency ηS up to 94 % (label A).
