Weather compensation
Intelligent weather compensation
The Vitodens 100-W Open vent can even operate in weather compensated mode without incurring a costly heating system modification, all that is needed is a simple upgrade.
Weather compensation acts like an auto-pilot as it detects outside temperature changes and automatically adjusts the flow temperature of the boiler, achieving gas savings of up to 12% in the process.
Compact dimensions
With a depth of only 285 mm (340 mm on the 32 kW model) the compact Vitodens 100-W Open vent boiler is perfectly suited for integration into standard kitchen cupboards.
It can also be used in a vast number of other applications where there is only limited space available.
Versatile system solutions
Whilst being specifically designed for open vent heating systems, the Vitodens 100-W heat only is suitable for sealed systems using an additional expansion vessel safety valve.
