Compact enough to fit in a standard kitchen cupboard


Compact dimensions

With a depth of only 285 mm the open vent Vitodens 100-W Compact 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.

Efficient, durable, quiet

The corrosion-resistant stainless steel Inox-Radial heat exchanger with particularly strong walls is extremely durable and achieves efficiency levels of up to 97%. The boiler's special design ensures the very low operating noise of 39 dB(A) maximum (26 kW), which is perfectly acceptable even in the kitchen.

Intelligent weather compensation

With a simple up-grade the Vitodens 100-W Compact can even operate in weather 
compensated mode without incurring a costly heating system modification.
Weather compensation acts like an auto-pilot as it detects outside temperature changes and automatically adjusts the flow temperature of the boiler, thus achieving gas savings of up to 12%.

Special warranty offer

The Vitodens 100-W Compact comes with a standard 5 year parts and labour warranty. The stainless steel Inox-Radial heat exchanger even features a 10 year warranty.

Versatile system solutions

Whilst being specifically designed for open vent heating systems, the Vitodens 100-W 
Compact is suitable for sealed systems using an additional expansion vessel safety valve. 
The boiler also shares the various flue options available for the Combi and System models of the Vitodens 100-W gas condensing boiler range.
