VITODENS 100-W HEAT ONLY

A compact and efficient heat-only gas boiler

A heat-only, wall-mounted gas-fired condensing boiler which is compact enough to fit in a standard kitchen cupboard. Also suitable for use in other applications with limited space available.

Key Benefits
Efficient, durable, quiet
The corrosion-resistant stainless steel Inox-Radial heat exchanger with unrivalled wall thickness is extremely durable and achieves efficiency levels of up to 93%.

The boiler's special design ensures a very low operating noise of 39 dB(A) maximum (26 kW), which is perfectly acceptable even in the kitchen.

Inox radial burner
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.
