Condensing boilers fit into kitchen cupboard
Capable of being installed in a standard 300 mm kitchen cupboard is a range of open-vent condensing boilers from Viessmann. The Vitodens 100-W Compact range comprises four models with outputs from 13 to 26 kW, and they are just 285 mm deep.
These boilers use the stainless-steel Inox-Radial heat exchanger and can operate with optional weather-compensation control without the entire heating system having to be upgraded. The flow temperature of the heating system can be reduced with no effect on DHW performance.
These boilers have a 5-year parts and labour warranty. The heat exchanger has a 10-year anti-corrosion warranty.
