The Viessmann Vitodens 100-W is a wall-mounted gas combination boiler delivering a 35kW output to meet rigorous heating and hot water demands in modern domestic properties. Engineered with a high-grade Inox-Radial stainless steel heat exchanger this unit maximises thermal transfer while ensuring long-term durability against corrosion. The integration of a patented MatriX-Plus burner coupled with Lambda Pro combustion control facilitates a wide modulation range of 1:10. This allows the appliance to dynamically adjust its output down to lower levels during reduced demand periods yielding an ErP Class A efficiency rating of 98% and minimising fuel consumption.

Measuring 700mm in height by 400mm in width and 360mm in depth the compact chassis is designed for discreet integration into standard kitchen cabinetry. The system incorporates an 8L expansion vessel and a variable speed high-efficiency circulation pump alongside an intuitive LCD touchscreen display for streamlined commissioning. Built-in WiFi connectivity provides engineers and end-users with remote diagnostic capabilities and smart thermostat integration via the ViCare application. The boiler is fully compatible with LPG without requiring an external conversion kit.
