The Viessmann Vitodens 100-W is an advanced 30kW combi boiler engineered to deliver strong hydraulic performance and low emission central heating. At its core lies a durable stainless steel Inox-Radial heat exchanger which operates alongside the proprietary MatriX-Plus burner. This combination features a broad 1:10 modulation range, automatically adjusting the thermal output to match exact household demands while minimising cyclical short-cycling. The fully automatic Lambda Pro combustion system continually monitors and adapts to varying gas qualities, ensuring the appliance operates smoothly whether connected to natural gas or directly to LPG without the need for a physical conversion kit.

Designed with modern infrastructure in mind, this ErP A-rated boiler features an integrated WiFi interface enabling immediate connectivity to the ViCare app for remote system diagnostics and thermal scheduling. The front fascia incorporates a discreet black panel LCD touchscreen that provides installers and homeowners with clear access to boiler parameters and operational statuses. Supplied fully wired and plumbed with an internal 8-litre expansion vessel and an energy-saving variable speed circulation pump, it represents an efficient, future-proof solution for contemporary domestic heating networks.
