Compact and light, the Viessmann Vitodens 100-W Heat Only Boiler is the perfect size for installation within a sized kitchen cupboard, or any area where space is limited. The corrosion-resistant stainless steel Inox-Radial heat exchanger with unrivalled wall thickness, 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. 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 autopilot 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. All of which add up to an incredibly reliable, but quiet and efficient system.
