Established in 1917, Viessmann draws on more than 90 years of experience in the development and manufacture of heating systems and due to its high commitment to
quality, it is Europe's single largest brand in heating technology. Viessmann is a third generation family business and as such is able to hold true to its principles of innovation, efficiency and sustainability; which is a significant reason behind Viessmann's continuing success.
Viessmann offers three year warranty as standard on range of Vitodens 200-W gas-fired condensing boilers, which is increased to a five year warranty if fitted by a Viessmann trained installer.
InoX-Radial heat exchanger
Stainless steel is, without doubt, the best material for primary heat exchangers in condensing boilers. One of the unique design features of all Vitodens boilers is the Inox-Radial heat exchanger made from high grade stainless steel. The spiral wound tube, with rectangular profile is designed to ensure a laminar flow without a boundary layer for excellent heat transfer. ( It has a large bore which cannot be blocked by crud from the system )
This self-cleaning component is so reliable that it is guaranteed for 10 years
With the increasing cost of fuel, boiler efficiency is becoming more and more important. The only way to improve the efficiency of a good quality condensing boiler is to add weather compensation controls.
The Vitodens 200-W Combination and System* models are designed to work with optional weather compensation controls, to achieve additional fuel savings of up to 12%-meaning huge savings every year, for a small initial outlay.
The Vitodens 200-W is available* with either a Vitotronic 100 HC2A constant temperature controller or the Vitotronic 200 HO1A weather compensation controller, both controls have a 7 day programmer. Navigation is as easy as can be and mirrors the well known scroll wheel you are familiar with from mobile phones or TV remote controls. It features a multi-line plain text display with large fonts. The display is 70% larger than those of comparable devices, can show graphics and is also back-lit.
The Vitotronic 200 HO1A, used with an outdoor sensor, can control up to 3 heating circuits, 2 mixed and 1 unmixed, e.g. underfloor heating and radiators would
be run off the mixed circuit and a towel rail would run off an unmixed circuit and a separate DHW Circuit
