Viessmann Vitodens 200-W
The Viessmann Vitodens 200-W domestic boiler range comprises condensing boilers designed to cater for houses of all sizes and heating requirements. The gas fired condensing boilers offer advanced technology and features including an 'Inox Radial' stainless steel heat exchanger which ensures maximum fuel efficiency and cuts down on fuel wastage - offering potential fuel bill savings. The range also features a 'MatriX' cylinder burner which again helps to provide an operational efficiency of up to 98% on a consistent basis.
The gas-combi boilers in the Vitodens 200-W Range come with a DHW standby function offering hot water on instant demand and at the required temperature - which can be set in advance. The operation is very quiet. The range also only requires minimal servicing as the stainless steel surfaces are self-cleaning, and condensation/flue gas is designed to flow in the same direction - again minimising build-up.
Another feature of the range is that it's highly efficient and has low emissions. It is also loaded with features and diagnostics are simple due to its digital display. The casing is slim and compact and the design is discreet - which allows the boiler to be simply installed in small spaces if required with flexible siting. Installation is again designed to be quick and easy.
Key features include- SEDBUK A rated - the top mark of heating efficiency
- High tech heating capability with flexible output options
- A 3 year warranty as standard
- A lightweight compact and modern design
- Incredibly easy to operate

Do not purchase this boiler unless you have a fully insulated, new-build home. It is entirely unsuitable as a replacement unit. The reason for this is that the 200W has a basic design flaw in that it uses a diverter valve to provide heat to EITHER the radiator circuit OR the DHW cylinder but NOT both at the same time. The Viessmann documentation is in error when it says that you CAN have both at the same time. In practice, whenever you use any domestic hot water, the radiators immediately go cold because the diverter valve switches all heating to the DHW. The system relies upon the house being sufficiently well insulated that the loss of heating goes unnoticed. However, the worst part of dealing with Viessmann is that their idea of solving a customer's problems appears to be that they simply ignore them. Do not even bother to write or email to Viessmann in England or Germany because, from my experience, they will simply ignore your correspondence even to the point of refusing to acknowledge having received it. If you do manage to speak to them then everything is always your fault and never Viessmann's fault. One final point to bear in mind is that the boiler is "too clever for its own good". It would seem that it has been made deliberately complicated to configure in order to prevent the user from understanding it. Unfortunately, it also appears to have the same effect upon the Viessmann engineers and their trained installers who, from my experience, do not seem to know what they are doing. All of this is a great pity because the boiler appears to be well constructed. Caveat Emptor!
