Viessmann Vitodens 200-W 19kW System Boiler B2HF (7956234)


Available on back-order

Viessmann Vitodens 200-W 19kW System Boiler B2HF (7956234) Z020312

All Viessmann Vitodens 200-W System boilers come complete with an Outside Weather Compensation Sensor. They can be directly mounted to the wall, but you need to add one of the fitting kits applicable for the application to your order. They have the direct mounting option (with the supplied wall bracket), which would require fitting kit ZK04669 for downwards piping or fitting kit ZK04670 if it was a stud wall and you are piping into the rear of the bracket. If you want to pre-plumb the installation, you can use a pre-plumbing jig ZK04307 if you are piping the boiler from below or ZK04308 if you are rear piping the boiler. If you are using the Viesmann Vitodens 200-W system boiler as a heat only boiler, you need the Locking Caps (ZK02164) to cap off the DHW outlets on the bottom of the boiler. The entire Viessmann Vitodens 200-W range uses the same flues as the 050-W and 100-W boilers and flue accessories can be found here – FLUES.
