Viessmann Vitodens 050-W System Boiler (B0HA) 19kW and 25kW
The compact Vitodens 050-W as a system boiler, for homes with an unvented or vented hot water cylinder. Pump, expansion vessel and diverter valve are built in, so it suits straightforward system and S-plan replacements. Natural gas, LPG compatible.
- Inox-Radial stainless steel heat exchanger and MatriX-Plus burner with Lambda Pro
- ErP class A, modulation up to 1:8
- Built-in pump, 8 litre expansion vessel and 3-way valve for the cylinder
- Compact 400mm-wide casing
- ViCare app control with the ViCare thermostat
Required with this boiler: a flue kit
Viessmann boilers are supplied without a flue. The Flue kit selector above Add to cart adds the Viessmann 7946886 60/100mm horizontal flue kit by default, as a separate line in your basket.
Only choose "I already have this" if you already have a compatible Viessmann 60/100 flue, or you need a different route: see the vertical flue kit, extensions and bends. Only Viessmann flue components may be used with Vitodens boilers.

- Viessmann Vitodens 050-W system boiler (B0HA) in the selected output
- Control unit, integral safety valves, high-efficiency pump, 3-way valve and 8 litre expansion vessel
- Wall mounting bracket and boiler flue connection

Recommended add-ons
Tick these under the flue selector to add them to your order:
- Viessmann ViCare wireless thermostat ZK05991: app control and load compensation (Boiler Plus) on PlusBus Vitodens boilers.

- Viessmann 60/100 flue extension 1m 7373224: for walls thicker than the standard kit.
