Viessmann Vitodens 025-W 24kW Combi Boiler BPKB

More About The Viessmann Vitodens 025-W 24kW BPKB

Equipped with Viessmann’s patented Inox-Radial stainless steel heat exchanger

The patented stainless steel heat exchanger makes the Vitodens 025-W 24kW combi boiler both efficient and long-lasting. Viessmann put this heat exchanger in all their boilers, unlike some other manufacturers. When put up against aluminium, stainless steel is a far superior material.

Aluminium heat exchangers allow for excellent performance and provide high heat transfer. But, this performance will degrade over time, and stainless steel won’t. Aluminium exchangers become more prone to corrosion from chemicals added to the system. Due to this, they cannot be used with softened water.

The Vitodens 025-W features high corrosion resistance at various pH levels. It does not need extra maintenance fluids and will last longer than aluminium. To back it up, the heat exchanger in the 025-W has a 10-year warranty from Viessmann.

Easy operation

Operating the 025-W 24kW is simple thanks to the new LED screen and on-board controls.

The latest model is compatible with Tado, Hive and Nest smart thermostats. But we wouldn’t recommend Hive for Viessmann boilers as it is not Open Therm compliant. So pairing a Hive and 025-W wouldn’t allow you to take full advantage of modulation.

Viessmann have their own smart thermostat too. The ViCare+ Climate Sensor thermostat and app are great products. We recommend the ViCare+ system because it will follow the boiler’s 10-year warranty. Like other smart thermostats, it allows daily routines, boosting, and temperature control away from home. It’s available for Android and iOS.

Although we can install Nest systems, their customer service isn’t great. So if the unit breaks you could be left without heating.

Boiler reset

Like all modern devices, sometimes a boiler needs to be reset. The 025-W 24kW is very easy to rest. The Boilerhut engineer will show you how to do this once the installation is complete. Press the up and down temperature arrows for approximately four seconds. A rotating bar will appear on the display. This indicates that the restart process has started.

All components manufactured in-house

All components used within this boiler are made in Allendorf, Germany. This is Viessmann’s main Vitodens facility. This in-house production is key in keeping their premium product at a lower price.

Wide availability of parts

When Viessmann first entered the UK market, parts were hard to find. Viessmann addressed this in the mid-2010s. Now, all boilers and parts are available from most plumbing merchants such as Plumbase.
