New Vitodens 025-W Combi Boiler Press Release

Small, pre-commissioned boilers with very attractive price/performance ratio are easy to install and operate.

TELFORD, UK, February 2025 — Viessmann Climate Solutions UK has expanded its comprehensive range of high performance, reliable combi boilers for the newbuild and modernisation sectors with the launch of the compact and efficient Vitodens 025-W. Viessmann Climate Solutions UK is a part of Carrier Global Corporation (NYSE: CARR), global leader in intelligent climate and energy solutions.

With two output choices of 24 kW and 28 kW, the Vitodens 025-W comes with two years warranty as standard, extended to five years for installations that are registered on the Viessmann installer portal as well as a 10-year heat exchanger warranty.

With an integral instantaneous water heater, the wall-mounted gas condensing combi boiler is ideal for living areas with limited space due to its low operating noise (48 dB for the 24 kW model and 51 dB for the 28 kW) and very small size (300x400x700mm).

Each pre-commissioned unit is also exceptionally quick and easy to install and maintain. No side clearance is required as all components and connections are easily accessible from the front, while only two button pushes are needed to complete each installation.

Operation is very straightforward too, either remotely or via an inbuilt control unit with just four buttons and a white LCD screen.

Chris Johnson, UK Director of Sales at Viessmann Climate Solutions UK, Carrier RLC EMEA

It has been designed with the housing specification market in mind and for those installers who do wish to connect to Viessmann’s digital services.”
