If you are looking for the best floor standing combi boiler model, here are our top picks:
#1 Viessmann Vitodens 222-F (Best Floor Standing Combi Boiler)
Viessmann is one of the most renowned boiler manufacturers in Europe who has quite recently made a name for themselves in the UK too.
In fact, consumer organisation Which named them as the “most reliable boiler” some years ago.
The Vitodens 222-F is a premium option but offers everything you’d expect from a modern combi boiler design including a full colour LED interface and touchscreen controls.
This model also gives you the option to use either LPG or natural gas from the mains.
The model also enables you to use the Viessmann ViCare app on your mobile, allowing you to easily modulate and change their boiler settings remotely and conveniently.
Another advantage of the Viessmann Vitodens 222-F compared to other floor standing boilers and a major reason we placed it in position one is due to its very innovative 100L loading cylinder.
This feature ensures water pressure is well maintained, even on busy morning when multiple water outlets will be used simultaneously.
One major disadvantage of the Vitodens 222-F is it’s sheer size, at 600 cm wide and 140 cm high, it’s by no means a small or compact boiler design.

What is a Floor Standing Boiler?
A floor-standing boiler is large boilers that are typically too heavy to be mounted to a wall and therefore they stand on the floor.
Floor-standing boilers come in various shapes, sizes and run on a range of different fuel types. There are two main types of floor standing boilers as follows:
Conventional and systems boilers
These boilers are traditional types of heating systems that require a hot water cylinder system and expansion tank in addition to the boiler itself, to be able to work.
Conventional and systems boilers provide both heating and hot water and are typical of large size to provide sufficient energy for larger properties and families, however, due to their size, do require ample space.
In addition, these types of boilers can be powered via multiple energy sources such as gas, oil or LPG.

Currently, the installation of an eco-friendly biomass boiler is also supported by the Government’s Renewable Heat Incentive scheme or RHI.
