Boiler Central above the Worcester-Bosch alternatives recommends the Vitodens 111-W.
This is due to its build quality and capacity, as mentioned above. But let’s now dig into the Viessmann technical information below.

The Cylinder Loading System (CLS)
What else?? The Viessmann Vitodens 111-W includes the Cylinder Loading System or CLS.
Alternatively, most unvented cylinders make use of a heating coil in order to heat the cylinder.
The CLS technology actually replaces the coil with the plate heat changer.
A DHW pump will circulate the hot water back to the top of the cylinder.
Benefits of a Storage Combi Boiler
A storage boiler differs from a combi, regular/open vent boiler or system boiler as the storage boilers have a large hot water cylinder within the boiler unit.
Storage combi boilers such as the Viessmann 111-W save space by getting rid of the need to have a separate hot water cylinder unit or tank.
It is all compact and in one unit, which makes it easier to manage and repair.
This is why our Viessmann Vitodens 111-W review is so easy to get an in-depth picture of why we recommend it, as it really is a fantastic unit with the integrated cylinder.
There are many different boiler types and boiler sizes available to determine which storage combi is best for your property.
For example, Viessmann offers a range of smaller storage combi boilers suited for properties with two or more bathrooms.
The supply of the Vitodens 111-W is equivalent to 150L of water! Enough for most families small and large.
