In more depth: Why we recommend the Viessmann Vitodens 111-W
The Vitodens 111-W is recommended by Boiler Central above the Worcester-Bosch alternatives. This is due to its build quality and capacity as mentioned above. But let’s get more technical.
Being fitted and equipped with a stainless steel loading cylinder with a 46 litre capacity, the Vitodens 111-W has the ability to have on demand hot water for the entire family.
The modulating ratio for the entire output range is up to 1:6. This means that this boiler can easily handle small apartment buildings and anything well insulated.
With this, the user will benefit from appliances starting up less and therefore results in lower operating noise.
It also means that the service life and operating functions of the boiler last longer and vastly extends boiler life.
As we have mentioned in our other articles with Viessmann Boilers, they contain the brilliant Stainless Steel Heat Inox-Radial Heat Exchanger.
This helps for the highest efficiency of up to 98% while being exceptionally reliable with fully working operability during its long life of service.
Viessmann are so confident about their Stainless Steel Heat Exchanger, that they offer a brilliant 10 year warranty against leaks resulting from corrosion.
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 up 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 iis equivalent to 150L of water! Enough for most families small and large.
