Viessmann Vitodens Boilers

Viessmann Vitodens 11W - prices start from £1,113.00 plus VAT

The gas fired condensing boiler Vitodens 111-W is ideal for a flat or small family home, as well as larger properties with high hot water demand. It can easily be sited in an alcove in the bathroom, kitchen or utility room.

The modulating ratio over the entire output range is up to 1:6. This high ratio makes these boilers particularly suitable for use in small apartments and well insulated buildings. The user benefits from fewer appliance start-ups and therefore less operating noise. Because a lower level of stress is placed upon the appliance, the service life of components is consequently extended.

The Cylinder Loading System (CLS) ensures a continuous supply of hot water on demand. A standard bath (140 litres), for instance, fills in around 8 minutes, with a quick heat recovery of less than 5 minutes. A shower fitting, a kitchen sink or a washbasin, for example, can also be supplied with water, at the desired temperature, simultaneously (subject to cold water pressure and to tap flow restrictions).

The controller with built in room temperature sensor can be connected to an outside temperature sensor to run in weather compensation mode and the user-friendly dials allow rapid adjustment of the heating and domestic hot water temperatures, with a digital display showing operating conditions and temperatures. Sensors adjust the MatriX cylinder burner automatically to ensure the preset temperature is adhered to, even when running a bath or a shower.
