Both boilers recently secured Which? Best Buy status for the second year running.

The Vitodens 111-W combi has integrated hot water storage and is available in outputs from 4.7-35kW. It has the capacity to fill a standard bath in just eight minutes, whilst also supplying a sink or washbasin simultaneously.

The Vitodens 200-W is compact, quiet and incredibly efficient with a 1:20 modulation range, Lambda Pro Control Plus controls and 98 per cent efficiency. Good news for installers is the 200-W’s push-fit system. By installing the appliance on the bracket of the installation jig, all heating water and DHW pipes are already securely connected to the heating system – without the need for threaded fittings, clamps or soldering. The boiler can be controlled from anywhere with an internet connection via the ViCare app.

Both boilers are energy efficiency class A and Boiler Plus ready.

Visitors to the Viessmann stand (stand 74) will also be able to examine the Vitodens range’s high quality heat exchanger, fan and gas valves and hydrobloc with PRV. Staff will be on hand to discuss new Boiler Plus legislation measures such as weather compensation.
