Viessmann Vitodens 100-W 11kW System Boiler B1HF (7723177) ZK06230

This is the boiler all installers should be fitting in the majority of homes! With a modulation ratio of 3.2kW to 11kW on space heating, it will easily cover the majority of homes in the UK, which have an average heat loss of about 7kW at -3 degrees C outside. This boiler uses the same heat exchanger as the 19kW version, and is programmed to give 17.5kW to DHW if you use the 100-W system boiler in 4 pipe mode (gas pipework needs to be designed accordingly). This boiler works amazingly well using the new Vitotrol 100-E, however with OpenTherm as standard on this appliance, it also works brilliantly with 3rd party OpenTherm controls!

***Boiler, gas valve, heating flow & return valves included. If piping up as a 4 pipe boiler, this product requires an additional valve set & Viessmann hot water controls. These items are sold separately. Outdoor sensor for weather compensation not included. Contact us for help or information.***
