A desire to offer appliances that encapsulate the highest levels of energy saving while at the same time being extremely safe and easy to install and use has led to the utilisation of innovative technologies that has allowed the elimination of plugs and cables and with it the complications those elements have brought to the user and installers over the years. An ignited pilot flame consumes 13 grams of butane per hour, multiply this quantity by 24 hours for 365 days a year and the saving equates to around 9 or 10 butane gas cylinders per year. In the case of natural gas this would result in around 120 cubic meters per year. This as opposed to only the two normal LR20 batteries that should provide you service for roughly a year. Bosch has made it possible to have a water heater without a pilot burner. The elegant design of the unit enables it to be seamlessly integrated into any kitchen with consummate ease. Besides the elegant cover, an ignition switch, a green luminous indicator to indicate that the flame is present in the water heater as well as a red indicator light to signal a low battery are present.
