425

Patented Bosch Hydro-Generated Ignition Technology. The Bosch engineers have proven that water can indeed make fire. The pilot is ignited by a super-concentrated spark generated by a micro-turbine. The micro-turbine is activated by a request for hot water in the house. This energy efficient technology makes the 425 HN ideal for households looking to maximize energy savings. No Electricity Required.
