The Nefit 9700i is future-ready: internet-enabled, ready for hybrid systems, and prepared for a mix of natural gas and hydrogen. The modern boiler can be combined with a room thermostat of your choice, such as the wireless internet thermostat CR20 RF with the Bosch HomeComfort app, or the smart Bosch EasyControl thermostat in combination with the EasyControl app. This allows you to easily regulate the temperature in each individual room of your home.
New Low Energy-High Performance Boiler Pump
The 9700i is up to 75% more efficient due to its high modulation range. The high hydraulic efficiency ensures maximum efficiency. Additionally, the intelligent speed control is based on both the device's power and pressure difference, resulting in optimal performance.
