Bosch Therm 4204 14 Litres Methane open chamber gas water heater 7736504911

Maximum safety:

• Triple safety system consisting of the flue gas sensor, temperature limiter and a control device that interrupts the flow of gas in case of failure to ignite or accidental shutdown.

Easy to install:

• It does not require electrical connections because it is battery powered. It is also designed to minimize NOx emissions and can be combined with solar thermal systems for the production of domestic hot water (through a special accessory).

Optimized consumptions:

• The gas consumption of the water heater is adapted to your real needs, thanks to the continuous modulation of the flame.

New design:

• Discover the new elegant and modern design. New rounded aesthetics and intuitive management thanks to the front display.

ADVANTAGES:

• Safe: triple safety system consisting of the smoke exhaust sensor, the temperature limiter and the control for the interruption of gas flow in case of failure to ignite or accidental shutdown
• Optimized consumption: continuous modulation of the flame for a gas flow adapted to the real needs
• New design: elegant and modern with new rounded aesthetics
• Sustainable: low NOx emissions
• Flexible: no electrical preparation is necessary thanks to the battery power supply and can be combined with solar thermal for DHW production (through a special accessory).
