Bosch 11L heater under NOx butane gas Therm 4304

Bosch Therm 4304 11L

Atmospheric efficacy of low NOx for butane gas. Sign up by autonomous hydrogenerator, digital display and exclusive design Bosch.

Engineering Study: Autonomy by hydrogenerator and efficient modulation

In the projects to update hot water facilities, the operational simplicity and the autonomy of the team are key factors to maximize long-term reliability. The atmospheric heater Bosch Therm 4304 11 D Solvenant this need completely eliminating the dependence on external sources or fungible batteries. Its technological core incorporates an integrated hydrogenerator (Triple HD technology) that uses the kinetic energy of the input water flow to operate the electronic spark train and turn on the main burner. Its advanced combustion block of low NOx automatically modulates the power of the flame adapting it to the flow needs of the house. This stabilizes the output temperature and drastically reduces polluting emissions and the consumption of butane gas. Designed under connection standards Junkers traditional, it allows to replace the equipment directly, agile and without complex hydraulic modifications.

📈 Maximum efficiency with class A energy classification in a.c.s. according to the rigorous ERP European directives.

Exclusive design Bosch, low emissions of NOx and integrated digital control

Instant atmospheric heater Bosch Therm 4304 11 liters represents the natural evolution of traditional production systems. Conceived under the strict brand security guidelines, incorporates additional security sensors inside your chassis to control the correct evacuation of combustion products and water block temperature. Its low NOx refrigerated burner optimizes the combustion process, reducing polluting gas emissions to a minimum required by law.

The aesthetics of the heater has the different and exclusive design of Bosch, wearing purified lines that fit perfectly in any washing environment or semi-open kitchen. Its front interface integrates a very clear and intuitive digital display that immediately shows the state of the device, the water temperature and alerts of the control menu. Thanks to its wide range of automatic flame modulation of 19.2 kW of nominal power, the equipment effectively manages the consumption of butane gas and propane, administering rapidly to changes in hydraulic demand.

Prepared for future environmental challenges, the technical block has the H2 Ready certification, which supports its aptitude to operate with mixtures that contain up to 20% green hydrogen. By heating the water exclusively when it circulates by its high-strength copper exchanger, it avoids continuous fuel waste, becoming an excellent, durable and cost-effective option for households.

Installation criteria and Shot adequacy

To guarantee the optimal functioning of the atmospheric heater Bosch Therm 4304, the assembly must be carried out on a solid, vertical and leveling wall, always respecting the current local and state regulations on the location of atmospheric equipment. By not requiring network electrical connection or batteries, the physical location of hydraulic and gas jacks greatly simplifies direct replacement tasks from old heaters Junkers.

The natural shooting evacuation duct must have a strict nominal diameter of 110 mm, installing with an initial vertical section before any change of direction to ensure a correct natural shot of the fumes. It is advisable to verify the entry pressure of the butane gas supply on the injectors ramp to confirm the values recommended by the official technical service in the start-up, thus guaranteeing optimal performance of the modulating flame.
