Junkers HYDRO 4200 14-4 natural gas atmospheric heater

The Junkers Hydro 4200 WR14-4 KB 31 JU butane gas atmospheric heater is an efficient and environmentally friendly solution for supplying hot water in the home. This model, with a capacity of 14 liters per minute, combines advanced technology with a compact and exclusive design from Bosch, ensuring comfort, savings, and optimal performance to meet the needs for sanitary hot water (ACS) in domestic installations.

This atmospheric heater is characterized by its low NOx emissions, with only 35 mg/kWh, making it an environmentally friendly option that complies with the most stringent European regulations, such as the ErP regulation from February 2020. Thanks to its automatic flame modulation, it adjusts the power according to the demand for hot water, optimizing butane gas consumption and maximizing energy efficiency, with an efficiency of up to 88%.

The ignition of this heater is automatic via batteries, meaning it does not require an electrical connection, facilitating installation and use in places where electricity may not be readily available. Additionally, it includes an LED indicator that shows the operating status of the device, providing the user with simple and direct control over its operation. The pilot flame ignites only when necessary, reducing gas consumption and improving long-term savings.

The compact design of the Junkers Hydro 4200, with dimensions of 655 mm high, 425 mm wide, and 225 mm deep, allows for installation in tight spaces without compromising performance. Moreover, its lightweight of 11 kg further facilitates its assembly. This model is compatible with the flue ducts of traditional heaters, so in case of replacement, it will not be necessary to change the gas outlet, reducing both installation time and costs.

Another notable advantage of this heater is its ease of installation and maintenance. The hydraulic and gas connections follow Junkers standards, ensuring quick adaptation, especially if replacing a previous heater of the same brand. It also features additional safety sensors inside, ensuring safe and reliable operation at all times.

In terms of performance, the Junkers Hydro 4200 offers a useful power of between 11.9 kW and 23.6 kW, with a hot water flow rate of 3 to 14 liters per minute. Its minimum working pressure is 0.25 bar and maximum 1 bar, ensuring a constant flow of hot water even in low-pressure situations. Additionally, the heater includes a temperature regulator so that the user can select the desired temperature precisely, adjusting it degree by degree to optimize both gas and water consumption.
