Junkers HYDRO 4200 14-4 Natural Gas Atmospheric Water Heater

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

This atmospheric heater is characterised by its low NOx emissions, with only 35 mg/kWh, making it an environmentally friendly option aligned with the most demanding European regulations, such as the ErP regulation of February 2020. Thanks to its automatic flame modulation, it adjusts the power according to the hot water demand, optimising butane gas consumption and maximising 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. In addition, it includes an LED indicator that shows the operating status of the appliance, 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 in height, 425 mm in width, and 225 mm in depth, allows its installation in confined spaces without compromising performance. Moreover, its lightweight of 11 kg further facilitates its mounting. This model is compatible with the flue pipes of traditional heaters, so if it is a 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 output of between 11.9 kW and 23.6 kW, with a hot water flow rate of 3 to 14 litres per minute. Its minimum working pressure is 0.25 bar and a maximum of 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 with precision, adjusting degree by degree to optimise both gas and water consumption.
