Outdated Product
High performance gas water heater that can easily supply hot water to city apartments and private houses. The model is positioned by the manufacturer in an affordable price segment. The rated power of the heat exchanger is 20 kW, which allows the device to prepare up to 10 liters of hot water per minute. Maintaining the mode selected by the user is controlled by the thermostat. The flowing water heater Roda JSD20-A1 has a compact energy-saving body, after installation it takes up a minimum of free space and looks good in the overall interior of the room. Let's pay attention to the open combustion chamber connected to the chimney with a diameter of 110 mm. The fuel is ignited by a battery-powered spark gap, and in cases of unforeseen extinction of the flame, an automatic gas control functio...n is activated, which prevents the possibility of fire and poisoning by toxins contained in the unburned mixture. The control panel has a small display, which makes the process of operating the device and setting the operating modes more visual.

Model overview based on user reviews  
The Roda R JSD20-A1 boiler is praised for its simple and convenient controls, quiet operation, and its ability to produce 10 liters of hot water per minute, which is a significant advantage. Users appreciate that it does not heat up on the outside, making it safe for various installations. The boiler is described as powerful and efficient, with convenient regulators and reliable ignition even with minimal water flow. However, one user reported a leak after six months, highlighting a lack of service support in Russia, which raises concerns about warranty reliability. Despite this, others have experienced no issues over extended periods, noting its build quality and low gas consumption. Overall, it is considered a great model with a competitive price, though potential buyers should be aware of the service limitations.

German reliability

Roda, a German company with Swedish roots, has been successfully operating in the global water heater market for over 35 years without questioning the quality of its products. The company's engineers create reliable gas water heaters that are resistant to high operating loads and with low gas quality requirements.

Classic design

A1 series JSD refers to models with a classic rectangular design and quite compact, especially in depth, dimensions (59x34x14 cm). The water heater can be safely placed even in a small kitchen. The protective casing is made of metal, covered with white powder enamel.

For the speaker to work and carry out automatic ignition, it needs 2 LR20 batteries, 1.5 V each. Alkaline is better, otherwise you will have to change almost every week. In order for the auto-ignition to work, a pressure force of 2 L / min of the supplied water is sufficient.

Control

Management is carried out by two handles on the front panel (gas supply level and temperature), between which the temperature display is conveniently located. The control over the operation of the burner is carried out visually — through a special slot on the front of the casing.

In terms of heating, you can safely count on 35-45 ºС, depending on the initial temperature of the water itself: with a throughput of 10 L / min, the JSD A1 heats the duct by 25 ºС. That is, if the temperature of cold water is 15ºС, then in a few seconds it already reaches 40 ºС. Such a performance can theoretically be considered to cover two points at once, but surely A1 will still work with only one.

Traction control

The model is reliably protected from overheating and is equipped with an innovative smoke control system. If the thrust suddenly disappears, the gas will turn off automatically within 30 seconds, which is two times faster than according to DSTU standards.

Roda JSD is a reliable, compact and inexpensive gas water heater that will delight its owners for many years.
