High-quality geyser from a well-known manufacturer
The Bosch Therm 4000 O WR 13-2 P geyser is equipped with a heat exchanger with a rated power of 22.6 kW. Thanks to this, the device quickly heats the water, despite the increased performance (compared to average instantaneous water heaters), which reaches 13 l / min at maximum power. The power of the gas burner is regulated by a "slider", and the water flow - by a rotary regulator. At maximum capacity, the gas consumption is 2.8 m³/h. This speaker works well with low gas pressure in the line and even with a barely open hot water tap (a flow of 2 l / min is enough for the burner to ignite). The device easily and confidently flares up, without being accompanied by anguish and cotton. During operation, it sensitively reacts to changes in water pressure and automatically maintains a constant temperature of the liquid at the outlet. A piezoelectric element is used to ignite the speaker, so the wick is constantly burning under the burner. The continuous "eternal flame" inside the speaker can be confusing for those who are not used to water heaters with piezo ignition. In addition, a burning wick constantly consumes gas, although in small quantities - only 0.012 m³ / h.
Advantages and disadvantages
The design of the Bosch Therm 4000 O WR 13-2 P geyser is simple and contains virtually no electronic components, with the exception of several sensors that provide a multi-level security system by monitoring the water temperature, the presence of a flame and reverse draft. Thanks to its simplicity and European assembly (this series of devices has been produced exclusively in Portugal for many years), this device can serve for a long time. Practice shows that the heat exchanger and water control valves are very reliable (subject to timely cleaning in accordance with the instructions), and maintenance and repair of the speaker are simple and inexpensive.
Unlike operation, installation of the Bosch Therm 4000 O WR 13-2 P speaker can be difficult. Branch pipes for connecting gas and water are 3/4 inch. Therefore, customers with 1/2 inch tubing (typically most customers) will need special hose adapters. Also, the cold water supply was not made very well (the connector is not directed downwards, but directly into the wall, which makes access to it inconvenient). You may need an additional corner outlet to connect the speaker to the water supply.
