Outdated Product
Energy-efficient and relatively compact condensing double-circuit gas boiler of medium power with a closed combustion chamber. Refers to the models of the Bosch Condens 2500W family of 2017. Compared to double-circuit gas boilers of traditional design, it has a significantly higher efficiency, which, with the same nominal heat output, provides gas savings in volume up to 8%. Such significant savings are achieved due to the additional cooling of the combustion products, which helps to extract the latent heat of condensation of water vapor. The use of a closed combustion chamber and a forced smoke exhaust system allows you to install the Bosch Condens 2500 WBC 28-1 DC boiler directly in residential areas. Its claimed useful thermal power of 24 kW is enough for heating and hot water supply of...a house/cottage, a spacious urban city apartment, a commercial or utility room with a total area of up to 192 m2. The high reliability of the device is ensured by the use of proven engineering solutions and high-quality materials. The boiler is capable of providing rapid preparation of hot water in an amount of up to 13.3 L / min (when heated at 20 °C). Features a backlit LCD display and Heatronic 3 microprocessor control system that is compatible with a wide range of thermostats and function modules.

FAQ: 10 frequently asked questions about heating boilersAnswers to common questions in the section "heating boilers"

Forced removal of combustion products

The turbocharged condensing gas boiler Bosch Condens 2500 WBC 28-1 DC of a well-known German manufacturer of household and professional appliances is, first of all, high reliability and complete safety. A wall-mounted double-circuit device with a thermal power of 24.1 kW can heat rooms up to 192 m2 and organize a comfortable hot water supply with a temperature of 40 – 60 °C with a flow of up to 13.3 L / min with a difference in inlet and outlet of 30 °C. A closed combustion chamber and exhaust gases through a coaxial pipe greatly facilitates installation and makes the operation of the boiler in any residential area absolutely safe. The use of the energy of hot gas condensate adds efficiency to the device, increasing the efficiency to a conventional value of 110%.

Convenient access to elements from the front panel

The device has a compact size and practical design. The simple layout of nodes and thoughtful design allows you to access each element of the device from the front side. The boiler is equipped with a wide-range modulating burner with a pre-mix unit, a powerful heating circuit heat exchanger and a plate heat exchanger for continuous hot water preparation. In addition, it is equipped with a gas valve, a pressure gauge and an expansion tank with a capacity of 6 liters. The control panel with bright white pictograms and numbers on a black LED-display provides easy monitoring of the status of the systems, and 4 adjustment buttons to a minimum simplify the setting of operating modes. The electronic control unit supports all existing types of Bosch thermostats and control devices, including programmers and control modules via the Internet. It is also possible to integrate the boiler with a solar collector system. Connecting a room temperature controller and weather-compensated automation controllers gives up to 10% gas savings.
