Bosch Condens 2500 WBC 28-1 DC 23 condensing gas wall-mounted boiler

The condensing boiler Bosch Condens 2500 WBC 28-1 DC 23 is designed for heating private houses, cottages, country houses, summer cottages up to 250.0 sq. m. and also for the organization of hot water supply.

By default, the boiler runs on natural main gas, but if necessary, the boiler can be converted to work on liquefied gas, for this you need to purchase a set of jets. In its design, the heating boiler already has a Wilo circulation pump, so there is no need to purchase it

To operate the control board of the condensing boiler, it must be connected to a 220 V electrical network. To maintain the warranty, manufacturers recommend installing a voltage stabilizer. How to choose a stabilizer, you can consult our specialist.


A closed combustion chamber (in other words, such boilers are called turbocharged) implies the presence of a fan in this boiler, which forcibly takes in air and removes combustion products to the street or a collective chimney. For such boilers, coaxial chimneys are usually used - "pipe in pipe"
