Outdated Product
Double-circuit condensing boiler running on gas. Recommended for use in heating and hot water supply systems of apartments and houses up to 197 m², in which medium-sized families live. In maximum power mode (24.6 kW), the Bosch Condens GC1200W 24 C 23 boiler consumes no more than 2.47 m³ of gas per hour. The temperature of hot water in the tap, which is heated at a rate of up to 11.1 l / min, can be adjusted in the range from 35 ° C to 60 ° C. The temperature of the coolant in the heating circuit can reach 82 ° C. Stainless steel heat exchanger ensures the reliability and durability of the equipment. Quiet operation of the circulation pump and fan removing flue gases guarantees the absence of excess noise from the boiler. The EMS bus allows you to connect the smart Bosch EasyControl controller...(purchased separately) to the device, with which you can control the heating system from a smartphone or tablet. Safe operation is ensured by protection systems against overheating, flame extinction, lack of draft in the chimney and pressure drop in the gas main.

Efficient heating system

The Bosch Condens GC1200W 24 C 23 combi boiler with a 24.6 kW output delivers effective heating for residential, office, and commercial spaces from 40 to 197 sq m, as well as domestic hot water at 35–60 °C. A condensing heat exchanger, a gas‑air mixture regulator with intelligent electronic control, and a multi‑speed circulation pump provide efficiency up to 108% and allow flexible power adjustment for different operating conditions. At the same time, maximum gas consumption does not exceed 2.47 m³/h, which is an excellent figure for this class. The model comes with a standard set of safety systems protecting against overheating, pressure fluctuations, flameout, and lack of draft.

Installation and operation

The sealed, fan‑assisted combustion chamber simplifies installation in rooms without ventilation shafts and without the need for constant airing. The boiler stands out for its low weight (24.5 kg) and compact size, making it easy to install even in tight spaces. A clear display and built‑in software let you configure key operating parameters, while the control board is compatible with external programmers and the Bosch EasyControl system for remote control via smartphone. It’s also worth noting the stainless steel heat exchanger, which is resistant to condensate and delivers long‑lasting performance without signs of corrosion.
