Compact heating and hot water solution
The Bosch Condens 1200 W GC1200W 20/22 C 23 is a wall-mounted combi condensing gas boiler designed to provide both central heating and instantaneous domestic hot water.
Its maximum heating output is 20 kW, while the domestic hot water output is up to 22 kW. The minimum nominal heating output is 5.2 kW. Boiler selection should be based on the calculated heat loss of the property, the design of the heating system and the required hot water capacity.
With dimensions of 665 × 395 × 285 mm, the boiler requires relatively little installation space. It can be installed in a kitchen, utility room or another suitable location, subject to the applicable technical requirements.
Before installation, the existing gas pipework, heating connections, water connections, condensate drainage and flue system must be inspected.
