CONDENS 2300 W 
The energy efficiency of condensation and the elegance of a modern design meet in Condens 2300 W, the Bosch wall-mounted gas condensing boiler for heating and domestic hot water production. The extremely compact dimensions of this boiler make it the ideal replacement when you decide to replace your old one.
Extremely Compact and Simply Easy to Install
The Condens 2300 W is designed to fit anywhere: its compact size makes it easy to install in any home, making it an ideal solution for modernization projects. Installing the Condens 2300 W, even during renovations, is very simple: its compact size makes it extremely versatile, and since it adapts to a variety of layouts, it doesn't require moving the flue pipe. Various accessories are also available to assist with installation. Maintenance is also simplified, thanks to the ability to remove the side panels for easy access to the components.
Modern and functional, both inside and out
The Condens 2300 W combines the use of premium materials, designed to last, with a sophisticated and functional design, highlighting the modernity of this boiler both from the front and the back. The components are top-quality, starting with the aluminum-silicon exchanger, a guarantee of robustness and reliability over time.
First-class reliability
Thanks to the Al-Si WB6 aluminum-silicon alloy primary heat exchanger and the option of solar thermal integration, the new boiler offers maximum efficiency and an excellent price-performance ratio. The aluminum-silicon heat exchanger gives the Condens 2300 W robustness, quietness, and reliability, the same characteristics as higher-end boilers.
Modulation ratio 1:10
The Condens 2300 W is synonymous with efficiency thanks to its modulating burner with a 1:10 range that automatically adapts to current heat needs, achieving very high seasonal energy efficiency for space heating, with values up to 94%. Thanks to its wide modulation range, this boiler also provides plenty of hot water at a constant temperature.
Maximum seasonal performance
The Condens 2300 W guarantees significant energy savings, thanks to its 94% efficiency rating, the highest achievable for a condensing boiler. Furthermore, when combined with modulating thermoregulation with climate control, the Condens 2300 W achieves an A+ energy efficiency rating and qualifies for tax incentives of up to 65%.
EasyControl Thermostat

Using the Easycontrol thermostat, you can also manage the boiler remotely.
Bosch's revolutionary EasyControl thermostat lets you manage your home via app, wherever you are. All you need is an internet connection on your smartphone to control the temperature in every room of your home directly from work. The app ensures continuous control over your system, allowing you to set weekly schedules for both heating and domestic hot water.
Remote control also helps you in some special situations: the kids are leaving school early and are about to return home, but normally no one is home at that time, and you've set the temperature to 19°C? No problem! While the kids are returning home, you can slightly raise the temperature directly from work using the EasyControl thermostat app, so they'll find the perfect temperature when they arrive. Furthermore, the app lets you monitor your energy savings by tracking your annual, monthly, and weekly consumption. Finally, in the event of a malfunction with your heating system, you can request immediate assistance with a simple tap, directly from the app installed on your smartphone. The app is available for Android and iOS devices.
