    When your home is equipped with a Bosch hot water system you can be sure your unit is meticulously engineered for efficiency, reliability, and convenience. This Bosch 16-litre continuous flow system provides sufficient hot water supply for a small household.

    Due to its compact design, it can be installed in small apartments or locations with restricted space. The high preset temperature lets you use very hot water in the laundry or kitchen, making this an ideal option for busy households who require flexibility for their cleaning and laundry needs. This system runs on natural gas, and uses automatic hydropower ignition so it does not need an electric power connection.

    For a space-saving and efficient solution for your hot water needs, this internal compact hot water system from Bosch is a reliable choice.
    High temperature system

    This hot water system can be adjusted to temperatures higher than 50°C, if your laundry or kitchen requires hotter temperatures. If you need a higher temperature, the installation of tempering valves for bathrooms is required to prevent accidental scalding.

    Suitable for small households

    This hot water system has a hot water flow rate of 16 litres per minute, making it suitable for homes with one bathroom. If you have a small household consisting of one to three people, this should be well-suited for your household.

    Efficient engineering with LPG gas

    This exceptionally efficient hot water system heats water with LPG gas, and is designed to ensure low running costs and low emissions of greenhouse gases. A design that is kinder to your budget and the planet.

    Compact design

    Thanks to the continuous flow system, you don’t need a big storage cylinder to keep hot water. This makes this system a compact solution for your hot water needs, making it easy to find a place to install the unit.

    Amazing value
    Great temperature range for the shower, I have the settings to minimal gas usage and still get hot hot water. Minimal complaint on assembling cover over dials and initial energizing of system but for this price that is a tiny tiny step down from perfection. Once its set up its as good as any (probably better than many) (Reviewed after about a month of usage)
