    Overview

    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 LPG 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.

    Note: the hot water system in the video refers to the 10-litre natural gas model. This is the 16-litre LPG model.
    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.

    Questions & answers

    Can we install this item in a cupboard with a 9kg gas bottle Jules · 2026-01-21
    Hello Thank you for your question regarding the product. The short answer is NO; you are not allowed to connect any products to an LP gas bottle inside any property. The gas bottle must be located outside the property, and a qualified plumber should run gas plumbing​ piping from the bottle to the appliance. There are Australian regulations governing the connection of any product to LP gas. If you are installing the hot water system indoors, it must also be properly ducted using optional extra ducting pipe, which the plumber uses via the outlet at the top of the system to expel all burnt gases. I hope this information will assist you when shopping with us at Appliances Online. Our Sydney-based team is available 24/7 to assist you at Ph: 1300-000-500. Colin Jones, Appliances Online
