    Overview

    Introducing the Rinnai EnergySaver Flued Natural Gas Heater, a reliable heating solution that offers zero emissions, making it ideal for those with allergies or respiratory problems.

    This heater comes with an inbuilt humidifier tray, providing greater comfort during use. With the pre-heat mode, you can conveniently warm up the room up to 1 hour prior to the set programmed time. The digital temperature and time display allows for easy monitoring and control. The clean filter light indicator ensures that the filter is always in optimal condition. The economy mode helps to reduce running costs, making it an energy-efficient choice. The dual digital timers allow for convenient on and off programming for mornings and evenings. With low emissions technology and electronic thermostatic control, this heater ensures efficient and precise heating. The child lock or lock button provides added safety. In case of flame failure or power failure, the gas valves will automatically close. The overheat switch turns off the gas if the heater becomes too hot during operation.

    This product also comes with a 1.5m hose/cord for easy installation. With its heating capacity varying according to climate, ranging from 27m3 to 49m3, this heater can effectively warm different room sizes. The Rinnai EnergySaver Flued Natural Gas Heater is a reliable and efficient heating solution for any home.
    Organise your temperature

    The timer button can be used to set a delayed start or a delayed stop, depending on whether you want to program the heater in advance to suit your routine, or only run it for a limited amount of time, and avoid accidentally leaving it running all day.

    Discreet installation

    Rinnai has designed this heater with a slim profile, so it can sit neatly out of the way while keeping your room nice and warm. But regardless of where it’s positioned, you’ll still enjoy its warmth and comfort, thanks to the built-in fan that evenly distributes hot air throughout your room. The cool touch cabinet can be positioned fairly close to most furniture without much risk.

    Low Emissions Technology

    Rinnai gas heaters are highly efficient, with great energy ratings and low emissions you’ll be able to enjoy cleaner air and a more environmentally friendly household.

    Five year warranty

    With a 5-year warranty, you can rest assured knowing that your heater is backed by Rinnai for years to come.
