    Top water heater. Have used Duoetto previously, only on 240v, but found it very efficient and quick to heat.

    This compact hot water unit is amazing, It is really easy to install and SO efficient !! AusJ’s customer service is second to none, order with total confidence. If you have any questions like i did, they are more than willing to help. It’s the best little water heater out there !!

    Great product for mobile use in vans or campers. This water heater runs on 12V and is very easy to set up and use. No gas needed. I recommend switching it on while driving if you’re charging off your alternator. It uses less battery than I thought and ending a day of hiking and touring with a hot shower is fantastic.

    I would recommend this hot water heater, It is compact, efficient, heating quickly on 12v or 240. Safety features of preset temperature choice, shut off if hot water tank water is low and pressure overflow hose, Sensors saving power by knowing when to turn on and off as temperature drops when in use, Selects best heating option when 240 and 12v available, When on the move I turn the heater on about 35 minutes before reaching my destination and arrive with 50 degree water. Time and use will show how good this product is, but so far very happy with my choice.
