Easy Hot Water. Good value water heater and easy to install. Works well.

I installed a Duoetto 10 litre hot water system in our Jayco Eagle Camper Trailer and we have had several trips using it in both 12volt DC and 240volt AC.

I installed the unit under the front lounge just inside the side access hatch near the front door. This location has proved itself by being able to access the power switches without having to lift the cushions. The inlet plumbing may seem to be a bit technical, but is really simple.

The 240 volt proved very efficient with piping hot water, and controlled by an internal thermostat. The location of the outlet beside the door made it very accessible to get water for washing up.

Our 12 volt system comprises of two 125 Watt BP solar panels, a PL20 regulator and two 120Ah AGM deep cycle batteries. The 12 volt power for the Duoetto is controlled by a switch (black) which turns the unit on and off when required. This have proved successful when stopped for morning tea or lunch turning the hot water on for 20 minutes. This meant the water was hot enough when we camped, eg to have a shower but not enough for washing the dishes. We used a portable shower and a bucket. We do not turn the unit on after 2pm while we were camping to conserve battery power for the evening.

The only times we were unable to use the Duoetto on 12 volt was when it was raining or very overcast days. We also have a Yamaha EF1000iS generator which heats the water in the Duoetto on 240 volt. This works extremely well and after 30 minutes the water is too hot to place your hand in the water.

We are able to wash the dishes and then have showers in the one heating. We are very happy with the Duoetto Hot Water System.

Brilliant little unit. With cheap solar power, and lightweight lithium batteries, you can now go ‘gas free’ in any camper or motorhome.

The Duetto Mk2 12v 10 litre water heater works amazingly well – as long as you have 30A of power to drive it! Dixi has 675w of solar power and a 300AH house battery, so – as long as you don’t want more than a few showers per day – there is more than enough without dipping below 75% of battery even in cold weather.

We have a bit of shiny tape under the switch on the DB – so we can see at a glance if it’s been turned off when not required, to conserve power.

It takes about 20 minutes to heat 10 litres of cold water to 60° in 12v mode. It can also run on 230v, in which case it takes about 5 minutes. Typically, when bush camping (which is basically all the time!) we turn it on at about 5pm as we start to cook dinner, then turn it off after showers and washing up all done before going to bed. There is still hot water to rinse the brekky dishes in the morning. Note that all hot water pipes are fully insulated with 10mm thick closed cell foam (the black soft stuff).

For the techies, the DB does not handle that current – the heater has its own stand alone circuit breaker rated to 35A. The circuit on the DB is just a relay to the unit’s internal 12v controller. In 230v mode you just plug the 3-pin straight in to a 10A outlet. It also has its own tempering valve, limiting output temperature to 55° so it’s kid safe. Still youchee hot though!

Would we recommend the Duetto Mk2? You betcha – it’s a little beauty!

Highly recommended.
