45 MINUTES ON MAINS, 2.5 HOURS ON 12V

1000W on 240V against 300W on 12V. Heat on mains when hooked up and save the battery.

10L READY, NOT ON DEMAND

Stored and held at temperature, so hot water is there the moment you open the tap.

RUNS ON 12V OR 240V

Detects the supply and switches on its own. Nothing to change over when you plug into mains.

OVER-TEMP AND DRY RUN PROTECTED

Both built in, with a pressure relief and non-return valve supplied. Tank rated to 117 psi.

BUILT TO LAST THE DUTY

Enamel lined steel tank on a single weld line, with an Incoloy 840 element chosen for service life.

The Duoetto MK2 gives you 10 litres of stored hot water that is ready when you are, rather than the wait you get from an instantaneous system. It suits caravans, RVs, camper trailers, horse floats, food vans and under-sink use at home, and it is fully compatible with the EGON Water Hub.

What makes it practical for touring is that it runs on either supply and works out which one it has on its own. On 240V it draws 4.2A and puts 1000W into the tank, taking about 45 minutes to reach 70°C, with a thermostat adjustable from 30°C to 75°C. On 12V it draws 25A for 300W and takes about 2.5 hours to the same temperature. That is why the usual pattern is to heat on mains whenever you are hooked up and keep 12V for when you are not.

Worth planning for: at 25A over 2.5 hours, heating a full tank from cold on 12V costs you roughly 60 amp hours. That is a serious chunk of most battery banks, so it is well worth sizing your battery and charging around it rather than discovering it on the first night away.

The tank is SPCC steel with an enamel lining for corrosion resistance, built on a single weld line, wrapped in polyurethane insulation to hold heat once it is up to temperature, and rated to 117 PSI. The element is Incoloy 840, chosen for service life in exactly this kind of duty. Over-temperature and dry-run protection are both built in, and a combination pressure relief and non-return valve is supplied. The whole unit is 7.4kg empty and 409 x 262 x 267mm, and mounts on a wall or on the floor to suit the space you have.

  • Automatic voltage detection, switching between 12V and 240V without you doing anything
  • Digital temperature control, adjustable 30 to 75 degrees C on 240V and up to 70 degrees C on 12V
  • SPCC steel and enamel tank for corrosion resistance, built on a single weld line
  • Polyurethane insulation to hold heat once the tank is up to temperature
  • Incoloy 840 heating element for long service life
  • Over temperature and dry run protection
  • Combination pressure relief and non-return valve supplied
  • Durable outer casing with service and inspection points
  • Wall or floor mounting to suit the space available
  • Fully compatible with the EGON Water Hub

  • Mounts on a wall or on the floor, so it can go wherever the space allows.
  • Allow for the filled weight, not the empty one. It is 7.4kg dry and around 17.4kg with 10 litres in it, so the mounting surface and fixings need to suit.
  • The combination pressure relief and non-return valve supplied must be fitted. The tank is rated to 117 psi.
  • On 12V it draws 25A while heating, so size the cable and fusing for that load rather than for the average.
  • All 240V connections must be carried out by a licensed electrician and comply with the relevant standards.
  • Never run the unit dry. Fill and purge air from the tank before switching it on, even though dry run protection is fitted.
Suitable for RVs, caravans, horse floats, food vans, and home under-sink applications.

Q: How long does it take to heat up?
A: About 45 minutes to reach 70 degrees C on 240V, and about 2.5 hours on 12V. The difference is simply power - 1000W on mains against 300W on 12V.

Q: How much battery does it use on 12V?
A: It draws 25A the whole time the element is on, so heating a tank from cold takes roughly 60 amp hours. That is a serious chunk of a typical battery bank, and it makes this one of the largest single loads a touring setup will place on a battery outside of an inverter. Heat on mains where you can, or run it while the vehicle is charging.

Q: Should I heat on 12V or 240V?
A: Use 240V whenever you are hooked up. It heats in roughly a third of the time and costs you nothing from the battery. Keep 12V for when there is no mains available.

Q: Do I have to switch it between 12V and 240V?
A: No. It detects which supply is present and switches automatically.

Q: How hot will it get?
A: The thermostat is adjustable from 30 to 75 degrees C on 240V, and up to 70 degrees C on 12V. Running it lower than maximum uses less power and still gives plenty of hot water for showering and washing up.

Q: Where can I mount it?
A: On a wall or on the floor. Size the mounting for the filled weight of around 17.4kg rather than the 7.4kg empty weight.

Q: What safety protection does it have?
A: Over temperature protection, dry run protection, and a combination pressure relief and non-return valve supplied with the unit. The tank is rated to 117 PSI.

Q: Will it work with the EGON Water Hub?
A: Yes, it is fully compatible and the two are commonly fitted together.

Q: What is the tank made from?
A: SPCC steel with an enamel lining for corrosion resistance, built on a single weld line, with polyurethane insulation around it and an Incoloy 840 element inside.

Q: Can I use it at home as well?
A: Yes. As well as caravans, RVs, horse floats and food vans, it is commonly fitted under a sink at home where a full size system is not needed.
