For brand new installations we suggest using the Domestic water kit (Assy: AT7-0018-CB) for optimal performance. If installing the boiler in an existing system, keep in mind that the system pressure is not allowed to exceed 1.5 bar. If it does, make sure to use a Pressure reducer (Assy: AT7-0006-FF0) to avoid leaks or damage to the water system components.

The AUTOTERM duoBOIL 9L is capable of heating up and storing 9 liters of hot water, which is usually enough for four adults to take consecutive showers.

Provides both on-land and marine vehicles with a constant hot water flow, allowing to travel, without having to worry about the comfort of hot showers or warm domestic water.

It seamlessly integrates with AUTOTERM Liquid heater installations, making it an easy upgrade for existing AUTOTERM users. It can also heat water using hot engine coolant and function independently, powered by electricity.

Recommendations for the smoothest user experience

Domestic Water Kit

A domestic water heating kit to make the duoBOIL installation as easy and efficient as possible. It includes a Pressure tank (1pce), Inlet filter (1pce), 1/2'' to 10mm connectors (3pcs), Hose T-pieces 10x10x10 (2pcs), Hose connector 10mm (1pce), Spring clamps 15,7-16.5mm (18pcs), Male brass hose adapters 1/2' to 10mm (5pcs).

Water Pump

Ensures water circulation. If you already have a pressure water pump in your vehicle, you don’t need to replace it to use with the boiler system.

Pressure Reducer

Eliminates risks of an overpressurized domestic water system, that could cause leaks.

Thermostatic mixing valve

Mixes hot and cold water to ensure optimal temperature and extend the warm water volume.
