Warm shower kit 2.0 for Autoterm Air 2D / 4D

Warm shower kit 2.0 - Autoterm parking heater + combiBOIL with Comfort Boiler Control

The original from tigerexped - but now even better!

The Warm Shower Kit is the simple way to equip touring vehicles or boats & yachts with a hot air heater and hot water at the same time. In contrast to technically complex combination devices, the kit consisting of two individual devices is less expensive and, above all, less prone to complete failure. And if necessary, it can even be repaired while traveling.

The strength of the Warmduscher kit is that it is simple and the two main elements (heater and boiler) function separately. Defects in one component do not automatically affect the other. A defect in the boiler is unlikely due to the high quality of materials and workmanship with high pressure resistance - however, should damage occur for whatever reason, the heater will continue to run completely unimpressed and that is a good thing. Because not being able to take a hot shower is one thing - spending the night in a completely chilled vehicle at perhaps -20 degrees is another.

The Warm Shower Kit 2.0 is therefore a system that is simple to set up and easy to install. It is therefore perfect for DIY enthusiasts, but of course also for professional manufacturers who want to offer their customers a low-maintenance, trouble-free solution for their trips.

How does the Warm Shower Kit 2.0 work:
The Warm Shower Kit 2.0 can generate hot water in three different ways:

Via an electric heating element, which means via electricity if you have just enough reserves, or are connected to shore power.
Simply on the side when the heating is running - without consuming any additional energy. Hot water is the "waste product", so to speak.
NEW: The boiler can be integrated into the engine's cooling water circuit to heat either the service water itself or a second water loop. Conversely, the engine can also be preheated to make starting more gentle (not suitable for use in arctic temperature ranges).
Each of these three options has its advantages and can be used when it suits best. After a few days of self-sufficient camping in hot weather, for example, you don't want to leave the heating on, nor do you want to heat up the water from driving. However, if it is too warm for the heating, there is probably enough solar power in the batteries to generate hot water via the electric heating element.

• With the combination of three options, this kit always offers the one that fits perfectly in every situation.

The options for integration into the cooling water circuit are as follows:

Cooling water circuit heats the service water, i.e. the cooling water circuit is connected to the boiler and heats service water for showers etc. while driving. (Caution: As the temperature of the cooling water can rise above 100°C (due to pressure), the boiler must be prevented from overheating by means of a valve or by switching off the circulation pump).
The boiler preheats the cooling water circuit (engine), which means that the above function is reversed. The engine cooling circuit can be preheated by connecting the boiler to a 230V/110V power source or by using hot air from the parking heater.
Heating a second water loop, whereby the energy that is fed into the boiler via the electric heating element or hot air is fed into a second water circuit via a circulation pump. It is also possible to combine the two water circuits (so that the cooling water circuit heats the second water loop), although precautions must be taken with regard to the flow temperature from the motor.

NEW: Integration of a second water loop
With combiBOIL it is possible to operate a second water loop with hot water. For example, underfloor heating or towel radiators can be implemented to make it easier to dry wet clothes and towels in the vehicle.

Please note that an expansion tank must be integrated into the water loop and, depending on the application, the water may need to be circulated by a circulation pump.

Scope of delivery:
The Warm Shower Kit 2.0 consists of two main components (heater and boiler) and material to connect and install them to create a perfectly functioning system.
