Hot Shower Upgrade Kit 2.0 - combiBOIL with Comfort Boiler Control Panel

Hot Shower Upgrade Kit 2.0

This upgrade kit turns your existing air heater into an integrated heating and hot water system.

It includes all the necessary connecting parts between the heater and boiler, as well as all the components you will need for their installation.
 

All information about the complete system "Hot Shower Kit 2.0":

The Hot Shower Kit has been the easiest and most popular way to equip travel vehicles or boats and yachts with a warm air heater and hot water since our development in 2017.

Unlike technically complex combination devices, the kit is made up of two individual devices, which is more affordable and less prone to failures. If necessary, it can even be repaired on the road.

The strength of the Hot Shower Kit lies in its simplicity and the fact that the two main components (heater and boiler) function independently. Defects in one component do not automatically affect the other. A defect in the boiler is unlikely due to its high material and processing quality with high pressure resistance - however, if a damage does occur, for whatever reason, the heater will continue to run completely unaffected, which is great. Because not being able to shower hot is one thing - spending the night in a vehicle that has cooled down completely at perhaps -20 degrees, that's something else.

The Hot Shower Kit 2.0 is therefore a simple, easy-to-assemble system. It is therefore perfect for do-it-yourselfers, but of course also for professional manufacturers who want to offer their customers a low-maintenance and maintenance-friendly solution for their travels.
 

Hot Shower Kit 2.0 - UPGRADE 2023

The original Hot Shower Kit is now equipped with the combiBOIL hot water boiler. This upgrade makes hot water production even more versatile, comfortable and safe.

Choose the right one for your project

The Hot Shower Upgrade Kit 2.0 is available with the combiBOIL hot water boiler in various versions and three sizes.

Please note: Especially if your heater is already installed, pay attention when selecting the volume, not only to how much water you want to heat, but also to how much space you really have left in the camper to install the Boiler (it should be mounted in a preferably straight line and not far from the heater).

Your current configuration will be displayed in the product title and drop-down menu.

Scope of delivery:

• 1x combiBOIL hot water boiler with 7, 9 or 12l capacity, with stainless steel tank and heat exchanger, in the variant selected above and with Comfort Boiler Control control unit if selected accordingly.
• Comfort Boiler Control Panel
• 2 x adapters for the hot air connections of the Boiler
• 1x adjustable thermo-mixing valve / anti-scalding protection
• 2 x brass hoses
• 1 x screw-on hose connector
• 2 x T-piece for water line
• 1 x steel flex hose G1/2" for the heat-resistant connection between boiler and mixer
  
   

Additionally Required for Your Installation (depending on your project)

Every vehicle is different, so some things cannot simply be included in the package. Depending on the situation, installation location, etc., you'll need to select what's suitable for your specific land or water vehicle.
 

Heater Mount / Installation Flange

The heater can be installed without a mount, but this is more complex and comes with the risk that the hole pattern might not match precisely, creating tensions or inadequate heat dissipation. Therefore, it's generally advisable to use a mount or our installation flange, which simultaneously simplifies the installation process and provides good thermal isolation.

Mounts are available in different designs for various floor thicknesses or for installing the heater in a box. For the Hot Shower Kit, a mount like this one is typically used. However, in the Heater Accessories section, you can also find mounts for other special applications.
 

Water Hoses

Similar to mounts, the situation with hose lines in the water system is individual for every vehicle. Calculate the length of both hot and cold water hoses once you've determined the installation positions for the heater, boiler, and all other water system components, and order accordingly.

Important:
If the water is intended for drinking or cooking, we strongly recommend looking for the appropriate certification of the hoses. This ensures that no harmful substances transfer to the drinking water and that the material does not alter the taste and composition of the water.

Drinking water-certified hose lines are available here for both hot and cold water.

In our range, you'll also find water filters for disinfection and safe drinking water consumption at any destination. For help in choosing the right filter, take a look at our online magazine's filter selection guide (German language only by now).
 

Pressure Regulator

Our boiler tank is made of high-quality stainless steel and is precisely crafted. However, the input pressure should be limited to 1.5 bar.

In all pressurized water systems, as well as systems with immersion pumps with built-in or separate check valves, a pressure regulator should definitely be used in front of the boiler. It should be set to 1 to 1.5 bar. You can find pressure regulators with a pressure gauge or without pressure gauge under the following links.

By the way, the Warm Shower Kit 2.0 comes with a built-in safety valve that releases excess pressure, so there's no need to purchase it separately.
 

Water Pump

A decent pump provides the necessary pressure and circulation in the system. It must be strong enough to ensure good and even flow even when water is being filtered, allowing for a smooth operation of the water system. Longevity and reparability are also important factors. You can get this pump and a suitable accumulator tank to make the pressure water system even smoother and calmer as a bundle at a discounted price.
