Fothermo Photovoltaic Caravan Water Heater boiler - 10 Litres

Vertical and horizontal installation of the boiler possible!

A hot shower in the caravan. At any time in any place. Enjoy more independence, more freedom and more comfort!

The photovoltaic caravan boiler offers the ideal solution for a reliable and sustainable way to heat hot water in the caravan. Once installed, the boiler produces free hot water for years. Just by the power of the sun.

The 10 litre Caravan Boiler is ideal for motorhomes, caravans or self-built campers. Just everywhere where hot water is needed in mobile applications.

Product Highlights

Photovoltaic - Hot water via free photovoltaic electricity
Battery operation - Use of surplus energy from a 12 V or 24 V battery to heat the water
Easy installation - Only the connection of 2 cables is necessary
Renewable hot water - 100% renewable hot water supply through the power of the sun.
No fossil fuels - Gas smell or exhaust fumes during water heating are a thing of the past
Anti-freeze - Easy draining of the water in winter
Flexible assembly - The boiler can be installed horizontally or vertically

Photovoltaic or battery? Both are possible!

Decide whether to connect the boiler to a photovoltaic module or the on-board battery of your caravan.
You can connect up to 1500 Wp of photovoltaic power to the boiler. It does not matter whether you use large or small, thick or thin, flexible or rigid photovoltaic modules.
Or use excess power from the battery and store it in the boiler – as hot water.

Easy connection due to two open cable ends.

The connection of the Caravan Boiler is simple, intuitive and done after a few moments.
Plus to plus and minus to minus. That’s all you need to pay attention to when connecting. A degree in electrical engineering is certainly not required for this!
An integrated reverse polarity protection provides additional security, if something should go wrong.

Automatic heating. Finally, no more waiting.

As soon as the sun rises, the heating process begins. Fully automatic and all day.
Once you return from your hike or stroll out of town, a hot shower is immediately ready for you.
The boiler does not have to be turned on extra to take a shower an hour later. These times are now over.

Mounting made easy. With only four screws.

Mount the boiler in your camper with only four screws. More than a screwdriver you do not need.
The assembly is simple and safe.

Use surplus energy from your existing 12 V or 24 V on-board battery.

First the battery is charged. Once the battery is fully charged, the photovoltaic boiler turns on automatically. It takes the excess energy and converts it into heat.
The battery can still be charged via photovoltaic modules, the alternator or, for example, via mains power.
Any 12V or 24V lead or LiFePO4 battery can be connected to the boiler.

Save expensive battery storage! Use boiler as energy storage.

The photovoltaic boiler acts as an extended energy storage. You can store the excess energy cheaply in heat, instead of expensively in an additional battery.
580 Wh are needed to heat the water once from 15 °C to 65 °C. From now on, you no longer need to store this energy in a battery.
The boiler takes all the energy surplus as soon as the battery is fully charged. It is in other words a battery extension.

Innovative and intelligent algorithms for even better performance.

Choose from 5 individual modes to optimally adapt your boiler to your existing energy system in the camper.
Algorithms measure the excess energy of your battery and convert exactly this amount into heat. Everything works fully automatically.
Discharge your on-board battery to get even more hot water. But only if you want to! Otherwise, only the surplus will be used.

Up to 25 litres of hot water for showering.

The photovoltaic caravan boiler heats water up to 65°C. Then it switches off automatically.
For showering, the hot water is mixed with colder water in a standard shower fitting.
Up to 25 litres at 35 °C water temperature can be used. With low-flow shower head, this is also easily enough for 2 people.

Two digital displays provide maximum insight.

Directly at the boiler, the actual water temperature, the heat output and the sum of all energy quantities ever fed in can be read.
A second display with 5 meters cable length allows the temperature display from anywhere in the caravan.
A small rechargeable battery in the boiler ensures that the display can also be read at night.

Horizontal or vertical mounting? That works both ways!

Innovative heating elements provide optimal heat generation in both vertical and horizontal mounting.
Space-saving installation possible due to individual mounting.

More comfort? Make yourself comfortable!

The photovoltaic boiler provides hot water all by itself. Once installed, it will heat the water for you.
After an eventful day back at the caravan, a hot shower is immediately ready for you.
