Photovoltaic Caravan Boiler (10L) Fothermo

A hot shower in your caravan—anytime, anywhere. Enjoy more independence, more freedom, and more comfort! The photovoltaic caravan boiler offers the ideal solution for a reliable and sustainable way to heat water in your caravan. Once installed, the boiler produces free hot water for years to come—powered solely by the sun. The 10-liter Caravan Boiler is ideal for RVs, caravans, or even self-built campers—anywhere hot water is needed in mobile applications.

Connect the photovoltaic module directly to the boiler:
Up to 1,500 Wp of photovoltaic power can be connected to the boiler. The MPP tracker already integrated into the boiler ensures that as much energy as possible from the sun is converted into heat within the boiler. To put the boiler into operation, simply connect the photovoltaic modules to the boiler. No additional devices—such as charge controllers, MPP trackers, inverters, or other equipment—are required.

Details

• More Freedom:
  • A hot shower after an eventful day of hiking or sightseeing in the city makes traveling much more enjoyable. The photovoltaic water heater warms up during the day, so you can enjoy a hot shower immediately upon returning to your RV.
• More independence:
  • The photovoltaic water heater runs exclusively on electricity. This electricity comes either directly from the photovoltaic module or from a battery. The annual gas inspection by the TÜV, the regular purchase of new gas cylinders, or refueling with diesel for hot water are now a thing of the past. The photovoltaic water heater produces hot water for free and independently of fossil fuels.
• Renewable hot water production:
  • Utilize photovoltaic electricity. Direct connection of up to 1,500 Wp of photovoltaic power.
• Smart battery operation:
  • Use excess energy from a 12V or 24V battery to heat the water.
• Anti-freeze:
  • Easy drainage of water possible in winter.
• Made in Germany:
  • All water heaters are developed and manufactured in Germany.
• No fossil fuels:
  • The smell of gas or exhaust fumes during hot water heating are now a thing of the past!
• Specially designed for caravans:
  • Innovative technologies and intelligent algorithms for maximum comfort.
• Flexible installation:
  • The water heater can be installed either horizontally on a base plate or vertically on a wall.
