Highlights

All CombiNeo heaters are made in Germany and therefore represent the highest quality and reliability.

A new era of heating.

Experience maximum warmth and comfort when travelling with the CombiNeo – our newest 2in1 heater. The innovative CombiNeo instant water heater enables a supply of endless* hot water after a heating time of 8 minutes in gas or hybrid mode. Hot water is ready for washing up or rinsing your hands after just 3 minutes. This short waiting time maximises comfort and increases spontaneity when traveling. Whether in a caravan or motor home, the CombiNeo makes tedious advance planning a thing of the past.

The CombiNeo also impresses in heating mode: The improved combustion technology and high-performance warm air ventilation boost the heating power and thermal efficiency. This ensures efficient and rapid heating of the living area, which is particularly noticeable when heating up your camping vehicle for the first time in the cold season as it quickly provides cosy warmth. These advantages apply equally to motor homes and caravans.

The CombiNeo can be operated with both gas and electricity. In gas-only mode, the CombiNeo delivers 4.4 or 6 kW, while the high-performance electric option enables 1, 2 or 3 kW.
The CombiNeo can be controlled using the intuitive iNet X System. This includes an operator panel installed in the vehicle as well as an app.

For years, our Combi heaters have been the most popular heaters in the caravanning industry1. The CombiNeo continues the success story of our proven 2in1 combination heaters.
