Thermo Technica Diesel & Electric Combi Heater D6E – Bare Bones Kit (2026 Model)

Upgrade your motorhome with a powerful and efficient alternative to your existing Truma Combi D4E or D6E. The Thermo Technica Diesel & Electric Combi Heater D6E delivers reliable heating and hot water, while improving on performance, durability, and value.

Instead of replacing like-for-like, upgrade to a modern diesel combi heater built for real-world travel.

Designed as a direct retrofit for Truma D6E systems, this unit fits into your existing setup with minimal modification. As a result, you can upgrade quickly without the cost of a full system overhaul.

Why Upgrade to Thermo Technica?

We built this system for motorhome users who expect more. After dealing with overpriced and outdated heaters, we created a better alternative.

As a result, this motorhome heating system offers:

  • Better fuel efficiency
  • Faster heating performance
  • Modern Bluetooth control
  • Stronger, longer-lasting build quality

Control Your Heating Anywhere

Take full control wherever you travel. Every Thermo Technica combi heater includes built-in Bluetooth connectivity.

Simply connect using:

  • Android (APK app)
  • Apple (MyBluee app)

Whether you’re off-grid or relaxing inside your van, you can adjust your heating instantly. In addition, backwards compatibility allows older systems to benefit from smart control.

Faster Heat. Better Efficiency.

We redesigned this diesel-and-electric combi heater from the ground up. Instead of minor tweaks, we upgraded the components that matter most.

Improved sensors and motor performance deliver:

  • Faster heat-up times
  • Quieter operation
  • Reduced diesel consumption

As a result, you get consistent cabin heat and hot water without long wait times.

Built to Handle the Road

Motorhome travel puts your system under constant stress. That’s why we use durable metal construction instead of plastic.

So, whether you’re driving long distances or exploring off-grid locations, this diesel combi heater is built to last.

What’s Included in the Bare Bones Kit

This kit includes essential components as an alternative replacement for a Truma combi:

  • Diesel and electric combi heater unit

Cable lengths are:

  • Diesel line and cable – both 5.5m

In most cases, you can reuse your existing ducting and installation parts. Therefore, installation stays simple and cost-effective.
