Truma Heating, Hot Water & Air Conditioning Installation, Servicing, Diagnostics & Repairs
​
At a glance
Truma heating and hot water systems provide blown-air heating and hot water in caravans and motorhomes. To operate safely and reliably, Truma systems require regular servicing, correct electrical and gas checks, and accurate fault diagnosis.
At KamperBitz, Truma servicing and repairs are carried out by experienced, manufacturer-trained engineers using approved procedures and test equipment.
What Is a Truma Heating System?
Truma systems are blown-air heating units, often combined with hot water production, that distribute warm air through ducting around the vehicle. They are widely fitted to caravans, motorhomes and campervans due to their compact design and fast heat-up times.
Truma heaters can operate on:
-
Gas
-
230V electric
-
A combination of both
Because they rely on multiple systems working together, faults can sometimes appear in one mode but not the other.

Common Truma Problems We See
We regularly diagnose Truma issues such as:
-
Heater working on gas but not on electric
-
Heater shutting down after extended use
-
Tripping hook-up or RCD when on mains power
-
Error codes displayed on the control panel
-
Poor airflow or uneven heating
-
Water ingress damaging internal components
Early diagnosis often prevents expensive secondary damage.
Why Truma Servicing Is Important
Truma heaters combine gas, electrics, electronics and airflow in a compact unit. If one part isn’t operating correctly, it can affect the entire system.
Without proper servicing:
-
Electrical faults may go unnoticed
-
Gas components can deteriorate
-
Water ingress can damage PCBs
-
Heating efficiency and reliability suffer
Routine checks help maintain safety, performance and long-term reliability.
Who Carries Out Your Truma Work?
All Truma heating and hot water work is carried out by KamperBitz, an experienced leisure vehicle workshop working across:
-
Caravans
-
Motorhomes
-
Campervans
We use calibrated test equipment and follow correct diagnostic procedures. All findings are explained in plain English, with options discussed before any work is carried out.
Truma Heating & Habitation Checks
Truma heating systems are an important part of a habitation check.
During a habitation inspection, we assess:
-
Safe gas and electrical operation
-
Heater startup and shutdown behaviour
-
Ventilation and flue condition
-
Control panel operation
Any faults or safety concerns are highlighted clearly with recommended next steps.
Frequently Asked Questions
How often should a Truma heater be serviced?
Truma heaters should be inspected annually as part of a habitation check, with additional servicing or repairs carried out if faults are identified.
Why does my Truma heater work on gas but not electric?
This is commonly caused by a failed 230V heating element, wiring fault or control issue.
What causes Truma heaters to trip the electrics?
Common causes include faulty heating elements, water ingress onto components or wiring issues.
Can Truma heaters be repaired?
Yes. Many Truma faults can be repaired with correct diagnosis rather than full replacement.
Do you work on older Truma systems?
Yes. We diagnose and repair both older and newer Truma heating systems where parts availability allows.
When Should You Book Truma Heating Work?
You should book if:
-
Your heater shows error codes
-
Heating performance has dropped
-
The system trips your hook-up
-
It works on one power source but not the other
-
You’ve noticed unusual noises or smells
