Q: How long does a Truma heater installation take?

A: Yes. Old Truma or Trumatic systems can often be replaced with modern Combi or VarioHeat units, improving efficiency, performance and parts availability.

A: When correctly installed and maintained, Truma systems have sealed combustion, safety shut-offs and temperature controls that make overnight use part of their intended operation.


Q: Can you fix Truma error codes and control panel issues?
A: Yes. Diagnostic equipment and experience with Truma control systems allow most error codes to be traced and resolved, whether the fault lies with the heater, sensors or wiring. We repair Truma heaters in the North West and North Wales area.
