Thermann support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I safely dissipate hydrogen gas if my Thermann water heater hasn't been used for weeks?

    Turn on a hot tap for several minutes at a sink or basin (not a dishwasher or washing machine). Do not smoke, use open flames, or operate electrical appliances nearby during this process.

  • Can I reset the over-temperature energy cut-out on my Thermann water heater myself?

    No, do not reset the over-temperature energy cut-out yourself. You must contact a licensed tradesperson for servicing to ensure safety.

  • How often should the PTR valve on a Thermann water heater be checked?

    The PTR Valve should be checked regularly by a licensed tradesperson, with replacement intervals not exceeding 5 years, or as dictated by local regulations.

  • What should I do if my Thermann heat pump unit displays an error code?

    Monitor the segmented display for the exact error code. Turn off the appliance at the electrical isolation switch and contact a qualified technician for repairs, as the system contains high-pressure refrigerant.
