Combi Heating Element Aftermarket Replacement Pair — 390mm

Restore electric heating performance without replacing the whole unit.

If your Truma Combi heater has stopped producing hot water on electric, heats slowly, or shows weak electric heating performance, failed or worn heating elements may be the cause. In many cases, the heater still runs, but the electric heating side becomes slow, inconsistent or ineffective.

This 390mm aftermarket replacement element pair gives you a direct-fit repair option for selected Combi E heaters where the 390mm element specification is required.

Built with anti-hotspot technology, our stainless steel heating elements are designed to spread heat evenly. Inside, a heating coil is packed in magnesium oxide, helping transfer heat efficiently while keeping the element electrically insulated and safe.

Direct-Fit Aftermarket Replacement

These are direct-fit aftermarket replacement elements for selected Truma Combi 2E, 4E, 6E, D4E and D6E heaters.

They are designed to match the correct 390mm specification for compatible models and help restore dependable electric heating and hot water performance when failed elements are the issue.

This listing includes the elements only. If you also need grommets, choose our separate element-and-grommet set.

Why the Correct 390mm Length Matters

Correct element length is essential for fitment, positioning and reliable operation.

Some wrong-spec listings use 410mm elements. These are not a like-for-like substitute for the listed compatible Combi models and may create fitment, positioning or performance issues.

This element pair uses the 390mm length required for compatible models, helping provide:

• Accurate fitment when matched to the correct heater
• Correct positioning inside the heater
• Reliable electric heating performance
• No modification when fitted to the correct compatible model

Always check your heater model, existing element length, part reference and fitting details before purchase.

Compatible With Selected Truma Combi Heaters

This 390mm aftermarket heating element pair is compatible with selected:

• Truma Combi 2E
• Truma Combi 4E
• Truma Combi 6E

Please confirm your model before ordering. The manufacturer label on the heater body will show whether your unit is a 2E, 4E, 6E, D4E or D6E model.

Suitable for Motorhome and Caravan Repairs

This element pair is suitable for motorhome and caravan heating repairs where the existing 390mm electric elements have failed and the full heat exchanger assembly does not need replacing.

FAQs

Does this listing include grommets?

No. This listing includes the heating elements only. If you need grommets, choose the separate listing that includes grommets with elements.

Are these genuine Truma parts?

No. These are aftermarket replacement parts. They are not genuine/OEM Truma parts, and Truma does not supply, endorse or approve them.

Which heaters are these elements compatible with?

They are compatible with selected Truma Combi 2E, 4E, 6E, D4E, and D6E heaters where the 390mm element specification is required.

Why does the 390mm length matter?

The correct length helps ensure proper fitment and positioning inside compatible heaters. Wrong-length elements are not a like-for-like substitute and may cause fitment, performance or reliability issues.

Do I need the full heat exchanger kit instead?

Not always. If only the electric heating elements have failed, an elements-only repair may be suitable. If the full heat exchanger assembly has failed, choose the correct genuine heat exchanger kit instead.

Buy the correct 390mm aftermarket replacement element pair and restore electric heating performance in your compatible Combi heater.
