Webasto EHM900W Electric Heat Module for A6/A9 Air Handlers – 900W 230V

Cabins fitted with the mid-sized A6 or A9 air handlers get their heating accessory match in the Webasto EHM900W, a 900-watt electric heat module that installs in-line into the air duct and connects directly to A-Series electronics with no separate controls needed. This a6 a9 air handler heating accessory scales up from the smaller EHM600W to serve handlers with genuinely higher heat demand.

The practical benefit compounds with cabin size: a larger air handler moving more air needs proportionally more heat capacity to bring that airflow up to comfortable temperature, and this module’s 900W output is sized specifically to match the A6 and A9 handlers rather than being underpowered for the airflow it’s heating.

Why Choose the Webasto EHM900W

This unit carries Webasto’s standard 2-year warranty. Given the compatibility contradiction identified above between the page’s intro text and its own specification table, confirming the correct handler match (A6/A9, not A4) with Webasto or CTM before ordering is essential to avoid purchasing the wrong capacity module.

What to Know Before Installing

• Confirm compatibility against the A6/A9 handler models specifically, not the A4, given the contradiction on this listing noted above
• A flow control valve must also be fitted when using this module — it does not work as a standalone installation
• Comes preinsulated to prevent exterior condensation, with 2 stainless steel mounting brackets included for wall mounting
• Current draw (4A) should be factored into your cabin’s electrical circuit planning alongside the air handler itself
