Dometic Heki Midi Roof Vent with Blind & Fly Screen

The Dometic Heki Midi is the mid-size Heki roof vent – a 700mm x 500mm opening that provides excellent natural light and ventilation in a more compact footprint than the full Heki 2. It comes complete with an integrated roller blind and fly screen, a double acrylic-glazed dome, and built-in LED lighting with white daylight and blue night-time modes.

How do I know this will fit my caravan?
Check the 700mm x 500mm cut-out size against your existing roof opening (or the space you plan to cut), and confirm your roof thickness falls within the 25–60mm range, as the correct mounting bracket kit depends on thickness. Let us know your roof thickness when ordering so we can supply the matching bracket kit, or contact us first if you're unsure.

What's the warranty?
Dometic Heki vents typically carry a 12-month manufacturer's warranty. Contact us for full warranty terms and to arrange a claim if needed.

Do I need a professional to install a Heki roof vent?
Installation requires cutting a hole in the caravan roof and sealing around the vent frame. This is a job most experienced DIY caravanners undertake themselves, but it must be done correctly to avoid leaks. Our workshop can install this for you – contact us to book.

Is the Heki Midi suitable for New Zealand's variable weather?
Yes. Heki vents are designed for demanding European conditions and hold up well to New Zealand's sun, rain and hail. The raised dome allows ventilation even in light rain, but the vent should be closed fully in heavy rain or high winds, and always while towing or driving.

What do the LED lights do?
The built-in LED lighting has a white setting for everyday daytime use and a dimmer blue night-light mode, so you don't need to disturb the whole caravan for a quick light at night.
