Diesel heaters

Diesel heaters

Stay warm wherever you travel

Keep your van cosy all year with a professionally installed diesel heater. At Vanlifer, we install and service 12 V diesel air heaters from trusted brands Autoterm (Planar NZ), Dieselheat Australia, and Truma NZ. Every system is fitted to meet New Zealand’s Green Warrant self-containment and safety standards.

Why choose a diesel heater?

Diesel heaters are the most efficient and reliable way to stay warm when freedom camping or travelling off-grid. They use very little fuel, produce dry heat, and run quietly without draining your batteries. A diesel heater turns your campervan into a true four-season home on wheels.

People are asking

Can it run off a solar setup?

Yes. As long as your solar feeds a 12V or 24V battery system, you’re good.

How much power does this fridge freezer use?

On 12V it draws around 2.5–5 A depending on temperature settings and ambient conditions. It’s built to be energy-efficient for off-grid living.

Can I control the temperature while I’m on the road?

Yes, there’s a Bluetooth app for easy temperature control straight from your phone.
