IP 33 Rated, Built to be outside

Keep warm, exhaust fume free

The Heatflow is built to handle whatever the outdoors throws its way. Leave it outside where it’s meant to be while it delivers a steady flow of clean, powerful heat wherever you need it. Unlike most diesel heaters, the Heatflow is purpose-built for outdoor use, eliminating many of the risks that come with bringing heat indoors.

12/24V DC and Mains AC Compatibility

Versatile Power Options

Power the Heatflow wherever you are. Running on 12V, 24V, or a mains connection, it’s ready to fire up and deliver reliable warmth in seconds. Campsites or workshops it doesn't matter.

Heat-shielded exhaust panel

Protect yourself and the surroundings

The Heatflow’s side-mounted exhaust is fitted with heat shielding to prevent accidental contact and burns. Its elevated exhaust outlet keeps hot gases away from the ground, reducing the risk of fires and protecting nearby wildlife. No need for make shift exhaust kits.

Chassis-reinforced carry handle

Easy to pack, easy to unpack

The Heatflow has a strong, centre-mounted handle that’s fixed directly to the internal chassis for reliable support. The handle makes it easy to lift, move, and position the unit, whether you’re setting up at a campsite, workshop, or job site. Its solid mounting ensures nothing comes loose, even with regular use.

Magnet mountable controller

A controller you can't lose

The wired controller gives you full control of your Heatflow from startup to shutdown. It tracks key information including temperature, altitude, timer settings, CO alarm status, and estimated fuel levels, so you always know how your system is performing. For added convenience, the Heatflow also comes with a Bluetooth remote and app compatibility, allowing you to adjust and monitor settings from your phone.

FAQS

How long will this Diesel heater run on a full tank?

On a full tank the Heatflow will run for an approximate 20 Hours. The Heatflow uses 0.25L per hour of diesel fuel.

How do I operate my Diesel Heater?

Using the included controller or available APP view our User guide for any further information

Do I have to keep my Diesel heater outdoors?

The HEATFLOW should only be operated in spaces with adequate ventilation, it's designed to be operated outdoors with rain resistance. For experienced DIY users, the HEATFLOW could be fitted elsewhere providing it has an adequate exhaust. Dismantling your HEATFLOW voids your warranty.

Can I move my HEATFLOW after it's been operating?

Your HEATFLOW can be moved after operation but it's important to keep the exhaust facing away from your body to avoid burns. Once air ducting has been removed after operation be careful not to press exposed heater to any person(s).

Can I move my HEATFLOW during operation?

We don't recommend moving the HEATFLOW during operation to ensure everything continues to run smoothly. However there is no issue repositioning it as long as safety precautions are taken to not touch hot-zones.

Do I need to worry about pressure build-up?

You do not need to worry about any pressure build-up within the HEATFLOW fuel tank thanks to the pressure-release fuel cap.

How do I secure my HEATFLOW outdoors?

Using the Chassis-reinforced D-Link visible a chain can be attached and connected to any other immovable object e.g. Car wheels or Tent poles.

How much fuel do I have left?

Just what I needed for my cottage hollidays, where there is limited freezer space. The box is reasonably quiet, but you wouldn't want it in the bedroom.
I love the Bluetooth interface. Its very simple to operate, and responds very quickly.
