Black Friday Portable Diesel Heaters

Winter brings plenty of opportunities to get outdoors, although keeping warm can become a challenge when the temperature starts to drop.

The HEATFLOW Portable Diesel Heater makes spending time outdoors more comfortable. Designed to operate outside your living space, it delivers warm air through a reinforced heat duct that can be directed into your tent, awning, bivvy or workspace.

With 12V and mains power compatibility, HEATFLOW can be used across a wide range of setups. Its portable design also means you can move it between locations, making it a useful addition to your camping equipment, fishing gear or workshop.

Diesel Heaters for Camping and Tents

Winter camping has its own appeal. Quieter campsites, crisp mornings and the chance to enjoy the outdoors without the summer crowds. Of course, once the sun goes down, temperatures can fall pretty quickly.

A portable diesel heater for camping helps keep your tent comfortable throughout those colder evenings and mornings.

HEATFLOW operates outside your tent, with warm air fed inside through the supplied heat ducting. You can settle down for the evening, get comfortable and enjoy a bit of warmth after spending the day outdoors.

Whether you're heading away for a weekend or planning a longer trip during the winter months, HEATFLOW is a practical addition to your camping setup.

Diesel Heaters for Caravan and Motorhome Awnings

Your awning can make a big difference to the amount of space you have when you're away in your caravan or motorhome. It's somewhere to sit, eat, store your equipment or simply relax after a day out.

During the colder months, though, that extra space can become pretty chilly.

With a diesel heater for caravan awnings, you can keep warm air flowing into your awning and make better use of the space throughout autumn and winter.

HEATFLOW sits outside the awning and directs heated air inside through its ducting. It's ideal for those colder evenings on the campsite, early morning coffees or simply spending a bit more time relaxing.

For anyone who enjoys touring throughout the year, having a portable source of heating can make those winter trips much more comfortable.

Diesel Heaters for Roof Tents and Overlanding

There's something special about heading off in your 4x4, finding somewhere to camp and waking up surrounded by the countryside.

When you're sleeping in a roof tent during the colder months, though, keeping warm becomes an important part of planning your trip.

A diesel heater for roof tents helps make those cold nights and early mornings more comfortable.

HEATFLOW can be positioned outside your roof tent, delivering heated air into your sleeping area through its ducting. Its portable construction makes it easy to take along on overlanding trips, while the different power options give you flexibility when planning your setup.

From weekend trips in the countryside to longer overlanding adventures, HEATFLOW helps you enjoy camping throughout the colder seasons.

Diesel Heaters for Fishing Bivvies

Anyone who spends time fishing through winter knows how cold it can get on the bank. Long nights, damp conditions and hours spent sitting still can leave you feeling the chill pretty quickly.

Having a warm bivvy makes those sessions a lot more comfortable.

The HEATFLOW diesel heater for fishing bivvies is designed to deliver warm air into your shelter while the heater itself remains outdoors.

Set the heater up outside your bivvy, position the ducting appropriately and enjoy a steady supply of warm air inside.

It's a particularly useful piece of equipment for carp anglers spending several nights on the bank, especially during autumn and winter when temperatures can drop considerably overnight.

A warmer bivvy gives you somewhere comfortable to retreat to between bites, have a brew and settle in for the night.

Diesel Heaters for Sheds, Garages and Workshops

Spending time in a cold workshop isn't particularly enjoyable, especially when you're trying to concentrate on a job or work with your hands.

During winter, sheds and garages can become uncomfortable places to spend any length of time.

A portable diesel heater for sheds and workshops gives you a way to introduce warm air into your working space, helping you stay comfortable while you get on with the job.

HEATFLOW can be positioned outside the building, with warm air directed inside through a suitable ducting arrangement.

Whether you're working on your car, carrying out repairs, tackling a DIY project or spending a few hours in your garden workshop, having a source of heating can make a noticeable difference.

Its portable design is also useful if you regularly work in different locations and need a heater you can take with you.

Diesel Heaters for Campervans and Van Life

Travelling in a campervan during autumn and winter can be a great experience. Campsites are often quieter, popular destinations are less crowded and there's plenty to enjoy during the colder seasons.

Of course, keeping your van comfortable overnight takes a little more planning.

A portable diesel heater for campervans provides a practical way to introduce warm air into your vehicle while you're parked up.

HEATFLOW is designed to operate outside the campervan, with heated air delivered inside through its ducting. This makes it an option for campervan owners who want portable heating that can be used across different setups.

Whether you're spending a weekend away or heading off on a longer winter road trip, HEATFLOW helps make those chilly mornings and evenings more comfortable.
