(Save this. Screenshot it. Print it. This is your lifeline.)

Before Bed

Run your heater for 20 to 30 minutes
Close all curtains + install reflective window covers
Put a hot water bottle in your sleeping bag
Wear thermal base layers + wool socks + a beanie
Eat a warm meal
Keep a tiny opening (1 to 2 cm) on a window to reduce condensation

Your Bed Setup

Use flannel or thermal sheets
Add a down duvet + fleece blanket
Raise your mattress slightly to prevent cold transfer
Add insulation underneath your mattress

In the Morning

Run heater while preparing breakfast
Ventilate for 5 to 10 minutes to remove condensation

PART 1: If You’re Renting a Campervan (Indie Campers)

Renting simplifies everything, the hardest part (installing heating) is already solved. But to sleep warm, you need to understand what heating your vehicle has and how to use it properly.

1. Know Your Heating System (Essential for Comfort)

Indie Campers vehicles come with different heating setups depending on the model:

Option A – Water Heating (220V Boiler)

Works perfectly when connected to campsite power
Gives you hot showers and warm water
Not designed for continuous cabin heating

Option B – Water + Air Heating (TRUMA Gas or Diesel System)

Best for winter!
The TRUMA system provides:

Warm air circulation
Heated water
Low fuel consumption
Reliable temperature regulation
Dry heat → reduces condensation

Option C – Stationary Gas Air Heater

Efficient for heating the living area
Perfect for mild/mid-cold winter temperatures
Great for remote areas

Always check “Included Features” on your booking page to know your heating type.

2. Add a Portable 220V Fan Heater (Highly Recommended Extra)

Indie Campers lets you include a portable fan heater that is available at specific locations.

Why it’s useful:

Heats small spaces extremely fast
Great for evenings and mornings
Perfect at campsites with electric hookups
Extremely efficient

3. Insulate Your Windows: The #1 Heat Loss Point

Heat escapes through glass fast. Cover your windows with:

Magnetic or suction reflective covers
Thermal curtains
Windshield insulation

This alone can keep your camper 5 to 10°C warmer overnight.

4. Improve Your Bedding Setup

To sleep warm:

Use flannel sheets instead of cotton
Add microfleece or down duvets
Bring thermal blankets
Sleep in a winter-rated sleeping bag if temperatures are extreme
Wear a thermal hat (huge warmth gain)

Traveller tip:
“Two sleeping bags — one inside the other — feels like a cocoon and traps heat incredibly well.”

5. Eat a Hot Meal & Drink Something Warm Before Bed

Your core temperature matters more than your blankets.
Have: Soup, pasta, tea, hot chocolate

Heat some water and fill a hot water bottle, one of the most effective and affordable ways to stay warm in a campervan, widely recommended by experienced vanlifers.

6. Reduce Condensation (Staying Dry = Staying Warm)

At night:

Keep 1 to 2 cm ventilation
Avoid drying clothes inside
Leave wet boots outside the sleeping area
Wipe windows in the morning

Warm + humid air feels colder.

7. Choose the Right Parking Spot

Pick: Low wind areas, sheltered spots near trees, lower altitude zones

Avoid: Ridge lines, exposed cliffside parking, open coastline during storms

PART 2: If You Have Your Own Campervan (Van Owners)

Sleeping warm in your own van requires preparation. But you have more control, more options, and can build the perfect winter setup.

1. Upgrade Your Insulation (Most Important of All)

Insulate:

Walls
Ceiling
Floor
Doors
Cavities

Best materials:

PIR insulation boards
Recycled plastic insulation
Sheep wool (great moisture control)
Reflectix for windows

Traveller wisdom: “Memory foam gets rock hard in cold weather and holds the cold. Use a real mattress.”

Also: “Add airflow under your bed frame — stops condensation + mold.”

2. Choose the Best Heating System (Ranked)

Diesel Heater (Best Overall)

Cheap to run
Connects to fuel tank
Great heat output
Low noise
Works at altitude
Very reliable

Traveller advice: “Diesel heater. End of story.”

Truma Combi (Premium)

Heats:

The living area
The water

Fuel: gas, diesel or electricity.
Perfect for cold European conditions!

Propane Heaters (Mr. Buddy, Propex)

Pros:

Great heat
Affordable
Fast to warm up

Cons:

Requires ventilation
Must have a CO detector
Not ideal for tiny spaces overnight

Electric Fan Heater

Perfect if:

You’re connected to a campsite
You want quick, immediate warmth

Oil-Filled Radiator

Safe but:

Heavy
Slow
Needs 220V

Halogen Heater

Warm ambience, low energy but not strong enough alone.

3. Electricity & Battery Management in Winter (Critical Insight)

Cold temperatures reduce battery efficiency by 20 to 50%.
So in winter:

Avoid running heaters directly from your leisure battery
Charge daily through:
- Driving
- Solar (less efficient in winter)
- Campsite hookups
Turn off unused lights
Keep your inverter usage low
Warm your battery compartment if possible

Ideally keep your battery above 5°C.

4. Improve Window & Door Sealing

Use: Thermal curtains, reflective insulation, blackout insulated covers, magnetic DIY panels

Doors and windows = biggest heat leak!

5. Layer Your Bedding and Clothes

Wear: Merino wool base layers, thermal socks, fleece mid-layer, beanie.

Use: Down duvet, fleece blankets, hot water bottle, electric blanket (only with hookups).

6. Reduce Moisture — Your Worst Enemy

Moisture makes you feel colder.

Prevent: Ventilate, use dehumidifier bags, avoid cooking inside (if possible) and keep windows cracked slightly at night.

7. Winterize Your Van (For Sub-Zero Trips)

If temps drop below freezing:

Drain water tanks
Drain grey water
Empty water pump
Keep water containers inside
Add insulation around pipe areas

Frozen pipes = expensive repairs!

Troubleshooting: If You’re Still Cold, Check This

Window covers too thin → add Reflectix

Mattress too close to cold floor → add insulation or slats

Diesel heater shuts off → check battery levels or intake

Moisture → ventilate more / dry surfaces

Blankets not enough → add thermal layers or a sleeping bag

Heater blowing cold → gas tank empty / low battery / filter needs reset

Safety Rules (Non-Negotiable)

Never ignore these:

ALWAYS use a carbon monoxide detector
Crack a window when using gas or propane heat
Keep a fire extinguisher inside
Never block heater vents
Don’t run the engine overnight for heat
Check battery levels daily
Avoid sleeping with wet clothes

Your life depends on this section.
