**TWO QUID TO TURN VANILLA INTO A TINY HOTEL 🔥🚐**

Wednesday night gave me one of those wonderfully simple campervan discoveries: staying properly warm off-grid really doesn't cost very much.

Outside, the September night gradually cooled towards about 15°C. Inside Vanilla, the Webasto quietly kept the living space hovering around a wonderfully comfortable 23°C. Not for half an hour while I made a brew, but right through the night.

And then I wondered the obvious question:

What did all that warmth actually cost?

The answer is surprisingly pleasing.

Vanilla's Webasto Air Top 2000 STC doesn't heat the van by hammering the leisure battery. The battery mainly runs the electronics, fan and fuel system. The actual heat comes from burning a very small quantity of diesel.

Webasto quotes diesel consumption of roughly 0.12 to 0.24 litres per hour while the burner is operating, depending on how much heat it's producing.

My temperature data showed that the heater wasn't simply charging along at maximum output all night. Vanilla warmed up, coasted, cooled slightly and then warmed again, repeatedly holding the interior in roughly the same comfortable band.

So although I can't measure the exact amount of diesel used without physically measuring the fuel, a sensible real-world estimate for this mild autumn night is somewhere around £2 to £3 with diesel approaching £2 a litre.

Call it roughly the price of a coffee.

For nearly twelve hours of warmth.

That's rather brilliant.

Earlier that day, Vanilla's 200 W solar panel had harvested 390 Wh of energy. SolarHistory(20261001-061433)

That energy went into the leisure electrical system before darkness arrived.

So while there is obviously a cost involved in owning the solar equipment and battery, the electricity generated that Wednesday had no meter ticking away and no campsite hookup bill attached.

Sunlight arrived.

The panel caught it.

The battery stored it.

And after sunset some of that energy helped run the heater, fridge and everything else keeping Vanilla comfortable.

There is something deeply satisfying about that.

Imagine telling somebody years ago that you could park a campervan away from mains electricity, leave a diesel heater automatically controlling the temperature all night, keep the fridge running, monitor the entire thing from your phone and wake up with the van still beautifully warm.

They'd probably assume it involved a generator chuntering away outside.

Instead:

☀️ Sunlight supplied the electricity. ⛽ A small amount of diesel supplied the heat. 🌡️ The Webasto controlled the temperature. 🔥 Vanilla stayed around 23°C. 💷 Estimated heating cost: roughly £2–£3.

That's probably only around 20 pence an hour for a warm campervan on an autumn night.

And for me, that's the magic of the system.

It's not about sitting inside wrapped in three sleeping bags congratulating yourself on being "off-grid".

It's about being off-grid without feeling off-grid.

Warm bed. Cold beer. Fridge humming away. No hookup cable disappearing across the grass.

Outside can do what it likes.

Inside Vanilla?

Webasto weather. 🔥🚐
