Wood-fired hot tubs take a little more time and patience than their electric cousins before you’re steaming under the stars, but that’s part of the charm. On average, they need 3–4 hours to heat, and knowing the basics makes the process simple.
Master these steps, and on your next glamping holiday with a hot tub, you’ll spend less time stoking logs and more time sinking into the water. Here’s how to get it right. Here are a few tips to get your hot tub technique up to a simmer before you arrive.

It usually takes 3-4 hours to heat the water up to the correct temperature, which is around 38°C.
Keep checking the fire. If you leave it and disappear for a few hours, the fire will die, and you’ll be left staring at a giant water pail.
Keep the lid on the hot tub – you have saucepans at home, right? Same idea.
Stir the water at regular intervals or you’ll get a shock when you step down into the cold depths.
