As the UK prepares for colder months, it's time to think about draining and storing your outdoor water heater to ensure it remains in top condition. Whether you're a passionate camper, caravan owner, or outdoor enthusiast, knowing how to properly winterize your Camplux water heater is key to its longevity and performance.
Camplux has a range of reliable outdoor water heaters, like the Camplux Nano 3Pro, the Camplux BD158, and the Camplux BW422, designed for outdoor, camping, and caravan use. In this guide, we’ll walk you through the essential steps to drain and store these units for the off-season, so you can keep them running smoothly year after year.
Why Draining and Storing Your Camplux Water Heater Is Important
Outdoor water heaters are exposed to a range of weather conditions, and in colder months, the water inside the water heater can freeze, potentially causing damage to the unit. Draining and storing your Camplux water heater properly not only protects it from freezing but also extends its lifespan, ensuring it’s ready for use when the camping season returns.

Step-by-Step Guide to Draining Your Camplux Water Heater
1. Turn Off the Wter Heater and Gas Supply
Before you begin draining your Camplux water heater, make sure the gas supply is turned off and the unit is completely powered down. For safety, disconnect the gas cylinder from the water heater.
2. Open the Water Flow
Ensure that any water pressure in the system is released. Open the faucet or water valve connected to your water heater to allow the water to flow out. This will relieve any remaining pressure inside the unit.
3. Locate the Drain Plug
Most Camplux water heaters, such as the Camplux AY132B and Camplux BW264BC, feature a drainage plug located at the bottom of the unit. This plug needs to be unscrewed to allow the remaining water inside to drain out. Make sure to position the water heater in a way that water can drain freely.
4. Drain the Water Heater Completely
Allow the water to drain from the unit completely. You may need to gently tilt the water heater to ensure all the water has drained from the internal components.
5. Flush the System (Optional)
For additional maintenance, consider flushing the system with clean water before draining it. This can help remove any sediment or debris that may have accumulated inside the water heater, improving its efficiency and lifespan.
6. Dry and Inspect
After draining, dry the exterior and inspect the unit for any visible signs of wear or leaks. Check the connections, valves, and hoses for any issues that may need attention.
How to Store Your Camplux Water Heater for the Off-Season
Once you’ve drained your Camplux water heater, it’s time to store it properly to ensure it stays in good condition during the off-season.
1. Clean and Dry the Water Heater
Before storing the water heater, ensure that it is thoroughly cleaned and completely dry. Any moisture left inside could encourage the growth of mould or rust, which could damage the unit over time.
2. Protect from the Elements
Store your water heater in a cool, dry place, ideally indoors, where it won’t be exposed to extreme temperatures or moisture. If storing it outdoors, consider using a protective cover specifically designed for your Camplux model.
3. Keep the Water Heater Upright
Always store the water heater in an upright position to avoid any internal damage. Ensure that it is stable and won’t be knocked over during the off-season.
4. Check for Damage and Leaks
Before storing, check all components for wear and tear. Look for any signs of leaks or cracks, especially around the water inlet and outlet connections.
