WINTERIZING A WATER SYSTEM WITH A WATER HEATER & HOW TO PREP FOR PROLONGED STORAGE
Getting your van ready for winter is key for a long and happy van life. This video covers how to best prepare your battery for prolonged storage and how to prepare your water system (if it has water heater) for extreme temperatures. If your van has no water heater, please watch this video.
If you have any questions about the procedures covered in this video, please reach out to our service and warranty department at [email protected].

*Outside Van is not responsible for damage resulting from improper winterization. This serves only as a guide to basic procedures.
When storing your van, use the same precautions as you would in your own home in regard to perishables, ventilation, winterizing, and rain protection. For prolonged storage periods, we recommend flushing out all the drain lines and holding tanks as well as drain the entire water system. Instructions on how to drain your water system will be covered in the “winterization” section of this video.
If your van is going to sit for periods longer than 2 months, we recommend disconnecting the current to all of the chassis’ electric consumers. This can be done using the battery isolator switch, depending of your chassis can be located to the right of the accelerator pedal in the driver’s foot well. Slide the red release down and pull it off the post. The operator’s manual will describe its location, operation, and cautions in detail. This process will save jump starts, battery charge ups, and possible battery damage and replacement in the future.
WEBASTO HEATING UNITS:
Step 1: Drain the Webasto tank, by holding the control knob all the way to the left, a spring loaded position, for 5 seconds or until the green back lighting begins to flash. This will initiate the dump sequence which will last for about 90 minutes.
Step 2: Drain the main water tank.
Step 3: Once both tanks are empty run the pump for about five seconds, then blow the system out. To blow out the system, after the pump has run briefly, open up the sink faucet valve in the warm position, and the rear shower in the warm position and apply air from a compressor to the Schrader valve that is revealed with the water system. Water and air will exit the system through the shower and the sink faucet. Once the water stops spitting out, turn off the shower and sink faucets. Close the drain valve for the fresh water tank and you are done.
ESPAR HEATING UNITS:
If you have an Espar hydronic heating system, the heating loop does not require winterizing. The domestic hot water loop will get winterized with the rest of the interior domestic water loop by either blowing it out with air or adding domestic water antifreeze to the system
