How to Properly Maintain the Expansion Tank for a Geothermal Heat Pump Water Heater

Maintaining the expansion tank of a geothermal heat pump water heater is a simple yet important task that should be done regularly to ensure your water heater runs smoothly and efficiently. Expansion tanks are designed to absorb any excess pressure in the system which can cause damage to the components if not managed correctly.

To properly maintain your expansion tank, here are a few tips you can follow:

1. Check it regularly: It’s important to check your expansion tank every month or so for any signs of wear or damage. Look for signs of corrosion, rust, or sediment build up as these can cause problems with the expansion tank itself and the water heater in general. If you notice any of these signs, it’s best to replace the tank right away.

2. Clean it properly: Your expansion tank should be cleaned at least twice a year using an appropriate cleaner. Make sure you follow all instructions on the cleaner’s label and wear protective gloves when handling it. Once the tank has been cleaned, flush out the system by running cold water through it while pressing down on the pressure release valve until all the sediment is removed from inside.

3. Refill if necessary: If you’re ever in doubt or notice that your expansion tank isn’t functioning properly, it may be necessary to refill it with air or water depending on its design. You may need to consult a professional for advice on how to do this safely as overfilling can cause damage to other parts of your geothermal heat pump system.

By following these simple tips, you’ll be able to ensure that your geothermal heat pump water heater operates efficiently and effectively for years to come!
