Do I need to change the oil?

Updated over a month ago

All oil-filled heaters from Mill are maintenance-free and come pre-filled with the correct oil from the factory.

This oil does not need to be replaced or refilled.

If your oil heater develops a leak, we ask that you bring the heater along with your receipt to your retailer. They will assist you further with your case. Alternatively, you can contact Mill support.
