I'm on my 2nd heater base and about to go buy a third in 3 years. They work great for the first year out the box, it is maybe plugged in for 3 months. When I plug it in the next year it just doen't work very well. The water was froozen soild this morning! Any one have any expierence or advice with this type of water heater? https://www.familyfarmandhome.com/inet/storefront/store.php?mode=showproductdetail&product=1393 I have a 5 gallon metal water can on top of it.
