Jim,
Im sorry to hear that. Jehmco is is usually really good to work with... heaters are a tough item as they all are pretty much hit or miss these days but Surprised John wouldnt take them back .
before you pitch them maybe someone can use them for a water storage barrel? Hate to see them go to waste. I have had heaters leds go out and the heater worked fine even after that....I guess it all depends on how its wired.
Bummer on the whole affair though.
Al
