As I posted <Link> a couple days back that my heater is broke. On opening the unit up, the heat-exchanger is gone. Based on do-not-repair suggestions, I am ordering a new heater and will be doing the install over the next couple weeks including electrical upgrade and pouring concrete pad.
The old heater parts are up for grabs - if I can pull it and pack it, I will send it to you for the actual cost of shipping USPS. Of course you will not want the heat-exchanger and I cannot guarantee anything else. But any switches or controllers etc. might be useful to someone. The build is from Dec'05.
Send me an IM if you have use for something. If nothing it will go to recycle at the end of the month.
