Well, as somebody predicted, parts are not available for the Ruud UGED series. I hope somebody familier with Ruud can confirm that, but the service provider I have been dealing with for years says that the model is EOL and the burner assembly is not available. Apparently Ruud did have a recall on that unit at one time, but with parts not available, it cannot be fixed. I AM getting a $375 credit towards a new Rheem unit (Ruud and Rheem now being the same company, for those few not aware of that..).
Having called the local distributer and social engineered my way through the system, I got the same story from a different rep. Any confirmation from somebody on the board?
As for the burner assembly, just for grins and giggles I subjected the "slag" deposits to a magnet, and they are ferrous. Where the iron/steel came from is beyond me, as the heat exchanger is in good shape, and the flue is PVC. Additionally, the vent pipes do not have iron ore deposits hanging underneath, so if somebody has a hint as to where the iron deposits came from to contaminate the burner assembly, I would be happy to listen.
So I have my choice between a Rheem RGRJ 100 btu, 92% efficient, 20 year HX/5 year warranty, or a Rheem RGRA with a lifetime HX warranty. Other than the warranty length, I cannot tell the difference between them. Suggestions on a replacement model from Rheem ? Is a dual speed model save energy over a single speed? Other benifits? Guidance please. Also, the total installed price is $1990 for the RGRJ unit, I am getting prices tommorrow for the higher model...this is after the $375 credit. And an Aprilair 400 humidifier is $400 installed, which I thought was high considering I can get it for about $150-$170 I think via a 'net reseller.
Opinions on the pricing are welcome.
I am going to keep the old unit and strip it of parts, to try to recoup $100-200 on the IFC board, blower motors, etc.
