Since we are in the land of make-believe,
I get about 5-10 calls a year on tankless heaters that are in FAIL mode, meaning not working and the wife is considering divorce sooner than later. That's right you married men; odds are at 75% you're not ending your life with your mate, buy a tankless to shorten that time span. A true "leurve-tester" of sorts. LMFAO!!!
It's always the same, and they mentioned they've called every plumber in the book and they are more than frustrated at this point because the initial installer says, "We install them, we don't service them" and away he goes not answering the phone, ever again because he made his dime, why should he sit there for HOURS looking up PDF files and troubleshooting regs and error codes KNOWING the customer is going to expect this time for free, given the fact the consumer now thinks you built this device in your basement with a ball peen hammer and some wires, some copper tubing and a couple screws.
It's worth the loss of a customer at this point because they are now in the "I regret this buying decision" mode because not everyone can afford top of the line tankless heaters, and not everyone can install them themselves.
So, the person on the other end is heated, upset that he's been without hot water for days, not hours and the parts that were sent to him, weren't the right ones, or they didn't fix the problem.
Is this my fault? Are you going to hustle me down because you didn't check out what swayed you to begin with? Anytime I hear "bosch" and "tankless" in the same sentence, I start busting out laughing knowing you got stupid stamped on yo fo-head.
Ain't nuttin' I'm going to deal with, phone call is ending in 3, 2, 1.....click!
Has anyone with a brain figured out WHY the supply houses don't carry repair parts? You think they are going to let you pull parts off the display model? Oh wait, there's a G instead of a P in the serial number...won't work.
"Did you call the friendly tech support M-F 9-6 and WHAT!?!?!?! No weekends?!!?!?! Call back monday?!?!?!
Better call a plumber, maybe he knows someone who "has one of these laying around I can get a part off of."
Fat chance slim shady; you got a better chance rolling doobies for charity than thinking the world is going to stop for one second and fix your box of wonders hanging on the wall.
Like I said, it's make-believe...
