Im Replacing a 300E today under warranty as the compressor has failed.

What is the age of the unit ?

I view HPWH like window or through the wall AC units.
If out of warranty they are a throw away as they will cost more to fix than they are worth. If you luck out and get a good one it may run a long time. No one is going to bother fixing one if it is a refrigeration problem
Will the fuel savings the eventual cost of ownership. Doubtful
Are you "going green" using a HPWH that ends up in the dump and will there average lif outlast a tank type water heater?

I just want to have tank water heater again and not burn fuel oil in the summertime. With the 10-year warranty if I do have a failure I'm good for quite a while. I'll have to register the unit once I get it installed and Thursday after work, my utility is holding a workshop on their efficiency programs so I'll have to bring all of my pertinent info to do the rebate for the unit.

my friend assured me this was the case and then said look it up when i asked for evidence when we were talking about mini splits. if we required them to be well designed and reliable i'd be all for mini splits but price seems to be the only design criteria.

I am not against them. I just don't envision them being repairable in this day and age. Unfortunately, we have become a throw away society. I don't mind paying big $$$ for something that will last.

@EBEBRATT-Ed unfortunately that is the truth about us becoming a throw away society. I'm all for repairing things and making things last as long as possible. I also try to buy the very best I can when making a major purchase like this or for example my zero turn mower and that way I'm a little more sure that it'll last as long as possible with as minimal problems as possible.

@EBEBRATT-Ed A HPWH with a failed compressor is still a resistance tank, it will work just as well as one. Around me that is still cheaper to run than an oil boiler to heat DHW in the summer.
Some of the smaller failed compressors I have dealt with usually had failed fans or clogged coils. I'm wondering how many of the issues are due to neglect or install in too small of a space.

are the compressors actually failing or is the refrigerant escaping and then maybe after running without refrigerant for a few months the compressor eats itself?

IMHO most refrigeration failures are due to neglect in maintenance. Keep the heat transfer coils clean.
In the old days they talked a lot about compressor failures. Compressors don't fail very often if at all due to a "bad compressor".
Most of the time they fail due to loss of refrigerant due to leaks or dirty/clogged heat transfer which forces the compressor to run outside its design envelope.
A lot of units could be saved if the MFGs were not so cheap and installed HP & LP switches which would PU the loss of charge. With the controls they have now they cold lock the compressor of if the HP or LP trips 10 times in a given time frame.
This would prevent nuisance service calls but provide better protection

If the end users didn't want cheap, cheaper, cheapest the manufactures would install those safetys.

it isn't quite so much what the end user wants but what the bank building a development and selling it to the end user wants. I think far more stuff is sold for cookie cutter new construction than to the homeowner or custom new construction.

The failures I am aware of in my market are due to a specific error code that is just a broad "compressor not working" error. the particular manufacturer just refuses to troubleshoot the issue as they assume anyone installing these is a plumber and not licensed to handle refrigerants…… I have had more than one replaced under warranty that turned out to be nothing more than a failed capacitor.

And where does the old HPWH go when it dies? You can't just scrap it. the refrigerant charge needs to be recovered and disposed of properly. Our local Johnston Supply charges $75 to take the recovered tank. And then there is the labor associated with it. There is a lot more involved with a HPWH than just a swap

i'm guessing the charge having escaped will be the reason it dies. or it will stop being a heat pump and run on resistance until it leaks.

I don't have any dog in the fight but, did read thru the warranty. It seemed to be the typical write up.
However, "warranty void if tank not drained if there is a +2 day power failure".
Can anyone explain that??

powered anode

Could anyone expound on this reasoning with the powered anode?
0 -
if there is no power then there is no current to make the powered anode protect the tank from corrosion.
1 -
Hi, Rust isn't going to make much progress in two days. I've seen lots of tanks that clearly had no anode for years, but kept going. So, the two day thing sounds overly conservative to me.
Yours, Larry

The damage is cumulative too so if it was full of water and not powered for a total of a month or 2 during its life because of several several day long power outages that probably wouldn't be a big deal but on the other hand if you said the limit was 2 weeks and you went away for 2 weeks 3 times a year and left it unpowered for and full of water for each of those trips you might have a problem.
They need to make a complex problem simple enough to be enforceable in a warranty.
