Maintenance Contract?

[Oggy512]

I just got the offer from Stiebel for a new Maintananceperiod, 580 Euro for a check within 2 years… That‘s pretty expensive, especially since they just check and look and do some filter cleaning, as far as I understood the offer. Those things I can do on my own I guess…

How do you guys handle that? Do you have maintanance contract? And if so, how much is it?

I only let them do the mandatory check to keep the 5 years warranty. Once this period is over I will take care of it by myself. IMO with all the logging and tracing we have, our insight in our own system is far better than the generic knowledge of the Stiebel dudes.

I have never had a contract and have not needed any maintenance or repairs in the seven years since I got the heat pump.
So far, I have done everything myself.

A neighbor, who also has an 8-year-old Tecalor heat pump, called customer service last year for maintenance.
It cost a lot of money, they checked everything but didn't have to do anything major.

He should start using this project 😋

I offered to help him with the maintenance because he's all thumbs. But he didn't accept my offer and called customer service anyway.

That does not look like it is worth 580€ :D

[kr0ner]

we could automate half of it

[Oggy512]

Should I Open an issue/feature request for implementing Parts of the maintaenance Tanks as automation?

but yes, I definetly wont close that contract… 580 is way too much.
I‘ll do the steps on my own, based on the Word doc from the other thread.

(When we Build the House, we had a 4 years contract with 2 inspections included. That now oder and we‘re in the fifth year)

yes please

I had the maintenance done once, and it was outrageous for the price he wanted. I never mentioned it to my installer because I never received a bill.

Now I do the maintenance myself. Even without this project, I've completely configured the system myself.
I buy the filters from sparhai24, my installer buys them there too :)

My neighbors have identical settings, and I use a third less electricity and it's warmer! They have their maintenance done regularly, but their electricity consumption hasn't improved at all.

I can only confirm that.

Because they (Stiebel technicians and your neighbors) don't even have the data to tune it properly ... they look at the values for 5 minutes and that's it. Without continuous tracking and adjustments you cannot solve this. But this is the "Energiewende" 😢

The owner of the maintenance company used to be a Stiebel engineer, so overall he's great.

he believes you can always adjust a system, which isn't true. The colder it is, the better you can adjust it.
this naturally saves him time and money, as he can make adjustments at any time, and not just when the system needs to be efficient.
