Warranty extension for heat pump from alpha innotec - is it worth it?

In May, a heat pump from alpha innotec for hot water and heating was installed in our single-family house. We have a 5-year warranty on it. Now we have received an offer to extend the warranty to 10 years. The total cost for the warranty extension is about Euro 1500.- An additional condition is an annual maintenance currently costing Euro 407.- per year. What do you think about this? Is it worth it?

Did you have them commissioned by the factory service? We were told that you only get the 5-year warranty then (this was subject to an extra charge - €500 - commissioning by AI itself).

We should also conclude a maintenance contract, costs were not mentioned. Our AI brine-water heat pump has been running trouble-free for 2 years now ;-) and I don’t expect anything in the next 8 years either (of course, I can’t bet on that). But the approximately 3.5K for 5 years of maintenance and extended warranty is a bet that AI is sure to win, at least statistically. Otherwise, they wouldn’t offer it ;-)

Hard to estimate, we had been offered something similar that only required maintenance (ändere Hersteller). We were also planning to go for it. You can also think of it as a kind of insurance that costs about €50/month for the next 10 years.

Have you had them commissioned by the factory service?

We had them commissioned by the factory service and paid the additional charge.

If the heat pump breaks down after 10 years and one day, it is not worth it. If it breaks down after 5 years and one day, it is worth it. That's how it is with all insurances. You take them out and hope you never need them.
