Air heat pump or use gas and solar?

I find that unprofessional and therefore I reject such a product.

This is the maintenance contract. You have to do it if you want to keep the warranty, which does make sense for a new device.

Does the maintenance contract for an air-to-water heat pump from Waterkotte cost exactly the same, then?

How good that the responsible citizen doesn’t have to sign anything.

You are not allowed to post links here, but if you visit the Waterkotte website, you will find what you are looking for very quickly. Everything probably costs the same, which is not surprising, since an air-water heat pump, I think, contains even more technology and wear parts. A brine heat pump is still quite simply constructed.

Of course, you can do without it. But if something goes wrong with the system, these costs give you a foretaste of what a normal craftsman's service costs. That's what I always say. With such products, you pay yourself silly and stupid with maintenance and repairs. My landlord can tell you a story about that.

Of course, it can also go differently with luck, but there are enough cases where it goes exactly like that.
