Is an air conditioner with a heat pump function worth it?

Hello,

it's been quite warm lately, so our house is heating up quite a bit. My spontaneous idea was to get a split air conditioning unit and I wanted to find out how much these things cost.

In the process, I came across inverter air conditioners that can also heat and are supposed to save energy costs compared to oil heating.

Does anyone know about this? Does heating really save energy? Is there perhaps even the possibility of getting a [KfW funding]?

Thank you all!

It's a classic air-to-air heat pump - nowadays all split-system air conditioners (inverter) can do that.

The COP values aren't that bad, it can be used well as additional heating (we had it in our rental place) because it feels like it quickly provides cozy warmth (but it also disappears quickly again since air is a poor heat carrier).

It's always funny how the warm days cause the short climate boom every year - how many people then reconsider it.

Inverter or not inverter, what’s inside is classic technology decades old, everything tested and functional.

Just buy a system you like and have it installed.

Thanks in advance!

Sure, you tend to focus more quickly on things that bother you.

The problem is rather, what do I like, how do I recognize if it is good, and mainly, is the heating function worthwhile/profitable?

It probably won’t be profitable - or how do you want to calculate that? Do you have an oil burner at home? Milling is another matter - the function is usually always included. So...

Yes, I have a low-temperature oil heating system. Replacing it simply does not make sense yet.

I am just ignorant in the field of air conditioning, maybe my question was unfounded?
I thought there are air conditioners and invert air conditioners, meaning additionally with a heating function. That's how I understood it.
I read that invert air conditioners produce heat more cheaply than oil burners. I assumed that invert air conditioners are more expensive than regular air conditioners and therefore wanted to know if the extra effort is worth it, or if it is better to just install a regular air conditioner?
