ᐅ Is a multi-split air conditioning system suitable for heating?

Does anyone here use a multi-split system for heating, for example as an alternative in older buildings when insulation or renovation is no longer worthwhile?
I’m not familiar with the various split systems, but I’ve come across them often as an alternative to conventional heating when insulation and renovation hardly make sense anymore for the current residents.
I would have concerns about noise, drafts, and the resulting dust circulation since it is an air-to-air heat pump after all.
A photovoltaic system would at least be available for the transitional period from spring to autumn.

Very good air conditioning units are available for €500-700 (approximately $540-$760), and decent ones starting from around €300 (about $320). You can install them yourself or know someone who knows someone.....They still need to be developed at that price point. €300 (about $320) 😀Deliverer schrieb:
I know someone who orders cheaply from Italy and doesn’t get prices like these. Doing it yourself is prohibited in Germany and not exactly easy. If you hire someone, you pay €1000 per kW. Currently probably even more.Just roughly calculated, so 5 kW = €5000 including or excluding subsidies?
Let’s say the subsidy is included, so €5000 total – no heating installer would install a 5 kW bivalent air-to-water heat pump into an existing heating system for me. And the hydraulics would probably be messier than before.
And even if they did, that capacity would barely be enough without adjusting or adding to the heating surfaces to reach lower flow temperatures. The option to cool in summer would probably not be available either.

One more thing about prices. I had three cheap air conditioners costing $300–400 (Praktiker -25%, even cheaper on eBay), the first of which broke down after 15 years. I have now replaced it with a inverter unit for $700. The oldest of the cheap ones is now 19 years old. I do the installation myself; commissioning costs me a case of beer.

You still end up paying more compared to a good split system. The operating costs, especially now at over 45 cents per kWh, should not be underestimated if you want to keep your house comfortably cool.

You still lose money compared to a good split system.I believe @Grundaus has also installed split air conditioning systems, just cheaper ones. And in terms of efficiency, they are not that far behind the expensive brands. The extra cost for a Mitsubishi is not recovered.
And electricity only costs around 45 cents for a few cases. The average is 36 cents. With photovoltaic, it’s then 10.
