Can you offer some evidence of this? I don't see how adding a refrigerant to water heat exchanger after the compressor, before the reversing valve, could possibly hurt the longevity of a system.

Thing with mini-splits is you replace the entire unit so it doesn't matter.

The nearly infinite amount of forum posts about heat pumps dying prematurely and costing thousands and thousands to fix. You don't see how adding complexity on top of complexity in a complex system add points of failures ?

I forgot this is an american centric forum and things are just made cheap/disposable because "it's cheaper'
