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. > ... mini heat pumps won't last 10 years, and by the time it dies you won't be able to find a replacement for your specific model Thing with mini-splits is you replace the entire unit so it doesn't matter.

> 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. 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 ? > Thing with mini-splits is you replace the entire unit so it doesn't matter. I forgot this is an american centric forum and things are just made cheap/disposable because "it's cheaper'

  > You don't see how adding complexity on top of complexity in a complex system add points of failures ? I don't see see a heat pump as complex. It's a compressor, valves and coils. The complexity are the stupid computers foisted onto us. > I forgot this is an american centric forum and things are just made cheap/disposable because "it's cheaper' We don't have a choice. Do you? We're all at the mercy of the manufactures.
