Hi I would like ask maybe I am wrong but . Installers from one company installed for my house hybrid heat pump.They done a lots of mistakes with swapped pipes outside house and inside. It's fixed. But I noticed they put outside washing mashine valve what is necessary but this valve can couse corrosion very fast. For my opinion should be waterproof valve outside what you think?Also they done poor insulation of all pipes outside.
