Hi Everyone,
i finally have my project near completion and currently running in my shed for testing, bring on the winter!
I have a small stream that is 60 metres from my house and i use this as my heat source. My stream heat exchanger is stainless steel tube formed into a helix to improve internal turbulence and heat transfer.
Evaporator and condenser are coil in shell , titanuim and pvc . All heat exchangers are supplied by vaportec , a company in NZ.

It is a water to water heatpump that will be heating infloor radiant slab .
I will attach some photos of unit and stream exchanger in a few posts.

Cheers Andy
