Right now the math suggests I'll save about $1050 over 5 years and $11,050 over 25 if the current rate of inflation on my electric bills keep happening. Even if I have to buy a commercial heat exchanger and add 2 more pumps I will be doing this. If I can get away with the single wall exchanger then my system should cost me about $1200 with half of it already purchased. if I need to go double wall flat plate add at least $1000 if I build my own double wall with air gap think coils wrapped around a central tube I think I can do it for only $500ish.
If I need to I'll say **** the permit.
So yeah I will be doing this period.
