Havasu got a 22% electric rate increase this year and because the summer A/C season is coming up, I've got some questions about availability of devices that I believe would boost efficiency of my home a/c unit and cut electricity usage.
I'm wondering if liquid-to-liquid heat exchangers exist for a/c retrofit that either replace the a/c's condenser and fan or work in tandem with it. I think I could run a loop with 2 of these. The first unit would pre-heat the cold water going to my water heater. The second would have my pool water circulated thru it. If anyone knows availability and cost on such a system, I'm interested!
