Who uses heat exchangers on their tanks?

  • We are currently upgrading MFK. thanks! -neo
What kind of dollar savings are you realizing from installing this?
 
Costs about $5/month to keep 800 gallons to 84F. It has been summer time and warm here though, I should see substantial savings during the winter months over electric heaters.
 
I have installed that type of heat exchanger for pools, for my larger tanks that are in my basement I have the area blocked off and bring the temp up with a constant run dehumidifier. What you have done I've seen on here before minus the heat exchanger, they are expensive. A couple of guys have used pex coiled in their sumps.
What model circulator is that?
