Default Wow!

Congratulations & Great work!
If you know the water pump flow rate you can figure the efficiency coefficient from the temp rise vs watts. If not you can see how long it takes to come from whatever your start cold tank temp is to your cutoff tank temp, then figure that against amps x voltage over the time it took.
Be sure to get some temp and pressure cutouts (off some of those heat pumps you junk!)and put then on that puppy before you leave it alone!
Are you using the stock cap tube? And what temp is your basement air going in?
This will get me to work finishing mine!
