I'm with you on spending too much money on pump and dump or geo's for that matter.
Look at the total expence, look at the life expectancy, then calculate how much it's going to save you. The bottom line: Is it really worth it?
Some say windmills have a life expectancy of 20 years and it takes 50 years to pay them off.
If it weren't for tax and electric breaks, is it really worth it? Not to mention, there is always something that is going to need repaired.
I'm not so sure when you factor in the cost of the well, how much it cost to pump water, is it really worth it? Would like to see real data, not just use what the guy selling you the unit says it will save.
How many people have a geo heat pump that lasted 20 years and didn't have a service call? How much did it cost and how much did it save?
