Hmmmm. Sounds interesting. How much water, at what incoming temperature, is required to feed your water-to-water heat pump? Where do you dump the "used" water? What manufacturer made the heat pump? How expensive was it to buy and maintain?
Around 5gpm more or less, my ground water here is 54*. BTW...The temps of the water source are not that important...you make up for lower temps by increasing the flow rate. There are a lot of btu's available in a stream of many gallons of water. My discharge temps are 39*. And I raise the DHW by 5* each pass through w/ a 1" circulating pump to storage tank.
My discharge water goes to a drain field I created specifically for it. It would be mind boggling as to how much water I have discharged in 15 years for htg./ cooling/ and water heating.
I have had a Ground Source Heat Pump which besides "water to air" has "water to water" heat exchangers.
That gives me all three...Htg./Cooling/Hot Water.
But, after a search online, I didn't see much to compete w/ the new arrival of the Air to Water units being offered now.
