If you install a geo heat pump you need to get the hot water portion when you order it. Waterfurnace does not have a add on. The other thing is when it is finished check to make sure the hot water part it working again it goes back to the installer. I had one that was installed 3 years ago and the dip switch was not set when I went to work on it. The owner went all that time without it working.
Are you sure?
