    Florida Heat pump

    So I am buying a house, and I know a little about bosch geothermal heat pumps. So here goes my silly question. There is a heat pump on the third floor of this house, but its a water to water source. Here is the part im not really understanding, why in the world is the water in connected to the hot water house supply. I always thought that most house heat pumps use refrigerant. and water to water was mainly for pump and dump and closed loop geo thermal systems. Sorry this is not my field, I am a PV installer and can help with electrical problems mostly, which this isnt lol.

    Most likely it uses the compressor heat to HEAT the domestic hot water.

    I agree. This is a way to help your water heater heat the water in your home. Often times it hooked up as a hot water recover system that allows the compressor heat to be used to help heat the water.

    Not a bad idea at all. Getting everything possiable from the system including helping the water heater to heat the water besides heating elements. Often when I see this setup they were used in the 90's as a add on to sale a system.

    As long as system is sized proper and designed to work with water heater it's not a problem. I would ask who is servicing your equipment to review the setup.

    Nice post and links. While its been quiet a few years since I have worked on one myself. I do get calls from the plumbing side of my company asking me what they are looking at. Often times it just that a hot water recover system.

    From what I have seen either they work right or don't. If installed and serviced with the equipment can be a good thing but on the other hand to many were not installed properly and lead to problems in my area. I have disconnected more then I connected.

    What you might want to do is have out your hvac service provider or plumber to review over and see how all is working and if is worth the headache. My grandfather in law has one on his 1994 Trane XL1200 heat pump that has worked great for many years but the time is getting near where we will need to be changed the unit so I will also have to review and see if worth keeping in his home.

    While some of the ways this systems are hooked up to older equipment is not excepted by any manfactor without voilding the warranty. Keep us posted on the outcome.

    _ Payback _ is probably in the 25+ year range.

    I wonder who wishes a cheap PITA to try to save ~ $6 / year.

    Thanks for the info and links. I have taken the Bosch geothermal class called bits and pieces. I assumed that all heat pumps need a compressor somewhere. The problem with this is that there is no compressor line set or compressor outside of the building. I cannot enter the house until I close but for now in left pondering exactly what I have to work with. This unit sits between to cathedral ceiling rooms and blows in and returns on the wall of each side of the room. Probably not very efficient but the house was built 1875 and isn't a easy rip the floor up and run ducts kinda deal. Will probably end up replacing unit with a new york furnace but my next question is what is the code on mounting condensers on a roof that has a small pitch, and if the roof is over a bedroom would it make for a lot of noise in the summer time? Thanks for the help everyone. I really appreciate it.

    THE CODE ( reading between the lines ...)
    AS i SEE IT IN THIS APPLICATION ...
    I presume you have a Huge Life Insurance policy on your wife
    _ _ and you're planning on using a different bedroom.

    and THEN I AM gonna strap that condensing unit on my back and
    Flap my wings to get that unit on the roof.

    I was thinking of asking one of my Flighty Friends
    if they could do some load sharing.

    How many times must one fix something before it is fixed?

    No condenser? Sounds like you may have a package geo unit. Post pics so we can help further.
