Thanks in advance for any advice you may give.
I live in northeast Georgia, near Athens. Hot summers (90-100 late
June through August, mild winters - coldest was 6 below, but usually
teens to 30s from late November through mid-March).
I have two 15 year old 1.5 ton Florida Heat Pump water source heat
pump systems on a closed horizontal loop. One is a split system, the
other is not. One has failed completely, and the other has had lots of
repairs and is again in need of a cash infusion. The entire system was
installed by certified
professionals with plenty of experience with water sourced systems.
I'm ready to replace one, maybe both. We don't plan on
Has this technology become more reilable (duh, I know this is a dumb
question, but I don't want to purchase the same problems and suffer
another 15 years of repairs, and heating/cooling bills that were/will
be higher than expected)?
Does the loop material wear out or degrade (thick walled black plastic
pipe 4-6 feet underground)?
Should I consider air sourced heat pumps, or replace with another
I've been told to not purchase the highest efficiency systems as they
are more prone to need repairs (don't get the lowest cost "contractor
Also I've been told to keep it simple (no zoned system with dampers,
etc. as these too tend to need more frequent repairs).
Any suggestions on whether to add a "hot water recovery" system for
heating household water in the warmer months?
Any comments or suggestions on air to air versus ground loop and brand
reliability (i.e., Trane, WaterFurnace, FHP, Climate Master, etc.)
would be appreciated.
