The Split-System heat pump supplies efficient heating and cooling for your home. This is achievable because a heat pump moves free solar heat as opposed to producing it from some type of energy resource. The hot air that is exhausted from the rear of your refrigerator is not heat produced, but heat being transferred from inside to the outside. The process with a heat pump is the same and it is reversed depending of the season.
The triple-function heat pump not only warms and cools your home, it also heats water by means of the use of a "desuperheater" by extracting heat from the systems refrigerant and using it to heat water. This feature can provide essentially free water heating during the summer and a much more efficient use of energy for heating water in the winter.
Split-systems are much better since the interior unit is smaller and the majority of the noise is on the exterior. Also you don't have to drain water from the inside component due to the evaporator is on the exterior unit.
A drawback of this system compared with a package unit is a space is needed for the exterior unit. This may be difficult on multi-level dwellings, townhouse, zero lot line patio homes, etc. In contrast to window Air conditioning unit, the split system does not have an option of exchange of indoor and outdoor air. A benefit is there is only a small hole for the coolant conduit to pass between the exterior and interior units. A window air conditioning unit can be easily removed by an intruder allowing a passage into your house.
You can calculate the energy cost of the split-system heat pump by checking out the efficiency rating of a particular model and plugging the rate your energy provider is charging you. Also since these heat pumps are high efficiency, the IRS will allow you a nice tax credit.
