What is a Heat Pump that is Wall Mounted?
Heat pumps are very similar to cooling-only systems, with one exception. A special valve in the refrigeration system allows the refrigeration cycle to be operated in reverse.
A cooling only system cools the indoor air and discharges heat to the outdoors. A heat pump that is wall mounted can also cool the indoor air, but when the valve is reversed, the indoor air is heated.
A supplementary electric heater may also be used to assist the heat pump at lower outdoor temperatures. In colder climates, heat pumps do require a defrost period, during which the electric heater is the primary source of heating the interior of the building.

What is a PTAC / PTHP Heat Pump?
A PTAC ( packaged terminal air conditioner) is a unit that cools and heats. These are heat pumps wall mounted for space saving and convenience.
A PTAC provides warm air using an electric heater (heat strip).
A PTHP ( packaged terminal heat pump) uses its compressor all year round to either heat or cool. In warm weather, they efficiently capture heat from inside the building and pump it outside for cooling. How a Heat Pump Wall Mounted Works
In cool weather, they capture heat from outdoor air and pump it into the building, adding heat from electric heat strips as necessary, in order to efficiently provide heat.
Control Panel
When the external temperature is 38 degrees Fahrenheit or lower, a PTHP unit switches to heat strip operation in order to provide heat. PTHP units are similar to a high quality version of the window-mounted air conditioner with the heat pump accessories added.
Heat pumps wall mounted models are often called "through-the-wall" units since they are usually installed in a sleeve passing through the outdoor building wall. PTHP's are completely self contained, requiring only a permanent electrical connection. They use the outdoor air as the heat source in winter and as a heat sink in summer. They can also provide air assisted ventilation. These heat pumps wall mounted units are typically used in hotel and motel rooms and are also great for offices, sunrooms, room additions, and garages.
Electric Circuit Requirements
The heat pumps wall mounted will require their own dedicated power electric circuit. The size of the electric circuit will depend on the size of the heat pump unit. These heat pumps wall mounted are sized to the space required to be conditioned.

Electrical Project Skill Level:
Intermediate to Advanced - Best performed by a Licensed Electrical Contractor.
Electrical Tools Required:
Basic Electricians Pouch Hand Tools and a Voltage Tester.
Estimated Time:
Depends on personal level experience, ability to work with tools, install electrical circuit wiring, and the available access to the project area. Electrical Safety:
Identify the panel circuits found in the project area, turn them OFF and Tag them with a Note before working with the electrical wiring.
Electrical Wiring Parts and Materials:
Electrical parts and materials for home wiring projects should be approved for the specific project and compliant with local and national electrical codes.
Electrical Codes and Inspections:
Installing additional home electrical wiring should be done according to local and national electrical codes with a permit and be inspected.
This is a testing tool that is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
This is great to troubleshoot a problem with outlet circuit wiring, is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets
Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency
Lights indicate if wiring is correct and indicator light chart is included
Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect, Very handy and easy to use.
A wire stripping tool used to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.
I think your site offers the the clearest and best electrical information for homeowners I have ever seen on the net.You have given me confidence to do my own projects which I never had before. THANK YOU! Paul, from Foxboro, Massachusetts
I wish I found this site earlier, it is by far the best electrical related resource I have found on the web. George, from Scranton, Pennsylvania
I love this site for an office worker that does not know anything about electric wiring. Bill, from New York City, New York
This site is so much better than the 3 books I just bought, I wish I came here first. Collin, from Grand Rapids, Michigan
Thank you for answering my question.
