A heat pump is a machine or device that moves heat from one location (the 'source') at a lower temperature to another location (the 'sink' or 'heat sink') at a higher temperature using mechanical work or a high-temperature heat source. The difference between a heat pump and a normal air conditioner is that a heat pump can be used to heat a home as well as cool it. Even though the heat pump can heat, it still uses the same basic refrigeration cycle to do this. In other words a heat pump can change which coil is the condenser and which the evaporator. In cooler climates it is common to have heat pumps that are able only to heat the house. Common examples are food refrigerators and freezers, air conditioners, and reversible-cycle heat pumps for providing space heat. In heating, ventilation, and air conditioning (HVAC) applications, a heat pump normally refers to a vapor-compression refrigeration device that includes a reversing valve and optimized heat exchangers so that the direction of heat flow may be reversed. Most commonly, heat pumps draw heat from the air or from the ground. From Wikipedia under the

I am looking for a rating or maintenance history for the various manufacturers of heat pumps (not geothermal). I've checked Consumer Reports and didn't have any luck. Doing some research online I got conflicting info (one person raves about brand X followed by some saying never buy brand X). Any info in appreciated. Asked by Genghis334 - Sat Aug 5 23:40:44 2006 - - 2 Answers - 0 Comments A. I will give you what I got. I do not have ratings or maintenance history, but I am a heating/cooling technician. I work for a company called Carrier. You may have heard of us. We own a ton of stuff Bryant/Payne just to name a couple. I say the best unit for your money is a brand called Tempstar. It is actually a very good unit. They have a website you can check them out. Answered by Scott M - Sun Aug 6 08:19:13 2006 Are heat pumps as good as solar water heaters? Q. I live on the NSW south coast and am considering installing a solar hot water system. I have recently been reading about heat pumps but cannot find any comparisons between the systems. Can anyone advise me? Asked by Cecil - Sat Nov 8 22:11:01 2008 - - 1 Answers - 0 Comments A. They are different. If you are willing to risk not having hot water once in a while but get your hot water for free after the cost of installing the system or just to have an electric or gas backup. The heat pump is going to work any time you have power which is probably pretty much always but it costs money to run it after you have paid to install it. I have a geothermal heat pump to heat and cool my home in Wisconsin. In summer it does heat most of my water by cooling the house but it still does not run for free. In my opinion if your just thinking about the hot water go solar because once it is in it pretty much is running for free and I like free.

Q. We had our gas heat replaced with a heat pump. The electric company said we would get a credit for making our home more energy efficent but the tax accountant said there is no tax credit for the heat pump. Is this true? Asked by April - Tue Jan 12 10:15:36 2010 - - 3 Answers - 0 Comments A. Certain items qualify for the tax credit. Go to the IRS web site and do a search for energy tax credit. Heat pumps offer an energy-efficient alternative to furnaces and air conditioners in moderate climates. Like your refrigerator, heat pumps use electricity to move heat from a cool space into a warm, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house; during the cooling season, heat pumps move heat from your cool house into the warm outdoors. Because they move heat rather than generate heat, heat pumps can provide up to 4 times the amount of energy they consume.
