Heat Pumps

A heat pump is an electric cooling and heating system used to compress and decompress gas to heat or cool a house. This mechanical device pumps heat from a cooler to a warmer location and can extract heat from air, water or the earth. Heat pumps functions like an air conditioner in the summer and an electric furnace in the winter, thus encompassing both a heating and cooling unit in one device. The COP, or coefficient of performance, which calculates the ratio of heat output to electric power consumption, measures the performance of a heat pump.

Heat pumps are the most resourceful form of electric heating in moderate climates, and cool a house by collecting the heat inside the house and effectively pumping it outside. There are three types of heat pumps that one can install: air-to-air, water source and ground source. Heat pumps can collect heat from air, water or ground and can utilize the same to heat or cool your home. When installing a heat pump at home, one should consider using an energy-efficient heat pump system, keeping in mind the climate of the region.

For instance, air source heat pumps are a good option for mild and moderate climate regions, and ground source or geothermal heat pumps are efficient in climates with similar heating and cooling loads. The most common types of heat pumps are the air-source and ground-source heat pumps. Although ground source heat pumps are more expensive to install, they are more efficient and less noisy.

However, to make heat pumps work efficiently, they should be installed properly, and one should choose the right sized pump that can fulfill the heating and cooling demands of the house. While selecting a heat pump one should buy a device with a higher Heating Seasonal Performance Factor, or HSPF. The heat pumps should also be fitted with demand-defrost control, which minimizes the defrost cycles and reduces supplementary and heat pump energy use.

Heat pumps are much more cost-effective then other conventional heating devices, and are also becoming more commonly used to heat swimming pools, and hot water for household use.

I would just like to tell everyone geothermal Trane heat pumps suck, we spent thousands of dollars to install 3,000 feet of pipe 7 feet underground and a 5 ton unit in 2003, this week 2010 the thing blew the heat exchanger and put the R-22 out into the underground piping and water into the R-22 system, ruined the compressor and God only knows what else.
Trane only wants another $9500.00 plus dollars to repair it and the Junk is only 7 years old. no wonder Trane closed its Tyler Texas Plant. anyone who makes Junk like that and charges an arm and a leg for it should close down.

I think that harnessing natural energy produced by our planet is the way forward. Geothermal heat pumps are a step in the right direction. I mean can you image when the day comes when all house builders start to install this type of heating system EVERY time a house is built? What a difference it would make to our environment. As long as the technology keeps improving and the prices are sensible, then this would be such an important step forward for us all.

Just my humble opinion.
