Excerpt from: = Will Utilities Warm Up to Low-Temperature Heat Pumps? = 2.3.06 Jay Stein, Managing Director, E Source Research, Plattshttp://www.energypulse.net/centers/article/article_print.cfm?a_id=1199 What Is a Low-Temperature Heat Pump? We have defined the low-temperature heat pump (LTHP) as an air-source unit, capable of providing both heating and cooling, that:
A heatpump that only has one stage of heat and one stage of cool.
I just had a 15 SEER Ruud Heat Pump installed. It says, 'Made in Mexico' on back of unit.
Reverses the flow of refrigerant through the system so it absorbs the heat from the outside ambient air and then rejects the heat through the evaporator and into your duct work.
A heat pump is one part, of a two part heating and cooling system and can be used as the primary heating unit in mild winter locations. They can also be used to supplement other heating systems where the temperatures are sub-freezing for longer time periods. Heat pumps also are used in summer for cooling. Basically, the way the system works in cooling mode is the same as most any other AC system. When winter comes it essentially runs the system in reverse to produce heat instead of cooling. The advantage is that it is very cheap to run. The biggest two disadvantages are the compressor has to run during both seasons, causing wear... and ... after you get to about 26 degrees F., the heat pump needs auxiliary heat (gas or electric coil) to warm your house. For most warmer climates they are the best choice. Speak with an HVAC professional to determine your region's best heating option.
For years the name Lennox came up as the most reliable heat pumps and furnaces. The truth nowadays is it is much more important how it is installed and sized than what who makes it. The parts in these heat pumps are very similar- same compressor(most use a Copeland scroll compressor), same gauge copper, similar coils, same brand fan and blowers, etc. The most expensive heat pump will fail soon if not installed properly.
