Efficiency of heat pump
Heat pumps are potentially the most efficient type of electric heat. When heat pumps properly installed, heat pumps can deliver 1 1/2 to 3 times more heat energy to a home than the electric energy they consume. Unfortunately, the energy savings produced by the heat pump’s design are often lost to poor installation and neglected maintenance.
All heat pumps include two different heating systems: compressor heating and auxiliary heating. During moderately cool weather, your heat pump engages it’s first stage to heat your home. In this most-efficient mode, it works like an air conditioner in reverse, using a compressor to circulate refrigerant through the outdoor coil and gathering heat from the outdoor air. The refrigerant then carries heat to the indoor coil and releases it into the home. This first stage works well down to about 35 degrees. Below this temperature, heat pumps don’t work as effectively, and the second stage of heat is activated. This less-effective stage utilizes electric resistance coils to produce heat, but it is the only option during severe weather. Heat pump thermostats usually have a light that alerts you when resistance heat is on. The more your system depends on the resistance coils for heating, the higher your energy bill. Efficiency improvements can reduce your reliance on this second-stage electric resistance heat.
Duct leakage is the most serious and common cause of high heat pump energy bills. Duct leaks allow your expensive conditioned air to leak to the outdoors. The most important duct air leaks are those nearest the heat pump’s indoor cabinet because the air pressure is greatest there and the temperature of the air is the highest. Sealing these duct leaks can save you a lot of energy and money.
Incorrect refrigerant charge is another common performance problem. An incorrectly-charged system must work overtime to deliver heat to the home. A qualified technician can check this charge and add or remove refrigerant as needed. Inadequate airflow also lowers the performance of heat pumps, and under-sized ducts are the most common cause. Proper duct sizing solves this problem.
Though many heating and air conditioning companies don’t include testing and adjustment of refrigerant and airflow during their service calls, you should ask to have these important procedures included. Your technician should test and seal duct leaks, check and adjust refrigerant charge, and test and improve airflow. All are worth the expense to be sure that your heat pump is operating at maximum efficiency.humor among police dark humor among us names 21st century humor among us sense of humor among nurses polvo do humor among us nomi black humor among us humor around the world humor around meaning ethnic humor around the world sense of humor around the world best humor in the world different types of humor around the world humor as a rhetorical device humor as a trauma response humor as a core value humor as a value humor as medicine humor as a verb humor at work humor at the expense of others is called humor at work ted talk humor at someone else's expense humor at a funeral humor at work quotes humor at workplace humor at the expense of others quotes humor behind collegehumor behind the scenes vitreous humor behind retina vitreous humor behind the eye psychology behind humor science behind humor hiding behind humor hiding behind humor meaning humor between generations humor differences between cultures correlation between humor and intelligence difference between humor and sarcasm difference between humor and satire difference between humor and wit difference between humor and laughter relationship between humor and stage fright but humor me have humor but without folly funny but true humor what does just humor me mean what humor me means when someone says humor me what does the phrase humor me mean what does it mean to humor yourself humor by generation humor by the book.com humor by the book facebook humor by country humor by exaggeration humor by sigmund freud humor by mbti humor by association humor contra vox humor contra la depresion humor contra la ansiedad humor contra el estres humor contra el calor humor contra los complejos femeninos imagens de humor contra o flamengo imagens de humor contra o corinthians humor during difficult times humor during pandemic humor during interview humor during difficult times quotes humor during coronavirus crisis humor during crisis humor during coronavirus humor during lockdown humor for seniors humor for teachers humor for dummies humor from tianheng humor from a pentecostal pew humor from the pulpit humor from australia humor from my pain
