Heat pumps play an important role more than heating. They control the humidity and provide air conditioning. During the hot season, heat pumps transfer heat from cool outdoors into the home and during the cold season, it moves the heat from houses to warm outdoors. Heat pump systems are less costly than other systems.
Types Of Energy Efficient Heat Pumps:
There are basically three main types of energy efficient heat pumps.
- Air –Source Heat Pumps
- Split-Ductless Heat Pumps
- Geothermal Heat Pumps
Air-Source Heat Pumps
This is the most common type of energy efficient heat pumps. It consists of two parts. Air handler and heat pump. An air handler is an indoor unit and a heat pump is an outdoor unit. There is a refrigerant that circulates between these units. It absorbs and releases the heat. It has the ability to reduce your heating costs by about 50%. It provides double benefits, in summer and winter.
Split-Ductless Heat Pumps
It also consists of two main units, an outdoor compressor, and an indoor handlers. These are designed for walls of the ceiling. Split-Ductless heat pumps are also known as mini splits. Both indoors and outdoor units are combined through refrigerant circulation.
These systems do not require ductwork. This efficient heat pump can avoid energy loss of more than 30%. The cost of Split-Ductless heat pumps is higher can other systems.
Geothermal Heat Pumps
Geothermal heat pumps are also known as ground and water sources. This energy efficient heat pump moves the heat through pipes buried in loops outdoor. Water in pies is warmed by 50 to 60 degrees F. Geothermal Heat Pumps control the humidity and reduce the home’s energy up to 25%. This system also requires maintenance in extreme environments.
How To Boost Up The Efficiency Of Heat Pumps
- Before buying a heat pump, consider the following points:
- Proper sealing and care also play an important role in boosting up the efficiency of heat pumps.
- Adding insulation to attic walls and adding weather stripping around the doors also increase the efficiency of the system.
- Installing the programmable thermostats lowers the temperature at night in cool days and raises the temperature in warm days. It can help you in saving 10% annual energy consumption.
What To Know Before Buy?
There is some point that must be kept in mind before purchasing energy efficient heat pumps. Like:
Heat pumps work efficiently in places without wide temperature swings and moderate heating or cooling needs. But if you want for extremely cold temperatures, then you have a need for an auxiliary heating system. It works best under 10 degrees centigrade.
Sizing is an important factor while choosing energy efficient heat pumps, because if your heat pumps are oversized or undersized. It will not work efficiently. It also increases energy bills.
- Energy Efficiency:
Normally cooling efficiency of ductless-split systems and air source is measured by SEER. SEER is known as Seasonal Energy Efficiency Ratio. 13 SEER is standard energy efficiency for homes. In a warm climate, SEER is important but in colder climate HSPF is important. The efficiency of geothermal heat pumps cooling is rated by EER and its heating is rated by COP.
