Energy Efficient Heat Pump Technology When powered with clean electricity (as generated by solar, wind or the use of a cleaner gas source) heat pumps can cut down on the carbon emissions of heating homes by up to 75 percent. Today, advances in refrigerant gases as well as other components mean that the new models are more efficient. They're also getting smaller and more sleek, meaning they blend better with the interior of your home. Energy Efficiency They are more efficient than electric resistance furnaces or other furnaces because they make use of the heat of the air to warm homes, instead of burning fuel. Their energy efficiency can be measured by the coefficient performance (COP). A high COP indicates that one kWh of electricity will provide multiple kilowatt-hours of heat. In general, today's heat pumps have COPs that are approximately four, which means that a single kWh of electricity can produce four kWh of heat. This means that, even in cold climates heat pumps are able to significantly reduce carbon emissions from heating buildings. To cut down on emissions, heat pumps need to make use of renewable energy sources like solar and wind. This will improve the overall efficiency of heat pump systems, which will allow them to operate them using less fossil fuels, and lower greenhouse gas (GHG) emissions. The efficiency of a heat pump is contingent on the temperature of its two reservoirs – the outdoor and indoor storage tanks. In cooling mode the heat pump draws in heat from the air and uses its refrigerant in order to transfer it between the storage tanks and the house. When the system is switched to heating, it reverses the flow. The outside coil is now the evaporator while the inside coil is now the condenser. The valve that reverses the direction of flow also changes the direction of the electrical current flowing through the working fluid which acts as a compressor. The power generated by the increased electrical current causes the working fluid to expand, pushing up the ambient heat inside the house. A heat pump can produce seven kilowatts of electricity for every kilowatt hour energy used. heat pump tumble dryers is on energy. As the technology advances and new models are developed, they are designed with a wider range of climates in mind. Some have been built to resist freezing temperatures, while others are paired with furnaces to be used in extreme climates. Some utilities and governments offer incentives to homeowners who make the switch from heat pumps to heat pumps, for example rebates. They are also experimenting with ways to maximize the flexibility of these appliances by using them to store and absorb renewable energy, or by rewarding consumers for helping shift peak demand from fossil fuels. Efficiency Ratings Consumers should consider the efficiency ratings of heat pumps. They're a good way to compare a heat pump to another and make sure you're buying the best quality equipment. The most popular ratings are SEER and HSPF. These rates tell how the heat pump performs in its cooling and heating seasons. Other useful ratings include EER, SCOP ERP, NPLV and IPLV. The EER rating of a heat pump is a measurement for how efficiently it uses electricity to create cooling. This is determined by the ratio of its cooling output to its electrical input and higher ratings mean more efficiency. A good place to start when shopping for a new heat pump is to choose one with an EER rating that is high. While the minimum SEER allowed currently is 13 points, it's worth investing in a model that has an even higher rating. This will result in lower energy costs and reduced energy consumption in the long run. Generation X was born during the oil crisis and has driven the drive for more efficient appliances that are energy efficient. Since 1992 the U.S. Department of Energy has established minimum standards for SEER and HSPF ratings for heat pumps. While SEER is typically used to determine cooling ratings, you should also look for heat pumps with an HSPF rating that is high. Heat pumps with an HSPF rating that is high will be more expensive upfront, but they'll be able to pay for themselves through significant energy savings over the course of time. They'll also help to reduce greenhouse gas emissions as well as improve the environmental quality. Numerous factors can affect the energy efficiency of a heat pump such as its size and where it is installed within the home. A buffer tank, for instance one that allows warmer return water to mix with cooler supply water may lower efficiency. This is particularly true if it doesn't have an automatic mixing valve. Another aspect to consider is how a heat pump's ductwork has been designed and constructed and insulated. The heat pump will need to work harder if the ducts do not perform as they should or are not insulated. In some instances the technician might be able to correct the issue by cleaning the evaporator, or adjusting refrigerant charges. Installation A heat pump is an heating and air conditioning system that is able to cool your home, similar to an air conditioner. It replaces traditional heating methods such as gas furnaces. A Carrier expert can help you choose the best heat pump for your home and climate. The heat pump has the advantage of working in mild climates. This is not true for other heating systems. The heat pump uses ambient air to warm the room. This air can be drawn from the ground, the air inside your house, or the air outside of your home, depending on the type of heat pump you select. A heat pump's basic function is to draw the same amount of energy from your home's air that it uses to cool. This is done by utilizing a reversing valve to change the direction that the refrigerant flows. The heat is transferred from the air into the refrigerant by blowing air over the coil that evaporates. The reversing valve changes the direction of the flow to a condenser coil. This heat is then transferred to indoor air and the cycle is then initiated again. If you're thinking about a heat pump for your home, consider getting a few in-home consultations from various companies that install the system. Compare the prices and energy ratings of each company. This will give you an idea of the prices as well as the benefits and long-term reliability of each heat pump installation. Your local Carrier expert can assist you with the installation of a new heat pump by sizing it correctly and positioning it for the best performance. They can evaluate the specific requirements for cooling and heating of your home, as well the size and condition of your ductwork. This helps them select the ideal heat pump for your home and budget. A HVAC professional can assist you to improve your home to improve its efficiency in energy use. This will help you save even more energy with your new system. For instance, enhancing your insulation and fixing air leaks could make your heat pump run more throughout winter, allowing it to draw in ambient air from the colder outside. Maintenance Heat pumps, like cars, need regular maintenance to ensure their performance is at its best. Two maintenance visits a year – once in spring and once in fall—will aid in the proper functioning of your system throughout the heating season. A heat pump that does not work properly will need to use more energy to achieve the same level of comfort as a well maintained unit, which will result in more expensive monthly bills for utilities. You can perform a variety of home maintenance tasks to improve the effectiveness of your heat pump and extend its lifespan. Cleaning your air filters in the indoors each month (or replacing them with reusable ones) will improve the indoor air quality, and the heat pump will work less to circulate air. Clearing outdoor units of foliage, debris and wildlife can also prevent obstructions to airflow and boost the efficiency of your heat pump. Another simple step to keep in mind is to inspect your heat pump for tripped circuit breakers or fuses and fuse blows, which could be the result of an electrical overload or ignition problem that needs professional attention. In addition, it is essential to check your thermostat on a regular basis to ensure it's operating at proper temperature and not putting the system into overdrive. If you hear unusual noises coming from your heat pump It's usually a sign of a clogged air duct or dirty fan that requires professional service. It's recommended to periodically clean the evaporator coils, which will reduce dust accumulation and increase airflow. Finally, ensuring the condensate drain is free of obstructions will help stop water leaks, blockages and potential fire hazards. The cost of maintenance and repairs will vary depending on the kind of system you own and the age of the system and how easy it can be for a licensed technician to work on. Repairing smaller systems that and cool one room is less costly than larger units which provide air conditioning for the entire house. Additionally, access to the heat pump in a crawlspace will affect both repair and maintenance charges per hour.
