Energy Efficient Heat Pump Technology Heating systems that are powered by clean electricity (such as wind, solar, or a cleaner source of gas) can cut down on CO2 emissions from heating by as much as 75 percent. New models are more efficient today due to the advancements in refrigerant gas and other components. And they're getting smaller and sleeker to blend in more seamlessly with the home. Energy Efficiency Heat pumps are more energy efficient than electric resistance or other furnaces since they utilize ambient heat from the air to heat homes, instead of producing their own heat through burning fuel. Their energy efficiency is measured using the coefficient of performance, or COP. A high COP indicates that one kWh of electricity can produce several kilowatt-hours of heating. Heat pumps today have a COP around four. This means that one kWh can produce four kWh. This means that even in cold climates heat pumps can be used to significantly reduce carbon emissions from heating buildings. However, to reduce emissions, it's important to ensure that the power used by heat pumps comes from renewable sources such as wind and solar. This will boost the efficiency of energy used by heat pumps which will allow them to be operated with less fossil fuels. A heat pump's efficiency depends on the temperature of its two reservoirs, the outdoor and indoor storage tanks. In cooling mode, the heat pump pulls in heat from the atmosphere and uses its refrigerant to move it between the storage tanks and the house. When the system switches from heating to cooling the flow is reversed. The outside coil becomes the evaporator and the inside coil is now the condenser. The reversing valving reverses the direction of electrical current flowing through the fluid that is now acting as a compressor. The power generated by the increased electrical current causes the working fluid to expand and push the heat from the outside into the house. A heat pump can generate seven kilowatt hours of power for every kilowatt-hour of energy consumed. And the higher the COP, the more energy efficient it is. As technology advances, more models are being designed to accommodate a wider variety of climates. Certain models are made to withstand freezing temperatures, whereas others have furnaces built in to withstand the most extreme climates. Certain utilities and governments provide incentives, such as discounts or special rates on electricity for homeowners who choose to switch to heat pumps. Some are also testing ways to harness the power of these appliances by using them to store and absorb renewable energy, or by rewarding consumers who help shift the peak demand away from fossil fuels. Efficiency Ratings The efficiency ratings of heat pumps are an important consideration for buyers. These ratings can be a great way to compare heat pumps and ensure you're getting the best equipment. The most commonly used ratings are SEER and the HSPF. These ratings indicate how well a heatpump works in the heating and cooling seasons. Other important ratings include SCOP ERP, EER, NPLV and IPLV. The EER rating of the heat pump is a measurement of how effectively it uses electrical energy to produce cooling. This is determined by the proportion of its cooling output to its electrical input and higher ratings mean greater efficiency. When shopping for a heat pump, begin with one that has an EER rating. The minimum SEER permitted currently is 13 SEER, it's worthwhile to invest in a model that has higher ratings. This will result in lower energy costs and reduced energy consumption in the long run. Generation X was born in the middle of the oil crisis, and have been the driving force behind the demand for more efficient appliances. Since 1992, the U.S. Department of Energy set minimum standards for heat pump' SEER and HSF ratings. While SEER is the most widely used cooling rating, it's important to choose an air conditioner that has high HSPF ratings as well. Heat pumps with an HSPF rating of high will cost more initially, but they'll pay for themselves with significant energy savings over the course of time. They also aid in reducing greenhouse gas emissions and help improve the environment. There are a variety of factors that can affect a heat pump's energy efficiency, including its size and how it's installed in the home. A buffer tank, for example, that allows warmer return water to mix in with cooler supply water may decrease efficiency. This is particularly relevant if it doesn't include a thermostatic mixing valve. The design and insulation of the ductwork that is on the heat pump is an additional aspect to be considered. The heat pump will need to perform more efficiently in the event that the ducts fail to work properly or aren't insulated. In some cases, the technician may be able correct this problem by cleaning the evaporator or adjusting refrigerant charges. Installation A heat pump is a central heating and air system that cools your home just like an air conditioner and also offers heating. It replaces traditional heating methods like gas furnaces. A Carrier expert will assist you choose the ideal heat pump for your climate and home. A key advantage of a heat pump is that it is able to be effective in mild climates, unlike other heating systems. This is because the heat pump draws in ambient air to provide warmth. The air could come from the ground, the air in your house, or the air outside of your home, depending on the type of heat pump you select. The main function of a heat pump is to draw the same amount of energy from the home's air that it uses for cooling. This is done by using a reversing valance to alter the direction in which refrigerant flows. The air is blown across an evaporator coil that transports the heat from the air to the refrigerant. The reversing valve then changes the direction of the flow to condenser coil. heat-pump tumble dryer to the air inside and the cycle starts again. Consider getting several in-home consultations from different installation companies if you're considering the installation of a heat pump. Compare the costs and energy efficiency ratings that each company provides. This will give a good idea of the costs as well as the benefits and reliability of each heat pump installation. Your local Carrier expert will help you install a new heat-pump by properly sizing it and arranging it for maximum performance. They can assess the cooling and heating requirements of your space and also the size, condition and the age of your ductwork. This allows them to choose the right heat pump for your needs and budget. A HVAC professional can help you improve your home to increase its energy efficiency. This can help you save even more energy by implementing a new system. For instance, enhancing your insulation or fixing air leaks can make your heat pump last longer into the winter by allowing it to draw in air from the colder outdoor. Maintenance Just like your car, heat pumps need regular maintenance to ensure their performance is at its best. Two maintenance visits per year, one in spring and the other in the fall, will ensure that your system function properly during heating season. A heat pump that is not functioning correctly will require more power to attain the same degree of comfort as a maintained unit, which will result in more monthly utility bills. In addition to a regular inspection by a certified technician, there are many home maintenance tasks you can do yourself to improve efficiency and extend the life of your heat pump. For example cleaning your air filter every month (or replacing it with reusable filters) will improve indoor air quality and ensure that the heat pump is running less frequently to circulate the same amount of air. Keep the outdoor units free of debris, foliage and wildlife to prevent airflow obstructions. This can also improve heat pump efficiency. Another simple maintenance step to be aware of is to check a heat pump for tripped circuit breakers or fuses as well as blown fuses, which could be the result of an electrical overheat or ignition issue that requires expert attention. Additionally, it's important to test your thermostat regularly to make sure that it's operating at proper temperature and not putting the system into overdrive. If you hear strange noises emanating from your heat pump It's usually a sign of a clogged air duct or dirty blower fan that will require professional service. It is recommended to periodically clean the evaporator coils, which can reduce dust accumulation and increase airflow. Make sure that the condensate drainage is free of debris to prevent blockages and leaks, as well as fire hazards. The cost of maintenance and repairs will vary depending on the kind of system you have and the age of the system and how accessible it can be for a licensed technician to work on. Repairing smaller systems that only heat and cool one space is less expensive than large units which provide air conditioning for the entire house. Access to a heat-pump located in a crawlspace could impact the repair and maintenance costs.
