Energy Efficient Heat Pump Technology

When they are powered by clean electricity (as generated by wind, solar or the use of a cleaner gas source), heat pumps can cut down on household carbon emissions from heating by up to 75 percent.

New models are more efficient today, thanks to innovations in refrigerant gases and other components. They're also getting smaller and sleeker to blend in more seamlessly with the rest of the house.

Energy Efficiency

Heat pumps are more efficient than electric resistance furnaces or other furnaces, because they make use of the air heat to heat homes instead of burning fuel. Their efficiency in energy is measured by the coefficient of performance, or COP. A high COP indicates that a single kWh of electricity can produce multiple kilowatt-hours of heat. Today, heat pumps have a COP of 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. To reduce emissions, heat pumps have to make use of renewable energy sources such as solar and wind. This will boost the efficiency of energy use by heat pumps, allowing them to be operated with less fossil fuels.

A heat pump's efficiency depends on the temperature of its two reservoirs - the indoor and outdoor storage tanks. In cooling mode the heat pump utilizes its refrigerant, and draws heat from the air to move it between storage tanks. When the system switches from cooling to heating, this flow is reversed. The outside coil is now the evaporator, while the inside coil is now the condenser. The reversing valving also reverses the direction of electrical current flowing through the fluid, which is now acting as a compressor. This increased electrical power causes the working fluid to expand, bringing the ambient heat into the house.

A heat pump can produce seven kilowatt hours of power for every kilowatt hour energy consumed. The higher the COP the more efficient it is in energy use.

As technology improves new models are being developed to suit a wider range climates. Certain models are designed to withstand freezing temperatures, while others are paired with furnaces for use in extreme climates.

Certain utilities and governments offer incentives like rebates or special electricity rates for homeowners who choose to switch to heat pumps. They are also testing ways to maximize the flexibility of these appliances by using them to store and absorb renewable energy, or by rewarding consumers for helping to shift the peak demand away from fossil fuels.

Efficiency Ratings

The consumer should take into consideration heat pump efficiency ratings. They are a great method to compare one pump with another and make sure you're buying quality equipment. The most commonly used ratings are HSPF and SEER. These ratings tell you how the performance of a heat pump during its cooling and heating seasons. Other important ratings include EER, SCOP ERP, IPLV and NPLV.

A heat pump's EER rating is an indication of how effectively it makes use of electricity to generate cooling energy. The EER rating is determined by the cooling output in relation to its electrical input. Higher ratings indicate better efficiency. When looking for a heat pump, you should start with one that has an EER rating.

It's worth investing even considering that the minimum SEER rating that is allowed currently is 13. Over time, this will result in lower energy bills and less consumption.

Generation X was born during the oil crisis and has driven the drive for more energy efficient appliances. Since 1992 the U.S. Department of Energy has established minimum standards for the SEER and HSPF ratings of heat pumps. While SEER is the most commonly used cooling rating, it's also important to look for an air conditioner that has a high HSPF rating as well.

Heat pumps with high HSPF ratings are more expensive initially but they'll be able to pay for themselves over time with substantial energy savings. They also reduce greenhouse gasses and improve the environmental quality.

There are many variables 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 with cooler supply water may reduce efficiency. This is particularly relevant if the mixing valve does not have an adjustable thermostat.

The design and insulation of the ductwork that is on the heat pump is a different aspect to take into consideration. If the ducts are poorly constructed or not insulated, they can decrease the flow of air through the heat pump and make it perform more work to reach a desired temperature. In some instances, a technician may be able fix this problem by cleaning the evaporator coil, or adjusting the refrigerant charge.

Installation

A heat pump is a central heating and air system that cools your home like an air conditioner, but also offers heating. It is a replacement for traditional heating methods, such as gas furnaces. A Carrier expert will help you choose the ideal heat pump for your climate and home.

A key advantage of a heat pump is that it is able to work effectively in moderate 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 inside your house, or the air outside your home according to the type of heat pump you select.

A heat pump's basic function is to draw the same amount of energy from the home's air that it uses to cool. This is achieved by utilizing a reversing valve to change the direction in which refrigerant flows. The heat is transferred from the air to the refrigerant by blowing air over the evaporator coil. The reversing switch then alters the flow direction to condenser. This transfers the heat to the indoor air, and the cycle begins again.

If you're thinking of installing an energy-efficient heat pump for your home, consider getting several in-home consultations with various installation companies. Compare the costs and Heat pump technology energy ratings of each company. This will give you a good idea of the prices as well as the benefits and long-term reliability of each heat pump installation.

Your local Carrier expert can help you with the installation of a brand new heat pump by properly sizing and arranging it for optimal performance. They can assess the particular requirements for cooling and heating of your space, as well as the size and condition of your ductwork. This allows them to choose the right heat pump for you and your budget.

In addition to ensuring that the heat pump is the appropriate size for your home, an HVAC professional can also advise you about making upgrades to your house to improve its energy efficiency. This will aid in saving even more energy tumble dryer with heat pump your new system. For instance, upgrading your insulation and repairing air leaks can help your heat pump last longer through winter by allowing it to draw in air from the colder outside.

Maintenance

Heat pumps, like cars require regular maintenance to ensure optimal performance. Two maintenance visits a year--once in the spring and in the fall will ensure that your system is operating properly throughout heating season. A heat pump that is not functioning properly will require more energy to achieve the same degree of comfort as a maintained system, which can result in higher monthly utility bills.

There are a number of home maintenance tasks to improve the effectiveness of your heat pump and extend its life. Cleaning your indoor air filters monthly (or replacing them with reused ones) will improve indoor air quality, and the heat pump will use less energy to circulate air. Keep outdoor units free of debris, foliage, and wildlife to prevent obstructions to airflow. This will also increase heat pump efficiency.

Another simple maintenance step to remember is to check a heat pump for tripped circuit breakers or fuses as well as blown fuses, which could be caused by an electrical overload or ignition problem that requires professional attention. In addition, it is important to test your thermostat frequently to ensure it's operating at appropriate temperature and is not sending the system into overdrive.

If you hear strange sounds emanating from your heat pump It's usually a sign that the air ducts have become blocked or the blower fan is dirty. This requires professional assistance. It is a good idea to clean the evaporator coils periodically. This will decrease dust accumulation and improve airflow. Also, making sure that the condensate drain is free of obstructions can stop water leaks, blockages and potential fire hazards.

The cost of maintenance and repairs will vary depending on the type of system you have and the age of the system and how easy it is for a licensed technician to work on. Repairing smaller systems that and cool a single room is less expensive than large units which provide air conditioning for the whole home. In addition, the accessibility of a heat pump located in a crawl space can affect both repair and maintenance charges per hour.
