Ten Heat Pump Technology Myths You Shouldn't Post On Twitter
Energy Efficient Heat Pump Technology

When they are powered by clean electricity (as generated by wind, solar or an alternative source of gas that is cleaner) heat pumps can cut down on the carbon emissions of heating homes by about 75 percent.

New models are more efficient today due to the advancements in refrigerant gas as well as other components. They're also getting smaller and more sleek, meaning they blend better with the home.

Energy Efficiency

Heat pumps are more energy efficient than electric resistance or other furnaces due to the fact that they draw heat from the air to heat homes, instead of creating their own heat by burning fuel. Their efficiency in energy can be measured by the coefficient performance (COP). A high COP indicates that one unit of electricity can produce a large number of kilowatt hours of heat. Today, heat pumps have a COP of around four. This means that a single kWh could generate four kWh.

Heat pumps can reduce carbon emissions by heating buildings in cold climates. But to truly reduce emissions, it's important to ensure that the electricity that heat pumps use comes from renewable sources such as wind and solar. This will increase the efficiency of energy used by heat pumps and allow them to operate with less fossil fuels.

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 utilizes its refrigerant, and draws air heat to transfer between the storage tanks. When the system changes from cooling to heating the flow of heat is reversed. The outside coil becomes the evaporator, while the inside coil is the condenser. The reversing valve also alters the direction of the electrical current flowing through the working fluid which is now acting as a compressor. The increased electrical power causes the working fluid to expand, bringing the heat of the surrounding area into the home.

A heat pump is able to produce seven kilowatt hours of power for every kilowatt-hour of energy consumed. The higher the COP, the more efficient it is on energy.

As heat pump tumble dryers , more models are being developed to suit a wider range climates. Certain models are designed to withstand freezing temperatures while others are equipped with furnaces that can be used in extreme conditions.

Certain utilities and governments provide incentives, such as discounts or special rates on electricity for homeowners who make the switch to heat pumps. There are also efforts to maximize the flexibility of these appliances by utilizing them to store and absorb renewable energy or by rewarding consumers who help shift peak demand away from fossil fuels.

Efficiency Ratings

The consumer should take into consideration the efficiency ratings of heat pumps. They are a great way to compare a heat pump to another and ensure sure you're purchasing the highest quality equipment. The most popular ratings are HSPF and SEER. These ratings tell you how well a heat pump performs during its heating and cooling seasons. Other useful ratings include EER, SCOP, ERP IPLV, NPLV and EER.

The EER rating of the heat pump is a measure for how efficiently it uses electricity to create cooling. This is determined by the proportion of its cooling output to its electrical input and higher ratings mean higher efficiency. The best place to start when searching for a brand new heat pump is with one that has an EER rating of high.

It's worth investing even when the minimum SEER rating permitted currently is 13. As time passes, this will result in lower energy bills and consumption.

Generation X was born during the oil crisis and has been driving the push for more efficient appliances that are energy efficient. Since 1992, the U.S. Department of Energy set the minimum standards for heat pumps that have HSF and SEER ratings. While SEER is the most frequently used cooling rating, it's crucial to select a heat pump that has an HSPF rating that is high as well.

Heat pumps with high HSPF ratings are more expensive at first, but will be able to pay for themselves over time with substantial energy savings. They will also reduce greenhouse gas emissions and help improve the environmental quality.

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 instance, that allows warmer return water to mix in with cooler supply water could lower efficiency. This is especially true if it doesn't have a thermostatic mixing valve.

The design and insulation of the ductwork on the heat pump is a different aspect to be considered. If the ducts are not properly constructed or not insulated, they can decrease the heat pump's airflow and force it to be more difficult to reach the desired temperature. In some instances, the technician may be able to correct the issue by cleaning the evaporator, or changing the refrigerant charges.

Installation

A heat pump is an air and heating system that cools your house like an air conditioner, but also provides heating. It is a replacement for traditional heating methods, like gas furnaces. A Carrier expert can help you select the right heat pump for your home and the climate.

The heat pump has the benefit of working in mild climates. This is not the case for other heating systems. The heat pump utilizes ambient air to heat the room. The air is drawn from the ground, air inside your home, or air outside, based on the kind of heat pump is chosen.

The primary function of a heat pump is to draw the same amount of energy from the home's air as it does to cool. It accomplishes this by using a reversing valve to change the direction of the flow of refrigerant. Air is blown through an evaporator coil, which transports the heat from the air to the refrigerant. The reversing valve changes the direction of the flow to a condenser coil. This transfers the heat to the air inside and the cycle starts again.

Consider getting several in-home consultations with different installation companies if you're considering an electric heat pump. Compare the prices and energy ratings of each. This will give a good idea about the cost and benefits as well as the reliability of each installation.

Your local Carrier expert can assist you in the installation of a new heat pump by properly sizing and arranging it for maximum performance. They can evaluate the specific heating and cooling requirements of your home, as well as the size and condition of your ductwork. This allows them to select the best heat pump for your needs and budget.

A HVAC professional can help you improve your home to increase its energy efficiency. This will allow you to get even greater savings on energy costs from your new system. The latest insulation and air leaks, for instance, can enable your heat pump to continue to run longer in winter. This is because it can draw air from the colder outside.

Maintenance


Similar to your car, heat pumps need regular tune-ups to ensure maximum performance. Two regular maintenance visits per year--once in the spring and in the fall will help your system work properly throughout the heating season. A heating system that does not function properly will likely need to use more energy to attain the same comfort level as a well-maintained system, which will result in higher utility costs every month.

In addition to a routine examination by a licensed technician, there are many home maintenance tasks you can complete yourself to boost efficiency and extend the life of your heat pump. For instance cleaning your indoor air filter on a regular basis (or replacing reusable filters) can improve the quality of indoor air and keep the heat pump running less frequently to circulate the same amount of air. Keep the outdoor units free of debris, foliage, and wildlife to prevent obstructions to airflow. This can also improve the efficiency of your heat pump.

A simple task to do is to check your heat pump on a regular basis for damaged fuses or circuit breakers. These could be the result an electrical overload or an ignition issue that requires expert attention. It is also essential to check the thermostat on a regular basis to ensure that it's operating at the right temperature and not causing the system to overdrive.

If you experience strange noises emanating from your heat pumps is usually a sign that the air ducts are blocked or the blower fan is dirty. This requires professional assistance. It is a good idea to clean the evaporator coils regularly. This will help reduce dust accumulation and improve airflow. Also, making sure that the condensate drains are free of obstructions will help stop water leaks, blockages and potential fire hazards.

Repair and maintenance costs vary according to the type of system you have as well as its age and how easily accessible it is to a technician. Repairing smaller systems that and cool one space is less costly than larger units which provide cooling for the entire house. In addition, having access to a heat pump that is located in a crawlspace will impact repair and maintenance fees per hour.
