Energy Efficient Heat Pump Technology

Heating systems that are powered by clean electricity (such as wind, solar, or a cleaner gas source) can cut down on CO2 emissions from heating by as much as 75 percent.

New models are more efficient now thanks to advances 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

They are more efficient in energy use than electric resistance or other furnaces due to the fact that they utilize ambient heat from the air to heat homes, as opposed to generating their own heat by burning fuel. Their efficiency in energy can be measured using the coefficient performance (COP). A high COP indicates that a single kWh of electricity can produce many kilowatt hours of heat. In general, the current heat pumps have COPs of about four, which means that a single kWh of electricity can generate four kWh of heat.

This means that even in cold climates, heat pumps are able to drastically reduce carbon emissions from heating buildings. But to truly reduce emissions, it is essential to ensure that the power used by heat pumps is from renewable sources, such as wind and solar. This will boost the energy efficiency of heat pumps and allow them to run on less fossil fuels.

The efficiency of a pump depends on the temperature of its two reservoirs, the indoor and the outdoor storage tanks. In cooling mode the heat pump makes use of its refrigerant, and draws air heat to move between the storage tanks. When the system shifts to heating, it reverses this flow. The outside coil is now the evaporator, whereas the inside coil functions as a condenser. The reversing valve also reverses the direction of electrical current flowing through the fluid, which is now acting as a compressor. The power generated by the increased electrical current causes the working fluid to expand and push 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 used. The higher the COP, the more efficient it is on energy.

As technology improves new models are being developed to accommodate a wider variety of climates. Some are built to withstand freezing temperatures, while others are combined with furnaces for use in the harshest conditions.

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

Efficiency Ratings

Consumers should be aware of heat pump efficiency ratings. They are a great way to compare a heat pump to another and make sure you're purchasing the highest quality equipment. The most common ratings are HSPF and SEER. These ratings tell you how well a heater performs in the heating and cooling seasons. Other helpful ratings are ERP, EER, SCOP, NPLV, and IPLV.

The EER rating of a heat pump is a measure for how efficiently it uses electrical energy to produce cooling. This is determined by the proportion of its cooling output to its electrical input which is higher, indicating greater efficiency. When looking for a heat pump, begin with one that has an EER rating.

Although the minimum SEER that is allowed today is 13 points, it's worth investing in a model with an even higher rating. Over time this will result in lower energy bills and consumption.

Generation X were born during the oil crisis, and they've been the driving force behind the demand for more efficient appliances. Since 1992 the U.S. Department of Energy established the minimum standards for heat pumps' SEER and HSF ratings. While SEER is most commonly used to determine cooling ratings but you should also look for heat pumps with an HSPF rating that is high.

Heat pumps with high HSPF ratings are more expensive at first however they will pay for themselves in the long run with significant energy savings. They also reduce greenhouse gasses and improve the environment.

There are many factors that affect a heat pump's energy efficiency, including its size and how it's installed in the home. A buffer tank, for example one that allows warmer return water to mix in with cooler supply water may reduce efficiency. This is especially relevant if the mixing valve doesn't have a thermostatic setting.

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 not properly designed or uninsulated, they can decrease the heat pump's airflow and force it to work harder to achieve the desired temperature. In some instances the technician might be able to correct this issue by cleaning the evaporator coil or heat pump technology adjusting the refrigerant charge.

Installation

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

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. This air can be drawn from the ground, the air inside your home, or from the air outside your house dependent on the kind 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 as it does to cool. This is achieved by utilizing a reversing valve to alter the direction in which the refrigerant flows. The heat is transferred from the air into the refrigerant by blowing air over the evaporator coil. The switch that reverses it alters the flow direction to condensers. The heat is then transferred to indoor air and the cycle is then initiated again.

Consider getting several in-home consultations with various installation companies if you're considering a heat pump. Compare the costs and energy ratings of each company. This will give you a good idea of the prices, 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 correctly sizing and positioning it for maximum performance. They can assess the heating and cooling needs of your home as well as the size, condition and the age of your ductwork. This helps them select the ideal heat pump for your home and budget.

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

Maintenance

Heat pumps, like cars require regular maintenance to ensure their performance is at its best. Two maintenance visits a year - one in spring and once in fall--will ensure that your system is operating properly throughout the heating season. A heat pump that fails to work correctly will likely need to use more energy to attain the same level of comfort as a well-maintained system which will result in higher utility costs each month.

In addition to a routine checkup by a licensed technician, there are a variety of home maintenance tasks you can do yourself to boost efficiency and extend the life of your heat pump. For example cleaning your air filter monthly (or replacing reusable filters) will improve indoor air quality and ensure that the heat pump is operating less efficiently to circulate the same amount of air. Cleaning outdoor units of leaves, debris and wildlife can also prevent airflow obstructions and increase the efficiency of your heat pump.

A simple task to do is to check your heating system regularly for blown fuses and circuit breakers. They may be the result of an electrical overload, or an ignition problem that requires professional attention. In addition, it is essential to check your thermostat regularly to ensure that it is operating at the appropriate temperature and is not sending the system into overdrive.

If you hear strange sounds coming from your heat pumps, it's often an indication that the air ducts are blocked or the blower fan is dirty. This may require professional service. It is recommended to clean your evaporator coils, which can reduce dust accumulation and increase airflow. Also, making sure that the condensate drain is free of obstructions will help prevent blockages, water leaks and potential fire hazards.

The cost of maintenance and repairs will vary depending on the type of system you own, how old it is and how accessible it can be for a licensed technician to work on. For instance, smaller systems designed to heat and cool a single room are generally cheaper to repair than large units that provide conditioning for the entire house. Access to a heat-pump tumble dryer located in a crawlspace could influence the cost of maintenance and repair.
