15 Things You Didn't Know About Heat Pump Technology
Energy Efficient Heat Pump Technology


When powered with clean electricity (as generated by solar, wind 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.

Today, advances in refrigerant gases as well as other components mean that the latest models are more efficient. They're also getting smaller and sleeker, blending into the home.

Energy Efficiency

Heat pumps are more efficient than electric resistance furnaces or other furnaces because they make use of the heat in the air to heat homes, instead of burning fuel. Their efficiency in energy is measured by the coefficient of performance or COP. A high COP means that an electricity unit can generate multiple kilowatts of heat. Heat pumps today have a COP of around four. This means that one kWh can produce four kWh.

This means that even in cold climates heat pumps have the potential to drastically reduce carbon emissions from heating buildings. However, to reduce emissions, it's essential to ensure that the power that heat pumps use comes from renewable sources such as wind and solar. This will increase the overall efficiency of heat pump systems, allowing them to operate them using less fossil fuels, and lower greenhouse gas (GHG) emissions.

The efficiency of a pump is determined by the temperature of its two reservoirs, the outdoor and the indoor storage tanks. In cooling mode the heat pump makes use of its refrigerant and pulls air heat to transfer between the storage tanks. When the system shifts from heating to cooling the flow of heat is reversed. The outside coil becomes the evaporator and the inside coil acts as the condenser. The reversing valving reverses the direction of electrical current that flows through the fluid which is now acting as a compressor. The power generated by the increased electrical current causes the working fluid to expand, pushing the temperature of the room.

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

As the technology advances and new models are developed, they are designed to cater to a wider range of climates in mind. Some have been built to withstand freezing temperatures, while others are paired with furnaces for use in the most severe conditions.

Some utilities and governments offer incentives to homeowners who switch from heat pumps to heat pumps, like rebates. And some are testing ways to make the most of the flexibility of these appliances by utilizing them to store and absorb renewable energy, or by rewarding consumers for helping to shift their peak demand away fossil fuels.

Efficiency Ratings

Consumers should consider heat pump efficiency ratings. They are a great way to compare one heat pump with another and make sure you're purchasing the highest quality equipment. The most common ratings are SEER and HSPF. These ratings indicate 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 measurement for how efficiently it utilizes electrical energy to produce cooling. This is determined by the proportion of its cooling output to its electrical input and higher ratings mean higher efficiency. When you are looking for a new heat pump, you should start with one that has an EER rating.

Although the minimum SEER that is allowed today is 13, it's worth investing in a model that has higher ratings. Over time this will result in lower energy bills and less consumption.

Generation X was born during the oil crisis, and have been the driving force behind the push for more efficient appliances. Since 1992 the U.S. Department of Energy has established minimum standards for the SEER and HSPF ratings for heat pumps. While SEER is the most frequently used cooling rating, it's also important to look for heat pumps that have high HSPF ratings as well.

Heat pumps with high HSPF ratings are more expensive initially however they will be able to pay for themselves over time with significant energy savings. They also help reduce greenhouse gas emissions and help improve the environmental quality.

Numerous factors can affect the efficiency of energy used by a heat pump in relation to its size, as well as the location it is placed 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 the case if it does not have a thermostatic mixing valve.

The design and insulation of the ductwork on the heat pump is a different aspect to take into consideration. If the ducts are poorly constructed or not insulated they could decrease the flow of air through the heat pump and cause it to work harder to achieve a desired temperature. In some instances the technician might be able correct this problem by cleaning the evaporator, or altering the refrigerant charge.

Installation

A heat pump is an air conditioning and heating system that can cool your home much like an air conditioner. It replaces traditional heating methods, such as gas furnaces. A Carrier expert can help you select the right heat pump for your home and climate.

The main benefit of a heat pump is that it is able to work effectively in moderate temperatures, in contrast to other heating systems. The heat pump makes use of ambient air to warm the room. This air can be drawn from the ground, the air inside your home, or the air outside of your home, depending on the type of heat pump you choose.

The primary function of a heat pump is to draw the same amount of energy from the home's air that it uses to cool. It accomplishes this by using a reversing valve to change the direction of the flow of refrigerant. The heat is transferred from the air into the refrigerant by blowing air across the coil that evaporates. The reversing valve then changes the direction of the flow to a condenser coil. The heat is then transferred to the indoor air, and the cycle starts again.

If you're thinking of installing the installation of a heat pump in your home, think about getting several in-home consultations with different installation companies. Then, compare the prices and energy efficiency ratings that each company offers. This will give you an idea of the cost and benefits as well as the long-term reliability of each heat pump installation.

Your local Carrier expert will assist you to install a new heat-pump by properly sizing it and arranging it for optimal performance. They can assess the particular heating and cooling requirements of your space, as the condition and size of your ductwork. This allows them to choose the best heat pump for your needs and budget.

A HVAC professional can help you make improvements to your home to improve its efficiency in energy use. This can help you get even greater savings on energy costs from your new system. The latest insulation and air leaks, like, can enable your heat pump to continue to run longer in winter. This is due to the fact that it draws ambient air from the colder weather outside.

Maintenance

Similar to your car, heat pumps need regular maintenance to ensure their performance is at its best. tumble dryers with heat pump per year, one in the spring and one in the fall, will help your system function properly during heating season. A heating system that is not functioning correctly will require more power to attain the same level of comfort as a properly maintained system, leading to higher monthly utility bills.

You can do several home maintenance tasks to improve the efficiency of your heating system and extend its life. For example cleaning your indoor air filter monthly (or replacing it with reusable filters) will improve the quality of your indoor air and ensure that the heat pump is working less hard to circulate the same amount of air. Keeping outdoor units clear of foliage, debris and animals can also reduce airflow obstructions and increase the efficiency of your heat pump.

A simple maintenance task is to check your heat pump on a regular basis for blown fuses or circuit breakers. They could be the result of an electrical overload, or an ignition issue that requires professional attention. It is also essential to check the thermostat on a regular basis to ensure it's functioning at the right temperature and not leading to the system to go into overdrive.

If you hear unusual noises emanating from your heating system It's usually an indication of a blocked air duct or dirty fan that will require professional service. It's a good idea also to clean the evaporator coils regularly. This will decrease dust build-up and increase airflow. Make sure that the condensate drain is free of debris to prevent blockages, leaks and fire hazards.

Maintenance and repair costs can vary depending on your system and its age, as well as how easily accessible it is to a technician. Repairing smaller systems that only heat and cool a single room is less expensive than large units that supply cooling for the entire house. Access to a heat-pump located in a crawlspace will also impact the repair and maintenance costs.
