Installing solar panels on your roof makes it possible to power your air source heat pump system (and the rest of your home) with free zero-emissions electricity. The actual installation process takes one day per indoor unit, on average. This means that in the colder months, when the heat pump is likely to be relied on the most, it will use more units of electricity to produce the same amount of heating as a ground source heat pump in the same period of time. An Air Source Heat Pump (ASHP) is a system which absorbs heat from the outside air. Supply and return ducts connect to the indoor central fan. Each manufacturer stipulates their own criteria for air source heat pump servicing, which must be met in order to carry out the service correctly. This is particularly useful for property owners who experience persistently colder or warmer areas in their dwelling that they’re looking to regulate. Local installers will be able to provide more information about the incentives available to you. In the summer, a heat pump system moves heat from inside your house to an outdoor unit, efficiently cooling your home. The HSPF rates both the efficiency of the compressor and the electric-resistance elements. Conventional air source heat pumps lose their capacity as the external temperatures fall below 5 degrees Celsius (about 41 degrees Fahrenheit). Fans and compressors can be noisy, so select an air-source heat pump with a sound rating of 7.6 bels or lower. Short-run ducted is traditional large ductwork that only runs through a small section of the house. During our first year in the house, we had a carbon monoxide scare that evacuated us from our home in the middle of the night. In heating mode, liquid refrigerant in the outside coils extracts heat from the air and evaporates into a gas. Heat pump troubleshooting tips for winter icing: The unit is not defrosting. It offers the advantages of allowing the homeowner to choose from a wide variety of heating and cooling distribution systems, from radiant floor systems to forced air systems with multiple zones. You can lower your carbon footprint even further by switching all of your energy use, including your heat pumps, from fossil fuels to solar electricity. Split-system heat pumps, on the other hand, are charged in the field, which can sometimes result in either too much or too little refrigerant. CC-ASHPs (see above) may operate efficiently in temperatures as low as −30C, although they may not be as efficient in cooling during the summer season as conventional air source heat pumps. The efficiency and performance of today's air-source heat pumps is a result of technical advances such as the following: Every residential heat pump sold in this country has an EnergyGuide label, which displays the heat pump's heating and cooling efficiency performance rating, comparing it to other available makes and models. Multi-zone installations can have two or more indoor heads connected to one outdoor condenser. The indoor coils release heat from the refrigerant as it condenses back into a liquid. If your home does not have a duct system already, installing a complete duct network in your home will add a significant extra cost ($15,000 to $30,000). ASHPs can get heat from the air even when the temperature is as low as -25°C. Air Source Heat Pumps Air source heat pumps have traditionally been used in warmer climates than Alaska for both heating and air conditioning. It is common that installers will include removal and disposal of existing equipment. The system consists of a standard single speed, air-source heat pump, sized to the heating load rather than the usual smaller summer cooling load. A heat pump HSPF rates its ability to heat an area efficiently, and the SEER rates cooling efficiency. Fans and compressors make noise. Contact Blueflame today for more details. This reliable, renewable heating technology works in a highly efficient sustainable way all year round, making it the leading low carbon alternative to traditional high carbon heating systems. A heat pump system’s cost can rise quickly if your home isn’t a good fit for one, and in certain colder states heat pumps cannot provide the expected efficiency. The efficiency of an air source heat pump increases as the required flow temperature decreases. Electricity – you still need to use electricity to drive the pump, so an air source heat pump can't be considered completely zero-carbon unless this is provided by a … In colder climates, focus on getting the highest HSPF feasible. Depending on other fuel rates, it may even be the least expensive heating option among the remaining heating fuel choices. It also offers the potential for lower winter electric bills and hotter air out of the supply vents for greater comfort. An Air Source Heat Pump will have an efficiency rating of approximately 350% to 470% depending on system design and installation. Efficiency and performance deteriorate if airflow is … A heat pump has a key advantage over a conventional boiler as it can be used for more than just heating and hot water… ASHP Systems can also provide ideal living comfort in the summer. Ducted systems simply use ductwork. Ductless systems are often installed in additions. FORMER UTILITY POINT CUSTOMERS STRUGGLING TO GET CREDIT REFUNDS VIRGIN MONEY TO AXE ONLINE CREDIT CARD SERVICES NEXT MONTH - HOW IT AFFECTS YOU. Air source heat pumps also serve as a good source for air filtration and dehumidification, and can make for more comfortable living conditions for people particularly sensitive to allergens or pollutants in the air. For those replacing an oil heating system, some installers may include the removal and disposal of the oil tank, but others will charge extra for that. Jobs that are on second and third floors can also require use of special equipment that can come at an added cost. Below 40 degrees, your heat pump struggles to heat your home. Your installation cost will depend on the size of the area that you want to heat and cool. Air Source Heat Pumps Disadvantages We’ve just seen that there are many advantages when using ASHPs. There should be about 400 to 500 cubic feet per minute (cfm) airflow for each ton of the heat pump's air-conditioning capacity. What is more, heat pumps are known to work efficiently in severely cold countries such as Canada. A well-installed air source heat pump system is capable of providing 1.5 to 3 times the amount of electrical energy it consumes in the form of heat energy for your home. Copper tubing, grooved inside to increase surface area. It varies depending on where you live, but the savings are significant. At the time of this publication, the SEER of air-source heat pumps ranged from a minimum of 10 to a maximum of about 17. Air source heat pumps are a risky choice for householders trying to save money and CO2 emissions. Air-source heat pumps have been used for many years in nearly all parts of the United States, but until recently they have not been used in areas that experienced extended periods of subfreezing temperatures. Importantly, these savings will rise over time as air source heat pump technology improves and energy prices rise. ASHPs take heat from the ambient air and use electricity to “step up” the heat… In comparison to other heating and cooling technologies, air source heat pumps are quiet to operate. Did you know that Carrier is the company that was at the forefront of creating the … Another benefit to using air source heat pumps is that you have the ability to heat or cool a particular room, or zone, in your building. Also, locate the outdoor unit away from windows and … How to compare air source heat pump options, How to compare solar hot water heater options. Depending on where you live and the type of air source heat pump technology you’re installing, there may be tax credits and rebates available to decrease your upfront costs. Refrigeration systems should be leak-checked at installation and during each service call. This provides greater comfort and economy without the need for electric resistance auxiliary heating coils. Air source heat pumps (ASHPs) absorb heat from the outside air to heat both your property space and water. Their high efficiency also comes with environmental benefits – especially if you power them with solar electricity.
