What is a heat pump?
</p>
<p>
</p>
<p>
A heat pump is a HVAC system that uses electricity to provide heating and cooling. It is a system like that of a refrigerator or air conditioner. It evaporates liquid refrigerant which absorbs heat, which includes the air surrounding it. This heat is then transferred into the through a series of metal coils and fan.

use much less energy than furnaces, boilers or electric radiators to generate heat since they get their thermal energy from air and the ground, rather than generating it through electrical resistance or combustion.
</p>
<p>
</p>
<p>
A heat pump functions as an air conditioner operating in cooling mode, taking in heat from the air outside even when it is cold and transferring it into. It can also serve as a heater during winter when a reversing switch turns off the flow, changing the refrigerant back into liquid before evaporating. The heat is then dragged into the unit via a fan and the copper tubes inside the indoor unit.
</p>
<p>
</p>
<p>
The heat pumps can generate two to three times more energy than the electricity they use which makes them more energy efficient than traditional furnaces and boilers. They can be used to heat your entire home or just a small area like garages or an attic.
</p>
<p>
</p>
<p>
A variety of innovations are helping make heat pumps more efficient. These include variable speed compressors that operate at close to full capacity most of the time, instead of continuously cycling on and off, and scroll compressors that are quieter and more efficient than traditional compressors. Other efficiency-boosting features are a desuperheater that heats water by using waste refrigerant. Zone control systems also offer heating for each room within the home.
</p>
<p>
</p>
<p>
The fact that heat pumps can be powered by renewable energy sources is their biggest innovation. This reduces the environmental impact of the pumps, since they do not use fossil fuels to power them. They also utilize low-global-warming-potential (GWP), which is more sustainable for the environment, as opposed to R-410A or other hydrocarbons.
</p>
<p>
</p>
<p>
How does a heatpump work?
</p>
<p>
</p>
<p>
A heat pump extracts heat1 from the air, ground, geothermal energy, or other sources and then transfers it to your home, supplying both cooling and heating. It is a green alternative to conventional electric or gas systems. It also requires less maintenance than traditional systems.
</p>
<p>
</p>
<p>
The technology behind the technology behind a heat pump is comparable to that of an air conditioner. The system includes two major components which are an outdoor unit (which looks like the outside component of a split-system air conditioning system) and an indoor unit that includes a coil that can serve as an evaporator or condenser. The system contains a fan which is able to blow air across the coil to aid in the transfer of heat. The refrigerant contained in the coil is liquid at temperatures of room temperature, but once it gets hot inside the house, it vaporizes into a gas. A reversing valance close to the compressor can change the direction of refrigerant flow to cooling and heating modes.
</p>
<p>
</p>
<p>
Because heat naturally moves to regions with lower temperatures and lower pressure The vapor refrigerant within the coil absorbs warmth from the air inside your home. Then, it is moved to the outdoor unit where a compressor boosts the pressure and raises the temperature further. This causes the boiling point of the liquid to decrease, and it returns to the state of liquid.
</p>
<p>
</p>
<p>
As the refrigerant liquid exits the compressor, it goes through another coil that is located in the outdoor unit. This coil is called an evaporator if the heat pump is heating, and condenser when it's cooling. The outdoor coil makes use of series of aluminum fins that transfer heat from the air.
</p>
<p>
</p>
<p>
The evaporator in the indoor heat pump has a fan that blows air over the copper or aluminum coils, which have grooved inside surfaces to increase surface area and help in transferring heat. The fan keeps the air moving at a steady speed to minimize drafts and decrease noise. Some models have a desuperheater that recovers the heat of the evaporator when it is in cooling mode and uses that heat to efficiently heat water.
</p>
<p>
</p>
<p>
What are the benefits of the use of a heatpump?
</p>
<p>
</p>
<p>
Heat pumps are the most eco-friendly HVAC system when it comes to saving money and reducing your environmental impact. As state and local governments continue to offer rebates and incentives to homeowners who choose to switch, this climate-friendly technology continues to gain popularity. The Department of Energy touts their advantages over traditional heating methods.
</p>
<p>
</p>
<p>
As opposed to gas furnaces pumps use metal coils and fans to transfer energy from the air. Since they don't use fuel, unlike combustion heaters they don't emit any emissions or other pollutants. They don't require a chimney for exhaust fumes to be vented out of the house. Additionally, heat pumps are extremely quiet - they operate at just a fraction of the sound levels of gas furnaces.
</p>
<p>
</p>
<p>
A new study by UC Davis found that a heat pump that operates on clean electricity (generated by wind, solar or other renewable sources) could cut household carbon dioxide emissions by up to 75 percent. However, the research only focused on houses with superior insulation and a modern heating system, not all households.
</p>
<p>
</p>
<p>
It's a good idea to know that heat pumps are able to be retrofitted into most existing homes. If you are looking to upgrade your home we suggest that you speak with your local public power or cooperative district. They can provide information on contractors as well as financing and other aspects of this exciting new technology.
</p>
<p>
</p>
<p>
Choosing the right model for your home will depend on the climate you live. You'll need to look for the ENERGY Star or a performance chart that includes a SEER rating and HSPF rating. In warmer climates, you'll need to focus on SEER. in colder ones, look for HSPF.

</p>
<p>
Heating systems aren't just environmentally friendly, but they have many other benefits. They require less maintenance since they don't use fuel. Additionally, there is no risk of carbon monoxide leaks, fire or explosion. Heat pumps can also improve indoor air quality by increasing humidity in winter, and decreasing it in summer.
</p>
<p>
</p>
<p>
They don't create combustion byproducts and therefore do not add combustible gas to the air. This makes them an ideal choice for homes with vulnerable residents.
</p>
<p>
</p>
<p>
What are the disadvantages of the use of a heat pump?
</p>
<p>
</p>
<p>
Heat pumps are no different. They come with their own advantages and drawbacks. The most significant ones are their energy efficiency and environmental friendliness. The heat pumps unlike furnaces, which burn fossil fuels to generate heat, utilize renewable energy sources to transfer thermal energy from the air or into the ground and into your home. They are also more efficient than traditional heating systems and can save money on your electric bills.
</p>
<p>
</p>
<p>
The majority of heat pumps are more expensive to purchase than furnaces, but they will pay for themselves over time with lower operating costs. They are noisy, but new designs minimize this problem. They are most effective in homes with solid insulation and hermetic seals. They are most effective in climates that have moderate temperatures.
</p>
<p>
</p>
<p>
In the summer, they function as an air conditioning. By using a small amount of drive power, they take heat from the air inside your house and release it to the outside. In winter, they work in reverse taking the heat from outside and transferring it into the home.
</p>
<p>
</p>
<p>
This is made possible by the reversing valve that allows the refrigerant to move in either direction. The energy they use can come from a variety of sources, including geothermal energy stored in the ground, ambient temperatures in the air solar energy, or waste heat from industrial processes.
</p>
<p>
</p>
<p>
They are usually subject to a "time-of-use" pricing system due to the fact that they consume a substantial amount of electricity. This can raise their prices and make them less efficient as furnaces in colder climates.
</p>
<p>
</p>
<p>
Finally, the refrigerants used in heat pumps can leak into the environment and cause pollution. Although manufacturers are working on safer alternatives, they do have dangers and should only be used where it is necessary. However, in general there is a consensus that heat pumps are a more sustainable alternative to traditional heating methods and, with proper installation they can cut down your carbon footprint significantly. They are also an excellent option to get the taste of "green" living without making a major investment in a total heating air conditioning, ventilation and heating (HVAC) system.
