Heat pumps use less energy than other heating systems and therefor reduce the creation of greenhouse gases. This heat pump guide explains how heat pumps make the world greener. It also provides tips for choosing the most energy-efficient heat pump for your home.
How Heat Pumps Produce Green Heating
The heat pumps being manufactured today by all the leading brands are much more efficient than those produced just 10-20 years ago.Fifteen years ago the average SEER rating, an efficiency rating, for heat pumps was 9. Today the average is about 17. Some models offer SEER ratings over 20 and many homeowners are installing heat pumps that are twice as efficient as the ones they replace. That means they produce about half the greenhouse gases. That’s a huge difference for the environment. Energy Star heat pumps have 14.5 SEER ratings and higher.
Heat pumps are more energy-efficient than gas furnaces, resulting in fewer carbon emissions. In other words, the emissions produced making the electricity to run a heat pump are less than the emissions produced by a gas furnace.
Heat Pumps Use Safer Refrigerant
Refrigerants containing chlorine deplete the earth’s ozone layer and are linked to global warming. Those refrigerants are being rapidly phased out. Most manufacturers are using only new chlorine-free refrigerants. The most common is R-410A which is used under that name or under brands names such as Puron and Smart Cool 410. Check heat pump review sites to find models that use R-410A. You can also find information on efficiency, features and pricing.
R-410A is also more efficient. It does a better job absorbing heat during a heating cycle and shedding that heat inside the home in order to warm the air. Heat pump and refrigerant technology is on the cutting edge of new, greener methods to heat and cool our homes.
Choosing a Green Heat Pump for your Home
Read heat pump reviews and articles on these sites to learn more about heat pumps. Use the reviews to find which heat pumps are most efficient. As noted, heat pumps of 14.5 SEER or higher are Energy Star products but most current heat pumps exceed that. You’ll find models with SEER ratings over 20.
All heat pumps that achieve Energy Star qualification use R-410A refrigerant, so that’s covered. The next step for you is to choose the most efficient heat pump you can afford. Even 16 SEER to 18 SEER heat pumps will dramatically reduce greenhouse gases when replacing a model 12-25 years old. They will also use less energy and reduce carbon emissions compared to a 90% efficient Energy Star gas furnace.
If you are committed to a greener lifestyle, choosing an energy-efficient heat pump is a very good place to start. In moderate and warm climates, look at standard heat pumps. In climates where winter weather drops below freezing, a dual fuel heat pump is a better choice. Again, research heat pump reviews and articles to find models that would be best for your home.
