So, you\u2019ve heard that heat pumps are efficient and very cost-effective. Maybe you\u2019re considering an installation<\/a> for your home, but maybe you\u2019re also not quite<\/em> convinced. Can a heat pump really heat your home properly when nights can hit below freezing on a regular basis? Find the answer to one of our most common heat pump questions by following along!<\/p>\n

A Quick & Simplistic Rundown of How a Heat Pump Works<\/h2>\n

We\u2019ve dedicated posts to this topic<\/a> in the past, but in case you\u2019re new it will help you understand how well a heat pump can handle your heating needs if you know how they work<\/em>. At its simplest, a heat pump does essentially what it says in the name. It pumps heat.<\/p>\n

The system is designed to pull heat from its source<\/em> (air-source for standard heat pumps, ground-source for geothermal systems<\/a>), meaning during the summer a heat pump will draw heat out of your home, and during the winter it draws heat in<\/em> from the outdoors. This is much of the reason why heat pumps are so efficient and cost-effective to operate\u2014because they harness energy that\u2019s already present, which lessens the amount the system needs to expend to do its job.<\/p>\n

But There\u2019s No Heat Outside! It\u2019s Winter<\/em>!<\/h2>\n

Well, you\u2019re right about the second part. It is most certainly winter. However, there is actually always<\/strong> some amount of thermal energy present in the air. That means that even when it\u2019s 20 degrees outdoors, there\u2019s still<\/em> plenty of heat for a pump to draw on.<\/p>\n

Additionally, even if a heat pump finds itself incapable of keeping up on its own, which is an honest possibility, then its backup systems will kick in. All modern heat pump systems are fitted with electrical systems that are essentially identical to an electric furnace (or in some cases a gas furnace). If it\u2019s cold enough outside to impact the performance of the heat pump, the electric or gas components kick in to help the pump with some of the heavy lifting.<\/p>\n

So in short, yes a heat pump can keep your home warm in the winter. <\/strong><\/p>\n

But This Will Impact the System\u2019s Efficiency<\/h3>\n

It\u2019s worth noting that while the system can keep up no matter what, the use of a heat pump auxiliary heating source will lower efficiency and will increase your energy costs a bit. Even in this case, the heat pump is still notably more efficient than standalone furnace systems. The heat pump will continue to draw on ambient outdoor heat, which will lessen its fuel\/energy needs, thus saving you money even on the worst Pennsylvania or New Jersey winters.<\/p>\n

To guarantee your heat pump is operating at peak efficiency, you must ensure:<\/p>\n
