Why heat pumps are a cost-effective and climate-friendly solution for extreme heat waves and frigid winters.
to expedite US manufacturing of heat pumps and other clean energy technologies to bolster energy security, counter climate change, and create jobs. In this article, we’ll break down some of the most common types of heat pumps, how the technology works, and how heat pumps can save people money on heating and cooling, all while cutting planet-warming greenhouse gas emissions and leading the way to healthier indoor and outdoor air quality.
In heating mode, the flow of refrigerant reverses. The refrigerant absorbs heat from the outdoors and vaporizes inside the sealed system. Crucially, the refrigerants used in heat pumps have very low boiling points and can efficiently absorb heat even from cold winter air. That heat can then be moved to the indoor environment by compressing the vapor and passing it through an interior coil, where it releases some of its heat.
Because a heat pump merely moves heat rather than generating heat, it can produce over four times as much heat energy as it consumes in electricity, resulting in lower energy use and operating costs than electric resistance heaters. As shown below, heat pumps also greatly outperform gas furnaces. Importantly, heat pumps help home and building owners avoid the burning of gas indoors, removing any potential risks of carbon monoxide poisoning or dangerous gas leaks and explosions.
