A split system heat pump's defrost sensor is used to detect ice buildup on the heat pump's outdoor coil. When ice builds up on the coil, it reduces the heat pump's ability to transfer heat, which can ...

UK-based researchers have developed a novel method to estimate the amount of defrost cycles a heat pump will experience in the winter and how much energy it would require to implement the cycles. The ...

US startup TerraVis Energy is developing a residential heat pump that it claims can maintain high comfort levels without requiring defrosting. “The system is based on our soon-to-be patented ...

When winter rages and the temperature drops, your home’s HVAC system is more important than ever. There’s nothing worse than ...

Line chart that shows annual units of heat pumps and gas furnaces shipped, which is an approximation of sales, from 2002 through 2022. Heat pumps surpassed gas furnaces in annual sales in 2022 by a ...

Outside a 100-year-old house on the edge of the Peak District in northern England, a heat pump’s fan blades are swiftly spinning. They’re drawing outdoor air over coils of refrigerant, harvesting ...

For the last few years, much of the focus on cold climate heat pump (CCHP) technology has centered on air-source ducted systems, which are designed to deliver efficient, comfortable heating, even in ...

Heat pumps are emerging as an important tool for helping to thwart climate change—not just in the South, but all over the country. They’re more energy-efficient than traditional heating and cooling ...
