Heat from the range is absorbed, causing the water molecules to move more quickly and become a gas. This is what happens when you boil water. During this process, it will absorb heat from its surroundings. Phase changes occur when a substance moves from a liquid to a gas (evaporates). As they do, heat naturally flows from the air to the coil of refrigerant. When heating, heat pumps take advantage of entropy by making the outdoor unit colder than the ambient air temperature. Heat is always trying to move from a hotter place to a cooler place (aka entropy or the second law of thermodynamics!).
The temperature in a substance is just a measure of the average kinetic energy of the particles. To understand that, we need two basic concepts from high school physics: heat and phase changes. While the high-level operation can make sense, it's a little hard to wrap your head around the idea of heat pumps without scratching a layer below the surface. All the components are working together to move heat inside the house. Want to figure out what a heat pump could mean for your home? Read on. We wanted to create a tool that is simple enough for a typical homeowner to understand, but detailed enough for an HVAC technician to believe. We couldn't find one, so we built this guide. We looked long and hard for a way to understand the impact of getting a heat pump. With one decision, the median homeowner will save 30 tons of CO 2 emissions over the next 15 years - thats equal to twice their entire annual footprint. Switching to a heat pump is one of the few individual actions you can take to drastically reduce your climate impact. If all homes switched to heat pumps, US homeowners would save $24 billion dollars per year on utility bills and reduce annual emissions by 152 million tons of CO 2.
They are more comfortable, cheaper, and more environmentally friendly than a traditional furnace and AC combo.Īccording to our analysis, 93% of single family homes in the US would save money with a heat pump compared to their existing equipment. Heat pumps are a high-efficiency, low-emissions option for heating and cooling homes. These nondescript devices are called heat pumps. Behold: the space-age, 400% efficient technology known as a 'Heat Pump'
