Any home can stay warm through the roughest winter thanks to the power of modern heating systems. But heating a home can also make it feel stuffy. This is often a complaint people have about gas furnaces, but it can happen with boilers and heat pumps as well. The obvious solution is to open up some windows—but that lets in blasts of cold air, leading to discomfort and making the heating system work extra hard trying to overcome it.
However, we propose another solution. One that allows you to vent out the stale and stuffy air in your house and replace it with fresh air from outside, but without having to open up the house to cold drafts and driving up your energy bills. And that solution is an ERV.
