Are electric furnaces and water heaters inherently healthier?
Electric furnaces operate somewhat like a toaster. They contain a heating element that warms the air. Electric boilers and water heaters also contain heating elements. Electricity is convenient to use—but it can be an expensive way to heat a house, or to heat water. Heat pumps use electricity more efficiently, so they’re often more cost-effective. Plus, they can provide both heat in the winter and air conditioning in the summer. Some heat pumps have an outdoor unit that pulls heat from the air. Geothermal heat pumps pull heat from the earth. Heat-pump water heaters are also available. Electric appliances are sort of a mixed blessing. Their biggest health advantage is there are no combustion by-products. But it should be remembered, combustion by-products aren’t a problem with sealed-combustion appliances either. Although in most cases fuel leaks aren’t as serious a problem as combustion by-products, electric appliances will never leak any fuel. But, they can be surrounded by electromag
