This is a huge advantage for homes that use large and frequent draws of hot water. So as electricity and gas costs continue to rise, these more efficient options attract many homeowners. Because of its combustion, gas produces heat more quickly than an electric heating element. For example, most hybrid heat pump units have a “vacation” mode that reduces operating costs when no one is at home. Condensing water heaters are more expensive than similar non-condensing units.
