Hearth Industry Statistics

U.S. households are leaning more into electrification, with 38% using electricity for space heating and 31% already owning a heat pump in 2023. The same households still pay a price for old habits and equipment choices, from only 12% using wood stoves or fireplaces for heat to central air costs that can run $5,000 to $10,000, making this page essential for anyone tracking where hearth and heating upgrades are heading.

In 2023, 2,530,000 US households powered their homes with solar as a primary electricity source, while 31% still rely on natural gas connections for day to day energy needs. At the same time, the Inflation Reduction Act backed up upgrades with $9 billion in Home Energy Rebates, pushing heat pump and thermostat adoption alongside familiar heating choices. Here’s how these hearth focused realities line up across heating, cooling, and fuel prices, and what they suggest about where home comfort spending is headed next.
