Ultra-efficient electric heat pump water heaters are a better alternative to gas water heaters. They’re healthier, safer and help fight climate change. Gas appliances emit carbon monoxide and other pollutants, which can be harmful to your health. And burning gas for heat and hot water is one of the biggest sources of greenhouse gas emissions in California. SMUD customers are eligible for rebates when replacing a gas water heater with a more efficient heat pump water heater. Learn more at smud.org/rebates.
