San Francisco Homeowners Face a Critical Decision: Electric vs Gas Water Heaters in the Era of Natural Gas Phase-Out

San Francisco residents are at a pivotal moment in their home’s energy future. With Bay Area regulators voting to phase out natural gas water heaters beginning in 2027, homeowners must navigate the transition from gas to electric water heating systems. This landmark decision affects the region’s 1.8 million homes and will fundamentally change how San Francisco families heat their water.

Understanding the Natural Gas Phase-Out Timeline

Under the ambitious timeline established by the Bay Area Air Quality Management District, only zero-emission, electric water heaters can be sold or installed in Bay Area homes starting in 2027, with the same rules applying to furnaces starting in 2029. The rules only apply to new water heaters and furnace purchases, and won’t require the immediate replacement of existing appliances. People can also still repair their broken-down gas appliances, but won’t be able to purchase new ones after the rules go into effect.

Gas appliances in residential and commercial buildings in the region account for a similar amount of harmful nitrogen oxide emissions as passenger vehicles. NOx emissions contribute to the formation of ozone and smog, and exposure has been linked to asthma and other respiratory conditions, along with increased risk of heart attack, stroke, lung cancer and premature death.

The Electric vs Gas Water Heater Comparison

Performance and Recovery Time

One of the most significant differences between electric and gas water heaters lies in their recovery rates. Gas water heaters heat water faster and supply a larger volume quickly, ideal for high-demand households, while electric water heaters are more efficient, converting nearly all energy consumed into heat, but heat water more slowly than gas models. Gas heaters excel in recovery rate, warming 30-45 gallons per hour, while electric models work more slowly, heating 14-20 gallons per hour.

Energy Efficiency and Operating Costs

Electric heaters are more efficient – an electric heater will use most of the energy it receives to warm water, making it more energy-efficient. Electric models lead in efficiency, converting 90-95% of energy into heat, while gas models typically achieve 60-70% efficiency, though high-efficiency units can reach 80%.

However, operating costs vary by region. The monthly energy bills tend to be lower with gas water heaters because natural gas rates typically run cheaper than electricity per BTU, making gas water heaters more economical to operate. Yet this advantage may diminish as San Francisco transitions to cleaner electricity sources.

Installation and Infrastructure Requirements

Electric water heaters typically cost less to buy than their gas counterparts. Likewise, a simple, straightforward installation that doesn’t require running lines or adding vents usually makes setting up an electric unit much less expensive. Converting from gas to electric, however, presents challenges. The increased cost of having an electrician run electrical from the electrical box to the site of the water heater is a whole new expense where they’re just changing out from a regular gas water heater to a regular gas water heater.

For older homes that may only have a 200-amp electrical panel, the change could require homeowners to upgrade their entire electrical system which would cost thousands.

Financial Incentives and Support

Fortunately, significant financial assistance is available to ease the transition. A new, zero-NOx electric heater will cost roughly $8,030, with an electrical panel upgrade adding another $2,630 to the total price tag. Meanwhile, a zero-NOx electric water heater costs about $2,820, plus roughly $960 for any needed panel upgrade.

Rebates for home energy-efficiency and electrification projects are currently available through the Inflation Reduction Act and will increase significantly in 2024. They include an $8,000 rebate for heat pumps that can warm and cool homes, $1,750 for heat pump water heaters and $4,000 for electrical system upgrades.

Safety and Environmental Considerations

Electric water heaters confer multiple benefits over gas units, including ease of installation, higher efficiency levels and safer operation. Electric water heaters, unlike gas water heaters, do not emit dangerous pollutants such as carbon monoxide.

Gas water heaters work during power outages – when that wind storm knocks out electricity for two days, you’ll still have hot water for showers and essential tasks, providing a reliability advantage that some homeowners value highly.

Making the Right Choice for Your Home

The decision between electric and gas water heaters in San Francisco’s changing landscape requires careful consideration of multiple factors: your home’s current infrastructure, hot water usage patterns, budget for upfront costs, and long-term operating expenses. Your household’s hot water demands should guide your final choice. Large families using hot water frequently might benefit from a gas heater’s faster recovery time. Smaller households or homes with more spread-out usage patterns might find electric models perfectly sufficient.

As San Francisco moves toward a cleaner energy future, the transition from gas to electric water heaters represents both a challenge and an opportunity. While the phase-out timeline may seem daunting, the combination of available incentives, improved electric water heater technology, and professional installation services makes this transition manageable for most homeowners.

The key is planning ahead rather than waiting for your current water heater to fail. By understanding your options now and working with qualified professionals, you can ensure a smooth transition that meets both your family’s needs and San Francisco’s environmental goals.
