Electric vs. Gas Water Heaters: What to Choose?

Electric vs. Gas Water Heaters
June 27, 2025

Hot showers, clean dishes, warm laundry — we tend to take hot water for granted until something goes wrong. And when it’s time to replace or install a water heater in your Southampton or Suffolk County home, one of the greatest decisions you’ll make is:

Electric or gas?

Here at Paradise Plumbing, we assist homeowners throughout Southampton, Easthampton, Shirley, Quogue, and the wider area in making informed, energy-saving decisions for their homes. In this post, we’re going to break down the advantages and disadvantages of electric vs. gas water heaters for you — no tricky terminology, just straight-shooting local advice.

First Things First: How Do They Work?

Gas water heaters burn natural gas or propane to warm water. The water is heated by a burner located at the bottom of the tank and is stored.

Electric water heaters use electric heating elements within the tank.

Both are available as traditional tank-style units or tankless models. The principal difference is how they are powered and that affects cost, installation, and performance.

Operating Costs & Energy Efficiency

Gas Water Heaters

Gas heaters tend to heat water more quickly and are cheaper to run if natural gas is accessible in your location. Gas tends to be less expensive than electricity in most of Suffolk County, so bills are less per month.

But there’s the rub. Gas heaters are less energy-efficient overall, as some of the heat goes out via the venting system.

Electric Water Heaters

Electric models tend to be more energy-efficient since they don’t lose heat by way of flue gases. If you’re committed to green energy or minimizing carbon emissions by your home, electric may be the direction to go particularly if you eventually install solar panels.

Paradise Tip: We assist you in comparing your current utility costs and energy consumption to see which option saves you money in the long term.

Installation and Initial Investment

Gas Heaters:

  • More expensive installation if gas lines or venting aren’t already available
  • Can necessitate building permits and inspections
  • Ideal for homes that are already outfitted with natural gas

Electric Heaters:

  • Less difficult and less expensive to install
  • No gas lines or complicated venting required
  • Perfect for homes that don’t have existing gas services

So, if you’re upgrading a gas heater in an existing home that already has gas infrastructure, it’s logical to remain with gas. But for new construction or rehabs, electricity could be easier and less expensive in the short term.

Heating Speed and Recovery Rate

Gas takes the win here.

Gas water heaters also heat water more quickly than electric ones. If you have a big family in which everyone is showering one right after another or if you’re operating several hot-water devices at the same time, a gas heater will probably keep pace better.

Electric models simply recover slowly, so if hot water usage is extreme, you’ll deplete your water faster.

Paradise Plumbing Pro Tip: We tend to suggest gas units for larger households, and electric ones for smaller families or second homes such as beach houses in Southampton.

Longevity and Maintenance

Both require periodic maintenance, such as draining the tank or inspecting the anode rod, but gas heaters also have some additional maintenance steps:

  • Inspect the light and burner
  • Provide adequate ventilation

Electric water heaters have fewer working components, so they typically need less long-term upkeep.

Safety and Environmental Impact

Gas heaters do carry risks of carbon monoxide leakage or exposure to gas. The risk is higher if the unit is old or inadequately vented.

Electric water heaters are safer because they don’t have leaks of gas. They’re also quieter with no open flame.

Which One To Choose?

Well, Look for yourself!

Factor Gas Water Heater Electric Water Heater
Monthly Cost Lower (if gas is available) Slightly Higher
Upfront Installation Higher Lower
Heating Speed Fast Recovery Slower Recovery
Energy Efficiency Slightly lower Higher
Maintenance Moderate Low
Safety Requires checks Safer, no combustion
