Gas vs. Electric Water Heater: Which Is Right for Your Maryland Home?
July 5, 2026 · 6 min read · By Deep Dive Plumbing Maryland
When your water heater fails, you have a decision to make — and it is worth making it thoughtfully rather than just replacing like-for-like. Gas and electric water heaters have different operating efficiency, lifespans, and installation requirements. Here is what Maryland homeowners need to know.

| Feature | Gas | Electric |
|---|---|---|
| Upfront cost | Contact us for a free estimate | Contact us for a free estimate |
| Operating cost | Lower — gas is cheaper than electricity per BTU | Higher — electricity costs more per BTU |
| Recovery rate | Faster — heats water more quickly | Slower — takes longer to reheat after use |
| Lifespan | 8–12 years | 10–15 years |
| Installation | Requires gas line and venting | Simpler — just electrical connection |
| Works during power outage | Yes (pilot light models) | No |
| Energy efficiency | Good (0.60–0.70 EF) | Excellent (0.90–0.95 EF) — but higher cost fuel |
Frequently Asked Questions
Is gas or electric cheaper to operate in Maryland?
Gas water heaters are typically less expensive to operate in Maryland. Even though gas heaters are less energy-efficient than electric (they lose some heat through the flue), natural gas costs significantly less per BTU than electricity in Maryland. However, if you do not already have a gas line, running one is a separate project that takes time and planning.
Which type lasts longer?
Electric water heaters typically last 10–15 years versus 8–12 years for gas. Electric heaters have fewer components (no burner, no flue, no thermocouple) and are less prone to combustion-related failures. However, in hard water areas like Calvert and Anne Arundel County, sediment buildup affects both types equally — regular flushing is the biggest factor in longevity for either type.
Can I switch from electric to gas?
Yes, but it requires running a gas line to the water heater location and installing proper venting. In a home without existing gas service, this is a more involved project depending on the distance from the gas meter. If your home already has gas service (for a furnace or range), adding a gas water heater is more straightforward. Deep Dive Plumbing Maryland handles gas line work and water heater conversions.
What about heat pump water heaters?
Heat pump water heaters (hybrid electric) are the most efficient option — they use 60–70% less electricity than standard electric heaters by pulling heat from the surrounding air. They work best in unconditioned spaces (basements, garages) with ambient temperatures above 40°F. They qualify for federal tax credits and deliver strong long-term energy savings.
