How to Choose Your New Water Heater: Gas vs. Electric

When purchasing a new water heater, the first decision you will need to make is the type of fuel source you prefer to heat your water. The main options are gas and electric. The availability of fuel, price, efficiency, and personal preferences should be considered when selecting the best model. There are advantages to each type of system.

FAQs

Should I replace my water heater or schedule a repair?
Deciding between repair and replacement depends on the age of your water heater, the type of failure, and the cost of the repair. In Arlington and other inner-Beltway communities, many homes still have older water heaters that are near the end of their lifespan. If your unit is 8–12 years old and needs a major repair, replacement is often the more reliable and cost-effective long-term option.

What are the most common water heater problems homeowners experience?
One of the most common problems is not having enough hot water to meet household demand. In many post-war and mid-century Arlington homes, we frequently find undersized 30–40 gallon tanks that can’t keep up with modern usage. Sediment buildup from Northern Virginia’s moderately hard water can also reduce efficiency, cause noise, and shorten the lifespan of the unit.

Are gas or electric water heaters more affordable to run in Northern Virginia?
Operating costs depend on local utility rates, but in Northern Virginia, gas water heaters are often less expensive to run than traditional electric tank models. Many Arlington neighborhoods use a mix of gas and electric water heaters depending on when the home was built and how local infrastructure was developed. We help homeowners compare total ownership costs based on fuel type, usage needs, and installation requirements.

How long does a new water heater installation usually take?
Most standard water heater installations can be completed in a few hours. Replacing an existing tank with a similar model is usually straightforward, while tankless installations or fuel-type conversions may take longer if venting, gas lines, or electrical upgrades are needed. Older Arlington homes often require these updates to meet current code.

How do I know what size water heater my home needs?
Water heater sizing depends on household size, usage patterns, and the number of bathrooms and appliances in your home. Many Arlington homes were originally built with smaller plumbing systems and lower hot water demand in mind. Our technicians calculate the correct tank size or tankless capacity based on real daily usage to prevent running out of hot water.

What is the difference between a tank and a tankless water heater?
Tank water heaters store a set amount of hot water and are typically less expensive to install. Tankless water heaters heat water on demand and provide continuous hot water. In Arlington condos and townhomes, especially in areas like Clarendon and Ballston, compact tank models or tankless systems are often the best space-saving option.
