Gas vs. Electric Water Heaters — Which Is Right for You?



Choosing between gas and electric depends on several factors, including your existing utility connections, energy costs, and usage demands. Here is a quick overview:

Gas Water Heaters

Gas water heaters typically heat water faster and tend to cost less to operate in areas where natural gas is available. They are a popular choice throughout St. Louis and the metro area for both residential and commercial applications.

Electric Water Heaters

Electric water heaters are a reliable option for homes or businesses without a natural gas connection. Modern electric units are highly efficient and require less complex venting compared to gas systems.

Frequently Asked Questions About Our Water Heater Services



  • How long does a water heater typically last?

    Most traditional tank water heaters have a lifespan of 8 to 12 years with regular maintenance. If your water heater is approaching or past that range and showing signs of problems such as rust, leaking, or inconsistent hot water, replacement is usually more cost-effective than continued repairs. Arch City Drain and Plumbing can assess your unit and help you decide whether repair or replacement is the smarter investment.

  • What is causing my water heater to produce rusty or discolored water?

    Rusty or discolored water from your hot taps is most commonly caused by corrosion inside the water heater tank. This often indicates that the sacrificial anode rod has been depleted and needs replacement. In older units, it may signal that the tank itself is beginning to corrode and will soon fail. Contact Arch City Drain and Plumbing to have your unit inspected.

  • Do you install both gas and electric water heaters in St. Louis?

    Yes. Arch City Drain and Plumbing installs and repairs both gas and electric water heaters for residential and commercial customers throughout St. Louis, MO, St. Charles, O'Fallon, Wentzville, and the surrounding areas. We can also advise you on the most efficient option for your property based on your existing utilities and usage demands.

  • What size water heater do I need for my home?

    The right water heater size depends on the number of people in your household and your peak hot water demand. As a general guideline, a 30 to 40-gallon tank suits 1 to 2 people, a 40 to 50-gallon tank works well for 3 to 4 people, and larger households typically need a 50 to 80-gallon unit. Our licensed plumbers can evaluate your needs and recommend the right size and model.

  • How much does water heater installation cost in St. Louis?

    The cost of water heater installation in St. Louis depends on the type of unit, the tank capacity, the complexity of the installation, and whether any existing connections need to be modified. Arch City Drain and Plumbing provides free, upfront estimates with no hidden fees so you know the full cost before any work begins. Call (314) 400-0303 to get your free estimate.
