Tankless water heaters have gained popularity for good reason — they provide hot water on demand, take up less space, and can last 20+ years. But they're not the right fit for every home. Here's an honest look at what to expect.
How Tankless Water Heaters Work
Unlike traditional tank water heaters that store 40-50 gallons of preheated water, tankless units heat water as it flows through the unit. When you turn on a hot water faucet, cold water travels through a pipe into the unit where either a gas burner or electric element heats it instantly.
Benefits of Going Tankless
The primary advantages of tankless water heaters include continuous hot water (you'll never run out mid-shower), energy savings of 24-34% compared to traditional tanks, a compact wall-mounted design that frees up floor space, and a lifespan of 20+ years vs. 8-12 for tank units. Many homeowners also appreciate the reduced risk of water damage since there's no 40-gallon tank that can leak or rupture.
The Real Costs
A tankless water heater installation in the greater Los Angeles area typically costs between $3,000 and $5,500 installed, depending on the unit size and any gas line or venting modifications needed. That's roughly 2-3x the cost of a traditional tank install. However, lower monthly energy bills and a longer lifespan often make the math work out in favor of tankless over a 15-year period.
Things to Consider Before Switching
Tankless units have a maximum flow rate, usually 7-10 gallons per minute for gas models. If you're running multiple showers, the dishwasher, and the washing machine simultaneously, a single tankless unit may not keep up. Large households may need two units or a high-capacity model.
Gas tankless units also require proper venting and may need a larger gas line than your current setup. These modifications add to the installation cost but are a one-time expense.
