Should You Get a Tank or Tankless Water Heater?
A tank water heater costs $1,200-$2,500 installed and lasts 8-12 years. A tankless water heater costs $2,500-$5,000 installed but lasts 15-20 years and uses 24-34% less energy. Tankless gives you unlimited hot water; tank is simpler to install. The right choice depends on your home's plumbing, your family's usage, and your budget. Already seeing signs your water heater is failing? Don't wait. Here's a side-by-side comparison.
Tank Water Heaters: The Familiar Choice
Tank heaters store 40–75 gallons of hot water, ready when you need it. They cost $1,200–$2,500 installed, last 8–12 years, and work with standard gas or electric connections. The downside: they keep heating water even when you're not using it (that costs money), and once the tank is empty, you wait 30–60 minutes for more hot water.
Tankless: On-Demand Hot Water
Tankless heaters only heat water when you turn on a faucet - no tank, no wasted energy keeping water hot all day. They cost $2,500–$5,000 installed but last 15–20 years and use 24–34% less energy than tanks. You get unlimited hot water - but if you run the shower, dishwasher, and washing machine at the same time, smaller units can struggle to keep up.
What Happens If You Pick the Wrong Water Heater?
Tankless sounds great - but it's not perfect for every home. Older homes may need gas line or electrical panel upgrades that add $500-$1,500 to the install. Big families with heavy simultaneous use may need two units. On the other hand, sticking with a tank when you'd benefit from tankless means overpaying on energy bills for the next decade. Central Illinois hard water also affects both types differently - tankless units need descaling, and tank units accumulate sediment faster. The wrong choice costs you money either way.
