Tank Water Heater
You’re probably familiar with the most common water heater: tank water heaters. Ranging from 20 to 100 gallons tanks, these heat water in your home at all times. When hot water is required—at sink or shower for examples—the water circulates to the open faucet. Conventional tanks utilize electric, natural gas, propane, oil, solar, or geothermal power as an energy source to heat the water.
