How do tank water heaters work?

The process begins with cold water flowing through a "dip tube" into the tank. Multiple temperature sensors continually measure the average temperature of the water in the tank. The heating mechanism is triggered if the temperature drops too far below the set point. The mechanism then turns off when the water's temperature reaches the desired set point. In natural gas or liquid propane water heaters, a flame under the tank and a hot air flue running up through the center of the tank heats your water. In standard electric water heaters, resistive wire heating elements are immersed in the tank to heat the water. Yet another way to heat your water comes in a hybrid electric heat pump water heater. This style uses electricity to efficiently transfer heat from the ambient air into the water through a compressor and a condenser. Hot water exits the tank through a hot water outlet and is distributed wherever it's needed.

Both State tank and tankless water heaters provide solutions for dependably delivering hot water to your home.

Tank water heaters are more affordable when it comes to price, installation and repair costs. They are easy to install and more likely to work with existing systems. With a tank water heater, you'll have a solid supply of hot water - even if the power goes out.

Tankless water heaters have a much smaller footprint, leading to saving lots of space. They can fit easily in bathrooms, under sinks or in closets. Tankless water heaters offer on-demand access to continuous hot water, and they'll help you save costs and energy because of their high-efficiency operation.

State is committed to making resilient, durable water heaters. All State tank water heaters have a limited warranty lasting several years, and it's common for State tank water heaters to keep working hard to deliver hot water for even longer. State tank water heaters are built to last when properly installed and maintained over time in areas with good water quality.

Tank water heaters should be flushed annually to clear out sediment and mineral deposits that can accumulate over time. This simple practice keeps your water heater operating efficiently and dependably for years to come.

Signs it's time to replace your tank water heater include:
Water is leaking from your tank
Rust-colored tap water
Sediment in your water
Noises: banging, rumbling, cracking or popping
Lukewarm water that won't heat above 120 degrees Fahrenheit
