Tank-Type Water Heaters: The Best Type Of Water Storage System

A tank-type water heater is a simple device and a common type of residential water heater. The storage tank water heater comes in different sizes, from 20-80 gallons and is fueled by different sources:

  • Oil
  • Electricity
  • Natural gas
  • Propane

The storage tank-type water heater raises and maintains the water temperature to the setting on the tank. The water is kept ready and constantly heated for use in the tank, the heat energy can be lost even if no faucet is on called standby heat loss.

How does the storage tank water heater work?

A storage tank water heater or conventional water heater provides a steady hot water supply for residential and commercial purposes. It works by heating and storing a specific volume of water in an insulated tank until needed. A storage tank water heater works through the following sequence:

  • Water inlet. The cold water passes through the tank through a pipe connected to the tank’s bottom.
  • Heating element. There are 1 or 2 heating elements inside the tank. The heating elements are accountable for increasing the water temperature in the tank.
    • Electric water heaters
    • Gas water heaters
  • Thermostat control. The thermostat is a temperature-sensing device maintaining the desired water temperature in the tank.
  • Insulation. The tank is well-insulated to prevent heat loss. This insulation helps keep the water hot, reducing the need for the heating element or burner to cycle on frequently.
  • Hot water outlet. When you open a hot water tap, the hot water passes from the top of the tank through a hot water outlet pipe. The action triggers the cold water inlet to bring in fresh cold water to replace the used hot water, ensuring a continuous hot water supply.
  • Pressure relief valve. For safety reasons, storage tank water heaters have a pressure relief valve that opens to release excess pressure or temperature within the tank, preventing potential damage or hazards.
  • Drain valve. The drain valve of the tank’s bottom permits you to drain and flush the tank occasionally to clear sediment and minerals that gets over time. It helps maintain the heater’s efficiency and prolong its lifespan.
  • Tank size. The storage tank’s size changes depending on the household’s hot water needs. The tank size determines the volume of hot water that can be stored and supplied at any given time.

Storage tank water heaters are reliable and cost-effective. Newer tankless water heaters are more energy-efficient and provide hot water on demand without a storage tank.
