Type of Water Heaters and How They Work

Water heaters are a costly but needed investment for your home. So, when it is time to put in a new water heater, it is important to consider efficiency, cost, and longevity of the new water heater. There are two main types of water heaters available in the market – Tankless or On Demand and Tank Storage water heaters.

Tankless Water Heater

Tankless water heaters use high powered burners to rapidly heat water and deliver it directly to your faucets and showers. It doesn’t store hot water in a tank and hence is known as on-demand. They are usually powered by gas or electricity. As per consumer reports, these were found to be 22 percent more energy efficient than other water heaters.

Pros –Tankless Water Heater

  • Saves more money over time and is more energy efficient.
  • Longer useful life, lasting 20 to 30 years. Areas with “Hard Water” may reduce the life of the heater.
  • Consumes less space as there is no storage tank. It can be installed in tight quarters as they are small or even be installed outside the house.
  • You can get hot water when you need it as it takes the heater one minute to deliver two to three gallons of hot water.

Cons – Tankless Water Heater

  • The cost of purchase is higher and so is the installation if you are replacing a storage tank heater with a tank less heater.
  • Multiple showers or doing laundry simultaneously with showering can make the tankless heater fail in keeping up with the hot water demand.

Tank Storage Water Heaters

Storage tank water heaters are the most common heaters found in homes. It consists of an insulated tank to hold 30-50 gallons of water to heat and store for use. A pipe is attached to the top to deliver water to bathrooms or kitchens. They typically run on natural gas or electricity. The heaters running on natural gas use 50 percent less energy and cost lesser to operate than the electric versions. But they cost a little more than the electric models. They also have a temperature and pressure-release valve that opens when the pressure-temperature exceeds preset levels.

Pros –Storage Tank Water Heater

  • The initial cost is lower, with less costly maintenance and repairs.
  • Their operation is simple and hence much easier to repair than a complex tankless heater.

Cons – Storage Tank Water Heater

  • Higher utility bills and they occupy a lot more space. They cannot be placed outside the home.
  • As the water in the tank heats at one time and then used over time, the last person to take a hot shower may get a cold one.
  • They have a shorter useful life and will need to be replaced.
