Hot Water Tanks vs Tankless Water Heaters


In this article we are going to discuss the benefits and drawbacks of both tank-style hot water heaters and tankless water heaters. Chances are that you have a traditional hot water tank inside your home. Hot water tanks have been used for decades and are inexpensive and reliable. In the last few years, tankless water heaters have becoming increasingly popular due to their efficient performance and compact size. It can be hard to determine which type of water heater is ideal for your needs. If you have questions, we would be happy to assist. Learn more about our hot water heater installation services.

Hot Water Tanks

This is what most people think of when they talk about hot water heaters. Hot water tanks store heated water at a preset temperature inside their storage tanks.

Advantages

  • Affordable – Hot water tanks are widely available and are very affordable
  • Reliable – The technology used inside hot water tanks is tried and tested. A new hot water tank that is professionally installed should give you at least 10 years of trouble-free hot water.
  • Easy to service – Most hot water tanks are relatively easy to service. In the event of a breakdown, the cost of repair is likely less expensive compared to its tankless counterpart.

Disadvantages

  • Heated water must be stored – The biggest drawback with a tank-style water is that it has to maintain its stored water at a certain temperature. This uses energy round the clock, even when you aren’t using hot water.
  • Requires more space – Compared to a tankless water heater, a hot water tank requires four or fives times as much space. It must be installed on the floor, with enough space surrounding it to ensure safe access to all mechanical components.
  • Finite capacity of hot water – Since hot water is actually provided on-demand from the storage tank, once the stored supply of hot water is exhausted, no more hot water is available until the water heater has heated and stored more water.This means that you may run out of hot water during periods of heavy use. If you have a large family, chances are pretty good that you’ve run out of hot water during the morning shower-rush more than once.

Tankless Hot Water Heaters

Tankless water heaters are becoming increasingly popular, especially in homes where there is limited utility or storage space.

Advantages

  • “On demand” supply of hot water – As a tankless water heater does not store hot water, it heats the water to the specified temperature on-demand.
  • “Limitless” supply of hot water – While not actually limitless, a tankless water heater can provide a seemingly inexhaustible supply of hot water. This makes a tankless water heater an excellent solution for large families or applications where large quantities of hot water are required.
  • Lower utility costs – In homes that use more than 41 gallons of hot water per week, a tankless water heater may reduce hot water costs by as much as 35%.
  • Compact – A tankless water heater is much smaller than their tank-style counterparts. They can be mounted discreetly on a wall, leaving valuable floor space open for utility use or storage.

Disadvantages

  • More expensive than hot water tanks – Despite their growing popularity, a tankless water heater is still considerably more expensive than a hot water tank.
  • Higher installation cost – Compared to a hot water tank, installing a tankless water heater is more complex and thus is more expensive. This is especially true when retrofitting a tankless water heater into a home that used to have a hot water tank.
