Instantaneous Water Heaters – Why Go Tankless?

Homeowners Life Smart

Tankless water heaters, which also go by the name instantaneous or demand-type water heaters, offer hot water only when it’s needed. Their best attribute is the fact that they never produce standby energy losses related to storage water heaters saving you a substantial amount of money. Tankless water heaters revolutionize convenience, energy efficiency, and comfort.

How They Work

Tankless water heaters directly heat water without using a storage tank. Cold water travels via a pipe right into the unit whenever you turn on your hot water. Either an electric element or a gas burner heats the water. Consequently, tankless water heaters normally deliver a non-stop hot water supply. There is no need of waiting for enough water to fill your storage tank.

Nonetheless, the output of these tanks can reduce their flow rate. But that isn’t always a problem if you select the proper sized unit for your household needs. Typically, instantaneous water heaters offer hot water at 7.6-15.2 litres per minute. Compared to electric tankless water heaters, gas-fired tankless water heaters tend to produce higher flow rates.

Other applications that can benefit immensely from demand-type water heaters include:

  • Remote hot tubs or bathrooms
  • Booster for solar water heating systems
  • Booster for appliances such as washers or dishwashers

Choosing a Tankless Water Heater

Among the various models and brands of tankless water heaters in the market, how do you settle for the best? Before purchasing one, you should consider these factors:

  1. Cost
  2. Size
  3. Energy factor (Energy efficiency) – The higher the energy factor the more efficient your water heater will be.
  4. Availability
  5. Fuel type

Why Install an Instantaneous Hot Water Heater

Efficient tankless water heaters help you save money in comparison to the storage tank types. Saving energy not only reduces your carbon footprint, it also saves you money substantially.

Most tankless hot water units are small and compact and mount to the wall. This allows you to free floor space to be used for other purposes. It also allows you to located the units closer to the areas where most of your hot water is used, further reducing the energy costs related to water sitting in lengthy runs of water pipe between your old hot water tank and the faucets that it serves.
