How to Choose a Tankless Water Heater

Tankless water heaters have become very popular lately for good reasons. Tankless water heaters are more energy-efficient than traditional units because they provide hot water only when needed, rather than heating and reheating water in a standard storage tank, which can save money. Not only that but it takes up less physical space and does not have a significant storage tank.

Does this sound like the next investment for you? Consider a few things before buying a tankless water heater, such as the size of the unit, the energy efficiency and cost, the fuel type and availability, and any upgrades to gas lines or electric capacity that may need to be done.

How Do Tankless Water Heaters Work?

Tankless water heaters heat the water by running it through a series of burners, either a gas burner or an electric element, on the way to the tap. As a result, tankless water heaters produce a continuous supply of hot water without pause, compared to waiting for a storage tank to fill up with more hot water after a long, hot bath. A single tankless unit delivers a limited flow of hot water per minute, so to overcome this limitation, you may want to consider more than one tankless unit in your home.

Choosing One for You

Size is very important when choosing a tankless water heater, because having one that is too small will result in a lack of hot water for your household demand, and you may be unable to run more than one shower at a time for example. However, a tank that is too large for your household will end up being more costly than necessary. Having a water heater that is just the right size is important. There are two factors that need to be considered when sizing a tankless water heater: flow rate and temperature rise.

The flow rate is measured in gallons per minute and can determine the total rate at which the water heater will need to produce hot water by adding the flow rates for each fixture together. Next, calculating the temperature difference between the water entering the heater and the temperature desired at the faucets is called the temperature rise.

These two factors are used to calculate the tank size required for your home and ensure that you get the right unit.
