What is a tankless water heater?

The primary feature of a tankless water heater is that it is as the name suggests, tankless; therefore, hot water is only provided on demand or as needed. The associated benefit with this particular feature is the reduced energy costs as there is no need to constantly heat a storage tank of water.

How does a tankless water heater work?

When a hot water tap is turned on, cold water travels through the pipe into the tankless water heater unit. If it is an electric tankless water heater, the electrical elements will heat the water. If it’s a gas tankless water heater, the gas burner heats the water; both variations resulting in a constant supply of hot water.

What do I need to consider when choosing a tankless water heater?

How many people live in the home?

What will the hot water be used for?

How do I determine the energy efficiency rating? The new industry standard for measuring energy efficiency in water heaters is now called Uniform Energy Factor (UEF). This new standard recently came into effect on June 12, 2017. The new UEF standards are designed to make it easier for consumers to compare energy efficiency between appliances.

What are the benefits of a tankless water heater?

As previously mentioned, the biggest advantage to a tankless water heater is the reduced energy costs as there is no requirement to heat a water tank. Additionally, you don’t have to wait for a storage tank to fill up with water. With a tankless water heater, you get hot water on demand.

Maintenance and replacing parts can extend the life of your tankless water heater and the working age of a tankless water heater would likely exceed a traditional hot water tank.

Tankless water heaters are very convenient and take up very little room, especially in comparison to a traditional hot water system. Tankless water heaters are designed to be wall mounted, reducing space in your home.

Are there any disadvantages to a tankless water heater?

As with all products, there are advantages and disadvantages both of which we will discuss here. Generally, a tankless water heater will provide a hot water flow rate between 2-5 gallons per minute. In a large household where multiple activities that require hot water may be occurring at the same time; if for instance, someone is taking a shower and the dishwasher is running simultaneously, a tankless water heater may be exceeding its capacity to supply hot water to both activities. To alleviate this problem, a simple fix is to install two tankless water heaters to meet the hot water demands of a large household.

When comparing costs between a traditional hot water tank and a tankless water heater, the cost of the latter can often be greater. However the excess outlay for the tankless water heater will be regained through energy cost savings and a longer lifespan. A traditional hot water tank lifespan is approximately 10-15 years; a tankless water heater is more likely to last longer, up to 20 years if looked after accordingly.

Electric vs Gas…what’s better?

Unfortunately, there is not an answer to this question; both variations have pros and cons and you will need to decide what works best for you. You may not even have an option to decide between the two as availability may be a problem. Let’s look at this further.

Product Cost: A primary factor in making a purchasing decision will be the cost and value for money for a particular product. Electric tankless water heaters will set you back anywhere from as little as $100USD up to $700USD for the device (professional installation will be additional to this). A gas tankless water heater is very similar in price. The cheapest propane-powered model is approximately $120USD and can range up to $2000USD, therefore, when considering whether gas or electric is a better model, initial product cost does not vary significantly enough to make a decision based on this particular factor.

Fuel Costs: In the United States, current gas prices are lower than electricity so this may be a factor worth considering when deciding on the type of tankless water heater model you would like to go with. If you are fortunate enough to have the option of choosing electricity or gas, it’s worth comparing fuel costs in your particular area to

Environmental Impact:

Installation requirements and costs: Electric tankless water heaters are slightly easier to install. Tankless water heater venting is not a requirement as it is with gas models.
