Commonly referred to as an on-demand water heater or a tankless unit, these hot water heaters supply your home with endless amounts of hot water. It brings the hot water to your shower and other appliances by following this simple process:

  1. Water goes into the heater
  2. The water flow sensors identify the strength of the flow of water
  3. The water heater automatically launches the burner
  4. Water then circulates through the heat exchanger
  5. The heat exchanger heats the water to the desired temperature

Once you turn off the hot water tap or the appliance stops running hot water, the tankless heating system will automatically turn off. It’s really that simple.

If you are considering switching your home’s traditional water heater to a tankless water heater, take a moment to weigh out all of the pros and cons of making this switch.

  • Cost: The upfront investment of a tankless water heater is usually a bit higher than a standard water heater. However, it is important to keep in mind the rest of these considerations that seem to make up the difference over time. 
  • Service: Most tankless water heaters require annual servicing and maintenance checks, much like a standard water heater. 
  • Life Expectancy: Typically, on-demand water heaters are intended to last anywhere from 15-20 years.
  • Endless Hot Water: The convenience and comfort of having hot water right when you need it without running out.
  • Efficiency: Tankless water heaters are approximately 40% more efficient than a 50 gallon water tank heater. This means you could save roughly $100 per year in energy usage, meaning it practically pays for itself within the first ten years. (Note: fuel types can have a significant effect on this.)   
  • Compact: Tankless water heaters will save you a significant amount of space, as they are typically mounted to a wall or are installed outdoors. 
  • Incentives: Many utility companies offer incentives and rebates for those who have tankless water heating systems. 

Typically, tankless water heaters have a life expectancy of 15-20+ years. They can last even longer with routine maintenance checks. Standard water heating systems have a life expectancy of roughly 7-10 years for reference.

Tankless water heaters are often referred to as endless water heaters or on-demand water heaters. The main reasons many people prefer them to standard water heaters are:

  • More energy efficient
  • Lower monthly costs
  • Longer lifespan
  • More compact
  • Peace of mind in having an endless supply of hot water

No. Tankless water heaters provide an endless supply of hot water to your home and appliances. Standard water heaters rely on a tank filled with water that takes time to become full and heated. Once the tank runs out, you will have to wait for it to fill and reheat again. Tankless water heaters will never make you wait for hot water!
