Looking for a new hot water heater replacement option? If you are planning on creating a more energy-efficient home, you might be thinking about switching over to a tankless or Hot Water on-demand water heater system.

What is a hot water on-demand unit?

Unlike the traditional tank-style units, which continuously heat and reheat water, tankless water heaters produce warm water only when you are using appliances. But like any product, there are also downsides that you should consider before committing.  So, what makes more sense—constantly heating water or only when you need to? Read on to learn the pros and cons of hot water on-demand options.

The Pros of installing a hot water on-demand unit

Longer lifespan: One of the main advantages of a tankless system is its long-life expectancy. When compared to more traditional water heaters that last about 10 years, a hot water on-demand unit could last twice as long, saving homeowners the hassles and expenses of more frequent replacement.

Endless hot water: Tankless units heat the water as it flows through the unit, meaning you can shower until your heart’s content. This also makes it an ideal choice for supplying water for larger applications like hot tubs or whirlpools.

Energy savings: Did you know tankless water heaters use about 30-50% less energy than standard tank units? Since they only heat water when you need it, on-demand options are far more efficient, resulting in major savings for homeowners.

Small size: With the soaring costs of real estate, living in smaller homes is becoming the norm for many people. Thanks to their compact size, tankless water heaters take up minimal space, allowing you to make the most of your square footage.

The cons of choosing an on-demand system

Upfront costs: The biggest drawback of going with an on-demand system is the initial price tag. Sure, tankless water heaters run more efficiently than the standard unit, but it could take years to recoup the higher purchase price.

Poor water output: Tankless water heaters win the race over traditional options when it comes to continuous hot water flow—but come up short in the water output department. So, you will be out of luck if you need hot water for multiple uses. If you want the convenience of using a dishwasher and doing laundry at the same time, you may have to purchase additional units.

Hot water on-demand units come with a host of benefits, but they are not for everyone. Taking the time to weigh the pros and cons will help you make the most informed decision possible.

Your climate, the amount of hot water you expect to use, your budget, the lifespan you expect from your home, access to natural gas, the price of electricity or gas in your area, and potentially, government retrofit grants can all factor into your decisions.  In British Columbia, both Fortis and BC Hydro can have various rebate programs for energy-efficient upgrades.
