While conventional water heaters dominate the market, tankless water heaters have their advantages, such as their energy efficiency. They’re becoming more popular in recent years because of these advantages. While similar to conventional water heaters, they work differently.

How They Work

Tankless water heaters heat water on demand. They don’t have a large storage tank, unlike conventional water heaters. When a hot water tap is turned on, it heats water and sends it to the tap. They supply an endless amount of water, also unlike conventional waters that can run out of hot water.

Tankless Water Heater Advantages

Since tankless water heaters eliminate standby heat loss, they are much more efficient than conventional water heaters. They have a lower risk of leaking and causing water damage. A tankless water heater takes up less space than a conventional one. This is valuable in a small home.

Tankless water heaters are safer than conventional ones, as there’s no chance they’ll explode. They typically last significantly longer than their conventional counterparts. They’re also less likely to need repairs, and they’re easier to maintain.

Tankless Water Heater Disadvantages

Most tankless water heaters can produce 2-5 gallons of hot water per minute. This means they are limited if hot water demand is too high. They can handle a shower and dishwasher at the same time but are limited after that.

Tankless water heaters have a higher upfront cost than conventional ones as the unit and its installation are more expensive. Since they use electricity, they can’t supply hot water when the power is out.
