Tankless water heaters, also called on-demand water heaters, produce hot water only when needed. Although storage tank heaters are the most common, tankless water heaters are steadily gaining prominence and market share.

How Do Tankless Water Heaters Work?

Tankless water heaters heat water directly. These appliances do not have a tank attached to them. Instead, they have a pipe connected to the hot water tap, which, when turned on, channels cold water directly into the unit.

These water heaters are equipped with either gas burners or electric elements to heat the water and constantly supply hot water. Although, the flow rate limits their output.

How Much Water do they Produce?

It's vital to note that tankless water heaters equipped with gas burners have a greater flow rate than their electric counterparts. Most tankless water heaters produce 2-5 gallons of hot water per minute. Tankless water heaters are well-suited to small households. However, they struggle to meet water demands when there is the simultaneous use of hot water. In such circumstances, you may need to install multiple tankless water heaters at every hot water outlet. Connecting them in parallel will also allow for concurrent use.

Why Opt for Tankless Water Heaters?

Tankless water heaters provide innumerable benefits compared to storage tank heaters.


Tankless water heaters require less space than standard storage tank heaters. Storage space is coveted in homes, and traditional storage heaters require too much space, which can also impact property value if you wish to sell your house in the future.


Tankless water heaters have an average lifespan of 20 years, double that of traditional storage tank heaters. Although tankless water heaters are more expensive than traditional ones, manufacturers also provide a lengthy warranty for tankless water heaters, making them a wiser investment in the long run.

Energy Efficiency

Tankless water heaters offer excellent energy efficiency. A small household that uses less than 41 gallons of hot water daily can experience 30% more energy efficiency from tankless water heaters than traditional storage tank heaters. Tankless water heaters also provide 8-14% more energy efficiency for larger households that consume up to 86 gallons of hot water. Energy efficiency translates into lower utility bills, which means that while tankless water heaters may be more expensive initially, they are the most cost-effective option in the long run.

Convenience On Demand

Tankless water heaters provide hot water on demand. Traditional storage tank heaters have a storage unit that can hold a certain amount of water. If someone in your household uses the shower before you, they may empty the tank, requiring you to either take a cold shower or wait for the tank to fill up before you can access hot water. This situation can be an issue in households with shared bathrooms. However, a tankless water heater avoids this dilemma as hot water is provided when the faucet is turned on. In this case, the lack of a tank proves beneficial as it eliminates waiting time.

Cleaner Water

Traditional heaters store water in tanks. Water can sit in the tanks for long periods if not used, which can cause sediment build-up and rust from the tank's interior to contaminate the water. On the other hand, tankless water heaters don't pose this issue because there is no storage tank.
