Pros of tankless water heater
Long-term Energy and Cost Savings
The biggest advantage of this appliance is that they can save you money because of their energy efficiency. Heating the water only when it is necessary prevents the standby heat loss, which is noticed in a tank-style water heater.
Unlimited Hot Water
An endless supply of hot water can be obtained with this appliance if the water usage is below the maximum flow rate. It is nothing but the ability to heat a certain amount of water at a given time. This is advantageous if a hot water supply is needed continuously.
This appliance enables effective usage of limited space, especially if you have less space in your home. Generally, they are mounted on the wall, requiring less space when compared to the conventional tank-style water heaters.
An average unit measures around 27×18×10 inches.
Low Risk of Leaks
The biggest risks with the conventional tank-style heater are that the possibility of mineral build-up inside the tank is high, leading to corrosion and leaks. Because tankless water heaters have no tank itself, this risk can be eliminated. But it doesn’t mean that they are completely immune to problems. Without proper maintenance, there are chances of leakage, but it’s quite low.

These tankless water heaters can last over 20 years, whereas the tank-style water heaters can last only 8-12 years. Given its life expectancy, it is a wonderful investment with no regular replacements.
Cons of tankless water heater

If a storm comes and cuts off the power supply, it has also stopped hot water supply. So, the bottom line is that if power fails, then there’s no hot water. On the other hand, the tank-style water heaters can store hot water in their tank for several days.
Tankless water heaters are loaded with advantages over the conventional tank-style water heaters mainly because they save money in the long run, unlimited hot water, compact, and they never leak. The best part is that they can last twice as long as the tank-style water heaters.
