What is a tankless water heater?

Tankless water heaters are an increasingly popular alternative to traditional storage tank water heaters, as they provide hot water whenever you need it without taking up nearly as much space.

Should you buy a tankless heater?

As said above, a tank heater is much lower in the upfront cost (the unit and installation cost); also, you’ll have hot water instantly as turning on the tap. When it comes to a tankless heater, you have to wait a while for the hot water to reach the tap; it also costs much higher when buying and installing a tankless heater.

Are tankless heaters more energy efficient?

Electric tankless heaters are more energy efficient and have lower operating costs, but they may not be able to meet the hot water demands of larger households. Natural gas and propane tankless heaters have higher energy costs, but they can handle the hot water needs of larger households.
