How Good are Tankless Hot Water Heaters?

After searching the internet for your new home water heater, you should have come across tankless water heaters and wondering if they are really good. And you are at the right place. So let’s go ahead and have a look at the goodness of these tankless water heaters;

The best way to understand if tankless water heaters are really good is to compare them with traditional storage-type water heaters.

Difference between conventional and tankless water heaters:

Traditional storage-type water heaters store and preheat water in a sealed tank, which reduces loss of heat to some extent. When the temperature of water in the tank goes below temperature set in the thermostat of the heater, the heater re-heats the water again resulting in wastage of energy in the process. Once the water in the tank gets heated it is used for various needs. The tank is refills again and heats the water.

Tankless water heaters on the other hand do not have a water tank as such and hence their name. They heat water as and when there is a requirement (uses a sensing technology). This vastly reduces the energy lost in pre-heating and re-heating as in a traditional water heater.

Now that we have seen the basic difference between a traditional and tankless water heater. Let’s take a look at the pros and cons of the tankless water heater.
