Things you need to keep in mind while buying a Tankless Water Heater

What is a Tankless Water Heater?

Tankless water heater is nowadays getting popular due to their power-saving capacity, unlike other traditional water heaters they do not need to store water and continuously heat it until it is used.

They heat it without storing, in which water continuously flows through and gets heated.

Things to keep in note while buying a Tankless Water Heater?

In several ways, there is less room for error while selecting a tankless water heater. Unlike a traditional water heater that stores a reserve of hot water in a storage tank, a tankless unit doesn't have this limitation to fall back on. If a tankless water heater is not able to heat the water as it passes through the unit, the water delivered at the tap will be lukewarm.

Here are a few important things you should consider while choosing a tankless water heater:

Energy Efficient Tankless Water Heaters

Energy saving is one of the main benefits of porting to a tankless water heater but then also it might be a factor that you should pay close attention

Water heaters are one of the appliances which use Energy factor (EF) rating to know one unit’s capacity:

  • Energy Factor (EF) can be defined as a measurement of a water heater's overall efficiency.
  • It is determined by the useful energy that is coming from the water heater.​
  • The number obtained is then divided by the amount of energy (gas or electricity) that went into the water heater to heat the water.
  • The rating is based on the amount of hot water produced by a single unit of fuel consumed.
  • Higher the EF rating more is the efficiency of the water heater.

The EF rating, however, does not tell the whole story when it comes to operating costs. Electric on-demand systems have more EF ratings than gas units, but as gas is present is less expensive fuel source than electricity, gas units tend to deliver a lower operating cost.


As we talk about Warranties it varies from manufacturer-to-manufacturer and model-to-model. Many manufacturers require that you register or install your tankless water heater by professionals to be eligible for warranty coverage.

It is an important part of selecting a tankless system. When a manufacturer stands behind their product with reasonable warranty time frames and procedures, it's a good indication that they believe in the quality and reliability of the unit they're selling.

Many manufacturers offer coverage such as:

  • Heat exchanger: 10-15 Years
  • Parts: 2-5 Years
  • Labor: 12 months


By determining the temperature size manufacturers size their units needed to achieve a specific flow rate. Once you calculate these 2 factors for your household, you'll be able to select a tankless water heater system that best meets your family's hot water demands.

One can expect your tankless water heater to deliver between 2 to 5 gallons (flow rate) of hot water per minute. On-demand systems that are fueled with gas, tend to be able to produce a higher flow rate than electric systems.


So this was all about Tankless Water Heaters you need to know. There are also Immersion rods but they take more time to heat the water and require a lot of electricity so, you're better off with a geyser!
