What is a Water Heater? 

Well, the name itself should let you understand what it is designed for. A water heater is an equipment that heats up the water so that it is best suited for a shower or other regular purposes. The water coming from your tap or the municipal water supply may be too cold, depending on the season of the year. To make the water suitable enough for a shower, you need to get it heated up.

A water heater is generally in the form of cylinders or drums. They come with a drum filled with water and a heating mechanism inside the drum or at the bottom of the heater. A water heater does exactly what it means through its name – it heats the water. It just takes up the water from your water supply pipe and then warms it up. The water heaters can also be used to make your water potable.

How is a Water Heater Beneficial?

The water heater comes with its own benefits. Of course, the actual performance and advantages of a water heater would ideally be dependent on the type of heater you choose. The right choice should ideally be dependent on the actual budget and requirements that you have. 

The water heater ideally comes in two types – Storage Water heaters and Tankless water heaters. The storage water heaters are quite common and come with a storage tank. They will heat and store the water. The tankless water heaters do not come with any storage facilities. 

The significant advantages offered by a water heater can include:

  • The tankless water heaters consume a considerably lower amount of energy.
  • They consume minimal space with not much installation costs. 
  • The water heaters come with a life expectancy of a minimum of 20 years
  • The water heaters induce a habit of water conservation. You would save water and use it only when needed. 

The electric water heaters come with a lower initial cost. Of course, the cost will be dependent on the size and type of water heater you have chosen. Moreover, they are highly efficient. Electric water heaters do not have a venting process in their functionality. That is precisely what would make it one of the best options and a capable performer.

When you compare them to the gas-based water tankers, you may experience issues like gas leakage. That is exactly why it is important to give a thought to the best options for analysing what brand of water heater is the most reliable. 

The best factors to consider while choosing a water heater for your house- A Buying Guide 

Like with any other product, the water heater too comes with its own set of buying factors. A sort of checklist for the best water heater, these factors would help you make a well-informed choice in choosing the best water heater.

1. Energy Efficiency2. Water Capacity3. The Rate of Flow4. Temperature Control Options5. Ease of Installation and Maintenance
The energy efficiency ratings vary for both gas heaters and electric heaters. However, the higher ratings in both cases would mean increased heating levels with minimum energy consumption. It would be a good idea to check the energy efficiency levels and pick a heater with the maximum rating.

The hot water capacity would be dependent on the family size that the heater is designed to provide services to. In case you have a large family, the water heater you choose would need to meet the exact needs of your family. The best option you would need to choose would be around 40 to 50 gallons. 

According to the suggestions from U.S. Department of Energy’s Energy Saver website, the right options would be as per the details here: 

  • Shower – 10 gallons
  • Shaving – 2 gallons
  • Dishwashing – 4 Gallons
  • Washing clothes – 7 Gallons

This guide can help you choose the right capacity for your needs. 


Some heaters are known to reduce the water flow rate for providing hot water. If that happens in your case, it can be a little annoying. Especially in case you are using the hot water for showers. The Flow rate is typically indicated in gallons per minute. The ideal flow rate for a standard home requirement should hover around 5 gallons per minute.
Most of the water heaters do not offer the temperature control options. If you are looking to have hot water with differential temperature, it may be essential to check out a model with an option for a variable temperature. Check for the options in the form buttons or a slider for setting up your desired temperature.

The installation process for most of the water heaters is simple and more comfortable. If you are replacing your existing water heater, choosing it should not be a concern. In case you are planning to install the heater yourself, check for the more comfortable installation options.

All water heaters need at least a minimal level of maintenance. The constant requirement for maintenance may not be a viable option in many cases. If you already have a busy schedule, you would perhaps prefer a water heater with minimum or no maintenance.
