Everything You Need to Know About Water Heaters

Water heaters are essential household appliances that provide hot water for daily activities such as bathing, washing dishes, and laundry. However, choosing the right water heater can be a challenging task, especially if you are not familiar with the different types and features available in the market.

In this article, we will cover everything you need to know about water heaters to help you make an informed decision when purchasing one for your home.

Types of Water Heaters

There are several types of water heaters available in the market, each with its advantages and disadvantages. Here are some of the most common types of water heaters:

1. Tank Water Heaters

This type of water heater stores hot water in a tank and heats it using gas or electricity. Tank water heaters come in different sizes, ranging from 20 gallons to 80 gallons, and can be installed indoors or outdoors.

2. Tankless Water Heater

Unlike tank water heaters, tankless water heaters heat water on-demand, eliminating the need for a storage tank. They are more energy-efficient and take up less space than tank water heaters.

3. Heat Pump Water Heaters

Heat pump water heaters use electricity to move heat from the air or ground to heat water. They are highly efficient and can save up to 60% of your water heating costs.

4. Solar Water Heaters

Solar water heaters use energy from the sun to heat water. They are the most energy-efficient type of water heater, but they require a lot of space and direct sunlight to function correctly.

Features to Consider

When purchasing a water heater, several features should be considered to ensure that you get the most value for your money. Here are some essential features to keep in mind:

● Capacity

The capacity of a water heater determines how much hot water it can produce. Consider the size of your household and your hot water needs when selecting a water heater.

● Energy Efficiency

Energy-efficient water heaters can save you money on your energy bills in the long run. Look for models with a high energy factor (EF) rating, which measures the efficiency of the water heater.

● Installation Location

Consider the space you have available for installing the water heater. Tankless water heaters take up less space than tank water heaters and can be installed in small spaces.

● Maintenance Requirements

Some water heaters require more maintenance than others. Tank water heaters need to be drained and flushed periodically, while tankless water heaters require regular descaling.

Common Problems with Water Heaters

Like any other household appliance, water heaters can experience problems from time to time. Here are some common problems with water heaters:

  1. No Hot Water: This could be due to a malfunctioning heating element, a faulty thermostat, or a tripped circuit breaker.
  2. Leaking Tank: Over time, the tank of a water heater can corrode and develop leaks. If you notice water around the base of your water heater, it could be a sign of a leak.
  3. Strange Noises: Loud banging or popping noises coming from your water heater could be due to mineral buildup or a faulty heating element.
  4. Pilot Light Won’t Stay Lit: This is a common issue with gas water heaters and could be due to a malfunctioning thermocouple.


Choosing the right water heater for your home can be a daunting task, but with the right knowledge, you can make an informed decision. Consider the type of water heater, features, and maintenance requirements when making your selection.

Additionally, be aware of common problems with water heaters, and schedule regular maintenance to ensure that your water heater is functioning correctly. With the right water heater, you can enjoy hot water whenever you need it while saving money on your energy bills.
