Choosing the right water heater for our home is an important decision. A good water heater provides reliable hot water for our daily needs and operates efficiently to save energy and money. With various options available, picking the right one can seem overwhelming. However, understanding the main factors that affect our choice can help us make an informed decision.

We need to consider several key aspects, such as the types of water heaters available, their energy efficiency, the correct size for our household, and the installation and maintenance requirements. Each of these factors plays a crucial role in determining the best water heater for our home. By taking the time to evaluate these elements, we can select a water heater that meets our needs and fits our budget.

In this article, we’ll dive into the process of choosing the right water heater for our home. We’ll look at different types of water heaters, discuss how to evaluate their energy efficiency, determine the correct size, and consider installation and maintenance needs. Understanding these aspects will guide us in picking the most suitable water heater for our household.

Understanding Different Types of Water Heaters

Choosing the right water heater starts with understanding the different types available. The most common types include tankless, storage tank, heat pump, solar, and condensing water heaters. Each type has its own set of advantages and disadvantages, and the best choice depends on our specific needs and circumstances.

Tankless water heaters, for example, heat water on demand, providing endless hot water and saving space because they don’t require a storage tank. However, they can be more expensive to install. Storage tank water heaters are more traditional and store hot water in a tank, making them more affordable initially, but they tend to use more energy to keep the water heated all the time. Heat pump water heaters use electricity to move heat from the air or ground to heat the water, which makes them very energy-efficient but also more costly upfront. Solar water heaters use energy from the sun, offering significant energy savings but requiring adequate sunlight and higher initial installation costs. Condensing water heaters are highly efficient and use the heat from exhaust gases to heat the water, but they are less common and might be pricey to install.

Evaluating Energy Efficiency

Energy efficiency is a critical factor when choosing a water heater. More efficient water heaters can save us money on energy bills and reduce our environmental impact. The Energy Factor (EF) rating helps us compare the efficiency of different water heaters. The higher the EF rating, the more efficient the water heater is.

To evaluate energy efficiency, we should look for water heaters with the ENERGY STAR label. These units meet strict energy efficiency guidelines set by the Environmental Protection Agency. Tankless water heaters, for example, tend to be more energy-efficient because they heat water only when it’s needed, eliminating the standby heat losses associated with storage tank models. Heat pump water heaters also have high-efficiency ratings due to their method of transferring heat rather than generating it directly.

It’s important to consider both the initial cost and the long-term savings when evaluating energy efficiency. Although efficient models can be more expensive upfront, the savings on energy bills over time can make them a more cost-effective choice. Understanding the energy requirements of our household and comparing the EF ratings and operating costs of different models can guide us in selecting the most energy-efficient water heater for our needs.

Sizing Your Water Heater Correctly

Choosing the right size water heater for our home is essential for ensuring it meets our hot water needs efficiently. An undersized water heater may run out of hot water quickly, while an oversized one can lead to higher energy bills and unnecessary expense. To determine the right size, we need to consider the peak hour demand of our household.

For storage tank water heaters, the first-hour rating (FHR) helps us understand how much hot water the heater can supply in an hour of use. To calculate our peak hour demand, we can add up the total gallons of hot water used during the busiest hour. This includes showers, dishwashing, laundry, and other hot water activities. For example, if our peak hour demand is 40 gallons, we should look for a water heater with an FHR close to that number.

For tankless water heaters, sizing is based on the flow rate and the temperature rise needed. The flow rate is measured in gallons per minute (GPM). We should add up the flow rates of all fixtures we expect to use simultaneously—like a showerhead, sink, and washing machine. If our fixtures total 5 GPM and we need a temperature rise of 40 degrees Fahrenheit, we’ll need a tankless water heater that can handle these specifications. Correctly sizing our water heater ensures it meets our needs without wasting energy.

Considering Installation and Maintenance Needs

Installation and maintenance are crucial factors to consider when choosing a water heater. Proper installation ensures our water heater operates efficiently and safely. Some types of water heaters, like tankless or solar models, may require more complex installations compared to traditional storage tank units. These installations often need professional expertise, which can add to the overall cost.

Maintenance is equally important to ensure the longevity and performance of our water heater. Regular maintenance tasks include flushing the tank to remove sediment build-up, inspecting the anode rod, and checking for leaks. Tankless water heaters may need periodic descaling to prevent mineral build-up inside the unit. By understanding the maintenance requirements of different water heaters, we can choose one that fits our ability and willingness to perform these tasks or budget for professional maintenance services.

Additionally, considering the location of the water heater can impact both installation and maintenance. Water heaters must be installed in areas that can support their weight and allow for proper ventilation if required. Ensuring easy access for maintenance tasks can save time and hassle in the long run. By taking installation and maintenance needs into account, we can make a more informed choice that ensures long-term satisfaction with our water heater.


Selecting the right water heater for our home involves careful consideration of various factors, including the type of heater, its energy efficiency, proper sizing, and the installation and maintenance requirements. Each of these aspects plays a significant role in ensuring our home has a reliable and efficient supply of hot water.

By understanding the different types of water heaters and evaluating their energy efficiency, we can select a model that fits our needs and helps save on energy costs. Correctly sizing our water heater ensures it can handle our peak demand, and considering installation and maintenance needs helps us prepare for the long-term upkeep of the unit.
