Different types of hot water heaters accomplish different things. Your water heater is one of the most critical appliances in your home. It provides hot water for cooking, bathing, and cleaning. Water heaters have come a long way in the past decade, and there are now many different design features to choose from. How do you know which one is right for you? We’ll help you know the different types of water heaters and tips on choosing the right one for your needs.

Types of Hot Water Heaters

The first step before purchasing is to understand the different water heaters available today.

Conventional Storage Water Heaters

The conventional storage water heater is the most common type and is adequate for everyday use. It includes a hot water storage tank that could be between 30 and 80 gallons. These water heaters are affordable and low maintenance. However, they require a significant amount of space and are low on energy efficiency. A conventional storage water heater has a lifespan of 10 to 15 years.

Tankless Water Heaters

Tankless water heaters heat water directly without using a storage tank. It heats water only on demand. One of its most significant advantages is that it provides an adequate water supply without running out, unlike conventional storage water heaters. These water heaters are also energy-efficient and have a longer lifespan of around 20 years. A limitation of tankless water heaters is that they may seem expensive upfront.

Heat Pump Water Heaters

This type of water heater provides hot water by moving heat from one place to another instead of generating heat directly. This results in high energy efficiency and significant cost savings. It is also safe and environmentally friendly.

Solar Water Heaters

Solar water heaters use the free and limitless source of energy – the sun, to provide hot water. The most significant advantage of using solar water heaters is energy savings. They are very economical, need little maintenance, and are environment friendly. Since they come with high installation costs, the federal government offers tax incentives and rebates to those who choose to install solar water heaters.

Indirect Water Heaters

Indirect water heaters use a home’s space heating system to heat water. Sometimes they are also called integrated or combination water and space heating systems. (Carrick, 2021)

Water Heater Design Features to Consider When Replacing Your Water Heater

When it comes to design features, there are several things to consider.


The water heater’s capacity is crucial, as it must be sufficient to meet the needs of your home. The capacity required will depend on the size of your home and the number of people who live there. Determine how much hot water your family uses daily, which will help you choose the suitable capacity for you.

Type of Fuel

The fuel you use for the water heater directly impacts its operating costs and energy efficiency. It’s an excellent time to compare fuel costs between electric and gas water heaters.

Tank or Tankless

Tankless water heaters provide hot water on demand, so you don’t have to wait for the water to heat up. They are more expensive than traditional water heaters, but they can save you money in the long run.

Energy Efficiency

Water heating accounts for a significant amount of home energy use. Before making the purchase, check the energy efficiency of the water heater. If your water heater is over ten years old, it might be time for a replacement. Choosing an energy-efficient model will result in energy and cost savings. (Energy.gov)
