The Ultimate Guide to Choosing a New Water Heater for Your Home

A reliable supply of hot water is integral to a comfortable and functional home, and the right water heater can make all the difference. Whether you are moving into a new home, planning a renovation, or your current unit is at the end of its lifespan, selecting a new water heater requires careful consideration.

Types of Water Heaters

There are several types of water heaters available, each with its own set of advantages and limitations. Before making a decision, it’s important to understand the differences between them to find the one that will best suit your needs.

Tank Water Heaters

Tank water heaters are the most common type found in homes. They store and preheat water in a tank using gas or electricity, then dispense it to various outlets when needed. One of the main benefits of a tank water heater is its relatively low upfront cost. However, they can be less energy efficient than tankless models because they continuously heat water, which can lead to standby heat loss.

Tankless Water Heaters

Tankless, or on-demand, water heaters do not store hot water. Instead, they heat water as it’s needed, which can offer significant energy savings. Tankless water heaters are typically smaller than tank models, which means they can be a space-saving option. However, the upfront cost is usually higher, and they may not be suitable for homes with high simultaneous hot water demands.

Heat Pump Water Heaters

Heat pump water heaters move heat from the air around the unit to the water, making them two to three times more energy-efficient than conventional electric water heaters. While they can be more expensive to purchase, they cost less to operate, making them a great long-term investment.

Solar Water Heaters

Solar water heaters use the sun’s energy to heat water, either through direct or indirect methods. They can be costly to install but are very efficient and can result in substantial long-term savings on energy bills. Solar water heaters are also environmentally friendly, emitting no greenhouse gases during their use.

Factors to Consider When Choosing a Water Heater

To find the right water heater, there are several factors to consider that go beyond the type of system. Each of these points will impact your hot water experience and the overall efficiency of your home.

Family Size and Usage Patterns

The size of your household and how you use hot water will help determine the type and size of water heater that’s right for you. A larger family or a home with multiple bathrooms and high hot water demand may require a system that can deliver large quantities of hot water quickly and efficiently.

Energy Efficiency and Operating Costs

Choosing an energy-efficient water heater can lead to substantial savings on your energy bill over the long term. Look for models with higher Energy Factor (EF) ratings, which indicate better efficiency. Consider the initial purchase price in conjunction with the estimated annual operating costs to truly understand the long-term value.

Available Space and Installation Requirements

The physical space in your home and the technical requirements for installation will restrict your choices. Tankless water heaters, for example, require proper ventilation and electric systems capable of handling their output. Conversely, large tank water heaters will need ample space for both the unit and the clearance required by local building codes.

Installation and Maintenance

Proper installation of your water heater is key to its efficiency and safety. A professional installation ensures that all plumbing, electrical work, and venting are done correctly. Once installed, regular maintenance such as flushing the tank, checking the anode rod, and inspecting for leaks will extend the life of your water heater and keep it operating at peak efficiency. A professional water heater service in Kaysville can provide annual inspections, perform necessary cleanings, and address any repairs early to prevent larger issues down the line.

Understanding Energy Efficiency Ratings

Shopping for water heaters can be overwhelming with the variety of models and features. One effective way to compare energy efficiency is to look for the Energy Star label. Energy Star water heaters meet strict energy efficiency criteria set by the U.S. Environmental Protection Agency (EPA) and the Department of Energy (DOE).

Water heaters are labeled with an Energy Factor (EF) that determines overall efficiency. The higher the EF, the more efficient the water heater. Understanding and comparing these ratings can help you make an informed decision that aligns with your energy-saving goals.

Budgeting for a New Water Heater

Cost is a significant consideration for most homeowners. When budgeting for a new water heater, it’s important to consider the initial purchase price as well as installation costs, operational costs, and any long-term savings associated with energy efficiency.

Tank water heaters typically have lower upfront costs than tankless, heat pump, and solar models. However, these savings may be offset by higher operational costs. Solar and heat pump water heaters can qualify for federal tax credits, and local utility companies sometimes offer rebates for purchasing energy-efficient models, which can help mitigate the initial investment.


Selecting a new water heater is an important decision that can impact your home’s comfort, energy usage, and finances for many years. By considering the factors outlined in this guide, you can make an informed choice that meets your household’s specific needs and preferences. Remember to prioritize efficiency and consult with a professional to ensure the best outcome for your new water heater installation. With the right information and guidance, you’ll be well on your way to enjoying hot water that’s both plentiful and sustainable.
