Water Heater Buying Guide Posted on September 24, 2019 Hot water is a luxury that many of us take for granted. If your water takes a long time to heat up, or if it is quickly depleted and you’re left shivering in a frigid shower, you likely understand the value of having hot water on demand. This is especially true in winter, or for those who live in colder climates. We’re here to guide you through the best water heaters of 2023 so that you can be well on your way to warmer, more comfortable mornings. Types of Water Heaters Before you purchase a water heater, it is important to understand the different types of hot water heaters available. There are two things to consider here. The first thing to determine is whether you want a tankless water heater or a traditional storage tank unit. Tankless water heaters As the name suggests, tankless water heaters do not use storage tanks. Rather they heat up the water as needed. Tankless models have the advantage of providing hot water on demand and are more energy-efficient, but they can be a bit more expensive upfront. They are also known as on-demand water heaters. Pros: On-demand heating Unlimited hot water More energy-efficient, since they only heat the water as needed More compact Con: Higher upfront cost Limited throughput Storage tank water heaters Storage tank water heaters are good for large families that use several showers at once and have a lower upfront cost. However, they can be less energy efficient and offer a limited supply of hot water in a given time period. Pros: Ideal for larger homes / families Better with simultaneous use Lower acquisition cost Cons: Less energy-efficient No on-demand heating: only a limited amount of hot water is readily available Heat pump water heater These utilize heat from the air to warm up the water. Because they use heat trapped in the space, they are considerably more energy efficient than traditional electric water heaters. However, they require room to work correctly: up to 1,000 cubic feet of uncooled space, and 7 feet of ceiling space. They are also ideal only for warmer spaces or climates, between 40 to 90 degrees Fahrenheit. As heat pump technology continues to improve, more options are becoming available. Some use a separate tank and heat pump that allows for more flexibility. Pro: Up to 60% more energy efficient than electric water heaters Cons: Higher upfront costs Requires space Not ideal for colder regions Indirect water heaters There are also hot water heater systems that connect to a boiler. Also known as indirect water heaters, they use heat from the boiler or furnace. A pipe is connected from the boiler or furnace to the water heater, where a heat exchanger heats the water in the tank. Indirect water heaters are more efficient than fuel-powered water heaters since they use the residual heat from the furnace or boiler, without requiring a separate source of fuel. However, not all furnaces or boilers are compatible. Pros: Energy efficient Lower upfront cost Faster recovery time Cons: Not compatible with older furnaces or boilers Requires space Not ideal for areas with hard water For more information on water heater models, check out our guide to The Different Types of Hot Water Heaters. Hot Water Heaters by Fuel Type The second thing you’ll want to decide is fuel type for the water heater. The three main fuel types are: Natural gas – lowest cost Liquid propane – higher cost, but more environmentally friendly Electric – least expensive to install, but less efficient than and more expensive over the long term Each has its own pros and cons and are dependent on the type of power source or fuel supply you have installed at home, whether it’s a gas line, LPG, or electrical main. Sizing When shopping for a hot water heater, you will want to consider other factors such as cost, efficiency, and the size of your household. It’s also very important to purchase an appropriately sized system for your needs. Our water heater sizing guide is a handy resource for finding the right size needed for your home. Now that you have a better understanding of the different types available out there, we’ll narrow down the best water heaters of 2023 by category. What is the Average Cost to Replace a Water Heater? The average cost to replace a water heater depends on the design. Tankless are more expensive than storage tank models. Tankless water heaters range in price from $839 to upwards of $2,000. On the other hand, storage tank systems vary widely in price due to the tank size. Typically, the larger the tank, the more expensive the product. Smaller storage tank water heaters (i.e. less than 19 gallons) range in price from $450–$570. Larger storage tank systems (i.e. 40 or more gallons) typically fall in the $500–$2,000. However, keep in mind that efficiency and technological advancements can also impact the cost of storage units. Expect to pay more for higher end products compared to the more basic options. The Best Water Heaters of 2023 Rising fuel costs and their consequent effect on utility bills are the main concern of homeowners this year. As such, cost and efficiency are the primary considerations to look at when choosing a new water heater for 2023. Other factors to consider include BTU and flow rate.
