Tankless Water Heater Buying Guide
When it comes to choosing a tankless water heater, there are several important factors to consider. These factors will help you find the perfect unit that meets your specific needs and preferences. In this buying guide, we will discuss the key factors to keep in mind while making your decision.
Power Source: Electric or Gas
One of the first decisions you'll need to make is whether you want an electric or gas-powered tankless water heater. Electric tankless water heaters are generally more affordable upfront and easier to install. However, they are less efficient and may struggle to deliver hot water to multiple fixtures simultaneously. On the other hand, gas-powered tankless water heaters are more energy-efficient and can handle higher demands. However, their installation tends to be more complex due to venting requirements and professional expertise.
Flow Rate
The flow rate is another crucial factor to consider. It represents the amount of hot water the tankless water heater can deliver per minute. The flow rate you need depends on the number of appliances or fixtures you want to supply with hot water simultaneously. It's essential to choose a tankless water heater with a flow rate that can meet your household's peak demand without compromising water pressure or temperature.
Temperature Rise
Temperature rise refers to the increase in water temperature that the tankless water heater can achieve. It's the difference between the desired hot water temperature and the temperature of the incoming cold water. Understanding the temperature rise is vital to ensure that the tankless water heater can provide hot water at the desired temperature consistently.
By taking into account these factors and considering the specific requirements of your household, you'll be able to make an informed decision and choose the right tankless water heater. Remember to also consider factors like warranty, size, and installation requirements to ensure a seamless and efficient hot water solution for your home.
The Right Size Tankless Water Heater
When it comes to choosing the right size tankless water heater for your home, it's important to consider two key factors: flow rate and temperature rise.
The flow rate is the amount of hot water your tankless water heater can provide per minute. This is determined by the number of devices you expect to use simultaneously, such as showers, faucets, and appliances. It's essential to calculate the total flow rate required to meet your household's hot water needs.
The temperature rise is the difference between the desired water temperature and the incoming ground water temperature. For example, if you want your hot water to be at 120°F and the ground water temperature is 50°F, the temperature rise is 70°F. A higher temperature rise requires a tankless water heater with a higher heating capacity.
Household Size Flow Rate (GPM) Temperature Rise (°F) Recommended Tankless Water Heater Small (1-2 people) 2-3 25-35 EcoSmart ECO 11 Electric Tankless Water Heater Medium (3-4 people) 4-6 35-45 Stiebel Eltron Electric Tankless Water Heater Large (5+ people) 6+ 45+ Rinnai Indoor Gas Tankless Hot Water Heater
A tankless water heater that is too small for your household's hot water demands will struggle to keep up with the required flow rate, resulting in inadequate hot water supply. On the other hand, a tankless water heater that is too large may be unnecessary and potentially wasteful, as it will consume more energy to heat water that is not being used.
By considering both the flow rate and temperature rise, you can select the right size tankless water heater that will meet your hot water needs efficiently and effectively.

Types of Tankless Water Heaters
Tankless water heaters come in different types to suit various needs and preferences. Understanding the different types can help you make an informed decision when selecting the right one for your home. The three main types of tankless water heaters are whole-house tankless water heaters, point-of-use tankless water heaters, and condensing tankless water heaters. Let's explore each type in more detail:
1. Whole-House Tankless Water Heaters
Whole-house tankless water heaters are designed to provide hot water for the entire home. They have a high flow rate and can handle multiple hot water demands simultaneously. These units are typically installed centrally and are capable of delivering hot water to multiple fixtures and appliances throughout the house, including showers, sinks, and washing machines. Whole-house tankless water heaters are ideal for larger households with a high demand for hot water.
2. Point-of-Use Tankless Water Heaters
Point-of-use tankless water heaters are smaller units designed to provide hot water to a single appliance or fixture. These units are often installed closer to the point of use, such as under the sink or near a shower, to eliminate the need for long hot water pipes. Point-of-use tankless water heaters are perfect for smaller homes, apartments, or specific areas where hot water is needed, like a guest bathroom or kitchen.
3. Condensing Tankless Water Heaters
Condensing tankless water heaters are highly efficient units that extract and capture heat from the unit's exhaust gases. This process maximizes energy efficiency and reduces heat loss, making them an excellent choice for homeowners looking to reduce energy consumption and save on utility bills. Condensing tankless water heaters are available in both whole-house and point-of-use models, providing versatility and energy savings for any household.
In addition to these types, there are also recirculation water heaters that use a recirculation system to constantly circulate hot water throughout the home, ensuring instant hot water at each tap. This can eliminate the need to wait for hot water and reduce water wastage. Consider the needs of your household, the layout of your home, and your desired energy efficiency when choosing the type of tankless water heater that is right for you.
Type Key Features Recommended For Whole-House Tankless Water Heaters - High flow rate- Multiple hot water demands- Central installation - Larger households- Homes with high hot water demand Point-of-Use Tankless Water Heaters - Single appliance or fixture- Close to point of use - Smaller homes- Apartments- Specific areas with hot water needs Condensing Tankless Water Heaters - High energy efficiency- Heat capture from exhaust gases - Energy-conscious homeowners- Any household seeking energy savings Recirculation Water Heaters - Constant hot water circulation- Instant hot water at each tap - Homes with no wait time for hot water- Reduction in water wastage
Other Factors to Consider
When choosing a tankless water heater, there are several other factors to consider that can help you make the right decision for your home. These factors include the type of home, frequency of use, and fuel type.
Home Type
The type of home you have, whether it's a new construction or an existing build, can impact your choice of tankless water heater. New constructions may have more flexibility in terms of installation options, while existing builds may require more consideration for retrofitting.
Frequency of Use
Consider how often you will be using hot water and how many people will be using it simultaneously. This will determine the flow rate and capacity you need from your tankless water heater. If you have a large household with multiple bathrooms, a higher flow rate may be necessary to ensure everyone has access to hot water when they need it.
Fuel Type
There are different fuel types available for tankless water heaters, including natural gas, liquid propane, and electric. The fuel type you choose will depend on factors such as availability, cost, and installation requirements. Natural gas and liquid propane heaters tend to have higher flow rates and are more suitable for larger households, while electric heaters are often more compact and easier to install.
By considering these factors alongside the specifications and features of different tankless water heaters, you can make an informed decision that meets your specific needs and preferences.
