How Tankless Water Heaters Work
Tankless water heaters are a modern and efficient way to provide hot water in homes. Understanding how they work is essential to maximize their benefits and make an informed decision about their installation.
Tankless water heaters operate by heating water on demand, eliminating the need for a storage tank. When a hot water faucet is opened, cold water flows through a heat exchanger inside the unit. An electric element or gas burner then heats the water, delivering a continuous supply of hot water without the wait associated with traditional storage tank heaters.
It's important to note that the flow rate of tankless water heaters is limited. Electric models typically provide hot water at a rate of 2 to 5 gallons per minute, while gas-fired models offer higher flow rates. This means that in larger households or during simultaneous usage, it may be necessary to install multiple tankless water heaters or use separate units for specific appliances.
- Energy efficiency: Tankless water heaters are 24-34% more energy efficient than conventional storage tank water heaters for homes using 41 gallons or less of hot water daily.
- Continuous hot water supply: With on-demand heating, tankless water heaters provide an endless supply of hot water.
- Space-saving design: Tankless water heaters are compact and do not require a storage tank, giving homeowners more flexibility in their installation.
- Longer lifespan: Tankless water heaters generally have a longer lifespan than storage tank water heaters.
- Flow rate limitations: Tankless water heaters have limited flow rates and may not be sufficient for simultaneous multiple uses in larger households.
- Potential higher upfront costs: While tankless water heaters can save money in the long run, the initial purchase and installation costs may be higher than those of storage tank water heaters.
Understanding how tankless water heaters work and their advantages and disadvantages will help homeowners make an informed decision when considering a switch to this modern and efficient water heating technology.

How to Choose a Tankless Water Heater
When it comes to selecting a tankless water heater for your home, there are several important factors to consider. Making the right choice will ensure that you have a reliable and efficient source of hot water that meets your household's needs. Here are the key factors to keep in mind when choosing a tankless water heater:
The size of the water heater should be based on your household's hot water demand. Consider the number of bathrooms, appliances, and fixtures that will require hot water simultaneously. A larger household with higher hot water demand may require multiple tankless water heaters or a whole-house system.
2. Fuel Type
Tankless water heaters are available in both gas-fired and electric models. Gas-fired tankless water heaters generally have higher flow rates and are more suitable for larger households. Electric models are typically smaller and more compact, making them a good option for smaller homes or specific applications like point-of-use water heaters.
3. Energy Efficiency
Energy efficiency is an important consideration to help reduce your energy consumption and lower utility bills. Look for tankless water heaters with higher energy factor (EF) ratings, as these indicate increased efficiency. Additionally, choosing a gas-fired condensing model can further improve energy efficiency.
Consider both the upfront costs and long-term savings when choosing a tankless water heater. While tankless water heaters may have a higher initial purchase price compared to traditional storage tank water heaters, they can provide significant energy savings over time. Factor in installation costs, potential rebates, and estimated operating costs to determine the overall cost-effectiveness.
Factor Considerations Size Hot water demand, number of bathrooms and appliances Fuel Type Gas-fired or electric Energy Efficiency Higher energy factor (EF) ratings, gas-fired condensing models Costs Upfront costs, long-term savings, installation costs, operating costs
By carefully considering these factors, you can choose the right tankless water heater that meets your hot water needs, energy efficiency goals, and budget. Consulting with a reputable plumbing and heating contractor can also provide valuable insights and guidance in selecting the most suitable option for your home.

Whole-House Tankless Water Heater Efficiency Ratings
When considering the efficiency of tankless water heaters, it is important to understand the measurement used to rate their performance. Tankless water heaters are rated based on their Uniform Energy Factor (UEF). The UEF rating indicates the overall energy efficiency of the unit, with higher ratings indicating higher efficiency. This rating takes into account factors such as standby losses, cycling losses, and hot water delivery efficiency.
Gas-fired tankless water heaters typically have UEF ratings ranging from 0.85 to 0.96 for condensing models, which are considered highly efficient. Non-condensing gas-fired models have UEF ratings around 0.80-0.82. In comparison, traditional gas water heaters have UEF ratings ranging from approximately 0.54 to 0.72, indicating lower efficiency. On the other hand, electric tankless water heaters have UEF ratings in the range of 0.91 to 0.93, which demonstrates their energy efficiency.
Hybrid electric/heat pump water heaters, which are gaining popularity for their efficient operation, have impressive UEF ratings ranging from 3.4 to 4.0. These models utilize heat pump technology to extract heat from the surrounding air and transfer it to the water, resulting in significant energy savings. However, it's important to note that hybrid models may have higher upfront costs compared to other types of tankless water heaters.
The UEF rating provides a useful benchmark for comparing the efficiency of different tankless water heater models. By considering the UEF rating alongside other factors such as flow rate, fuel type, and hot water demand, you can make an informed decision when choosing a tankless water heater for your home.
