How do I choose the right tankless water heater for my home

May 15, 2023


While storage tank water heaters are still the most common type of water heater installed in American homes today, these systems do have hot water supply limitations and require a significant footprint when installing a whole-home system. Alternatively, tankless water heaters feature a small physical footprint and endless hot water for your home, particularly if you tend to use hot water for long periods of time and worry about running out of the supply kept in a storage tank. If you’re planning to make the switch to a tankless water heater for greater efficiency and space savings, schedule a professional plumber to help choose what equipment and location will work for your home. Call us today 844-216-9300 so we can schedule you for a no cost appointment.

Determine Your Water Usage

Tankless water heaters aren’t rated by storage capacity; instead, they are rated by flow rate, which measures the amount of water that can be heated as it flows through the device. Thus, the flow rate of your tankless water heater should match the amount of hot water you expect to simultaneously use in your home at any given time. Making sure your tankless water heater can provide the flow rate you need will ensure that you can use multiple hot water taps at once, such as running a washing machine or dishwasher while allowing a family member to take a hot shower. Your plumber can help you determine the flow rate used by all the appliances and fixtures in your home, then evaluate your typical hot water usage to calculate the flow rate your tankless water heater will need.

Determine Your Temperature Rise

Tankless water heaters work by heating water quickly from its incoming temperature to the temperature you want. This difference is called temperature rise, and affects how efficient the water heater is at its job. Your plumber can also help you calculate the temperature rise needed in both the summer and the winter to ensure your water is the temperature you want, then translate this temperature rise to a tankless system capable of delivering the amount of heating you want quickly and efficiently.

Determine Your Appliance Needs

Tankless water heaters are available as whole-home systems or point-of-use appliances, depending on the amount of hot water you want the unit to provide. Whole-home tankless water heaters are typically larger and are designed to meet your hot water needs throughout your home. Point-of-use tankless water heaters are meant to provide hot water to a dedicated faucet or fixture to eliminate wait times and further reduce energy usage. You can install multiple whole-home or point-of-use systems in sequence to meet your hot water requirements, or simply choose a whole-home or point-of-use system with the capacity you need. The best configuration for your home will depend on both your hot water needs and your budget; your plumber can help you make the right decision prior to scheduling tankless water heater installation.
