Tankless Water Heater Installation Glossary

Understanding key terms related to tankless water heaters can help you make informed decisions.

Tankless Water Heater

A tankless water heater, also known as an on-demand water heater, heats water only when you need it, rather than storing hot water in a tank. Tankless systems save money over time by reducing energy consumption.

Tank Water Heater

A traditional water heater heats a stored volume of water to the set temperature. {These units are typically less expensive to purchase than tankless water heaters, but their operating costs are higher, because energy is wasted when heating water that isn't immediately used.

Condensing Tankless Water Heater

A type of tankless water heater that achieves high efficiency through exhaust heat recovery.

Non-Condensing Tankless Water Heater

A type of tankless water heater which doesn't recover exhaust heat, thus making them slightly less energy-efficient than condensing units.

EF (Energy Factor)

The EF rating helps determine the overall efficiency of the system. Higher EF ratings indicate greater efficiency.

Uniform Energy Factor (UEF)

A measure of a tankless water heater's efficiency in converting energy to hot water. Similar to EF, a higher UEF rating means lower operating costs.

Flow Rate

The maximum volume of water a system can heat GPM. It is an important factor to consider when sizing a tankless water heater for your household or business needs.

Activation Flow Rate

The amount of water usage required to activate a tankless water heater. If the water flow is below the activation flow rate, the unit will not ignite and produce hot water.

Temperature Rise

The difference between the temperature of incoming water versus outgoing heated water. The temperature rise is used to calculate the size of tankless water heater for sizing a tankless water heater.

Venting

Tankless water heaters require an exhaust system. The best approach depends on the heater type and the home layout. Consult with a professional regarding venting and system installation.

Gas Supply

Gas-fired tankless water heaters need a natural gas or propane supply. If you are converting from an electric water heater to gas, this may require additional plumbing work to run a gas line to the installation location.

Water Quality

The quality of your water can affect the performance and lifespan of a tankless water heater. Hard water can cause mineral buildup and scale formation in the heat exchanger, reducing efficiency and potentially causing premature failure. A water softener can help to reduce mineral buildup in the unit.

Recirculation System

A hot water recirculation system keeps hot water constantly circulating through a dedicated loop of plumbing, so that hot water is readily available at your faucets and fixtures without having to wait for the water to heat up. It can be integrated with a tankless water heater for even greater efficiency.

Point-of-Use Water Heater

A small tankless water heater installed near the appliance it services, such as a sink or shower, to provide hot water on demand at that location. This eliminates the wait for hot water and minimizes water waste in long pipe runs.

Load Calculation

A load calculation determines the hot water demand based on the number of fixtures, the size of the property, and estimated use. This assessment is used to determine the appropriate size and flow rate of a tankless water heater.
