Tankless Water Heater FAQs

Considering a tankless water heater? Get answers to frequently asked questions about tankless water heaters and connect with reputable installers in USA.

How do I know what size tankless water heater I need?

Sizing a tankless water heater is crucial for ensuring adequate hot water flow. Consider:
  • Peak demand: The number of fixtures that will be used simultaneously.
  • Flow rate: The gallons per minute (GPM) of your fixtures.
  • Ground water temperature: Colder climates require more heating power.
A professional plumber can determine the best size.

How to flush a tankless water heater?

Flushing a tankless water heater involves using a descaling solution to remove mineral buildup. This process typically involves:
  1. Disconnecting the unit from the water and power supply.
  2. Connecting hoses to the cold and hot water ports.
  3. Circulating a descaling solution through the unit.
  4. Flushing with clean water to remove the solution.
  5. Reconnecting the water and power supply.
Consulting a plumber or following the manufacturer's instructions is recommended for a proper flushing procedure.

Where is the best place to put a tankless water heater?

The best location for a tankless water heater depends on several factors:
  • Gas or electric: Gas units require proper venting.
  • Proximity to fixtures: Ideally, install near frequently used hot water fixtures.
  • Accessibility: For maintenance and repairs.
  • Space constraints: Tankless units are smaller than tank heaters, but proper clearances are needed.
  • Climate: Protect from freezing temperatures.
A qualified plumber will determine the best location for your setup.

How to choose a tankless water heater?
