How a Tank Storage Water Heater Works
Most homeowners in the Yukon & Oklahoma City area have a traditional tank storage water heater in their homes. These models heat several gallons of water at a time, using either electricity or gas.
- Hot water is stored in a large tank until needed.
- The water cools over time, so it must be reheated.
- Once the tank runs out, you have to wait for more hot water.
How a Tankless Water Heater Works
A tankless water heater, or on-demand heater, also uses electricity or gas as the heat source. Instead of heating a lot of water ahead of time, a tankless system heats water only as it’s being used.
- A flow sensor turns on the burner when water enters the heater.
- The burner heats the water as it passes through.
- Hot water comes out at your preset temperature – no storage tank needed.
Signs You May Need a New Water Heater
- Water does not stay hot
- Rusty or discolored water
- Unusual noises
- Water leaking around the unit
- Rising energy bills
- The current unit is getting old
