How a Tankless Water Heater Works
Tankless water heaters work very differently from tanked water heaters and therefore have different parts. Instead of holding hot water in a large tank, the water heater only kicks on when there is a demand for hot water, like when a shower or tap is turned on. So, instead of having to be on all day to keep the water in the tank hot, the tankless water heater is off until it is needed.
Inside the tankless system, a burner ignites when the system signals a need for hot water. The cold water passes over an aluminum heat exchanger and heats the water directly. When the hot water is shut off, the system goes into standby mode. A tankless water heater also has a vent that exhausts any gases outside the home.
Here are some gifs to show how a traditional, tank water heater works as well as how a tankless water heater works.
To help you understand better how a tankless water heater works, here is a list of steps:
STEP 1 - Hot water tap is turned on
The first step to working your tankless water heater is, of course, simply to turn it on. You want to make sure that hot water is flowing through your pipes, this means turning on the hot water. Of course, today that isn’t always a simple explanation. If you have a single knob, be sure to turn it towards the hot water. If you have dual knobs, it’s much simpler. Locate the hot water knob, and turn it to allow the hot water to flow through.
STEP 2 - Water enters the heater
So, now that you have the hot water turned on, what should you expect? With a regular water heater, you expect hot water to travel from the tank through your pipes. However, with a tankless water heater, cold water actually flows through sensors that trigger the internal computer, and begin the heating process.
STEP 3 - Water flow sensor detects the water flow
Now that the internal computer has been triggered, it immediately calculates how the burners need to be, in order to heat the water to the perfect temperature. This can be done with a gas burner or an electrical element. Either way, it provides a constant flow of hot water, without having to wait for a tank to fill back up.
STEP 4 - Computer automatically ignites the burner
So how does the tankless water heater actually provide all that hot water? After the burner begins heating the water, it circulates around a heat exchanger until it reaches its designated temperature. From there, the water exits the tankless water heater and begins traveling through your pipes until reaching its final destination.
STEP 5 - Water circulates through the heat exchanger
With a tankless water heater, you enjoy an endless stream of hot water to use. Once the demand for hot water no longer exists, the tankless water heater automatically shuts down and stops using energy. So, you get to enjoy energy savings along with constant and fresh hot water.
