75 gallon, gas State Select water heater with blower. Should the blower run all the time? If not when and why does it kick on?

Hi Pretchel

NOPE... blower should not run all the time.

The blower should run when the water heater turns on to heat water and it should shut off shortly after that.

For example... a shower. The first few minutes you may not hear the blower turn on, but after some time the water heater senses that the water temperature is getting lower and it will turn the blower fan on and remove the combustion byproducts from heater ignition to the outside.

After the shower the blower may continue to blow for some time until the water heater is up to temperature again.

Now, if filling a hot tub, then blower would stay on even longer AFTER the tub is finished filling because it needs to recover (heat) a greater amount of water... so might seem that blower runs all the time.

BUT if blower does not shut off... then there is another problem. Get back to us and let us know what you think... Mark
