20 Most Recent Teledyne Laars Laars Lite 2 Pool Heater 250,000 Btu / Natural Gas Questions & Answers


I am experiencing the same thing. My neighbor has a 400,000BTU Hayward heater that's on a timer and everyday I hear it kick-on and in the evenings as well. The humming is inescapable in my unit.
Unfortunately, I'm going to have to move. I cannot stand it. Fortunately, I'm renting and this hastened my search for a home purchase. I talked to the neighbor's pool tech "The Pool Doctor" and he confirmed that the noise is something that you have to live with as he said that he was not allowed to reduce the pressure of the heater, which might reduce the humming and noise.

first of all millivolt heaters dont have an actual flame sensor. flame rods are located in the electronic ignition models. The only "flame sensor" millivolt units have are the pilot generator or thermal pile. it also works as a safety, no pilot flame = no dc current, heater wont run
