HAVE LAARS LITE TELDYNE GAS HEATER. GAS CO TECO WAS HERE AND SAID I HAVE A GAS LEAK EMANATING FRON POOL HEATER. THEY SAID NOT DANGEROUS BUT COSTLY IN GAS USAGE HEATER WORKS OK. WHAT SHOULD I DO? mack

I would want to locate exactly where the leak was coming from and approximate cost for repairs.If you have some gas bills to compare current costs to prior costs and then a estimate to repair you can deceide if the cost to repair offsets the price for wasted gas.
As far as I'm concerned any gas leak that is bad enough to have a large impact on gas bill is bad enough to need fixed.I would recommend that you have a qualified service tech check the unit over and locate leak and estimate cost to repair. I don't have a lot of faith in most gas companies service men and most of their guesses on the severity of a leak are just that
I hope this helps you some.Unless it is a very small leak I would have it fixed. Thank you
