Just got a new Infinity system installed with UV lights (2 of them). Installer said that the UV lights stay on 24/7/365, which seems like a waste to me, especially when the system isn't running at all at night. Was thinking of putting them on a timer that they shut off from midnight to 6am, when the fan most likely will never run (or even if it does, wouldn't run much), to save electricity. I know it isn't much, but adds up to probably about an additional $25 / year in electricity we could save (yep, running those lights costs nearly a quarter / day at our current power rates, so over $80 / year if they are left on all the time).
The installer didn't think it was a good idea to switch them on and off; they might burn out quicker. Other florescent lights aren't like that - the ballast might burn out quicker, but the life of those is really long anyways. Is there any reason that I should not put the UV lights on a timer?
