GFCI not required for the timer.I am just looking for any recommendations on which brand/model mechanical timer would be best to use for my heater. I bought a Utilitech from Lowes and also a Defiant from Home Depot, both in house brands, but thinking there may be better out there. I know I need a 20 amp timer and I am also going to install a GFCI before the timer because it is near a bathroom sink. I know there are lot's of brands out there. I looked at Amazon and they have several and reading the reviews I am a bit hesitant. Any recommendations for a 0-30, or a 0-60 minute timer?
