i have 4 infratech infrared heaters built into my outdoor living area. It was already in the home when i bought it last year. The heaters are turned on/off via 4 separate switches. This is the product that turns them on or off.
Infratech - 14 4305 - Accessory - Dual Duplex Switch Wall Plate and Gang Box 20 Amp Per Pole
I'm pretty sure that each heater is 1500 watt (so about 14A of power per circuit).
I'm pretty sure these are the heaters that are built in: Infratech - C15 - Single Element - 1,500 Watt Elecrtic Patio Heater - C Series
From what i understand these are purely resistive loads.
I have two questions, is there any zwave product i can buy that can handle the load and that can either work with the existing switches, or replacing them? Note that there are two switches in a single gang box.
Bonus question... Is there any way i can make the temperature variable? I would speculate that a purely resistive load would work well with a zwave switch that has a PWM in it (i'm actually not sure how the dimmers work in zwave dimmers, i assume its PWM). If its PWM is there any 20A dimmers out there that can fit my use case (especially fitting two dimming circuits in a single gang box).
if i wanted to do something hackerish i could do something with arduino and a SSR at the wiring closet where the heaters fuses are, but i would prefer to buy an already made product if one exist.
