Is a 1500 W 110v element sufficient to maintain mash temperature? I'm only concerned will the ability to maintain the temp post dough-in. The tube body is 1 1/2" x 8" (not including the tees). I have a 10g system and do not plan to use it for step mashing. Assume a normal mash recirculating rate. I'm currently limited to 15a circuits and want to avoid installing a 20a breaker with new wiring if at all possible.
