Will this work for my keggle Reliance 2,000 Watt 120 Volt Electric Water Heater Element | Wayfair? Should I use two of them? Im trying to set up an electric BK so I dont have to brew outside. right now its only 5 gallon batches but I want to move up to 10 gallon. The problem I have is that I rent my house and it doesnt have any 220 lines. Any suggestions would be appreciated. Thanks
