Hi everyone, I'm new to the forums. There are some great info on here so I thought I'd finally create an account. 
I have a question for you guys.
[edit: I am replacing a 30 gallon electric water heater that's on its last legs with a 50 gallon natural gas one and I want to create more space on the first and second floor.]
Is it is better to have my gas furnace and water heater (both are natural draft) have their own power vent/flue or can they share one provided that i get the correct control kits and ensure the power vent and flue are capable of handling the combined BTU output? I live in Massachusetts by the way. Your feedback would be greatly appreciated!
I'm looking at getting one Tjernlund HS1 power vent (includes UC1 control board), a WHKE millivolt interlock kit for water heater, and a MAC1E multiple appliance interlock kit. This will supposedly let me vent both the furnace and water heater with one power vent and flue.
