Question about power...

Some good advice here, but be careful, not all is necessarily according to code. Might be a good idea to go to your local renovation center and invest in a book called the "Electrical Code Simplified" for your province. I have the BC edition and it cost all of $11.95 but I consider that money wisely spent since I'm doing a fair amount of rewiring in my older home. I used to maintain electrical systems on aircraft, so I'm comfortable working on my house wiring.

"you might have your fridge on the same cct as your tank"... not legal according to code in BC. A fridge has to be on it's own circuit and the only other load that may be plugged into that receptacle is a "clock" of all things... I'm sure the Alberta code requirement is similar.

"just run a new dedicated 20A 12gauge line to the tank."... 20A circuits require special receptacles (T-Slot) and you're still working with only one circuit. If the breaker goes, everything is down. While a normal plug will fit into a T-Slot receptacle, you may be better off running a single 3 wire cable which will allow you to run two separate 15 amp circuits for a total load of 30 amps, vice 20. This will provide redundancy and you'll be able to use 14 guage wire instead of 12.

While you're still safe with the total of 1300 watts on that circuit, I'll wager that some of the wiring on it will be pretty warm at times. Better safe than sorry. As heat increases in wiring, resistance increases, causing more heat, more resistance.... hopefully the circuit breaker will do its job, but no need to push your luck when it comes to electrons. If you're thinking of adding another tank with it's equipment to that room, I don't think you have any choice but to run another circuit or two.
