Recepticle for water heater

[deep]

Can you please tell me where it is written in the code book that the water heater should be plugged in a dedicated recepticle in Ontario?

I asked tech support, he said its in ELECTRICAL CODE of Ontario.

Any reference of that please

Lots of good info here:

A gas water heater that supplies both domestic hot water and heating equipment shall be supplied by a branch circuit that does not supply any other outlets or by the same branch circuit that supplies the heating unit and associated equipment.


A gas water heater is not required to have a separate branch circuit for a power vent and ignition circuit and shall not be connected to the furnace circuit. The
receptacle for a gas water heater is permitted to be supplied by the required dedicated circuit for utility room receptacles or by any convenient general purpose receptacle/lighting circuit, if the water heater is not located in the utility room.

Always thought of it as a heating issue. If the house relies on a unit to heat itself, it should be on a dedicated line.
