On a gas tank, usually a pilot or igniter that has gone out, a failed thermocouple or gas control valve, or a tripped safety. If the tank is also leaking, repair is usually off the table and replacement is the answer.
Commonly sediment build-up on the tank floor, which eats into the volume you can actually heat, or a failing dip tube mixing cold water into the outlet. Both are diagnosable on a visit.
If the leak is at a fitting, a valve or the connections, often yes. If the tank itself has corroded through, no. A leaking tank only gets worse and should be replaced rather than patched.
Typically eight to twelve years, and longer where the water is soft and the anode rod has been replaced along the way. Past that point, spending money on repairs gets harder to justify.
We can install an owned unit in place of a rental, but the rental agreement is between you and the rental company, so check your buyout and return terms first. Our pricing list publishes installed prices for tank and tankless replacements.
A gas-fired one is, yes. Installation and venting fall under the Technical Standards and Safety Authority's rules in Ontario, the same as furnaces and boilers.
Gas work in Ontario is regulated. Every gas appliance we touch is handled to the standards set by the province’s safety regulator, and any certificate or licence we hold can be verified through them.
