Water heater replacement
A failing water heater is disruptive, and the decision is often rushed. This page explains the common warning signs and what to ask so you can plan your replacement with confidence.
Signs it may be time to replace
It is past its recommended lifetime
Tank water heaters often last somewhere around 8 to 12 years, though this varies with the model, water quality and how heavily it is used. Check the date on the unit's label.
Leaks or puddles
Water around the base can mean the tank itself has failed, which usually means the unit has reached the end of its life.
Rusty or discolored hot water
Rust-colored hot water that is not coming from the cold side can point to corrosion inside the tank.
Not enough hot water, or uneven temperature
Running out sooner than before can be a sign of a failing element, sediment build-up or an aging tank.
Rumbling or popping sounds
Noises while heating are often caused by sediment on the bottom of the tank. Hard water makes this more common and can shorten the heater's life.
Before you replace
Like-for-like or a change
Replacing with the same type is usually the simplest. If you often run out of hot water, it is a good moment to size up or consider a different type.
Condition of connections
Older valves, pipes, venting or electrical connections may need updating to meet current requirements.
Timing
If you have no hot water, tell us how urgent it is when you request your quote so we can discuss availability.
Good questions to ask about your quote
Clear answers to these make it easy to know exactly what you are getting.
- Is a permit or inspection needed for this job, and who arranges it?
- Does the quote include removing and disposing of the old unit?
- What does the warranty cover, for parts and for labor, and for how long?
- Are any code-related extras expected, such as an expansion tank or updated venting?
- What is the estimated timeline from approval to finished work?
Common questions
What information helps you quote a water heater replacement?
The type of heater (tank or tankless), its fuel (electric, gas or propane), its approximate size and age, and where it is installed. A photo of the unit and its label helps.
Should I replace my water heater before it fails?
Replacing a heater that is old but still working is a judgement call. Planning ahead avoids a cold-shower emergency and a rushed decision, but there is no single right answer for every home.
