About water heater installation
Water heaters give around eight to twelve years and then fail, often suddenly and occasionally messily. Replacing one is a licensed job: it involves gas or high-current electrical work, venting, pressure relief and, in most jurisdictions, a permit and an inspection. The decisions worth making before booking are tank versus tankless, and what capacity you actually need.
Replacing a conventional tank water heater typically runs $900 to $2,200 fitted, depending on capacity, fuel type and how much the existing installation has to change. Tankless conversion is a bigger job at roughly $2,500 to $5,500, because it usually needs new venting and often a gas line upgrade or a dedicated electrical circuit — the unit itself is only part of it. Permits and inspection are normally included in a licensed plumber's quote; ask, because an uninspected installation can be a problem when you sell. Signs yours is near the end: rusty water, rumbling from sediment, water around the base, or an age past ten years.

Questions about water heater installation
Is tankless worth the extra cost?
It depends on your usage. Tankless gives endless hot water and lower standing losses, and lasts longer, but the installation is materially more expensive because of venting and supply upgrades. On a household that runs out of hot water regularly it usually pays back; on a small, low-demand home it often does not.
How do I know mine is about to fail?
Rusty or discoloured hot water, rumbling or popping from sediment in the tank, longer recovery times, and any moisture around the base. A tank over ten years old showing any of these is worth replacing on your schedule rather than on its own.
Do I need a permit?
In most jurisdictions, yes — water heater replacement involves gas, venting or high-current electrical work and is inspected. A licensed plumber will normally handle the permit as part of the job. An unpermitted installation can complicate an insurance claim or a sale later.
