When it’s time to install a new water heater, one of the first questions homeowners ask is, “How long will it take?” After all, no one wants to be without hot water for too long. The answer depends on several factors, including the type of water heater, the complexity of the installation, and whether it’s a replacement or a brand-new setup.
Average Time for Water Heater Installation
- Traditional Tank Water Heater Replacement:2-4 hours
- If you’re replacing an existing unit with a similar model, the process is fairly straightforward.
- Disconnecting the old unit, securing the new one, and testing the system are the primary steps.
- Tankless Water Heater Installation:4-10 hours
- Since tankless models require new venting, gas line adjustments, and sometimes electrical upgrades, they will take longer to install.
- First-Time Water Heater Installation:6-10 hours
- If your home has never had a water heater or you’re switching types (e.g., from tank to tankless), expect a longer installation due to necessary plumbing and electrical work.
Factors That Can Affect Installation Time
While the above timelines provide a general idea, several factors can speed up or slow down the process:
Type of Heater: Tankless water heaters require more setup than traditional tank models.
Location of Installation: Easy-to-access spaces make for quicker installs. Tight or unusual spaces require more work.
Permits & Inspections: Some areas require permits before work can begin, which may add extra time.
Existing Plumbing & Electrical Setup: If your system needs updates, it will take longer to complete the job.
Unexpected Issues: Corroded pipes, faulty wiring, or ventilation issues can add time to the process.
What to Expect During Installation
- Shutting Off Utilities: Water, gas, or electricity will be temporarily turned off.
- Draining & Removing the Old Unit: For replacements, the old water heater is drained and disconnected.
- Setting Up the New Water Heater: This includes mounting (for tankless systems), connecting water and gas lines, and securing venting.
- Testing & Safety Checks: The installer ensures there are no leaks and that everything functions correctly.
- Cleanup & Final Instructions: The team will clean up the area and provide instructions on maintenance and use.
How to Prepare for a Smooth Installation
Want to make sure the process goes as quickly and smoothly as possible? Here’s what you can do:
Clear the Area: Remove any clutter around your current water heater.
Confirm Permits: If your location requires permits, check that they’re in place before the installation date.
Know Your Options: Decide on the type of water heater you want before scheduling service.
Ask About Upgrades: If you’re interested in energy-efficient models or need extra features, discuss these with your installer in advance.
Choosing the Right Professional for the Job
