Explore the guide
Part 1 / 3
Equipment type and capacity
Identify the existing water heater's fuel type, capacity, installation location, and approximate age before comparing replacement quotes. Ask whether the estimate includes removal, code-required upgrades, venting, electrical or gas work, permits, and disposal. Never attempt gas or electrical modifications without qualified help.
Quote checklist: safely readable model label, current installation photos, access restrictions, and available service records. Do not open covers or disturb connections to collect information.
Part 2 / 3
Installation and code requirements
Ask the installer which existing conditions require further evaluation before quoting. Request that proposed upgrades, permits, and any electrical, gas, or venting work be identified separately.
Confirm whether the proposed capacity and equipment type fit the household needs discussed during the assessment.
Part 3 / 3
Removal and disposal
Ask whether removal, transport, disposal, cleanup, and restoration of affected finishes are included. Record exclusions and the approval process for additional work.
Have qualified professionals handle disconnection, gas or electrical work, relief components, and draining hot water. Ask how the completed installation will be checked and what warranty paperwork you will receive.
When to call a professional
Stop if you notice a safety hazard, water near energized equipment, signs of combustion or gas problems, or anything requiring a licensed trade. Do not attempt repairs beyond your training. Manufacturer instructions and local requirements take priority.
