Questions to ask before replacing a water heater
Replacing a water heater is a purchase you’ll live with for a decade or more, so asking the right questions up front pays off. The answers help you avoid an oversized unit, a bare-bones quote, or an unlicensed install.
A good contractor welcomes these questions and gives clear, honest answers rather than pushing the priciest option. Knowing what to ask puts you in control of the decision.
HeatLand has guided Metro Vancouver and Fraser Valley homeowners through water heater replacements since 1999. Below are the essential questions to ask, and why each one matters, before you commit.
Sizing and equipment questions
Start with what fits your home and household. Ask what size the technician recommends and why, based on your number of occupants and peak hot water use, an oversized unit wastes energy while an undersized one leaves you short. Ask whether a tank, tankless, or heat pump water heater makes sense for your situation, and what the trade-offs are in up-front cost, efficiency, and lifespan. Ask about fuel type: staying with gas or electric versus switching, and what infrastructure a switch would require. Ask which brands they service and stand behind, since parts availability and support matter over the unit’s life. A good installer explains the reasoning rather than just naming a model. HeatLand services all major brands and sizes each unit to your actual demand, so you get equipment matched to your home, not an upsell.
Quote, permits, and licensing questions
Get clarity on the full scope and who’s doing the work. Ask for an itemized quote and what it includes, a complete quote covers the unit, removal and disposal of the old one, fittings, seismic strapping, a drain pan where needed, venting or electrical connection, labour, and any permits. Ask what permits your job requires and whether the company handles them, since gas work in BC needs a permit and a licensed gas fitter. Confirm the company is licensed, insured, and, for gas, TSBC-certified, this protects you if anything goes wrong. Ask whether the price is firm or could change, and under what circumstances. These questions prevent surprise charges and unsafe, non-compliant work. HeatLand provides itemized quotes, is fully licensed, insured, and TSBC-certified, and handles all required permits so there are no hidden extras.
Warranty, timing, and maintenance questions
Finally, cover what happens after the install. Ask what the manufacturer warranty covers and for how long, and separately what labour warranty the installer offers, since these are different. Ask how long the job will take and whether you’ll have hot water the same day. Ask what maintenance the unit needs to stay efficient and reach its expected lifespan, tanks benefit from periodic flushing, and tankless units may need descaling in areas with harder water. Ask about financing if the cost is a concern, and whether any current rebates apply, but confirm rebate details through official programs rather than taking a figure at face value. These questions help you plan and protect your investment. HeatLand explains warranty coverage, offers financing, and shares maintenance guidance so your new water heater lasts and performs.

Frequently Asked Questions
What’s the most important question to ask before replacing a water heater?
Ask what size and type the technician recommends and why. Correct sizing based on your household prevents wasting energy on an oversized unit or running short with an undersized one. From there, confirm the quote is itemized and the installer is licensed and insured. These three points cover the biggest risks.
Should I ask about permits?
Yes. Gas water heater work in BC requires a permit and a licensed gas fitter, and other work may need permits depending on your municipality. Ask which permits your job requires and whether the company handles them. This ensures the install is inspected, compliant, and protects your insurance coverage.
How do I know if a quote is complete?
Ask for an itemized breakdown. A complete quote covers the unit, removal and disposal of the old one, fittings, seismic strapping, a drain pan where needed, venting or electrical work, labour, and permits. If a quote lists only the tank price, it’s likely missing necessary items that could appear as surprise charges later.
What should I ask about warranty?
Ask separately about the manufacturer warranty on the equipment and the labour warranty from the installer, as they differ in length and coverage. Understanding both tells you what’s protected if the unit fails or the install has an issue. HeatLand explains both so you know exactly what your coverage includes.
