Tankless Water Heater Discount & Ontario Installer Directory
Some home insurance companies may offer a tankless water heater discount or favourable
rating consideration when an eligible tank-style water heater is replaced with a properly installed
tankless system. The discount is not automatic, and each insurer can set its own rules.
A tankless water heater can be a smart upgrade because it heats water on demand, may improve energy efficiency,
saves space, and removes one common water-damage concern: an aging storage tank full of water sitting in the basement.
Broker tip: before paying for the installation, ask your broker whether your insurer recognizes
tankless water heaters for a discount and what proof they need. Some insurers may request an invoice,
installation date, equipment details, photos, or confirmation that the old tank was removed.
Why insurers may care about tankless water heaters
Traditional tank-style water heaters hold a large volume of water and are connected to a pressurized supply line.
If the tank fails while you are at work, away for the weekend, or asleep, the water supply can continue feeding the leak
until someone shuts it off. That can turn a small failure into a major basement water loss.
A tank can look fine from the outside because the exterior shell is painted or powder coated.
The risk is often on the inside, where corrosion, sediment, age, water chemistry, and maintenance can matter.
Many tank-style water heaters are treated as serious replacement candidates around the 8 to 12 year range,
and many homeowners use 10 years as the point where they start planning replacement rather than waiting for a failure.
Tankless can reduce stored-water exposure
A tankless unit heats water on demand instead of storing a full tank of hot water.
Plumbing connections can still leak, but there is no aging storage tank holding dozens of gallons of water.
Energy efficiency can improve
ENERGY STAR notes that certified gas tankless water heaters heat water only when needed and can cut water heating expenses while providing continuous hot water.
Insurance discounts vary
Some insurers may offer a discount or rating benefit, while others may not.
Your broker can confirm whether your company recognizes the upgrade before you spend money.
Claims warning: home insurance is usually designed for sudden and accidental losses, not predictable
maintenance problems. If a water heater is past the insurer’s age requirement, has visible corrosion, has been ignored
after warning signs, or is subject to an exclusion, a related water claim may be denied or limited.
Check the age of your current water tank before it becomes an insurance problem
If you have a tank-style water heater, find the manufacturer label, serial number, installation paperwork,
rental contract, or service record. Do not assume the tank is safe because it still looks clean outside.
The inside can be aging while the outer shell still looks acceptable.
If your tank is older, ask your insurer or broker whether they have a maximum water heater age, special deductible,
exclusion, replacement requirement, inspection requirement, or discount for removing the storage tank.
Traditional storage tankLower upfront cost in many cases, but it stores water in a tank that can corrode or fail with age. The age, maintenance history, and insurer requirements matter.
Tankless water heaterHigher installation complexity in many homes, but it heats water on demand, saves space, avoids the large storage tank, and may be eligible for a discount with some insurers.
Before you installAsk about gas line sizing, venting, electrical, condensate drainage, water hardness, annual maintenance, descaling, flow rate, warranty, permits, and whether the installer is properly licensed for the work.

Questions to ask before installing a tankless water heater
Insurance questions
Does my insurer offer a tankless water heater discount? What proof is required? Is there a maximum age rule for my current tank? Will my water damage deductible or eligibility change?
Installation questions
Does the quote include gas line sizing, venting, condensate drainage, electrical work, permits, old tank removal, and bringing the installation up to current code?
Maintenance questions
Does the unit require annual flushing or descaling? Is your water hard? What maintenance records should you keep for warranty and insurance purposes?
Keep the paid invoice, installation date, model number, serial number, photos, and any permit or inspection documents.
Send the relevant proof to your broker so they can confirm whether the insurer can apply the discount.
Tankless water heater discount FAQs
Does a tankless water heater guarantee a home insurance discount?
No. Some insurers may offer a discount or rating benefit, but it depends on the insurer, the property,
the policy, the age of the old tank, and the proof of installation.
Why can an old water tank be a problem for insurance?
Older tanks have a higher chance of corrosion, leaks and failure. If a loss is connected to age, corrosion,
wear and tear, poor maintenance, or a specific water heater exclusion, coverage may be denied or limited.
Is tankless always better than a storage tank?
Not always. Tankless units can be efficient and reduce stored-water exposure, but installation can be more complex.
Your hot water demand, gas line, venting, water hardness, electrical setup, upfront cost, and maintenance needs all matter.
Should I call my broker before replacing my water heater?
Yes. Your broker can tell you whether your insurer offers a tankless water heater discount,
whether the current tank age is an underwriting concern, and what documentation to keep after installation.
