To cancel or buy out a rented water heater, get your agreement and ask the provider in writing for today's buyout figure, any removal or return charges and the notice process. A buyout makes the existing tank yours; cancelling usually means returning it once an owned heater is installed. Compare the exit cost with a purchase quote, and if you are selling the house, involve your lawyer early.
- The agreement, not a market rule, sets what leaving costs: read the buyout schedule, cancellation charges and return terms first.
- Buyout prices usually step down as the installed tank ages, and a replacement made under the rental can restart the schedule.
- Never let an installer scrap a rented tank; return it as the agreement requires and keep proof.
- When a house with a rental is sold, the purchase agreement must say who assumes, buys out or replaces it, and the lawyers settle it on closing.
- In Ontario, specific consumer rules cover water heater contracts, and Consumer Protection Ontario takes complaints the business will not resolve.
01 /What should you check in a water heater rental agreement?
Start with the paper, because every exit option depends on it. A rental agreement is a contract for equipment the provider still owns, and its schedules decide what you pay to leave. If you inherited the rental when you bought the house, you may never have signed anything yourself: ask the provider for the terms attached to your account, and look in your purchase documents for the clause that assigned the rental to you.
| Clause | What it controls | Ask for in writing |
|---|---|---|
| Start date and term | Whether you are inside a minimum term or month to month | The installation date of this tank and any fixed term still running |
| Monthly fee and increases | How fast the cost of staying grows | The current fee before tax and the rule for increases |
| What the fee covers | Repairs, parts, labour and replacement of a failed unit | Exclusions, such as venting, freezing damage or a tank someone else moved |
| Buyout schedule | The price to take ownership, usually by the tank's age | Today's buyout figure and the date it next changes |
| Cancellation or early termination | Charges for ending the contract before a set date | Every charge that applies if you cancel this month |
| Removal and return | Who disconnects and collects the tank, and fees for one not returned | The return method, the deadline and any charge |
| Transfer on sale | Whether a buyer can take over the account | The transfer form and what the provider needs from the buyer |
| Replacement under the rental | Whether a new tank restarts a term or a schedule | Whether any past replacement reset your schedule |
Ontario's consumer guidance suggests getting answers in writing on contract length, any security interest on your home, cancellation costs, automatic renewal, installation and removal fees, and responsibility for the equipment if you sell. It works as a checklist for any rental in Canada.
02 /How do buyout schedules work, and what sets the price?
A buyout schedule is a table in, or attached to, the agreement that prices ownership of the installed tank at each point in its life. The usual pattern starts high while the tank is new and steps down as it ages, sometimes to a small amount near the end. Schedules differ between providers, and between older and newer contracts from the same provider, so the only figure that counts is the one quoted for your account on a given date.
- Age of the installed tank. The clock usually runs from the day this particular tank went in, not the day your account opened. A tank replaced under the rental can put you back near the top of the schedule.
- Type of heater. Power-vent, condensing, tankless and heat pump units cost more new, and their schedules tend to start higher than a basic atmospheric or electric tank's.
- Balance on the account. Unpaid rent, late charges and taxes are normally added to the figure.
- Exit charges. Some agreements add an administration or removal charge even when you buy, so ask whether the quote is the full amount and when the price next steps down.
A cheap buyout is not automatically a bargain. A tank near the end of its schedule is often near the end of its life, and buying it moves every future repair onto you. Enter its age and your water conditions in the Tank Lifespan Predictor before paying to own an old tank.
| Option | What you pay | Usually suits |
|---|---|---|
| Keep renting | The monthly fee, rising as the agreement allows | A young tank, a high buyout, or a move within a few years |
| Buy out the existing tank | The quoted buyout, then your own repairs and upkeep | A mid-life tank of the right size with a modest buyout |
| Cancel, return and install your own | Any removal or return charge, plus a new heater installed: electric $1,400–$2,600, atmospheric gas $1,800–$3,200, power vent $3,000–$5,000 | An old tank, the wrong size or type, or a wish for a more efficient heater |
To compare them, enter your fee, its increase and a written quote in the Rent or Buy Calculator, adding any exit charge to the purchase side. The replacement cost guide explains installed prices.
03 /How do you cancel a rental and return the tank?
Cancelling usually means ending the rental on the day an owned heater replaces the rented one, then getting the old tank back to the provider in the way the agreement requires. The order matters, because a disconnected rental tank is still someone else's property.
- Ask for the exit terms in writing
Request the cancellation process, today's buyout, any removal or return charge and where notice must go. Note who you spoke to and when.
- Book the replacement
Tell each installer the old tank is rented, so they drain it, disconnect it cleanly and set it aside rather than hauling it away.
- Follow the return method
Depending on the agreement, the provider collects the tank, sends a return kit or label, or accepts a drop-off. Ask how long you have and what happens after that.
- Keep proof of return
Photograph the rating label with its serial number, note the date it was disconnected, and keep any pickup receipt or tracking number.
- Confirm the account is closed
Ask for a final statement showing the last charge and a zero balance, then check the next two bills in case charges continue.
If a rented tank is leaking, the order changes: make it safe, call the provider first because repairing or replacing the rented unit is usually theirs, and read water heater leaks and home insurance before you clean up any damage.
04 /What changes when an owned heater replaces a rented one?
Ownership moves three jobs to you: repairs, maintenance and the records that show the heater was installed properly. In return you choose the type, size and efficiency, which a rental replacement may not let you do. Before you pick a size, run your household's busiest morning through the Hot Water Morning Simulator to see whether a smaller or different heater would keep up.
| Item | Rented tank | Owned tank |
|---|---|---|
| Repairs and failed parts | Usually the provider, under the agreement | You, within the manufacturer's warranty |
| Choice of heater | The provider's range | Any certified heater that suits the house |
| Permit and inspection | Arranged by the provider's installer | Arranged by the installer you hire; ask who pulls it |
| Maintenance | Often included or offered | Flushing and anode checks are yours to schedule |
| Rebates | Often unavailable to renters | Some programs require the owner to buy |
| Age and install records | Held by the provider | Yours to keep for insurance and resale |
Hire someone whose credentials match the connections involved. A gas tank needs a gas-qualified installer working under a permit; who installs water heaters explains which trade does what in each province, and the installation guide lists what a complete job includes.
05 /What happens to a rented water heater when you sell or buy a house?
Because the tank belongs to the provider, the agreement of purchase and sale has to deal with it. There are three usual outcomes: the buyer assumes the rental, the seller buys it out before closing so an owned tank is included, or the seller replaces it with an owned heater. Which one applies is part of the negotiation, and your lawyer (a notary in Quebec) should see the rental terms before any conditions are waived.
- Sellers: gather the account number, the agreement, the installation date and today's buyout figure before listing.
- Buyers: ask for the same details, and if you plan to replace the tank soon, build the fee and buyout into your offer.
- Assumption and transfer: the provider usually needs the buyer's details and the closing date. Confirm who sends the transfer form and that the seller's billing stops on closing day.
- Closing adjustments: prepaid rent, arrears or an agreed buyout are settled through the lawyers on closing, so tell yours early.
- Title in Ontario: the Homeowner Protection Act banned consumer notices of security interest (NOSIs) from June 6, 2024 and deemed existing ones expired. An expired NOSI can still appear on title but does not affect the land, and a lawyer can apply to amend the register if a buyer or lender wants it gone.
06 /Why is the rental charged on a utility bill?
A water heater rental is an equipment contract, not an energy service, even when the fee appears on a gas or utility bill. Some providers bill through the utility and others invoice directly; either way the charge follows the rental agreement's own rules.
- Closing or moving your gas account does not end the rental; cancel or transfer it with the provider as well.
- If a bill line names a company you do not recognize, ask the utility who placed the charge, then ask that company for the contract.
- Keep a year of bills: they show the fee history for the calculator and any dispute.
07 /How do you dispute a rental charge or make a complaint?
Start with the provider, in writing. Give the account number, the charge you dispute, why, and what you want: a refund, a corrected buyout, or confirmation that the account is closed. Keep copies, dates and names.
Ontario has rules written for these contracts. According to the Government of Ontario, a business cannot offer or sell a water heater at your home unless you initiated the contact, and a contract that results from prohibited door-to-door marketing is void, so you may keep the goods or services without obligation. A contract signed at home can be cancelled for any reason within 10 days of receiving the written copy, and within one year if you never received a written contract, if it lacked required information, or if the business made a false or misleading statement. Even inside the 10 days, you may owe rental payments, removal costs and charges for unreasonable wear if you asked for installation before the period ended.
If the business does not fix the problem, the province asks you to tell the business about your complaint first and then file with Consumer Protection Ontario online, by email, by mail or by phone at 1-800-889-9768. The ministry may try to mediate, but it cannot take complaints more than two years old or pursue damages beyond a refund of money already paid. Outside Ontario, contact your province's consumer protection office. The Ontario guide and the Across Canada page cover the regional picture, and rental vs buy covers whether renting makes sense at all.
FAQQuestions people ask
How long are hot water tank rentals?
There is no standard length. Some agreements run month to month after a minimum term, and others restart a term or schedule when a tank is replaced. Your agreement and the installation date of the current tank tell you where you stand.
How do I transfer a hot water tank rental when I sell my house?
Put the rental in the agreement of purchase and sale, give the buyer the account details, and ask the provider for its transfer process. The account moves to the buyer on the closing date, and the lawyers confirm it.
Is water heater rental part of utilities?
No. The fee may appear on a gas or utility bill, but it pays for equipment under a separate contract. Ending the rental does not affect your energy supply, and closing a gas account does not end the rental.
Can I replace a rented hot water tank without telling the rental company?
You can hire an installer, but the old tank still belongs to the provider and the agreement keeps running. Cancel or buy out first and return the tank as required, or charges may continue.
What happens if I don't return a rented water heater?
Agreements commonly charge for an unreturned tank, and billing may continue until the return is recorded. Keep photos, the serial number and the pickup receipt.
Who do I complain to about a water heater rental company in Ontario?
Write to the company first. If that fails, file with Consumer Protection Ontario online or by phone at 1-800-889-9768. The ministry does not handle complaints more than two years old.
