Keeping Ottawa’s water hot for over 50 years
Rent-to-own or buy an electric, conventional, power-vent, direct-vent or tankless water heater. Standard installation is free, we take the old tank away, and if a rental ever breaks our own technicians fix it — parts and labour covered. Rentals are lease-to-own through our partner Vista Services, so every payment brings you closer to owning it.
What we do
Pick the job. We’ll tell you what you have, what you need, and one firm price.

One small monthly payment, free standard installation, repairs covered for the term — and you own it at the end. Lease-to-own with our partner Vista Services.
Rental prices
Own it outright with no monthly payments. John Wood, Giant, Rheem, GSW and more, installed by our own licensed technicians.
Tank types
Endless hot water from a box on the wall. We assess your gas line and venting first and give you the replacement details up front.
Tankless details
Vista rental? Book the dispatch with Vista and we come out. Own your tank? Call us direct. Most makes and models.
Repair details
Tired of the rate creep and the call centre? We handle the buyout or return and swap the tank without a gap in hot water.
How switching works
No gas on your street? Electric tanks for the city, propane and electric for the villages — rent or buy, same service.
Electric detailsHow it works
Tell us what the tank looks like and what it runs on. A person answers — if you get voicemail we’re on the other line and will call right back.
We confirm the type and size, then quote a monthly rental rate or a purchase price. No surprises on install day.
Licensed installers on our payroll, not subcontractors. Standard installation is free and takes two to three hours.
We take the old tank away and return it — to us, or to the company you rented it from — and keep the paperwork on file.
Why Mr. Rental Tank
Mr. Rental Tank is a division of Home Service Group Inc. at 36 Capital Drive in Nepean, working hand in hand with Reid Heating & Cooling and Renato’s Gas Piping. We’ve been installing and servicing hot water tanks in Ottawa for more than 50 years, and the people who answer the phone are the same people who send the truck.
John Wood, Giant, Rheem, GSW, Bosch — we’re not tied to one brand.
Most repairs are finished on the first visit because the part is already on board.
Authorized to do warranty work on most water heaters, rental or owned.
If a repair makes more sense than a new tank, that’s what we’ll tell you.
Our rental partner
Mr. Rental Tank is the Ottawa service partner for Vista Services, an Ottawa-based lease-to-own company — two separate companies that have worked side by side for 15 years. Vista owns the agreement and handles the monthly billing; we’re the crew Vista sends to install and service the tank. Unlike a traditional rental, every payment brings you closer to owning the equipment outright.
Installation is included in the agreement. One predictable monthly payment, pre-authorized from your bank account or credit card.
Repairs to the equipment are covered for the term of the agreement. Our own technicians do the work.
At the end of the term you buy the tank for a nominal, pre-set amount — or pay it off any time earlier. No renting forever.
Leaving another rental company? Vista acts as your agent and, if needed, indemnifies you against equipment removal charges.
Most agreements transfer to the buyer of your home, or you buy the tank out at closing. Vista’s team handles the paperwork.
You keep your relationship with us: an Ottawa crew from 36 Capital Drive, not a call centre in another province.
Vista Services
Vista Services is the lease-to-own company behind your rental agreement. For a service call on a rental tank, billing, payments, moving or anything to do with your account, call Vista’s 24/7 line 1-877-318-4782.
Mr. Rental Tank
We’re the local service partner Vista directs to install and service its equipment in Ottawa. Rental tank service is booked through Vista and dispatched to us; own your tank? call us direct at 613-233-1115.
Two separate companies — neither owns the other. Vista handles the agreement; Mr. Rental Tank handles the tank. Fifteen years of working together and being there for each other is why Vista trusts us with its customers, and why our customers get great service on both ends.
Questions
It depends on the type and size of tank — a 40-gallon electric is the least, a power-vent or tankless unit the most. Call us at 613-233-1115 and we'll give you today's monthly rate for the exact tank your house needs. Standard installation is free, we take the old tank away, repairs on rental units are covered, and because our rentals are lease-to-own through Vista Services, the tank is yours at the end of the term.
Your choice, always. Renting spreads the cost into a small monthly payment, covers parts and labour for the term, and — through our partner Vista Services — ends with you owning the tank. Buying costs more up front but there are no monthly payments, and it comes with the manufacturer's tank warranty plus our one-year labour warranty.
The tank is the same and the warranty is the same. Three things are different. First, the contract: the big providers typically lock you into a long initial term — 10 to 15 years is common on builder-installed tanks, and in some cases the agreement runs indefinitely — and getting out early usually means a buyout that can be worth years of payments, plus a pickup fee. Our agreements, through Vista Services, are a fixed 12-year term with the end date and a published buyout schedule on the contract, and the tank is yours at the end for a nominal amount. Not sure of your term? Ask — we never hide it, and you get it in writing when you sign. Second, the rate: ours is normally more competitive, and the annual adjustment is approximately 3.5% flat, printed on the agreement before you sign. The big providers tie theirs to inflation plus a margin — approximately the greater of 3.5% or Ontario CPI at one, approximately CPI plus 2% at the other (one confirmed up to about 3.9% for 2026) — so theirs can move more. All figures are approximate and can change; check the current agreement. Third, who shows up: our own technicians from 36 Capital Drive in Nepean, and a phone a person answers. We've been doing this in Ottawa for over 50 years.
Usually, yes. Call us with the name of the company and roughly how old the tank is. We'll tell you what the buyout or return looks like and handle the swap so you're never without hot water. Our partner Vista Services acts as your agent for the switch and, if needed, legally indemnifies you against removal charges from your old provider.
Have the venting checked once a year — the flue, the joints, the chimney connection and the draft at the hood. A blocked or leaking chimney vent lets carbon monoxide back into the house, and CO has no colour or smell. Ontario now requires a working CO alarm on every storey of a home with a gas water heater. If the chimney is in rough shape, a power-vent or direct-vent tank takes it out of the picture.
Ten to fifteen years is typical in Ottawa. Past fifteen you're living on borrowed time — the tank rusts from the inside and the first sign is usually water on the basement floor. One more thing people don't hear until it's too late: some home insurance companies want a tank that's ten years or older inspected or replaced, depending on the insurer and your policy, and a flooded basement from an old tank can be a hard claim. Have that conversation with your insurer before the tank forces it. If yours is that old, replace it on your schedule instead of on a Sunday night.
Monthly, by pre-authorized payment from your bank account or credit card, due on the 1st or the 15th, through our lease-to-own partner Vista Services. Vista owns the tank during the term; you can buy it out at any time, and at the end of the term you buy it for a nominal amount and it's yours. Our standard term is 12 years. Unsure of your term? Ask — we never hide it, and it's in writing when you sign.
Yes. A tankless unit needs enough gas supply and a vent to the outside. We assess both — some homes need a larger gas line, many don't — and give you the replacement details in writing before install day. It gives endless hot water and takes up almost no floor space.
Most agreements transfer to the new owner if they agree, or you can buy the tank out at closing. Disclose the rental in your listing and Vista Services will handle the transfer paperwork.
No. We work in Ontario only — Ottawa, Nepean, Kanata, Barrhaven, Orleans, Gloucester, Stittsville and the surrounding towns and villages.
We disconnect it, take it away on the same visit and return it for you. If it was a rental from another company we return it to them and keep the paperwork on file in case you ever need it.
