Four reasons Ontario homeowners are switching from tank to tankless.
If you've ever run out of hot water mid-shower, you already know one of them. The other three matter just as much over the next 20 years.
Endless hot water
Tankless heats on demand. Two showers, dishwasher, laundry — all at once, without anyone running cold.
Lasts twice as long
Tankless lifespan ~20 years. Standard tanks 8–12. You're not replacing a unit every decade.
Wall-mounted, compact
About the size of a carry-on suitcase. Frees up the floor space your old tank was hogging in the basement.
Lower gas use
Heats only when you turn on the tap. Standard tanks heat 24/7 even when you're not home.
🔎 Tankless vs Tank
The honest comparison. Specs over marketing.
Tankless isn't always right for every home. Here's the side-by-side, including where tank still wins.

Go Flex vs Traditional Rentals
If you're researching tankless, you're looking at a few paths. Here's how Go Flex compares — including where the others are a better fit.
| Traditional Rental |
|
|
|---|---|---|
| Where your money goes |
🔴
Pure rental fee. Pays for nothing you keep.
|
✅
50% builds your equity. 50% covers full service.
|
| What you own at the end |
🔴
Nothing. Equipment goes back. Or buy it for whatever they decide.
|
✅
Nothing. Equipment goes back. Or buy it for whatever they decide.
|
| The buyout number |
🔴
Calculated when you ask. Often more than the equipment is worth.
|
✅
Locked. In writing. On page one of your contract.
|
| If something breaks |
🔴
Read the policy. Sometimes covered, sometimes a service fee.
|
✅
Always covered. Bumper to bumper. Replacement included.
|
| If you want to leave |
🔴
Penalty fees. Removal fees. Plus the surprise buyout.
|
✅
Pay the buyout from your contract. Or transfer to next homeowner. Done.
|
| What you signed up for |
🔴
5, 10, even 15-year contract. Hard to remember the terms.
|
✅
One page. Plain English. No tricks.
|
| The fine print |
🔴
Pages of it. That's where the buyout math hides.
|
✅
There is no fine print. The whole deal fits on one page.

We needed to replace our furnace and water tank, and went with GoLime. They scheduled us pretty quickly and what a difference! Our water heats up no problem and lasts, the house heats up quickly, and the new duct work Travis installed has improved heating and cooling to an otherwise hard to heat/cool room.
Hernando Pineda
Mehdi - Came on time and installed my new furnace. He was very courteous and polite. He made sure to addressed all my concerns that I had with the old furnace. He left the area clean when he was done with all the work.
Brenda M
Perfect installation. Mehdi was here on time walked me through all the new equipment and was incredibly professional. Both our heat pump and tankless water heater are a vast improvement from our old 40L 16 year old tank and 27 year old AC compressor unit. So happy to go with Go Lime and would definitely recommend Mehdi for any installation of your equipment!
HARRY WOELK
A tankless water heater is the way to go.GoLime will send the best-informed installers. The unit was larger than expected, but it performs beautifully. producing endless hot water.
