Frequently Asked Questions

Does my monthly price ever go up?

Our pricing isn’t a flashy promotional rate - it’s fair and transparent from the start. At Go Lime, we cap any price increases at 3.99% + CPI, so you'll never be caught off guard. No surprises, just straightforward savings. Plus, you can purchase the equipment at any time, giving you ultimate savings and flexibility.

What happens if I move?

Moving? No problem. Our Go Flex plan is fully transferable to the next homeowner, allowing them to seamlessly pick up where you left off. Just let us know 30 days before your move, and we’ll handle the rest. We’re here to make your move hassle-free, just the way it should be.

How much space does a tankless water heater actually save?

A standard tank water heater stands about 60 inches tall and 24 inches wide - taking up 10-16 square feet of your basement or utility room. The tankless unit mounts on your wall at just 26 x 14 inches and uses zero floor space.



Will a tankless heater fit where my old tank was?

Yes, because the unit mounts on the wall. Our installation team needs only the wall space, existing gas line, and a nearby vent point. The floor space your old tank occupied becomes completely yours.

What happens to my old tank?

We’ve got it covered. We’ll take care of draining, disconnecting, and removing your old tank, even returning it to your previous supplier. If you’re still under contract, you’ll be responsible for any fees or buyouts from your current provider. You won’t have to lift a finger (except maybe to wave goodbye to the hassle).

What is the warranty with my purchase?

With the Go Flex Program, you’re 100% covered—24/7/365—for both parts and labour, including annual maintenance. If you choose to purchase the equipment, you’ll receive the standard manufacturer’s warranty. Start with the Go Flex Program to enjoy all the benefits we offer, and when you’re ready, you can purchase the equipment at your convenience.

Is Go Flex a rental, and what is the term?

Go Flex isn’t a never-ending rental contract. It’s a game-changer: an industry-first flexible 180-month subscription with an anytime purchase option. Here’s how it works: 50% of your monthly payment reduces your purchase price, while the other 50% covers 24/7 service, annual maintenance, and unlimited parts and labour coverage. You get all the perks of ownership without the headaches—and the flexibility to purchase the equipment at any time.

What is the process for returning my old Water Heater to my existing provider?

For your convenience, we ensure that your old water heater is returned to the existing provider within 30 calendar days. Our team handles the process efficiently, so you don’t have to worry about a thing. If you have any questions or need further assistance, we're always here to help.

More than 18,000 homeowners in Ontario trust Go Lime with their hot water needs. We deliver choice, transparent buyouts, and best price in Ontario.
