Hot Water Tank Installation in London for Tank and Tankless Systems

Hy-Pro Plumbing and Drain Cleaning handles water heater replacement in London, from a straight gas tank swap to a full switch to tankless. We size the new unit to your household, haul the old tank away and test everything before we leave. You’ll see one flat-rate price for the whole job before work begins. Reach our London plumber team at 226-289-1773.

How Does Water Heater Installation in London Work?

Water heater replacement means taking out a tank that’s leaking or worn out and installing a new unit sized to your home, then piping, venting and testing it. Sizing comes first. A family of four with two full bathrooms pulls far more hot water at 7 a.m. than a couple in a condo, so we count people, bathrooms and big users like a soaker tub before recommending a tank size or tankless flow rate. Our plumbing crews work from the same sizing checklist.

London’s housing stock shapes the venting plan. In its 2011 count, Statistics Canada listed about 82,900 of the London area’s 195,000 dwellings as built before 1971, and many homes from that era vent the water heater up a masonry chimney. Swap the old furnace for a high-efficiency model that vents out the side wall, and the water heater ends up alone in a flue sized for two appliances. It can struggle to draft. We check the draft and, where needed, recommend a chimney liner or a power-vented tank.

Install day follows a set order. We shut off the gas or power and the cold water, drain the old tank and disconnect it. The new heater goes in level, with fresh water connections, a relief valve discharge pipe aimed toward the floor, and new gas or electrical hookups. In Ontario, gas appliance work falls under TSSA certification, and a G2 certificate holder can install a residential gas water heater without supervision. We fill the tank, bleed air from your lines, fire it up and confirm the venting draws.

Temperature is the final setting. The Middlesex-London Health Unit advises keeping stored hot water at 60°C to limit Legionella growth, with mixing valves set to deliver about 49°C at the tap to prevent scalds. We set the tank and adjust any mixing valve in the line before handing it over. Rental tanks are the exception on removal: the tank belongs to the rental company, so call them before install day to arrange its return.

Why Choose Hy-Pro for Your New Water Heater in London?

A new water heater lasts only as long as the install behind it, and our plumbers average about 10 years of experience doing this work across Southwestern Ontario. Hy-Pro Plumbing and Drain Cleaning has worked in the region for more than 25 years. We’re a family-owned, Canadian owned and operated company of about 50 people, with a London office on Wellington Street and our home base in Cambridge.

Pricing stays simple. You get one flat-rate quote for the full install, and it won’t climb if the job runs long. Financing through Financeit is available, subject to credit approval.

At Hy-Pro, we lay out the options before you choose. A like-for-like swap to the same size gas tank is usually the simplest route. Tankless, a power vent conversion or a bigger tank each add work, and we’ll show you where the extra cost goes. Fall is a good window to plan. A tank with rust at the fittings in October rarely looks better by February.

Frequently Asked Questions About Hot Water Tank Replacement in London

What does a water heater replacement cost in London?

The price depends on what goes in and what has to change around it. A like-for-like gas tank costs the least. Moving to tankless, upsizing, adding a power vent or running a larger gas line each add parts and labour. We quote a flat rate after seeing your setup, so the number covers the whole job. Read the size and fuel type off the old tank’s rating plate when you call, and we’ll arrive with matching options.

Should I rent or buy my water heater in Ontario?

It comes down to the numbers in your current contract. The Government of Ontario lists water heaters among the products a business can’t sell or rent door-to-door unless you invited them, and you get a 10-day cooling-off period once you receive a written contract. Ending an existing rental can carry buyout or removal fees, so ask your rental company for that figure in writing. Bought your London home with a rented tank? You might have taken over that contract at closing.

How do I know if my water heater needs replacing instead of repairing?

Water coming from the tank body itself is the clearest sign, because a failed steel liner can’t be patched. Rust at the seams, rusty hot water at every tap and a tank past its tenth year point the same way. A bad element or thermocouple on a younger tank is usually a repair. Check the date on the rating plate, or send us a photo of it.

Is a tankless water heater worth it in London?

For bigger households with steady demand, often yes, but your gas line decides a lot. Natural Resources Canada says an ENERGY STAR certified tankless heater saves 30% more energy than a standard storage tank. Winter is the catch in London. Water entering your home in January runs far colder than in August, so the unit has to be sized for the coldest month, and many homes need a larger gas line to feed it.

What other services can Hy-Pro handle in London?

Plenty beyond water heaters. Calls we take across the city include:

  • Water softener and water filter installation
  • Leak detection for hidden pipe leaks
  • Sump pump repair and backup pumps
  • Trenchless sewer line repair
  • Toilet replacement

A softener is worth pricing alongside a new tank, since it cuts the scale that settles on the tank floor.

How do I schedule water heater installation in London?

Call 226-289-1773 or fill out the Schedule Service form on this page. Share the age, size and fuel type of your current tank, plus any rental company name, and we’ll book a visit to size the replacement. Our London crews follow the same flat-rate process as our Cambridge team. Not sure the old tank is finished? Our guide to water heater repair in London walks through the common fixes first.
