Water Heater Types We Install & Repair

Every system heats water differently, so it fails differently too. We work on all of them, and help you choose the right one when it's time for a new water heater.

Most common

Gas tank water heater

A 40–60 gallon storage tank heated by a gas burner. Recovers quickly and works during power outages. Brands include Bradford White, GSW, Giant and A.O. Smith.

No gas line

Electric tank water heater

Heated by two elements instead of a burner. Simple to install where there's no gas, with fewer venting requirements. Rheem and Giant are common choices.

On-demand

Tankless water heater

Heats water only when you turn on a tap, so you never run out and there's no tank taking up space. Navien and Rinnai tankless water heaters are popular in Mississauga.

Heat + hot water

Combi boiler

One wall-mounted unit that heats your home and provides on-demand hot water. Ideal for homes with radiators or in-floor heating that want to drop a separate tank.

Water Heater Problems We Fix

Most water heater repair calls in Mississauga come down to one of these. Many are fixed in one visit; some are a sign the tank is near the end of its life.

No hot water

Failed thermocouple, gas valve, igniter, or a burnt-out element on electric units.

Hot water runs out fast

Sediment filling the tank, a broken dip tube or an undersized heater.

Hot water tank leaking

From a valve or fitting it's repairable. From the tank bottom, it needs replacing.

Pilot light out

Won't stay lit after relighting: thermocouple, draft or gas valve issue.

Error code or flashing light

Tankless and power-vent units report faults by code. We read and fix the cause.

Noise, rusty water or smell

Popping means sediment; rusty water or a rotten-egg smell points to the anode rod.

Emergency Water Heater Repair in Mississauga

A leaking hot water tank can release its full 40–60 gallons onto your floor, and no hot water with kids or older family members at home can't wait until Monday. Emergency water heater repair calls are answered 24/7. For any other urgent problem, see our 24/7 emergency plumbing.

Tank leaking? Do this now

  1. Shut off the cold water inlet. The valve is on the cold pipe at the top of the tank. Turn it clockwise.

  2. Turn off the heat source. Gas: set the control to "Off" or "Pilot". Electric: switch off the breaker.

  3. Contain the water. Move belongings away and use towels or a wet vac. Don't touch the T&P valve if water is very hot.

  4. Smell gas? Leave the house and call 911 and Enbridge Gas at 1-866-763-5427 from outside.

Repair or Replace Your Water Heater?

How long does a hot water tank last? The age of the unit is usually the deciding factor, along with what failed.

8–12 years

typical life of a tank water heater

Up to 20 years

typical life of a tankless water heater

Repair usually makes sense when

  • The tank is under about 8 years old
  • A part failed: thermocouple, element, gas valve, igniter
  • The leak is from a valve or fitting, not the tank
  • A tankless unit needs descaling or a sensor

Replacement usually makes sense when

  • The tank itself is leaking or rusted through
  • A tank is past 10–12 years and needs a major part
  • Rusty hot water keeps coming back
  • Your family regularly runs out of hot water

Water Heater Installation & Replacement

Whether it's a new water heater installation, a hot water tank replacement or a switch from tank to tankless, we size the unit to your household, not just the label on the old tank.

Hot water tank replacement

Old tank drained and removed, new one installed with proper venting, expansion tank and T&P discharge, often the same day.

Tank to tankless

Tankless water heater installation may need a larger gas line, new venting and a condensate drain. We check all three before quoting.

New units are covered by the manufacturer's warranty, and terms vary by brand and model. Most manufacturers require professional installation and regular maintenance to keep it valid, and we explain the terms for the unit you choose.

Rented Water Heater? You Have Options

Many Ontario homes have a rented hot water tank and pay a monthly fee for it, often for years after the tank has paid for itself. If your water heater is a rental, the rental company handles repairs on that unit, so check your agreement first.

If you'd rather own your system, we can install an owned tank or tankless water heater in place of the rental. Read your contract for any buyout or removal terms before you switch, and we'll help you compare the long-term cost.

Tankless water heater maintenance

Water Heater Maintenance

Regular maintenance helps a water heater reach the full end of its lifespan and keeps the manufacturer's warranty valid.

  • Tank flush to remove sediment that causes noise and short hot water
  • Anode rod check and replacement before the tank starts to rust
  • T&P valve test and venting inspection
  • Tankless descaling of the heat exchanger and inlet filter cleaning

Hard water speeds up scale. If it's an issue in your home, see our water softener service.

Commercial

Commercial Water Heater Service

Our hot water tank started leaking near the bottom. The plumber inspected it and explained why replacing the old tank was safer than trying to patch it. Professional service and no pressure.

Water Heater Questions from Mississauga Homeowners

Straight answers before you book water heater repair or installation.

Why do I have no hot water?

On a gas water heater, the most common causes are a pilot light that's gone out, a failed thermocouple or a faulty gas valve. On an electric unit, it's usually a tripped breaker, a burnt-out element or a bad thermostat. Tankless units often show an error code. If the basics check out, it needs a technician.

My hot water tank is leaking. Can it be repaired?

It depends where the water is coming from. Leaks from the T&P valve, drain valve or a pipe fitting can usually be repaired. If water is coming from the tank itself, usually the bottom, the tank has rusted through and needs replacing. Shut off the cold water inlet and the heat source, then call us.

How long does a hot water tank last?

A tank water heater typically lasts 8–12 years, while a tankless water heater can last up to 20 years with regular descaling. Hard water, skipped maintenance and a worn-out anode rod all shorten that life.

Is a tankless water heater worth it?

Tankless water heaters provide endless hot water, take up far less space and last longer than tanks. Installation costs more, especially if the gas line or venting needs upgrading. They're a strong choice for larger families or anyone tired of running out of hot water.

What is a combi boiler?

A combi boiler is a single unit that heats your home through radiators or in-floor heating and also supplies hot water on demand, so you don't need a separate water heater tank.

My water heater is a rental. Can I replace it with one I own?

Yes. Many Mississauga homeowners replace a rented hot water tank with an owned tank or tankless water heater. Check your rental agreement for buyout or removal terms first. While the unit is still rented, repairs are the rental company's responsibility.

What warranty comes with a new water heater?

New water heaters are covered by the manufacturer's warranty, and the terms depend on the brand and model. Most manufacturers require professional installation and regular maintenance to keep it valid, so keep your installation and service records.

Which water heater brands do you work on?

We repair and install Rheem, Bradford White, A.O. Smith, GSW, Giant, Navien and Rinnai water heaters, along with most other residential and commercial brands.

How often should a water heater be serviced?

Once a year. For a tank, that means flushing sediment, checking the anode rod and testing the T&P valve. Tankless water heaters need descaling and filter cleaning, more often if your water is hard.

Do you offer water heater repair near me in Mississauga?

Yes. We cover all of Mississauga, including Port Credit, Streetsville, Meadowvale, Erin Mills, Churchill Meadows and Cooksville, with same-day appointments and 24/7 response for leaks and no hot water. Call (289) 906-4166.
