Tools & Methods We Use

Tank Water Heaters

Traditional storage tanks (40–75 gallon) provide a reliable reservoir of hot water. Ideal for households with consistent, predictable demand.

Tankless Water Heaters

On-demand units heat water as it flows through the unit, delivering endless hot water and up to 30% energy savings compared to conventional tanks.

Power-Vent Systems

Power-vent models use a fan-assisted exhaust, allowing flexible venting through a sidewall — perfect when vertical chimney venting isn't possible.

Expansion Tanks

Thermal expansion tanks protect your plumbing system from pressure spikes when heated water expands, extending the life of your water heater and fixtures.

Frequently Asked Questions

How long does a water heater last?
A traditional tank water heater lasts 8 to 12 years, while a tankless unit can last 15 to 20 years with proper maintenance. If your tank is over 10 years old and showing signs like rusty water, strange noises, or reduced hot water, it's time to plan a replacement before it fails completely.
Tank vs tankless water heater: which is better?
Tank heaters cost less upfront ($1,500 to $2,200 installed) and work well for predictable demand. Tankless units cost more ($3,500 to $6,500 installed) but deliver endless hot water, save up to 30% on energy, and last nearly twice as long. The best choice depends on your household size and hot water usage patterns.
What size water heater do I need?
A household of 1 to 2 people typically needs a 40-gallon tank or a 140,000 BTU tankless unit. Families of 3 to 4 need a 50 to 60-gallon tank or a 180,000 BTU tankless unit. Larger households may need a 75-gallon tank or a 199,000 BTU unit. ProFlow sizes your system based on actual peak demand during a free in-home assessment.
Why is my hot water rusty or discoloured?
Rusty hot water usually means the anode rod inside your tank has corroded and the tank itself is starting to rust. This is a sign the unit is nearing end-of-life. A plumber can replace the anode rod to extend the tank's life, but if the tank body is corroded, replacement is the safer option.
How much does it cost to replace a water heater in Toronto?
A standard 50-gallon tank water heater replacement in the GTA runs $1,500 to $2,200, including removal of the old unit, installation, and permits. Tankless installations start around $3,500. ProFlow provides detailed written quotes with no hidden fees — contact us for a free estimate.
Should I repair or replace my water heater?
If your water heater is under 6 years old and the repair costs less than half of a replacement, repair usually makes sense. For units over 8 years old, or those needing repeated repairs, replacement is more cost-effective. ProFlow will give you an honest recommendation based on your unit's age and condition.
Do water heaters need annual maintenance?
Yes. Flushing the tank to remove sediment, checking the anode rod, and testing the pressure relief valve once a year can extend your water heater's life by 3 to 5 years. Most homeowners skip this, which is why tanks often fail early. ProFlow offers annual maintenance plans starting at $99.
What are the signs my water heater is failing?
Warning signs include lukewarm water that used to be hot, rusty or metallic-tasting water, rumbling or popping noises from the tank, visible leaking around the base, and rising energy bills. If you notice any of these, schedule an inspection before the unit fails completely.
Are there rebates for water heater installation in Ontario?
Yes. Enbridge Gas offers rebates of up to $1,000 for qualifying high-efficiency water heaters, including tankless models. Some GTA municipalities also run additional incentive programs. ProFlow helps you identify available rebates and provides the documentation you need to apply.
Should I switch to a tankless water heater?
Tankless water heaters offer continuous hot water, lower energy bills (up to 30% savings), and a longer lifespan. They're ideal for larger families or homes with high hot water demand. We'll assess your home's needs and help you decide if tankless is right for you.
How long does installation take?
A standard tank water heater replacement takes 2 to 4 hours. Switching from tank to tankless may take a full day due to additional venting and gas line work. We'll provide a timeline during your free assessment.
Do you handle the permits?
Yes! We handle all necessary permits and arrange for required inspections. All our installations meet or exceed Ontario building codes, so you can be confident your new water heater is installed safely and legally.
How much does it cost to replace a hot water tank?
The cost to replace a hot water tank depends on the type and size of unit. A standard 50-gallon tank replacement typically ranges from $1,500 to $2,200, including removal of the old unit, installation, and permits. Tankless conversions start around $2,800. We provide a detailed written quote before any work begins so there are no surprises.
How much does a plumber cost in Toronto?
Most GTA plumbers charge between $100 and $200 per hour, plus materials. A typical service call runs $150 to $350 depending on the job. ProFlow provides free written estimates before any work starts, so you always know the cost upfront.
Do I need a licensed plumber in Ontario?
Yes. Ontario law requires anyone performing plumbing work to hold a valid licence regulated by the Technical Standards and Safety Authority (TSSA). Unlicensed work can void your home insurance and create safety hazards. Every ProFlow technician is fully licensed and insured.
