Markham Water Heater Install FAQs
How much does water heater installation cost in Markham?
A tank water heater installation in Markham typically runs $900 to $1,800 fully installed. A tankless gas water heater ranges from $1,800 to $3,500 depending on venting needs. Note: the legacy Enbridge HER+ tankless water-heater rebate closed Dec 31 2025. Heat-pump water heaters qualify for $500 through the Ontario Home Renovation Savings Program.
How long does water heater installation take in Markham?
Most tank replacements take 2 to 3 hours. Tankless installations take 3 to 5 hours. We dispatch same-day across Markham so you have hot water back the same day in most cases.
Are there water heater rebates in Markham in 2026?
The legacy Enbridge HER+ water-heater rebate closed Dec 31 2025. For 2026, the active rebate is the Ontario Home Renovation Savings Program (HRS), which pays $500 for a heat-pump water heater only (not for conventional gas tank or tankless units). EcoFrost handles the HRS application for qualifying installs.
Do you install water heaters across all Markham neighbourhoods?
Yes. We install across every Markham neighbourhood including Unionville, Cornell, Milliken, Cathedraltown, Berczy Village and surrounding areas. Markham covers heritage homes in Unionville with vertical flue venting and modern builds in Cornell and Cathedraltown that need power direct vent units. We size every install to the home.
Should I replace my water heater or just repair it?
If your water heater is over 10 years old and has a significant issue, replacement is almost always the better financial decision. Tanks under 8 years old are usually worth repairing. We give you an honest recommendation with flat-rate pricing on both options.
