Frequently Asked Questions About Water Heaters in Oshawa
How much does water heater replacement cost in Oshawa?
Water heater replacement in Oshawa costs $200-$2,500. A standard 50-gallon tank water heater runs $1,200–$2,200 installed. Tankless (on-demand) units cost $2,500–$4,500 including installation and any required gas line or venting upgrades.
Should I get a tank or tankless water heater?
For most Oshawa homes, a tank water heater is the most cost-effective choice. Tankless units cost more upfront but save 15–30% on energy bills long-term. They work well in newer Windfields and North Oshawa homes with existing gas lines.
How long does a water heater last?
A standard tank water heater lasts 8–12 years. Tankless units can last 15–20 years with annual maintenance. Oshawa's hard water can shorten lifespan — annual flushing helps extend it.
Do I need a permit for water heater installation in Oshawa?
Yes. Durham Region requires a plumbing permit for water heater installation or replacement. We handle the entire permit process as part of the job.
Can you repair my water heater instead of replacing it?
Often, yes. Common repairs like thermostat replacement ($150–$300), anode rod replacement ($100–$200), or element replacement ($150–$250) can extend your heater's life by years. We'll assess whether repair or replacement makes more financial sense.
