Tankless Water Heater Maintenance in Little Italy, Toronto

Tankless water heaters last longer than traditional tanks, but they still need annual maintenance to perform at their best. The biggest enemy is scale buildup — mineral deposits from Toronto's hard water that reduce efficiency and can eventually damage internal components.

Why Tankless Maintenance Is Essential

Without regular maintenance, scale buildup inside the heat exchanger forces your unit to work harder, leading to:

• Reduced efficiency — higher gas bills as the unit struggles to heat through scale
• Error codes and shutdowns — the unit's safety systems trigger when it overheats
• Shortened lifespan — a neglected unit may last 10 years instead of 20+
• Costly repairs — heat exchanger replacement is expensive and often preventable
• Voided warranty — most manufacturers require annual maintenance

What's Included in a Tankless Tune-Up

• Full system descaling — we flush the heat exchanger with a descaling solution to remove mineral deposits
• Inlet filter cleaning — removing debris that restricts water flow
• Burner inspection — checking for clean, efficient combustion
• Venting inspection — ensuring exhaust is venting safely
• Error code history review — checking for recurring issues
• Gas pressure check — verifying proper gas supply
• Flow rate testing — confirming the unit delivers the right temperature at full flow
• Overall condition assessment — letting you know if any parts are showing wear

How Often Should You Service a Tankless Unit?

We recommend annual maintenance for all tankless water heaters. Toronto's water has moderate mineral content, which means scale builds up steadily over time. Annual descaling keeps your unit running like new.
