Understanding tankless heaters

Tankless water heaters heat water on demand (rather than storing it in a tank). A flow sensor detects when you turn on a tap, triggering a gas burner or electric element to warm water as it passes through a compact heat exchanger. Because they lack a storage tank, these units can last 20 to 25 years—roughly double the life of traditional models—when maintained properly.

According to Natural Resources Canada’s guide to residential water heaters, water heating can account for a significant share of home energy use, so keeping your system efficient really pays off.

Like many Alberta communities, Sherwood Park’s water tends to be hard, so mineral scale can accumulate in the heat exchanger and flow sensor. Flushing your unit every six months helps prevent buildup, maintains energy efficiency, and avoids clogs in water lines.

Manufacturers such as A. O. Smith recommend regular descaling and filter checks as part of a standard water heater maintenance checklist, which lines up with the schedule we suggest here.

Identifying warning signs

Keeping an eye on these common symptoms can help you catch small issues before they become big headaches:

• Hot water shortage: You run out of hot water sooner than usual.
• Fluctuating temperature: Water swings from scalding to chilly mid-shower.
• Low flow rate: Reduced water pressure from hot taps (while cold pressure remains normal) may point to scale in the system (Parker Oil Company).
• Error codes: Modern units display codes for ignition failure, sensor faults, high temperature, or low flow.
• Leaks or drips: Even a small puddle around fittings suggests corrosion or a failing pressure relief valve.
• Higher energy bills: A buildup of scale forces the heater to work harder and longer, hiking up costs.

If you notice any of these signs, it’s time to move on to a few straightforward troubleshooting steps.

Performing simple fixes

Checking power and gas supply

1. Confirm the breaker is on or the fuse isn’t tripped.
2. Verify the gas shutoff valve is fully open (if you smell gas, turn off the valve, leave the area, and call your gas provider).
3. Inspect venting for blockages (birds’ nests or leaves can interrupt proper combustion).

Resetting your unit

1. Locate the reset button (often behind a small panel or on the control board).
2. Press and hold for 5 seconds, then release.
3. Wait a minute for the system to reboot. If error codes clear, run hot water to ensure steady flow.

Flushing scale

1. Turn off power and gas to the heater.
2. Close inlet and outlet valves.
3. Attach hoses to the service ports and connect to a submersible pump in a bucket of white vinegar or commercial descaler.
4. Circulate for 30–60 minutes, then flush with clean water.
5. Reopen valves, restore power and gas, and check for leaks.
