Learn the warning signs your tankless water heater needs maintenance or repair. Project Heating explains temperature changes, low flow, and hard water issues in Alberta.
An on-demand or tankless water heater is one of the most efficient ways to provide hot water in Alberta homes. These systems heat water instantly and save energy, but they still require regular upkeep to stay in peak condition. Project Heating helps homeowners maintain their water heaters through professional cleaning, inspections, and repairs that extend lifespan and prevent costly breakdowns. You can learn more about our full range of heating services on the Project Heating website.
Regular maintenance keeps your tankless system running efficiently and safely. Over time, mineral buildup, sensor wear, or airflow blockages can reduce performance and cause inconsistent heating. Annual maintenance includes descaling, filter cleaning, and diagnostic checks to prevent long-term damage.
Routine service not only maintains energy efficiency but also prevents small issues from turning into expensive repairs. Homeowners who schedule maintenance once a year typically enjoy faster water heating, lower utility bills, and longer equipment life.
Knowing when to call a professional can prevent sudden system failure. Watch for these clear tankless water heater repair signs:
If you notice any of these issues, it’s important to schedule on-demand water heater maintenance before they worsen.
Most performance problems trace back to scale buildup from Alberta’s hard water, which restricts flow and forces the system to overwork. Hard water in the province typically contains high levels of calcium and magnesium, which settle inside the heat exchanger and create a layer of mineral scale. This buildup not only slows water flow but also traps heat, causing internal components to overheat and wear out faster.
Installing a water softener or filtration system can significantly reduce mineral deposits and extend your heater’s lifespan. Project Heating recommends pairing a tankless water heater with softening or descaling solutions to keep your system clean, efficient, and operating at full capacity year-round.
Other causes include blocked filters, improper venting, or aging components. Project Heating uses specialized tools and manufacturer-approved cleaning agents to remove scale and restore full function. Our technicians also check sensors, valves, and exhaust systems to ensure everything operates safely and efficiently.
Ignoring small warning signs can lead to higher energy bills and shorter system lifespan. A clogged or scaled-up heater must work harder to reach target temperatures, consuming more power and increasing mechanical stress. Delayed maintenance also raises the risk of leaks or part failure, which may require complete replacement.
Consistent servicing helps preserve performance and protect your investment. Project Heating’s water heater repair experts can quickly diagnose and correct issues before they impact long-term reliability.
Routine care ensures your water heater runs as efficiently as the day it was installed. Professional maintenance typically involves:
