Tankless Water Heater Repair Burnaby
Introduction to Tankless Water Heater Repair
Common Installation Issues We Fix
Tankless water heaters are a reliable and efficient solution for residential homes, but they can face occasional problems. At A2B Plumbing and Heating, we resolve the most common issues to ensure your system operates smoothly.
No Hot Water
A lack of hot water is one of the most disruptive issues and is often caused by insufficient gas or power supply, ignition failure, or clogged filters.
Inconsistent Water Temperatures
Fluctuating temperatures are usually caused by mineral buildup, faulty sensors, or system overload. These inconsistencies can make showers uncomfortable and daily tasks inefficient.
Sudden Bursts of Cold Water
Sometimes, you might experience a sudden burst of cold water while using hot water, particularly if the water flow stops and starts intermittently. This is a common quirk with tankless systems that can disrupt your comfort.
Delayed Hot Water
In larger homes or when the unit is located far from faucets, delayed hot water can be frustrating.
Low Water Pressure or Flow
Clogged filters or restricted plumbing can result in weak water flow, making household tasks inefficient.
Leaks
Leaks stem from loose connections, damaged seals, or internal corrosion. Even minor leaks can lead to significant water damage if not addressed promptly.

Tankless Water Heater Maintenance Services in Burnaby
Annual Flushing/Descaling
Over time, minerals like calcium and magnesium can build up inside your tankless water heater, particularly if you have hard water. Annual flushing and descaling remove these deposits, ensuring efficient operation and preventing damage to internal components.
Filter Replacement
The water inlet filter in your tankless water heater plays a crucial role in preventing debris and sediment from entering the system. Regular Replacement or cleaning of this filter is essential to maintain water flow and protect your unit from blockages.

We're here for you day or night, ready to tackle plumbing emergencies whenever they arise.
Sensor & Burner Cleaning
Sensors and burners can accumulate dust and grime, impairing your water heater's performance. Routine cleaning of these parts ensures accurate temperature readings and efficient combustion, reducing energy waste and extending the lifespan of the system.
Tankless Water Heater Repair vs. Replacement
When Repair Makes Sense
When Replacement Is the Better Option
Replacement becomes the better choice when your tankless water heater is nearing the end of its lifespan, typically around 15 to 20 years, or if it requires frequent and costly repairs. Additionally, if your unit can no longer meet your household’s hot water demands or its energy efficiency has significantly declined, upgrading to a newer, more advanced model may be more practical. Factors like rusting, corrosion, and irreparable internal damage also indicate it’s time for a replacement.
When Replacement Is the Better Option
The cost of repairing a tankless water heater depends on the nature of the problem and the parts required, often ranging from $150 to $750. On the other hand, replacing a tankless water heater can cost between $2,500 and $4,500, depending on the model and the complexity of the installation. While repairs are less expensive upfront, Replacement may provide better value in the long run, especially with modern, energy-efficient units that can reduce utility bills and offer advanced features.
