Exploring the Basics: What is a Tankless Water Heater?
A tankless water heater is an innovative system designed to heat water directly without the need for a storage tank. Unlike traditional water heaters, which continuously heat a reservoir of water, tankless models only heat water as it is required. This not only leads to energy savings but also helps in reducing household energy consumption and costs. Additionally, tankless water heaters are valued for their compact design, making them ideal for homes with limited space.

Tankless Water Heater vs. Traditional Models: A Comparative Insight

When it comes to choosing a water heating system, understanding the differences between tankless water heaters and traditional storage heaters is essential.
Instant Heating: Tankless systems provide hot water instantly, unlike traditional models that take time to heat a full tank.
Environmental Impact: Tankless models use less energy, reducing your carbon footprint, while traditional heaters continuously consume energy to keep water hot.
Installation and Replacement Considerations: Tankless systems may have higher upfront costs and a more complex installation, but offer long-term savings. Storage water heaters are simpler to install and have lower initial costs.
Capacity and Flow Rate: Tankless heaters are ideal for small to medium households. Larger homes may require multiple units to meet high hot water demand, which can affect both cost and space requirements.
Note: Consider your household's specific hot water usage to determine the best choice – a tankless model can be more efficient, but ensure it meets your capacity needs.
Navigating the Market: Choosing the Best Tankless Water Heaters

When selecting the best tankless water heaters, understanding key features is essential to making an informed choice.
Prioritise Energy Efficiency: Focus on energy efficiency, which not only lowers your monthly energy bills but also contributes to environmental sustainability. Look for units with high energy ratings, especially those that meet Canadian efficiency standards.
Check the Flow Rate: The flow rate determines how much hot water the unit can provide at one time. This is key for larger households or homes with multiple bathrooms.
Review Installation Requirements: Some units may need upgrades to your home’s electrical system, gas lines, or ventilation. Be sure to factor in these potential extra costs.
Assess Durability and Longevity: A well-built unit can save you money over time. Choose models known for durability to minimise replacements and maintenance down the line.
Evaluate Warranty and Customer Support: Pick a brand that backs its products with a strong warranty and responsive customer service to ensure peace of mind post-installation.
Consider Your Home's Layout and Materials: The size of your space, installation complexity, and materials used can all impact your final choice. Make sure the unit fits your home’s unique setup.

Smart Tips for Efficient Tankless Water Heater Maintenance
Maintaining your tankless water heater efficiently is key to ensuring its longevity and performance. Regular maintenance not only keeps your system running smoothly but also prevents unexpected breakdowns.

Descale Regularly: Prevent hard water buildup by descaling your tankless water heater—especially important in areas with hard water. Aim to do this at least once a year.
-
Clean the Filters: Keep inlet screens and other filters clean to maintain optimal water flow and heater efficiency. Check and clean them regularly as part of your routine.
-
Schedule Professional Inspections: Have a licensed professional inspect your system annually or bi-annually to catch potential issues early and ensure everything is running smoothly.
Familiarising yourself with common issues—such as lack of hot water, fluctuating water temperatures, and error codes—and knowing how to troubleshoot can enhance your user experience.

Solving Common Issues: Troubleshooting Your Tankless Water Heater
Understanding the challenges that might arise with your water heater is essential for maintaining its functionality.
Unit Won’t Ignite: This is often due to a gas supply issue or a faulty ignition system. Check the gas line and ensure the ignition components are clean and functioning properly.
Inconsistent Water Temperature: Fluctuating temperatures are commonly caused by mineral buildup restricting water flow. Regular descaling and filter cleaning can help maintain a steady temperature.
Low or Interrupted Water Flow: If your heater can’t keep up with demand, especially in large households, it may be undersized. Installing a second unit can help meet high water usage needs.
Error Codes: These typically signal problems like installation errors or electrical issues. Consult your user manual to decode the message and find the recommended solution.
If basic troubleshooting doesn’t resolve the problem, it’s best to call a licensed professional to inspect and repair the unit safely. If you’re based in Toronto and need assistance, visit our price guide for all plumbing services costs.

FAQ: Common Questions Readers Ask About Tankless Water Heaters
What are the common challenges faced during tankless water heater installation?
Installing a tankless water heater can present several challenges that need careful attention.
Complexity in Installation: Tankless water heaters require specialised skills and experience, as they involve more complex plumbing and electrical or gas systems than traditional models.
Proper Venting: Gas-powered units need proper venting to prevent harmful gas buildup, which is essential for safety.
Electrical Capacity: Upgrading your home’s electrical system may be necessary to meet the higher energy demands of tankless units, leading to additional costs.
Space Constraints: Limited space and careful placement are important factors in installation, requiring thoughtful planning to optimise water flow and ensure easy access.
What are the potential energy savings when using a tankless water heater over a traditional one?
Switching from a traditional hot water tank to a tankless heater* can lead to substantial energy savings. Tankless heaters offer higher energy efficiency by heating water only as needed, eliminating the standby energy loss typical of traditional storage tanks. According to Natural Resources Canada, a tankless unit can be 24% to 34% more efficient for households that use about 41 gallons or less of hot water daily. This efficiency can translate to a reduction in energy bills. Over time, although initial costs are higher, homeowners can potentially experience savings of approximately $90 to $150 annually on energy bills, depending on water usage and energy prices.
How often should routine maintenance be performed on a tankless water heater to ensure optimal performance?
To ensure a tankless water heater performs efficiently and has a long lifespan, regular maintenance is essential. Annual maintenance is generally recommended, which includes flushing the unit to remove scale and mineral buildup, particularly in areas with hard water. This helps maintain efficiency and prevents potential issues from developing. It’s also important to check and clean filters, inspect the venting system, and ensure all connections are secure and free from leaks.
