Frequently Asked Questions
Are Tankless Water Heaters Suitable for All Homes?
Most homes in Ajax can benefit from a tankless water heater. However, the suitability depends on specific water usage needs, location, and existing plumbing systems. Our team can assess your home to determine the best system fit and installation approach. It’s important to consider factors like the home's layout and the number of occupants to ensure the system meets your demands effectively.
What is the Typical Lifespan of a Tankless Water Heater Compared to a Traditional One?
Tankless water heaters generally boast a significantly longer lifespan than their traditional tank-style counterparts. A conventional storage tank water heater typically lasts around 8 to 12 years, with its lifespan often limited by internal corrosion of the tank itself. In contrast, tankless water heaters, if properly maintained, can last 15 to 20 years or even longer. This extended longevity is a key selling point, as their design minimizes sediment buildup and tank corrosion. With proper care and regular maintenance, many homeowners find that their tankless water heater performs reliably for two decades or more.
What Factors Determine the Right Size Tankless Water Heater for My Home?
Choosing the right size tankless water heater for your home is crucial for ensuring you have sufficient hot water and optimal energy efficiency. The most critical factors are the flow rate and temperature rise needed simultaneously. Flow rate refers to the number of gallons per minute (GPM) of hot water your household typically uses at peak times (e.g., how many showers and appliances might run at once). Temperature rise is the difference between your incoming cold water temperature (which varies by season and location like Ajax) and your desired hot water temperature. A professional will combine these factors to ensure the unit can meet your hot water demands without being undersized or oversized.
How Long Does a Tankless Water Heater Installation Take?
The installation of a tankless water heater typically takes longer and is more complex than replacing a traditional tank model. For a standard replacement in a residential home, a professional installation can generally take between 3 to 5 hours. However, if it's a first-time tankless installation or requires significant modifications to your existing plumbing, gas lines (for gas models), electrical wiring, or venting systems, the process can extend to 4 to 8 hours, or even a full day. These modifications are often necessary because tankless units have different requirements than traditional tanks. A licensed professional ensures all connections are safe and up to code.
How Can I Prepare My Home for a Tankless Water Heater Installation?
Preparing your home for a tankless water heater installation can help ensure a smooth and efficient process. First, clear the area around the old water heater and the proposed new tankless unit location, providing technicians with ample workspace. If you're getting a gas unit, ensure your existing gas line is sufficient; often, a larger line is needed, which your plumber can assess. For both gas and electric units, confirm your electrical panel has the capacity for the increased demand. Also, verify that the space is well-ventilated, especially for gas models requiring proper exhaust venting.
What Maintenance Does a Tankless Water Heater Require?
Tankless water heaters require less maintenance than traditional systems, but regular descaling and flushing are vital to maintaining efficiency. We offer ongoing support and maintenance plans to keep your system running smoothly. Routine checks and maintenance help prevent scale buildup and ensure the unit operates at peak performance, maximizing the lifespan of your investment.
Can I Save Money with a Tankless Water Heater?
Yes, tankless water heaters are known for reducing energy bills due to their efficient operation. Over time, this can lead to significant savings, especially in homes with high hot water demand. By using a system that heats water on demand, you reduce wasted energy, which reflects in lower utility bills, making it a financially sound choice.
