Gas vs. Electric Tankless Water Heaters
Gas Tankless Water Heaters
Ideal for larger households or homes with higher hot water demands, these systems provide fast heating and consistent water flow. Our journeyman plumbers ensure proper gas line installation and venting for safe, efficient operation.
Electric Tankless Water Heaters
Perfect for smaller homes or properties without natural gas access, electric models offer quiet, clean operation and flexible installation options. These compact units can be installed near bathrooms, kitchens, or laundry areas for point-of-use efficiency. No matter which type you choose, we’ll handle every aspect of your tankless water heater installation — from selecting the right model and size to connecting plumbing and electrical components.
Professional Installation and Maintenance
At Drain Terrier, our installation process is performed by licensed and experienced plumbers who understand both the technology and the local plumbing code. Proper setup is critical for safety, performance, and warranty compliance.
We also offer ongoing maintenance and descaling services to protect your investment. Over time, minerals like calcium and sediment can accumulate inside your water heater, reducing efficiency and flow. Our technicians perform routine cleaning, inspection, and performance testing to keep your system running at peak condition.
If your existing unit is experiencing reduced water pressure, fluctuating temperatures, or a leak, our home plumbing repair team can quickly diagnose and restore your water heater to optimal performance.
Signs That a Tankless Water Heater Needs Repair
While tankless water heaters are known for their durability and efficiency, like any appliance, they may require repairs over time. Recognizing the signs of potential issues early on can help prevent major breakdowns and ensure a continuous hot water supply. Here are some common signs that a tankless water heater may need repair:
Insufficient Hot Water
If you notice a decrease in the amount of hot water or a sudden drop in water temperature during usage, it could indicate an issue with the heating elements or a flow restriction.
Fluctuating Water Temperature
Inconsistent water temperature, where the water alternates between hot and cold, may be a sign of a malfunctioning temperature sensor, heating element, or flow sensor.
Strange Noises
Unusual noises such as popping, banging, or hissing may suggest mineral buildup within the unit. Over time, mineral deposits can affect the heating elements and reduce efficiency.
Error Codes on Display
Most tankless water heaters are equipped with digital displays that show error codes in case of malfunctions. If you see an error code, refer to the manufacturer’s manual or seek professional assistance to diagnose and address the issue.
Leaks or Water Pooling
Any visible leaks or water pooling around the unit should be addressed promptly. Leaks can damage the unit and surrounding areas and may be caused by issues such as loose connections, faulty pressure relief valves, or internal components.
Delayed Ignition
If you notice a delay in ignition or a pilot light that goes out frequently, it could be a sign of a gas supply issue, a malfunctioning ignition system, or a dirty burner.
Mineral Buildup
A decrease in water flow or pressure may indicate mineral buildup in the pipes or the heat exchanger. Periodic descaling or flushing of the system may be necessary to address this issue.
Unusual Odors
Strange odors, particularly a rotten egg smell, are often a sign of bacteria growth in the water heater. This can occur in the anode rod or the water supply. Flushing the system and replacing the anode rod may be necessary.
Age of the Unit
As tankless water heaters age, their components may wear out, leading to decreased efficiency and potential malfunctions. If your unit is reaching the end of its expected lifespan, consider proactive replacement or repairs.
If you observe any of these signs or experience other unusual behavior with your unit, it’s advisable to consult with a professional technician. Regular maintenance and timely repairs can extend the lifespan of your unit and ensure a reliable supply of hot water in your home.
