Top Reasons Your Tankless Water Heater Is Not Working
A successful tankless water heater installation can enhance the comfort of your home and overall quality of life. However, your system can experience malfunctions over time that affect function and efficiency. If your tankless unit is not working as expected, it might be time to consult a professional plumber to inspect, diagnose, and address the problem. At Mr. Rooter Plumbing, we leverage extensive knowledge and expertise to handle different water heaters, ensuring homes have access to hot water throughout. Let’s delve into some reasons your tankless unit is not working to help you make informed decisions.
Mineral Buildup
The most common culprit of a malfunctioning tankless water heater is mineral buildup. Some areas have water containing high mineral content, which can accumulate in the heater, causing breakdowns, leaks, and inefficiencies. While hard water doesn’t pose health hazards, it can compromise your pipes, fixtures, and water heater. It is advisable to schedule a professional water heater demineralization with our plumbing service team at least once a year, preventing sediment buildup and subsequent repercussions.
Malfunctioning Pressure Relief Valve
If you see water pooling around the water heater, it might be a faulty pressure valve. These valves remove excess pressure in the system, and may get stuck if they don’t, causing leaks and a drop in water pressure. When this happens, the best option is to hire a professional plumbing repair service to replace the valve and repair leaks early. It is not advisable to attempt DIY repairs, as it can cause injuries and burns.
Overloading the System
If you use multiple hot water outlets simultaneously, the demand may exceed the unit’s capacity. While it is common to run the dishwasher, shower, and washing machine, you risk overwhelming the system, causing inconsistent water temperatures or complete shutdown. In such situations, consult a plumber to help you upgrade to a higher-capacity unit or install multiple heaters, if needed, to address your hot water demands.
Gas Supply Line Issues
For gas-powered tankless water heaters, inadequate gas supply can prevent proper unit function. Some of the common culprits include low gas pressure, a blocked gas line, or a malfunctioning gas valve. You can avoid such issues by working with a plumbing repair service to ensure your gas supply meets the manufacturer’s requirements and the gas line is free of obstructions. Also, investing in routine professional inspections can prevent minor issues from getting out of hand.
Electrical Problems
Tankless water heaters rely on electrical components to function, even gas-powered models. A tripped circuit breaker, loose wiring, or a blown fuse can prevent the heater from working. Check your home’s electrical panel for any tripped breakers or fuses and reset them if necessary. Persistent electrical issues may require the expertise of an electrician or a certified plumbing service.
If you are considering a tankless water heater installation, understanding these common issues can help you address minor problems yourself or seek professional help.
