Performing Routine Maintenance on Your Tankless Water Heater
You’ve joined the tankless water heater revolution. Good for you—now you have an endless supply of hot water on demand and lower energy bills since you’re only heating water as needed. But your efficient tankless water heater still needs some TLC to keep running at peak performance. Neglecting maintenance is one of the biggest mistakes tankless water heater owners make. Don’t be one of them. Keep reading to learn three essential tankless water heater maintenance tips to unleash maximum efficiency and keep those lower bills coming. With some simple DIY steps, you’ll ensure your tankless water heater is churning out hot water for years to come.
Signs Your Tankless Water Heater Needs Professional Service
Performing Routine Maintenance on Your Tankless Water Heater
To keep your tankless water heater running efficiently for years to come, perform some basic maintenance. About once a month, inspect the air intake vent and exhaust vent for any obstructions. Clear away any debris like leaves, dirt or cobwebs. An unobstructed air flow is critical for operation.
Every 6-12 months, descale your tankless water heater to remove built-up mineral deposits. You’ll need a commercial limescale remover and a pump sprayer. Follow the directions to run the solution through your unit, then flush with water for at least 15 minutes. This helps maximize efficiency and prevent overheating.
Checking Filters
Be sure to check your water heater’s filters at least once a year or if you notice a drop in performance. Sediment filters trap debris to keep your unit running well, but need periodic replacement. Follow your owner’s manual to locate and change the filters. Most tankless water heaters have multiple filters, including a sediment filter, carbon filter and water softener.
With some simple maintenance, your tankless water heater can provide a steady supply of hot water for many years. But for the best performance over time, it’s a good idea to have a professional technician inspect, clean and service your unit every 3-5 years. Preventative maintenance now means fewer repairs and lower utility bills down the road.
DIY Repairs and Troubleshooting for Common Tankless Water Heater Issues
If your tankless water heater isn’t running as efficiently as it used to, it’s probably time for some professional TLC. Here are a few signs your system needs servicing:
Strange noises or leaks
If you notice odd sounds coming from the unit like clanking, grinding or hissing, it could indicate damage or buildup inside the heater. Small drips or puddles around the unit also merit a call to your plumber. Internal issues will only get worse over time and can reduce efficiency or even become hazardous if left unaddressed.
Longer wait times
Is your hot water taking longer and longer to heat up? Mineral buildup, clogs or failing parts inside the heater can slow the heating process, forcing you to run water longer before it reaches your desired temperature.
Higher utility bills
If your gas or electric bill has spiked recently even though your usage habits haven’t changed, it’s likely your tankless water heater needs servicing. Failing or inefficient parts force the unit to work harder and consume more energy to heat water.
Rather than waiting for total failure, it’s best to schedule annual maintenance with a professional plumber experienced with tankless water heaters. They can inspect, test, flush and repair or replace any parts needed to restore your system to peak efficiency and help you avoid costly emergency calls down the road. Keeping your tankless water heater in tip-top shape will ensure many more years of endless hot water and lower utility costs.
