Providing tankless water heater repair near Boerne in the Texas Hill Country
What can go wrong
6 common tankless water heater repairs:
1. Mineral and Sediment Build-Up
It’s a known fact that the Texas Hill Country has some of the hardest water in the country. In fact, Boerne has a hard water mineral concentration of up to 358 mg/L.
Â
It’s important to check your tankless water heater for mineral and sediment buildup inside the unit. Build-up can damage your unit’s heating elements and impair proper functioning.
Â
Regular maintenance is necessary to keep your unit in top condition and to prolong the life of your tankless water heater.
Â
If your home uses well water, quicker build-up of minerals is common. This makes it difficult for water to travel to the heat exchanger. Make sure to check your water filter to clear debris that can become trapped and impede water flow.
Â
It is recommended to have a professional plumber perform routine maintenance once or twice a year to clean or replace your water filter, clean the air filter if you have a gas unit, and descale and flush the system.
Â
Water softeners will also help to slow the build-up of minerals.
Â
For regular maintenance of your tankless water heater, call the plumbing professionals at 830-446-5227. Olde Town Plumbing is the plumbing service folks call for all their plumbing service needs.
2. System Overload
It is important to choose the right size tankless or on-demand water heater for your home. If you choose a unit that is too small to meet the needs of your family, you will overload your system causing it to shut down.
Â
Tankless water heaters heat water as you need it. They are limited in the amount of hot water produced at one time. If your unit is struggling, you may be placing too many demands on your tankless water heater.
Â
Consider upgrading your unit to a higher-capacity model or adding a second tankless water heating unit.
Â
The experts at Olde Town Plumbing would be happy to evaluate your system and discuss the best options for your home and family.


3. Blocked Air Supply or Exhaust
If your tankless water heater displays an error code, the air supply or exhaust may be blocked. Gas water heaters display this safety feature to prevent harmful gas leaks when an exhaust pipe closes.
Â
In addition, if your tankless water heater stops heating, it may be a safety feature. Most units will automatically shut off as a safety measure to protect the unit and protect against other safety hazards.
Â
It’s important to inspect all venting pipes to make sure they are connected properly and are free from any puncture holes. A crack or hole in the gas pipeline or a loose exhaust pipe can cause dangerous gas leaks inside your home.
Â
Check to make sure all vents leading outside your home are clear. Bird nests, beehives, or rodent nests or other pests can block your venting and cause issues with your unit’s airflow.
4. Ignition Failure
Failure of your tankless water heater to ignite is a sign you have an issue with your gas supply. Make sure your propane tank is full and that your gas valve or water valves are fully opened. If your unit still fails to ignite, call us at Olde Town Plumbing to schedule an inspection.
Â
One of our knowledgeable technicians will come out and do a thorough inspection and get to the root of the problem. This is not a job for the do-it-yourselfer. You want to call a professional to ensure that the gas line repair is done appropriately and safely.
Â
You can count on us to give you an honest assessment and upfront pricing. We’ll work as quickly as possible to get your tankless water heater functioning again.

5. Flame Failure
If your tankless water heater has a flame failure, it may be caused by low gas pressure or an electrical issue. Just like ignition failure, this is a job for professionals. We’ll inspect to see if your gas line is too small, or if you have a regulator failure. Other possible causes include combustion or venting issues. Because of the nature natural gas, we don’t recommend installing a gas water heater as a DIY project.
6. Broken Heating Elements
Tankless water heaters can be powered by either natural gas or electricity. If your electric unit has failed, similar to a traditional water heater, the issue may be a broken heating element, thermostat, or other wiring issues.
Â
Tankless water heaters are constructed for high performance and reliability. But sometimes, things don’t work as they should. When something goes wrong, you can depend on Olde Town Plumbing to be there when you need us.
