Tankless water heaters are one of the best ideas for upgrading a home’s plumbing. Thanks to a tankless water heater, a household can enjoy an unlimited hot water supply (no more rushing not to be the last one to take a shower in the morning) while paying much less on monthly energy bills. A tankless water heater should also last longer than a conventional storage tank model and need far fewer repairs.
If you already enjoy the benefits of a tankless water heater in your home, we want to make sure that you continue to get the best use from it. Even though a tankless water heater will run into a smaller number of malfunctions than a standard water heater, they can still happen. Below is a guide to what you can do when your water heater starts to act up.
- If you aren’t getting any hot water at all… There’s a chance that the system has lost electrical power (and even gas water heaters use electrical power to operate). Check on the circuit breaker panel to see if any breaker has tripped. Also, look on the water heater’s display panel for an error code that may explain the loss of power. Call for professionals if you can’t find a simple solution to the problem.
- If the water isn’t as hot as it should be… Lukewarm water is often due to multiple taps coming on at the same time. This is one of the few drawbacks of using a tankless water heater. If this is a consistent problem, we advise that you have a second tankless water heater installed. This is a solution that works for many larger homes. Have a technician examine the system and see if there’s a repair issue with the water heater before making any choice for a new installation, however.
- If the water is too hot… This opposite problem often occurs because the setting on the water heater is too high. It might also be the fault of a broken temperature sensor, which will require a professional to repair.
- If the water pressure is too low… This might be a municipal water supply issue. Wait for an hour, and if the problem persists, call for a plumber to look into both the water heater and the rest of your plumbing.
