A tankless water heater can last several years without requiring too many repairs. However, you have to regularly clean and maintain it in good condition if you wish to keep the machine running optimally for long. And if you are planning on cleaning the heater for the very first time, then be sure to keep the following tips in mind.
1- Switch off The Power
Tip number one – always switch off the heater before you tinker with it. Never ever keep the machine switched on since that might result in an accident which can trouble you for life. If you are using an electric tankless water heater, switch off the circuit breaker. And if your heater is gas-based, then switch off the supply from the gas line.
2- Turn off the Valves
Your heater will have three water valves attached to it. Remember to close them when you are trying to clean the heater. This will stop the cold water from entering the heater while also ensuring that the hot water in the heater does not come out when you are cleaning them. If you keep the valves open during the cleaning process, then there is a risk that the hot water might pour onto your body. So, avoid such potential problems by keeping all valves turned off.
3- Clean the Heater Using Vinegar
When cleaning the insides of the heater, make sure to use vinegar instead of chemical solutions. If you use chemicals, then some residue will likely remain in the heater no matter how thoroughly you clean it. And the next time you or any of your family member drinks water from the heater, they might ingest these chemicals which can go on to do great bodily damage. It is to avoid such scenarios that vinegar is recommended to be used. Just use 3 gallons of vinegar to flush the system, and your heater will be properly cleaned. Remember that this cleaning process can take anywhere from 45 minutes to an hour. So, only do it when you do have time. Don’t do a rush job and leave the heater partially cleaned.
4- Check the Manual
Always read the manufacturer’s manual before trying to tinker with your heater the first time. Even if you have handled other heaters before, you need to understand that the specific model may be different from the ones you have dealt with. As such, you might end up doing certain things wrong and damaging a component of the system. And in the worst case scenario, you might even nullify the warranty on your tankless water heater. So, avoid taking such risks. Read the instructions of the manufacturer, and make sure that you abide by them.
And in case your existing water heater is past its prime and you are looking to buy a new one, consider getting a tankless system. Plus, when deciding on a tankless hot water heater, be sure to check out the internet reviews before zeroing in on a model. Reading such expert reviews will help you find the perfect heater for your home.
