Tankless water heaters are so much better than the conventional water heaters in so many ways. First and foremost, you don’t have to worry about using up all the hot water or worse, worry about someone having already used up the hot water before your shower!
The tankless design makes sure that you have your hot water right when you need it. They are compact, energy-efficient and last longer than the conventional tanked water heaters. However, like all other appliances in your home, a proper maintenance of your tankless heater will ensure that you can enjoy your hot water without any interruption and still be environmentally responsible, talk about a win-win situation!
Why is regular maintenance is necessary
Although tankless water heaters do not require an extensive maintenance, over time, accumulation of minerals from the water on the insides of the heating chamber may slowly corrode away the heating surface and reduce the efficiency of the mechanism. All that is needed to ensure that your tankless water heater is in a great shape is a periodic purging the system to get rid of the accumulating minerals.
Here are some tips to help you get rid of the nasty stuff accumulating within the heating surfaces and get your appliance work as good as new!
- Safety comes first. Whenever you are in the mood to spruce up your water heater the first step is always turning the power source off- shutting off main gas line or flipping the electric circuit breaker, for example.
- The second step would be to turn off all the three valves (Red- hot water, Blue- cold water and a third for the main line carrying the hot water to your home) on the tankless water heater.
- Next, remove the purging valve (easily identifiable by a small handle in the shape of a “T”). This will make sure that you are relieving any pressure inside the heater (be careful and remove the valve slowly!) so that water does not shoot out and potentially burn you!
- In the next step, attach your hosing lines that came with your heater system to the three valves you shut off in step 2. You may want to consult the manual to do it correctly. These hoses will allow you to flush your heater system.
- Open the purge port valves by turning them to the ‘open’ position (vertical in most cases).
- Use about 3 gallons of white vinegar to flush out the system. Using harsh chemicals is not recommended by most manufacturers. Perform the purge with white vinegar per the manufacturers instructions (may take unto an hour).
- Once the purging is complete, remove the hosing and reattach the connections to the respective valves.
- Restart the system according the instructions in the operating manual.
Let the water run in your sink for about a minute or so to get rid of all the air, and violà! Your water heater is as good as new!
