It’s important to maintain any appliance in your home on a regular basis. We all know and understand that spending a little time or extra money here and there in maintenance can help save major costs in the long run, but we aren’t always sure what we can specifically do. Those of you who have purchased, or are thinking of purchasing, a tankless water heater understand the cost savings these units can provide. However, just like any other appliance, it’s important to maintain these units to ensure their efficiency and cost savings are as good as possible!

 

Tankless water heaters, not unlike your coffee maker, can accumulate minerals on the inside of the heating chamber. It’s important that this mineral build up is removed on a regular basis to ensure it’s not reducing the efficiency of your unit or damaging it. Manufacturers recommend that you maintain your tankless water heater by flushing it and cleaning the screen filter on a yearly basis. 

 

Flush The System To Remove Limescale

Flushing your tankless water heater is important because it prevents the narrow water passages in the heat exchanger from being artificially narrowed by lime scale. When minerals or lime scale build up they prevent the water from efficiently passing through the system. If not enough water passes through the heat exchanger, the unit will not be able to transfer its heat to the water, causing the unit to overheat and become damaged. Any damage that is related to lime scale build-up will not be covered by traditional appliance warranties. 

 

We always start the maintenance process at the time that we install your tankless water heater. We install flush valves to make maintenance a quick, clean, and efficient process for your appliance. If you had your system installed by another company or individual without a set of flush valves, you will absolutely need a professional to come out and flush your system and possibly even retrofit a set of valves to prevent costly maintenance procedures in the future. 

We recommend that you always have a warranty approved professional maintain your tankless water heater. For those of you who are do-it-yourselfers, are mechanically inclined, or have some extra plumbing know-how, you’ll find that even the cost of tools alone might be cost-prohibitive. These tools can cost upwards of a few hundred dollars for a full set including a circulation pump, a few appropriately sized and fitted hoses, along with the proper manufacturer approved flushing solution. We charge $132+tax for our full-service tankless water heater flush. We also have the experience and purpose built equipment to complete the job and spot any failures in the system immediately.

 

During maintenance, we make sure to take time and inspect all of your equipment, the plumbing, and the other connections to the appliance. This inspection will help ensure that everything is in full working condition and that there is no wear or tear on any part of the system that could cause premature failure. The value provided in a professional inspection of your system alone is tremendous. Spotting an issue before it becomes a serious problem is an important part of maintaining your appliance on a yearly basis.

Cleaning the Screen Filter

It’s important that any accumulated debris is removed from your in-line screen filter to ensure your appliance is running as efficiently as possible. This filter is doing it’s job preventing debris from getting into the system, but it’s important to help it do its job by removing the debris it collects. We take some time to inspect the filter for any damage or wear that might have occurred during regular operation. Even for something as simple as cleaning the filter, we recommend a professional complete the task. We always make sure to complete this important step in our full-service tankless heater flush.

 

Final Thoughts

While some sources might claim that it is a relatively simple and inexpensive process to maintain your tankless water heater yourself, it’s often more cost effective and a better idea to have a professional come to complete a full service of your appliance. This is doubly important if your unit is still under warranty to ensure that you’re staying within that warranty’s limitations. Our professional staff know and understand how to protect your warranty by using the proper equipment, techniques, and flushing supplies. We additionally offer maintenance plans for all of our appliances that can help reduce the cost of this regular maintenance while also ensuring that you’re serviced with priority each year.
