When it is not practical or cost-effective to use a traditional hot water heater, a tankless unit can do the job in a much smaller space. These highly efficient units require little maintenance and servicing once every year or two is typically all that is needed. Trust the pros at All Valley Plumbing for tankless hot water heater service & repair in Mukilteo. We have the essential skill and experience to take care of any issues you may have with your tankless water unit.
It is uncommon to have operational issues with this appliance, but it can occur. If your water does not heat properly, there is a lack of hot water for multiple purposes at the same time or the unit shuts off while in use, contact a professional. The unit can be repaired most of the time.
Flushing or descaling of the water heater is suggested on a regular basis to ensure effective operation. This service helps to prevent buildup of calcium inside the unit, which can cause the burner to heat at a higher temperature. Water hardness often governs the frequency of this kind of maintenance. Cleaning out the unit can also prevent a heat exchanger leak, which is the most common issue occurring with tankless units.
Since the inner mechanisms of tankless water heaters are complicated and involve many water and gas lines, in addition to computer apparatus, informed intervention is required. You can rely on All Valley Plumbing to evaluate the problem with your unit and provide you with an honest appraisal for repair. Phone us today at (425)357-7420 to schedule an appointment for tankless hot water heater service & repair in Mukilteo.
