Expert Tankless Water Heater Routine Maintenance

Water Heaters, Like Cars, Need Routine Maintenance

The goal of routine tankless maintenance is to prevent scale from building up inside the heat exchanger, keep filters, igniters, fans and burners clean, and check gas pressure, proper venting and system performance. Over time, we’ve found that the average household benefits the most from annual service plans. With proper maintenance your tankless water heater will be more efficient, more reliable, and have a significantly longer service life.

Your Manufacturer and Warranty Recommends Routine Maintenance

Control compartments, burners, and circulating air passageways of the appliance must be kept clean. Tankless manufacturers warranties require a licensed professional inspect your system annually. Running your system without maintenance will decrease efficiency and lifespan.

What is the price for routine maintenance?

For most residential tankless water heaters in the Denver metro area, routine maintenance runs $199. The cleaning takes about an hour. Other charges may apply (with your advanced authorization) for a handful of older models which are more difficult to clean, or locations that are more difficult to access (crawl spaces or attics). It is standard practice to charge trip fees for locations greater than 20 miles or 30 minutes drive from our office. Your tankless manufacturer, and our years of experience strongly recommend routine maintenance. Professional service ensures your water heater will continue to provide you the luxury of endless hot water for decades.

  • Maintain system energy efficiency
  • Remove mineral and scale build up from inside the heat exchanger
  • Clear fan assembly of dirt and debris (pet hair, dust, moths and insects)
  • Inspect gas, plumbing and venting for performance and safety
  • Enjoy consistent hot water temperature and endless hot water supply
  • Prevent avoidable emergency service calls

Improperly maintained water heaters can fail many years ahead of schedule resulting in premature replacement potentially costing thousands of dollars. Improper maintenance (such as but not limited to scale build-up, freeze damage, or vent blockage) might void your warranty.
