Reasons for Tankless Water Heater Maintenance

Tankless water heater maintenance is a must. Your unit typically needs routine maintenance every six months to function at peak efficiency. Regional factors like hard or soft water, usage frequency, and age also are considerations. Primary reasons for regular maintenance include:

Hard Water: Hard water affects both tankless and traditional models. Hard water contains minerals, mainly magnesium and calcium which may build up inside the heat exchanger.

Improved Water Flow: Over time, minerals will plug up the passages where the water flows, significantly affecting water flow speed. Eliminating minerals improves flow.

Utility Bill Savings: A well-maintained heater will not work harder than necessary to deliver hot water. But a heater that is not cleaned out on a regular basis will eventually shorten the water heater’s lifespan, work harder to produce heat, and cost you more on energy bills.

Avoid Costly Damages: A buildup of minerals and contaminants can cause irreversible damage and unwanted, expensive repairs. This also will shorten the life of your unit.
