Yes. Most licensed plumbers in Aurora, Colorado descale tankless water heaters. It is one of the more routine water heater maintenance services in Aurora, and local homes usually need it about once a year. Aurora’s hard water leaves mineral scale inside the heat exchanger fast, so regular descaling keeps the unit running and protects the warranty.
If your hot water goes lukewarm halfway through a shower, or your unit keeps flashing an error code, scale buildup is usually the reason.
Descaling is the standard way plumbers clear hardened mineral deposits out of a tankless water heater. The technician hooks a pump and hoses to the unit’s service valves, then circulates a descaling solution, often white vinegar or a commercial cleaner, through the heat exchanger for about 45 minutes to an hour. That solution dissolves the calcium and magnesium that Aurora’s hard water packs onto the inside of the system. Almost every full-service plumber in the area offers this, and major tankless brands like Rinnai and Navien both treat yearly service as part of keeping the warranty valid. That makes tankless water heater maintenance in Aurora less of a nice-to-have and more of a requirement.
How often you need it depends on your water. Homes on Aurora’s harder lines may need it every 9 to 12 months, while a household with a water softener can sometimes stretch closer to two years. A plumber can check your scale level during the first visit and tell you what schedule makes sense for your home.
Is flushing the same as descaling?
Not exactly, though people use the words like they mean the same thing. Flushing means running water through the system to push out loose sediment and grit. Descaling goes further. It circulates a cleaning solution to dissolve the hard mineral scale that water alone cannot remove. For a tankless unit, descaling is the job that actually matters, and a flush is usually the rinse step at the end.
What do plumbers charge to descale a tankless water heater?
In the Aurora area, a professional tankless descaling usually runs about $150 to $300. The price depends on how much scale has built up, whether the plumber adds a full inspection, and if you bundle it with other service. Buying it as part of a yearly maintenance plan is almost always cheaper than calling for a one-off visit, so it pays to reach out for a quote before the unit starts acting up.
What happens if you don’t descale your tankless water heater?
Skipping descaling lets scale pile up until the unit struggles. Here is what tends to happen, roughly in order:
- Weaker, lukewarm hot water and lower flow
- Higher gas or electric bills as the unit works harder
- Error codes and random shutdowns
- Cracks or damage to the heat exchanger
- A voided manufacturer warranty
- A shorter lifespan, often years off the unit’s life
Once scale damages the heat exchanger, you are no longer dealing with simple upkeep. You are looking at professional water heater repair in Aurora, and that bill lands in a different league. Staying on top of yearly service is far cheaper than replacing a heat exchanger or the whole unit.
Should you flush or descale first?
Descale first, then flush. The descaling solution needs to dissolve the mineral scale before anything else, so the plumber circulates it through the unit first. After the scale breaks down, a clean water flush rinses the loosened debris out of the system. Doing it in that order leaves the heat exchanger clean and ready for another year.
