What Bosch requires — and what Utah water does to it

Bosch requires periodic descaling of the Greentherm heat exchanger to keep the warranty in force, and in water at 15–25 grains per gallon that means every year. We run the full descale circulation through the isolation valves, clean the inlet filter, inspect venting and connections, and document the visit.

Bosch owners are a smaller group in Utah County, so finding a company that actually services them can be a chore. We do — and we wrote up what Greentherm owners should know in our Bosch service guide.

Questions Bosch owners ask

Do you service Bosch Greentherm 9000 / 9800 units?

Yes — the Greentherm 9000 and 9800 series and earlier Bosch tankless models. Text a photo of the unit if you're unsure.

Is the Bosch flush the same price?

Yes. $225 flat for any brand — $25 inspection plus $200 flush.

How often does a Bosch tankless need flushing in Utah?

Once a year, minimum. Utah County and south Salt Lake County water tests 12–30 grains per gallon depending on the city; homes without a softener may need it every 6–9 months.

"They helped us get back our warranty on our water heater and were super easy to work with. They showed up on time, finished early and we will definitely be using them again!"
