Prosper's rapid growth has produced a large stock of newer, large-footprint homes — many with tankless water heaters installed to handle the high hot-water demand of 4–5 bathroom houses. Those units are often 3–8 years old now, which puts them in the window where deferred descaling begins to show up as reduced performance and error codes.
NTMWD water in Prosper runs moderately hard — similar to Frisco and Plano. Without annual descaling, heat exchangers in Prosper tankless units accumulate scale that reduces efficiency and eventually triggers failure. We service all major brands, install scale filters, and handle new tankless installations for homeowners converting from tank units.
