Clogging of the tankless by sediment is not an issue because the tankless has a fine mesh filter on the input which prevents anything from every entering the machine. We have hundreds of these installed, and we do not get calls from people asking how to clean the filter (it’s an easy process) even on the many houses with galvanizned plumbing on which we install these. Calcificaiton is the precipistaion of minerals dissolved in water which settle on waterway surfaces.

CALCIFICATION IS NOT A PROBLEM IN TANKLESS WATER HEATERS IN SOFT WATER AREAS WITH TOTAL DISSOVED SOLIDS OF <60-80 PPM.
Marin, the East Bay and the Penninsula have soft water. In hard water areas (i.e. areas with well water, Fairfield or San Jose) we recommend either a whole house water softener, a dedicated small softerner just for the tankless called a scaleschielf or the installation of a flush kit so the tankless can be easily flushed every few years.
