Classification: CPC F  B  C | IPC C  F

Claim 9:
10. A water heater comprising:
a water inlet;
a water outlet;
a heating chamber connected to the water inlet and the water outlet, wherein the heating chamber is configured to heat a flow of water received from the water inlet and output the flow of water to the water outlet;
a conductivity sensor configured to measure an electrical conductivity of the flow of water and output raw conductivity data indicative of the electrical conductivity of the flow of water; and
a controller configured to:
receive the raw conductivity data from the conductivity sensor;
determine calculated conductivity data based at least in part on the raw conductivity data;
output instructions for initiating a descaling cycle based at least in part on the calculated conductivity data;
subsequent to initiation of the descaling cycle, output instructions for terminating the descaling cycle in response to determining that an increase in the calculated conductivity data has stopped.
