As most houses only have a 240 volt power supply it is not economical to retrofit an instant electric hot water system as a replacement for another type of hot water system. Before asking for a quote to change to instant electric hot water check to see if you have a 415 volt ( 3 Phase ) power supply.

An alternative may be a boiling water unit, - an Instant Gas Hot water System or a small under sink electric storage Hot Water System.
