    Questions & answers

    how much doess a 3 phase instantanious hot water unit cost to run Doug · 2025-04-11
    Hi Doug, this will depend on your wholesale energy costs and time of day, I can't give a dollar cost - it's going to vary for everybody. Stiebel Eltron also do not provide energy outputs because if you take a look at the second page of the datasheet we've uploaded, it's all dependent on flow rates and temperature selected (a lower flow rate and temperature is going to use far less energy than the opposite). Kind regards, Adam from Appliances Online. AdamD, Appliances Online
