The variables
Hot water volume used, cold inlet temperature, stored set-point, ambient temperature, insulation quality, standing losses and the condition of the unit. Change any one and consumption changes.
Why fixed savings claims are unreliable
A percentage saving quoted without knowing your demand, your set-point and your existing system's condition is guesswork. We would rather assess your property and explain the expected behaviour honestly.
What you can control
Set-point discipline, fixing dripping hot taps, insulating pipework, sensible scheduling and keeping the unit serviced all measurably reduce consumption.
