Hot Water - always on or timed?
I have an Ideal Logic Air R32, Ideal Halo Air settings tell me to keep the hot water set to “always on” rather than timed as this saves the most energy.
I can kinda see the logic - keeping it topped up to 45/50C is cheaper than heating it from cold every time, but information online seems to imply either heating during cheap hours or during midday peak temps is cheaper/more efficient:
Who’s right?
