The question here is not just the high energy bill, which is too high and we are looking at ways to reduce, but simply the change made to switch off the Naim and replace with the Bantam One, and also the discovery that a tube heater and the washing machine has been turned off at the wall, and then the change in the weekly meter reading on a Monday morning.
The change is only accountable by what has been switched off.
GadgetMan worked out that this is 447 watts which is attributed to the Naim, and a tube heater. I do not thing the switching off of the washing machine makes any difference, there is only a led panel on the front that gets switched off.
The old Naim I have does not go into a stand-by mode, power is supplying the transformer without any energy saving circuit to reduce when no load is sensed (that was added only recently certainly not in the 80’ and 90’s, maybe even later?)
There are other changes we could make (turn off all the computers, all the lights…) but just for now only the changes mentioned regarding the Naim, tube heater and washing machine have been made, so surely must be all that is affecting the weekly meter reading.
(By the way, I really do not like led lighting, and the essentially single wavelength of emitted light does not suit me. For the sake of very few lamps in the house the saving and discomfort of the light quality is not worth it for me. Florescent tube in kitchen, standard lamp in the sitting room, hall light and stairs light hardly on, desk lamp on my desk in the dining room, center light hardly ever on, center light in two bedrooms hardly ever on, bedside light occasionally, light in the third does not work so desk light occasionally, and finally the loo light occasionally and the bathroom when we bath).
We really are at a bit of a loss to see where 175kWh is being used, hence the whole exercise.
Suggestions of a more methodical approach with a wattmeter plug must be the next step, but I thought where I started just making a small change in what was running in the house made some sense.
The computers are set to sleep mode (and here it is just a pc and an imac, I have already switched off a pc I used for backup and a macmini used to run old programs that stop with High Serria, and there is an HP laserJet 1320 printer).
Don’t have a smart meter.
