Does anyone have a base load that they can't track down?

In a previous house I could get the electricity consumption down to zero but in my current place there is always something consuming power even when I think everything is turned off. I think this could be down to a mains fire alarm or ventilation system. Old doorbell transformers are another candidate but I can't see any evidence of those. It could also be the boiler.

The focus is usually on big power consumers. However, appliances that are always drawing power are also important. The area under the curve can add up to more than a powerful item used for a short time.

When I was working out my baseload a few weeks ago, I found that my microwave was using about 100 W while on standby! Clearly there was something wrong with it - I replaced it with an identical make and model which uses only 5 W.

I assume you have isolated the problem to the ring-main by removing other fuses? Your boiler must have an isolator switch for safety? How high is your baseload? Doing an exercise to get to zero is something worth doing, I must try that sometime.

I can get it to zero using the breakers but that isn't very useful. I want to know which appliances I can turn off to reduce the vampire load. If they are hard wired in then I don't have many options as I rent the property. It is a good exercise to perform. Previously I found appliances that have a significant standby current and turning these off at the socket when not in use made savings. The base load power isn't that high but over a long period it adds up to a lot of energy. I very much doubt the wiring is a problem. Transmission losses really only apply at grid scale. You need a big load on the end of a long wire for this to happen. If my ring main has large resistive losses when almost everything is off then I have a serious fire hazard on my hands! :)

Hi js, Could you perhaps have something on in the attic? I once struggled with the same problem, then remembered that I have an ultrasonic mice repellent in the attic, on 24/7.
