So as a prelude to having solar panels, I installed an Eco-eye energy meter. It's been very predictable. .7 kW during the night. 1.2ish kW during the day. Spikes up to 3.5 kW when we put the kettle on. That sort of thing. So tonight we were securing the house before bed and I noticed a 2.5 kW load somewhere. Over 3 in total. We walked around the house checking but couldn't find anything on. I started switching each of the circuit breakers off in the fuse box. One 16amp unmarked breaker cut the load down to the predictable 1 kW.. I switched it back on again and the load went back up to 3.5 kW for a few seconds and then back down to 1 kW. I left that breaker off and we can't find anything not working in the house. No idea what it does. We live in a detached house and I can't imagine any of the neighbours could possibly tap into our supply. Anyone come across a scenario anything like this before?
