A couple of handy tips from my Aonghas for fellow money saving experts.
TIP #1 -- When there is a substantial tariff rise on the cards, as there will be on April Fools' Day, it is prudent to grossly over-estimate usage to date, and provide the supplier with a customer meter reading to confirm that.
Thereby bagging many months of future energy usage at yesterday's cheaper prices, albeit paid for up-front.
TIP #2 -- As many will know, my Aonghas is an industrial user of electricity. What with his Bitcoin Mining Farm in the spare bedroom, and his year-round Indoor Tomato Growing in the loft.
On occasion his Peak Load has blown the main house fuse. Originally a 100 amp, he upgraded it to a slow-blow 8mm bolt, see below.
But for fear of straining or even overheating the electricity meter, Aonghas came up with a further safeguard that also keeps our bills in check.
The ENSTO SLIW50 insulation piercing connector. Used normally for tapping Aerial Bundled Cables, my Aonghas has them bolted to our meter tails, and feeding his cryptomining rig and the loft plantation. See below.
Thereby lightening the load on the consumer unit, and doubtless prolonging the life of the meter. A win win for everyone you must agree..
