I have E10 at my house and have recently shifted to OVO. Many posters on this website seem not to understand how to get the best out of E10. I make sure that I shift as much of my power usage to the three cheaper periods. I have timers on the washing machine, dryer and dishwasher and regularly check that they are “in synch” with the cheaper times. That’s easy if your hot water heater has a neon or LED on the switch as mine does. (Alternatively if your hearing is good you can actually hear the water heating element power up– sounds like a kettle!) My meter does NOT change to BST so I leave the other timers on permanent GST as well. The one thing that is a bit of a nuisance- most newer washing machines etc have electronic controls which will only hold their settings when powered on. How I get around this is to temporarily power the device(over-ride the time switch or plug in to a non-switched socket) whilst making the various settings then unplug and replug into the timer. The settings will then “stick” and all will work when the “cheap time” occurs. When I upload my meter readings to OVO I consider myself “failed” if the website doesn’t query my readings! My cheap rate consumption (4) is always much higher than my normal rate (1) It’s entirely honest but quite satisfying for a nerd like me!20th December 2015 at 1:31 pm #1844MKingParticipant
Our meter was reprogrammed by EDF for E10 from E7 recently and we are now using approx. less than 30% peak and more than 70% off peak with greater comfort as the storage heaters and the immersion work at times that we can benefit from heat and hot water. A cheap timer with a battery powered clock on the immersion heater means that we don’t need all 10 hours to get enough hot water: all positive so far…
Anyone with old-style storage-rads should change from E7 to E10 just for comfort let alone any saving of money…28th November 2015 at 9:58 am #1252MKingParticipant
Now using E10 and our ratio of cheap to expensive (night to “day”) rate has slewed drastically towards the cheaper 6.7p/kwh use.
Washing and other high cost can be done between 1pm and 4pm or in the late evening and there is now no need to charge storage rads overnight to lose all the heat in the morning with little or none left for the afternoon and evening.
We will be using iSupply from Dec. so will comment on their service using their E7 as E10 which is much cheaper than EDF…
If you use individual timers on each of your storage rads on the immersion heater and have a delay on the washing machine you can fine tune the system radically; e.g. we now heat water only 3-5am and do not need the full 3 hours final water-boost in the afternoon nor any time of the evening 2 hour period…
