As you are willing to pay the same rate for all your electric you may as well leave the immersion heater on 24/7 and turn the water temperature down to the lowest setting of 50C to 60C. Once the cylinder has reached the temperature the immersion will turn off and not come back on again until the temperature of the water falls which in a well lagged tank will take quite a while. The cost and the benefit difference is minimal compared to timing the water and risking running out. As the temperature if the water is at the lowest setting it will also be much safer as temperatures above 60C can be dangerous but are required in an E7 system to prevent the water running out as more cold water is used to reduce the temperature keeping more hot water in the cylinder to use later in the day.
Just sent hubby into cupboard and he turned temp down from 70 to 50.The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt.Bertrand Russell0 -
That's good but have you disabled the timer. You will now only have enough hot water for 1 full bath and will take about 1 hour for the hot water to recover so you can have another full hot bath. Most families don't have more than 1 bath an hour so you should be OK unless you have a 2 bathroom house which will make it more likely that you could find the water running luke warm then cold instead of hot.gunsandbanjos wrote: »Just sent hubby into cupboard and he turned temp down from 70 to 50.:footie:

You could play about with the timer. It would only save you pennies each day but if there is a period of time in which no large amounts of hot water will ever be used such as from 9pm to 7am you could stop the immersion from trying to reheat the water if a small amount is drawn off for example in the kitchen for washing up or washing hands after using the toilet. The lower the temperature in the cylinder then the lower the heat loss from the water will be and the more you will save. The heat losses from an average cylinder set at 70C is about 2,400Wh per day but reducing that to 50C will reduce the standing losses to about 1,400Wh per day if the room temperature is about 18C. As the room temperature drops at night the losses will increase a small amount as the temperature difference is higher.gunsandbanjos wrote: »Can't see a timer, will send him back in!:footie: Regular savers earn 6% interest (HSBC, First Direct, M&S) Loans cost 2.9% per year (Nationwide) = FREE money. 0 -
Any sign of a switch in the cupboard?gunsandbanjos wrote: »Can't see a timer, will send him back in!0 -
What I mean if someone has a hot water cylinder set at 70C and does not draw any water off then the energy required to maintain 70C is about .... oh I get it sorry 2,400Wh per day.. yes forgot the h again. I'll fix it.Tut tut. What do you mean by "2400W per day"?:(:footie: Regular savers earn 6% interest (HSBC, First Direct, M&S) Loans cost 2.9% per year (Nationwide) = FREE money. 0 -
