Horstman e7 bx help

TAYLOR90 · Feb 12, 2022

Hi I have recently moved into a new flat and looking for help regarding hot water please

In my old flat i had a water tank in a cupboard and had a on/off switch on the wall, which i left on constantly so always had hot water, simple.

this new place is completely different, there is a water tank in the cupboard in the bathroom but no on n off switch. I am guessing it is meant to heat up over night but it doesnt, i get up in the mornings and have cold water/luke warm water.

The only way i can get hot water is to put the horstmann e7 bx box boost on which is in the hallway, but this is not cost effective as i worked it out the other morning. I put it on boost for 2 hours so i could get a bath and could see the smart meter going up and up during those two hours. in the 2 hrs it cost £1.26 to heat it up.

am i missing something here? is there a hidden switch somewhere or is the water tank not doing what it should be doing.

i have attached pics so hopefully one of you will be able to help me out,,
many thanks

Do you actually have E7?
Horstman switch needs to be in timed position

My granddaughters toy car has Porsche on it, but it ain't

Need a pic of your meter
Have you had a smart meter fitted recently?

E7 gives 7 hours cheap electric at night. Some meters are fitted by a total cretin and he/she should go back to,selling loft insulation
