Hello, I am hoping that I have found the right place for help. I have for months had an issue with my water heating. Lived in the property for over 5 years without any prob's until this year, it is a electrical system with a single rate meter (according to my supplier) we also have storage heaters. We have a fused spur in the kitchen along with a boost, I have noticed that the spur comes on between 1am and 8am everyday however I get no hot water unless we use the boost in which case its red hot. We have to do this every day and it's costing a fortune (ÂŁ144 a month) 3 bed maisonette!

I've had both plumbers and electricians out, internal electrics have been tested. Main fuse is fine, both immersions are working, tank was nearly new when we moved in. Plus the boost works so the water does heat up. We were told to contact the supplier as it might be a timer issue. We don't have a timer for the water and the supplier advised that it is a single rate meter and the electic is on all the time. So how does the fused spur know when to come on and when it does why does it not heat the water???

Uber confused and stressed to bits... I have a young family and need this sorting for Winter coming. Any help and advise would be amazing... cheers Ben
 
if it was a proper eco 7 you would have this or maybe you do as this is a timer and boost or do you just have aboost plus send in pictures of the fuseboard area and boost unit for a definitive answer

Forgot to add that you may have a common timer at the consumer unit anyhow pictures please
 
my money is on the stat to the bottom heater or the fuse to off peak/or s/spur is off/blown. Its the first two things i always check on a call like this. The OP says the elements were checked and mentioned boost so must be an eco clock as oldtimer has posted so not much left to look at. Still all this makes the last sparks look a bit silly, I would get him back for free but easy for me to say when your in the game.
 
Needaspark me thinks you are spot on yes the off peak side may not be working but a spark worth his salt with a trusty multimeter could measure the resistance of the circuit back at the off peak board if they get 18-19 ohms then yep it ok if not then they move on to the element and measure across the nuetral and pre then after the thermostat if after (the leg going on to the element) gives you 18 ohms then replace the stat I must say though 90% of faults I look at like this is the thermostat the other 10% is a burnt out connection on the element or indeed a duff element.


Still waiting on a couple of nice pictures though my with all this technology nowadays this should be manditory on this forum

There are some meters that changeover using radio teleswitching (BBC Radio 4 Long wave carries the superimposed switching data) which allows the electric companies to vary the off peak periods so there is not a timeswitch to control the economy 7. From the original post it sounds like there is a wiring issue or possibly a failed contactor or relay
 
Hey, thanks for all the advise. Oldtimer sorry for leaving you hanging, not intentional. Due to my working hours it's not always possible to be around. As an update, I had had a plumber freind replace the bottom immersion based upon the information given. That has solved the problem HURAH!. shame this could not have happened weeks ago. Thank you truely for all the advise I would of still been stuck now. It is also an eco 7 meter. Cheers Ben
 
Well here I am again!!! NO F'IN HOT WATER.... not even a week later..

Now i've noticed that the spur that comes on to heat the water overnight (usually between 1am and 8am) does not come on any more. Boost still works, changed the fuses and checked the spur which isnt a fused one still no luck. Again I have been asked to look for a timer?? again I CANNOT find a timer. I've ased Neighbours who have no timer.
The emmersion was replaced which doesn't have a timer just a thermo. My mate who replaced it asked me to check the reset button which I have and that has'nt done anything.

Back to square one... wonderful... :cuss:
 
fuses. There are two on the box when i've looked. 15amp chunky blue ones.

Here is my set up, pic 1 is the fuse box, two fuses that say 'water heater', pic 2 tank with two immersions, pic 3 is the electic points for the tank, pic 4 is the boost switch and spur that comes on 1am to 8am, pic 5 is the meter. This is all that I know i've got as a set up.
 
This is a big thread for a small problem

If you want to know if the supply exists at the spur,change it to a socket.plug a radio in with the volume full blast,then go to bed,if you sleep well you aint got no supply
