Huge Electric bill, is it the immersion heater?

Hi, hoping someone can offer me some advise.

We have just been presented with a huge electricty bill increase from £31 to £165 a month, basically a £2k debt accrued in last 2 years as Southern Electric state we are on the highest rate of energy as we have the wrong meter, wrong heaters and wrong immersion for a 2 bed apartment! Property was built 2.5 years ago, with a HIP pack and everything else fitted is A rated energy efficient.

We have a Pulsacoil A class and there are 2 switches on the wall, but neither say on or off peak? one is blank with a light in (currently off at 10.45am) but no writing, the other says immersion heater and the light is on.

How do we tell which is the off peak switch pls?

We are not on an economy 7 meter, but a Single phase watt hour meter, and we know this needs to be changed to an Economy 7 meter and I think the pulsacoil is compatable? but our Dimplex wall heaters aren't as they arent storage heaters.

Would the immersion heater be the cause of such a large bill?
Can we be put on Economy 7 just for the immersion heater?

Any advise would be greatly appreciated please.

Thanks x

You have 2 heaters
Off peak is the bottom one
On peak is the top one.
If you have not got an E7 meter then you will be paying a lot.
Off peak is around half the price.
Any good sparky should be able to mark the switches for you.
If not remove the cover and switch one switch on and listen, you may hear which heater is heating up.
Be care of electrics though!

Many Thanks Mike.

Both the switches are next to each other so not sure which is which, but will see if can get the cover off and do as you have suggested.

Should we be turning the immersion heater off during the day when no one is home? or would it take to long to heat up again in the evening?

We do want to get an economy 7 meter fitted but this may take some time, so want to take any steps we can to save some pennies on teh bills in teh meantime.

Thanks

Leave it on.
As once heated it will go off.
Better to keep a thermal store hot.
Save water shower together?
Mike

Yes no hot water.
But is the unit hot?
Feel the pipes on top of the unit to see.
The ones which goes into the feed and expansion tank.
You can have a hot unit and no hot water!
If the unit is not hot then turn all switches on.
And if you have a boost button ( black)
Switch that on by pushing.
You should hear the unit start to heat up.
But until heated you will not get any hot water.
If not go to the home page where you can locate guys in various parts of the uk whom you can call out.
Or ring Gledhill,whom depending where you are may have an engineer or will give the name of one.
