New Storage Heater Installed - Electrician tells me it doesn't need to run on E7.

You can still get hold of the older style NSH's that do not require a dual supply. They are sold as reconditioned, which presumably gets round the restrictions on selling them as new. In reality, most of them seem to be new old wholesaler stock.

Unfortunately The P19 and P20 options are available for the SHF3000 not the SHS3000 I really appreciate the help. Such a pain that one model has it and another doesn't .

Are you absolutely sure?  The installation manual seems to be written for all the SHS, SHF and SHL variants.  Did you unlock the secret menu as described in Section 13 on page 18?  It may be easier to do it yourself if your electrician is not very clued up and not very interested.

Sounds like your download failed.  The earlier links generate a PDF of 172 pages, of which the first 29 are in English.  Have another go !

That was to be my suggestion - phone or E-mail SE directly and find out what they say.
My other suggestion would be to read you meter both night and morning to check that you are actually charging overnight on the off peak rate. Check and record both the peak and off peak registers - not just the total.
A 3kwh heater being charged for a full 7 hours = 21kwh and for eight would be 24kw. If your night rate is 6p then it's cost £1.44 for 24kwh and £6 if it were using peak rate at 25p/kwh which tend to indicate that the heater timer has been set incorrectly and is not actually tracking your E7 times, so you need to establish your off-peak times and ensure that you heater timer is set correctly. Do your recording in kwh rather than £££'s so you can accurately assess what you are using.

Sorry mis-communication, The heater only goes up to Parameter 18. Parameter 19&20 aren't showing up. I've emailed Stiebel-Eltron to see if there must be some other option to unlock it.

No need to contact the manufacturer!

If you actually read the user manual, it states that P15 needs to be set to 3 to use the internal clock.

I know you're trying to help me, but as I've said before, the manual you guys have got is not the one that is given with the heater, Parameter 15 on my Heater only allows me to change it to a LF signal, within P15 I only have the default option and the LF signal option, no 3rd option for internal timer. Sorry

The supplied heater is obviously not fit for purpose then!

I can find no evidence these radiators store any heat. Quite the reverse the manufacturer claims they don't need to store heat, this would be true knowing the German domestic heating market. If we in the UK had their TOU  we wouldn't need storage either. From stiebel-eltron advice to German domestic public.

2200-0300 Foreward Charge

0100-0600 Reverse Charge +OC=85%  savings compared to FC

0500-1000 OC

You didn't read as far as Section 3 of the manual then?

3. Appliance description

This appliance is designed to store electrically generated heat. The electrical heat is generated when the power supply utility enables the supply of cheaper off-peak power.

The times when this supply is enabled depend on the relevant power supply utility. The times when it is enabled are predomi- nantly at night.

Subject to the required room temperature, the stored heat is transferred to the room as hot air via a fan, and partially via the appliance surface.

I did not read any manual. I can find no evidence they store heat at all my friend. Your above post makes mention.that they claim they "store electrically generated heat". UK standard 9-16 brick heaters store up to +21kWh heat. These may, may not store enough for a candle worth. It's not the way Germans heat Thier home.

They IMO are unsuitable for UK standard E7, in the long distant past we had E18+ supply tariffs but not these days, indeed E10 is being phased out. They are merely on-demand 13a single 3kW element panel/convection (hence fan.assist) heaters worth £30 quid. Best of luck nice Englishman

3kW for 7 hours is 21kWh
