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

My whole input over the decade on German 'snake oil heater' use in UK domestic environment has been about their unsuitability for UK TOU:

- insulation standards
- 24/24 operation
- zero storage/release
- convector camouflaged as NSH

Our standard with three 3kW elements will heat home 7 hours overnight then continue to heat home at two kW for the 17 hours they are switched off. Ours are designed/specified for UK TOU tariffs. Euro/German are designed/specified for totally different TOU/insulation standards. They are not suitable for UK domestic heating.

This thread like all (see Fischer/wiebo etal) threads over the decade are free opinion forum debate not 'argument'. Please feel free continue to post opinions/debate in a polite MSE way.

I think that you should read the specification e.g. Heat output per hour - 1.2kw

You can't compare Fischer panel heaters running on expensive daytime electricity with Stiebel Eltron storage heaters on E7.  Their only serious drawback appears to be the inability to work with split E7 night rate hours if the internal clock is used.

Please stop trolling.

You write, it stays in the ether. Be nice to people, this is MSE.

smith1932 said: OP has done this,  has said that this version of the heater doesn't have Parameters 19&20 so can not set a manual charge time.

But did you first set Parameter 15, i.e. so that the charging is clock controlled?  Parameters 19 & 20 are probably hidden unless Parameter 15 = 3.

Even though the OP states that they have read the manual 100 times, I still think that this a simple case of RTFM and operator error.

I do not believe that the OP has a "different model" that lacks the ability to program charge times.

The OP has said nothing about what settings they have programmed in the configuration menu for timer settings e.g. Pro1 etc?
 
"To use timer mode, select the required time program in
the standard menu (see chapter "Settings with integral
room temperature controller / Standard menu")."

"Ensure the day of the week and the time are set correctly
when setting the time programs. "

OP should read pages 8,9 as my guess is still operator error.


Stiebel Eltron SHS 3000 HHR High Heat Retention Storage Heaters

"Functionality

The 7 day timer allows you to customise your heating to suit your specifications. The storage heater is able to match your lifestyle schedule, and with the high heat retention, stores energy efficiently until when you need it most.

With the aid of the integral controller, the room temperature can be quickly altered and controlled effectively. The optional boost functions offer immediate interactive heating, improving comfort and performance."

I think the bit you've quoted is about setting the output of the heater.

The OP's problem is setting the time during which it charges to match the cheaper night rate on his electricity tariff.

Agreed but the OP has not stated exactly what they have set up for the various parameters and I'm not convinced that they understand all of the settings.

It makes absolutely no sense that their Stiebel Eltron SHS 3000 HHR is different from the published manual.

richie - if you bothered to read the info you be aware that these are not Fischer or any other magic heaters - they are proper storage heaters equipped with a big pile of bricks and three 3kw heating elements which can be configured to suit various E7  wiring scenarios including a separate contactor switched e7, control circuit switched using an auxiliary module and internally switched using the inbuilt clock. 
TBH your long winded explanation didn't really clarify the issue and bringing in Fischer and their ilk is just a red herring to confuse

Its unclear whether they've been installed and configured incorrectly or if the OP has had a panic attack by looking at a smar meter IHD when they've been turned on for the first time. That why we've requested kwh figures from the meter and config info from the programmer. Alternatively he should get the installer back to explain how it's set up and how to use it properly

Gerry1 - for how many people in the UK is this an issue ?   I think only one of the old distribution companies out of the 12

I think Richie has so confused the OP that he's gone home and left the rest of us to argue about it

IF .. .. its the case that they have 13 bricks and three heating [21kWh storage] elements, I will apologise profusely to you my friend. Can you link me to the info that you have quoted please.

matelodave

Yes - look at the link that I put on page one of this long and tortuous thread (I could refer to the thread by it ref number if the forum update hadn't deleted the function)

there you go to save you the effort of looking for it - https://www.stiebel-eltron.co.uk/content/dam/ste/cdbassets/current/bedienungs-_u_installationsanleitungen/SHF_2000-7000___SHS_1200-4800___SHL_3500-5000__8225d680-7a8e-4d6d-bba7-1e05abdb7d6c.pdf

In the above link, page 12

10.1 Function
The storage blocks are heated via the heating elements between
the rows of storage blocks. The charge can be adjusted with the
charge controller.

Along with a pretty diagram of bricks.
