Problems with HHR storage heaters

babyshinobi

Hi

I have recently had my meter changed to economy 7 tariff and had high heat retention storage heaters (Elnur) installed. The digital display only comes on during off peak house (after midnight) and during the day this is off so the thermostat and setting controls cannot be used.
I have tried to charge the heat up when it is on at night but have not been able to do this either. Do these heaters also need to be getting peak power? It is not as simple as the manual storage heaters where you can put the dials at a certain input and output setting and leave it. I'm afraid I am very confused by this, any advice would be appreciated.

Thanks

A quick shufti at the operating instructions shows that they've got an inbuilt convector heater and electronic controller which suggests that they need a permanent supply as well as the off peak supply to operate properly.

Here are the installation instructions which show two supplies - the restricted (off peak) and 24 hour supply (wiring digaram at the end of the document) https://www.elnur.co.uk/wp-content/uploads/2018/05/15190016-R3-ECOSSH_UK.pdf. You need to get a separate supply run to each each heater which isn't controlled by the off-peak supply.

What sort of supply did you have before E7 was installed? What sort of heating did the HHR heaters replace? Did you have storage heaters previously which were controlled by the supply.

I've never quite worked out how putting an underpowered storage heater with a boost heater (balancing heater?) which needs peak rate energy to operate makes it more efficient - having to use a peak rate heater to maintain the temperature just seems counter intuitive to me
