economy 7 on prepaid meter for a 1.6kw heater Does this sound correct?

The power usage dropped over the four days mentioned. this time he used the main hhr40 plus another small storage heater on his landing upstairs and his portable fan blower heater occasionally over this time. The daily extra cost of electric went from £5 to £3 to £3 to £2. so its demand for power is definitely coming down.
The mid room temp raised a little each day, but dropped each morning to 13 - 14 degrees when the neighbour woke up. I have re programmed the timings and raised the st value to 90% overnight heat charge from the default 80%. This should prevent the balancing element kicking in during peak times.
I spoke with Elnur. They advised me that if a problem existed with the unit, an error code would show when displaying the current status information. He said the unit may be under powered for the size of room (4.5M x 4.5M) considering the thick walls and drafts. But was advised mainly to run the heater ahead of the when frost sets in.

...considering the thick walls and drafts

To state the obvious, sorting out drafts can significantly improve the feel as well as reducing costs.

Depending on the source, a bit of dedication with a tube of sealant could work wonders.

At one stage the neighbour was only heating one room - the biggest heat losses could therefore likely been through open door to the rest of the inside of house - when going in/out of the room - and even when door closed when in it.

Some people don't like sitting with their inner doors fully closed - even in winter.

Others do - and invest in thermal door curtains and a door draught excluder where other rooms are kept deliberately colder to save money.

I use them at external door - its old, part - single- glazed, but not particularly drafty - as has draft excluder all around - it did have a 6" gap at mortice lever lock stike plate - I patched that last winter - and fitted a letter box cover (which had a flap and 2 rows of brushes - took it off as snarling mail by spring) - yet to replace it. Added a thermal curtain instead this autumn - to isolate a bit of any loss - from rest of hallway.

Many drafts come from sources that are meant to open and close - doors and windows.

So yes - definitely worth trying to address those - using rubber or foam seals if hasn't already.

And if the building seals around the windows or door frames etc are bad - then by all means - seal them.

All assuming able (young enough, healthy enough and owner not tennant(*)).

(*) Many LHA's installed these modern panels - without really explaining their usage and settings - often to elderly tennants in smaller all electric properties.

And remember - all homes need some fresh air - so cannot be too over zealous re-light drafts.  Even in winter - my window vents are left open - to circulate a little fresh air.

Passive thermal homes - end up using fancy heat exhangers to do the same.
