Can someone help me?: Elnur HHR storage

jadey2024

Thank you for your help. 😊 Yes the 7 kwh included one storage heater and the two panel heaters. Although the two panel heaters were only on a total of 3 hours which isn't a lot at all or enough so they will be on much longer from now on so it will be more than 7kwh usage at night in future. I'm going to keep tracking my readings for a week every morning and see how much it uses with the panel heaters being on longer so I have a good idea of my next bill estimat and what I can get away with.

Yes our panel heaters do look exactly like that one.

Yes, regular meter readings a good idea.
Main thing is getting the two Elnur storage heaters working correctly. It’ll be cheaper heat plus as heat rises, it will help with the bedrooms too.

Yesterday morning my night reading was 60899 and this morning it was 60906 with a difference of 7. Does that mean it used 7 kwh? 
The storage heater is 7 hours but it don't bring in the panel heaters then which used 3 hours during night. My panel heaters are 10000watts.

Yes, you used 7kWh of electricity overnight. Was that with the storage heater as well, or just the panel heaters?

Are the heaters like these?

If so, the full instructions are here (I know jadey2024 has a set but others night be interested):

It does seem it will run constantly. Which isn't practical at all. The 4 degrees lower is eco mode which is 18c. We are usually out most the day. So obviously waste putting them on them but all those programs by looks would need to run constantly on either eco or comfort. It's a huge silly flaw on these heaters if that's the case. I will email manufacturer just to see if that's definitely how they run or I can have them off during day.

I think the idea is that your house shouldn't cool by more than 4 deg C while they're in "eco" mode, so having them on then shouldn't use any electricity unless it's extremely cold. I know that my house, for example, only cools by 2-3 degrees overnight (even with the heating off) unless it's a severe winter.

So if I had the panel heaters set on one of the preset programs,  think there is a preset working hours program which might be ideal, then it won't be using electricity every hour of the day? Just wanted to clarify.

I have considered that too. Previously I got away with just 3 old storage heaters. Im trying to avoid using 2 storage heaters and 2 panel heaters on a lot as an extra heater being used then previously. I think it's going to be trial and error to see what best works over the following month. The other storage heater is on the landing, right at top of stairs, I'm top floor massionate and so my front door is downstairs, despite doubled glazed front door the stairs gets freezing although with using the 3 old storage heaters, one in each bedroom and one in living room, it heated whole flat sufficiently as was getting all day heat then from the 3 storage heaters, obviously now I'm only getting all day heat from one storage heater  and just late evenings from panel. Previously I had a convector heater on top of stairs, replaced with the 2nd storage but I never had to use it. Now that area is much colder. My only concern is the heat from storage will be lost down the stairs. It really is cold down there. They couldn't put the storage anywhere else on landing either. I have asked if I can put a door curtain to be put up which landlady has agreed so might help with the draft coming up the stairs and on to landing.

Ok, so now there’s more heaters than before but less effective.
Shame that Elnurs weren’t installed all round to replace the old storage heaters.
Stairwells and landings can be tricky to heat, especially with electric.

I do wish they had put 3 storage heaters in just to replace the others. To me it would have made more sense because worked well last time and with the enurs being smart ones, it still would have saved me money than before on the old ones. I just feel this new set up on this gov grant is not going to be as good in heating flat all round or saving me extra money. But I will have to see

Yes.

Imagine you set your panel leaters so the "comfort" temperature is 20C and the "eco" is 16C. When you get to the end of a "comfort" period, the room and all its contents will be at or near 20C. It will take a while for the room to lose enough heat to cool down to 16C; I don't know exactly how your maisonette will cool down but my house would take several hours to cool down that much.

While the room is cooling down, the heater won't produce any heat and won't use any electricity. Only when the temperature drops to 16C will it switch back on.

At the end of the "eco" period the heater will switch back to "comfort" and turn on for long enough to bring the room back up to 20C. It might run continuously for an hour or more but once the room is warm it will switch on and off to maintain that temperature.

I can't say exactly how you want to program your panel heaters (it will depend on part on when your E7 hours are, and what your routine is) but, for example:

• a period of "comfort" from 6am (so you make use of the last of the E7 hours) to 8am to have a warm room to wake up to;
• then another period of "comfort" in the evenings before bedtime.

Between these periods the heater in "eco" mode will just keep your rooms above 16C, enough that you shouldn't feel cold wearing warm indoor clothes (16C always was the minimum legal temperature for shops and offices).

The storage heater in the living room should keep the core of your house warm and will help reduce heat loss from the bedrooms, assuming a conventional layout where they share walls.

Thank you so much for explaining it to me. It has helped a lot. I will set my own program them for it to come on like you said at end of your reply. Hopefully that will do the job. If not I can tweak it if need be.

I still haven't set the program but I feel for my daughters room these are a major bad idea having panel heaters. I had always had the storage heater running in her room when she had it from Nov-end Feb so we never realised how cold her room got. She was away for the weekend and I got a thermometer in her room on Saturday for the first time. It was down to 14 degrees during the day and at 13 late at night. 😔 Whereas in my room it is consistently around 16.5 and at worse slightly under 15 so much warmer. So I can get away with putting my panel heater on occasionally as don't mind sleeping in 16 degrees. But for my daughter 13/14 is very low and when I put her panel heater on an hour or 2 within 2 hours of it being off it's down down to 15 almost 14 degree again. She is in there from mostly 4pm onwards (typical teen likes her bedroom) so I'd need the panel running really every 2 or so hours I believe from the evening until morning ? We find having it at 18c is good to set it at as any more gets too stuffy as a small room, so plus side it heats up quickly but just cools down as fast. She gets more condensation on her window on the odd morning now when it has been very cold outside unlike before on storage heater. I do open her window in the morning but you literally couldn't see out of it this morning for it as fully covered rather than just bottom. They are new double glazed windows. Her room has two external walls so guess it gets the cold more whereas mine is sandwiched between 3 internal walls. I'm just not sure how I could program the panel with such low temperatures (and that's now so dread to think how cold it get later on in winter) Would I need to program it so eco is 14 degrees and 18 when she's a home? It just means I will have to run it more on day rates then originally planned so couple hours in evening, then 2 hours before bed then 2 hours before she wakes up😔 

The one storage heater is using about 3-4 khw a night from checking my meter which is pretty good so two would be about 6-8 a night together so think it cheaper and better she had a storage heater but don't know if my landlady would be up for it.
