Only been in for a couple of weeks, but I was hopeful when I checked our consumption for February that it might be a bit lower than January.
No such luck.
Our overnight consumption is up by a third. The only difference to usage overnight is the new heaters.
Everything else is as before....absolutely.
We are all electric, and our December bill was £195, so we looked at trying to save.
The ancient 'inefficient' heaters worked fine...they only used cheaper Economy 7 power to store heat, and then cost nothing all day to release the heat. We were only persuaded to change them to 'save electricity'.
Now, these new heaters store heat overnight, but use fans during the day to come on and off as they see fit. Instead of the stored heat bleeding out all the time, the fans are on and off as the eco programme dictates. We are home all day, both 75 plus, and we are on the preset eco setting of 21 in the day, 18 at night.
The room is just about tolerable. With the old heaters I was in shirtsleeves all day. Now I'm in a sweater.
No way am I going to tolerate using more electricity to be colder during the day.
I know it's early days, but I don't have a good feeling about this change.
And reading the other comments, I think there's more to this.
Do let me know how it goes.
My initial mail to Elnur got only the standard blah-blah response. I shall check my usage, as I do every month, at the end of March, and take things from there.
Have you as yet reached any resolution to your problem?
We have what looks like the same complaint.
We were persuaded to replace 17 year old Creda night storage heaters with Elnur Gabarron heaters, ECHHR20 and 40.
Although they have only been fitted for a couple of weeks, our February Economy 7 usage is up 30% on January, the only change being the new night storage heaters.
We have ended up with a colder house and what threatens to be even bigger electricity consumption.
As for that 40 watt fan used in the daytime in modern storage heaters - exactly 40 watts of heat energy is given off so it is not wasted. The only issue is that it will be using peak electricity tariff, but unit for unit, will not cause you to use more energy to attain the same room temperature.
The problems that make storage heaters cost more or less to run are all down to having the correct size and how they are programmed and used, all of which is down to the user and not the science of energy efficiency.
The main factors in getting the best out of storage heaters are:
1. Sizing correctly for the room. Too small and they will need to supplement heat with the daytime tariff. Too large and you will be wasting money on buying an oversized heater.
2. Correct overnight charging. Put too much overnight charge in and that will seep away overnight when you don't require heating, wasting energy. Put too little in and you will need daytime tariff to make up the shortfall. This is the biggest factor and is generally easier to get right on modern storage heaters as they have some logic built in to help optimise this.
Modern storage heaters have better insulation, so overnight charging losses should be less than older heaters.
Regardless of the above factors, you are still getting 100% of the electrical energy turned to heat regardless of what model / brand / age of electrical heater you buy, the difference is that you might be getting that heat energy at the wrong time of the day and/or using the higher priced tariff.
Concentrate your efforts on optimising the overnight storage settings to get the best out of electrical storage heaters.

These modern ones do not have as much storage facility, so use daytime units to keep the house warm (rather than slowly releasing what they have stored overnight).
This is why they are considerably more expensive to run as you have found out.
There is no solution, other than ripping them out and replacing them with proper 'storage' heaters.
We have excactly the same scenario, and I suspect with the same well know company. Since having our old system 'upgraded' (!) we have been hemorrhaging cash to our electric provider. Actually contemplating a disconnection and moving towards something far less complicated.
Posting as we're thinking of changing some of our 40 year old NSHs with these new Lot 20 heaters
