Elnur Gabarron Heaters

Chantsquad

Thanks for your post. That is really useful. Also i managed to find the installation manual where it tells you how to adjust the balancing element settings as there is no mention of this in the other operating instruction manual. I have made the same adjustments as yourself & hopefully this will make a big difference. Thanks again

Set the heaters using the installation manual first (reset to default then you know your starting fresh), then work through the user manual to program how you want them to work.

I confirm adjusting the balancing element setting and adjusting the overheat setting has made a noticeable reduction in kWh used in the evenings at peak rate therefore much reduced costs.  

Since making the change my total usage has reduced to even less than the 15 year old Credas without feeling any less colder.  The weather has also been much colder the last couple of days compared to when mine were installed three weeks ago and not programmed for my liking.

I asked Elnur in a further email, if the initial charge setting was worth changing from the default ST80 to 90 or 100. Elnur replied…. 

Your heater can take a full charge within the 7hour period and can be changed from 80 to 90-100. It depends on what the heat loss is in your room that the heater is in which is why it might be using your balancing element. 
Have you noticed a red dot in the bottom right-hand corner of the screen when the fan is on? This will indicate the balancing element is on, which is on your more expensive rate, and this is used to help give a boost to your room.

Hello,

This is my first post! I had two Elnur Gabarron heaters installed in my studio flat in April 2023 as part of a government-funded scheme (should I mention its name?). The heaters are an ECOHHR40 in the living room and an ECOHHR20 in the hallway, on Economy 7. I usually work from home.

I’m grateful to previous posters who pointed to the installation and user manual for the general settings (in my copy, section 3.8). I’d like to offer some experiences after experimenting for some while.

I only made light use of the heater to begin with as it was spring, but I found that with the default P06 (max hours for balancing element) of 5, this element was being used for several hours a day whereas the main element was not charging very much overnight, resulted in more kWh for daytime usage than expected.

I then tried setting P06 to 0 (and also increasing P07), as suggested on this thread, but that led to excessive charging at night. So, I got in touch with Elnur UK technical support, who have been polite and responsive throughout.

Specifically about setting P06=0, I was advised that this is not recommended as it turns off the smart function (e.g., automatic adjustments for comfort based on temperature sensor readings), so their initial suggestion was to change PO6 to 1 which still keeps the smart function enabled whilst using the minimum on the balancing element.

So, I have set P06 to 1 and during the day I adjust the daytime (‘sun’) temperature, e.g., reducing it when going out. The meter readings consistently show that the proportion of night to daytime usage increasing, as expected. I have found that this arrangement generally works well for my needs; the heat retention is very good, usually with sufficient capacity in the evenings without having to introduce additional heating.

The main limitation in design (in my view) is the way that the heater deals with sudden drops in temperature. The percentage of the main charge stored, as indicated by the reading Stnn (nn a two digit number), only seems to increase/decrease by 10% per day. Assuming this is the case, it’s left to the balancing element to compensate. This is what Elnur UK said:

Of course there are going to be days where the weather has a sudden drop in temperature and that is what the balance element is used for and why it is really defaulted at 5 as 1 or 2 may not be enough as the heater can only monitor what’s going on for that day it takes its charge according to that.

I have actually kept the setting at 1 and with a sudden drop have found that it does mean a bit of shortfall for one or two evenings. On these occasions, I have the option of a portable oil-filled radiator. But I think a better solution would be for the smart function to allow the 'St' amount to be increased/decreased in larger steps at each overnight charge.

Overall, the new heater serves me well and is definitely a significant improvement on the 40+ year old Creda I had before. I estimate the costs are comparable with the old heater, but the main difference is the heat retained in the evenings. Just to add that I typically set my ‘sun’ temperature to around 18 or 19 degrees C, which may be lower than average.

I have the elnur garbonn heaters brand new last year what an error of judgment that was! Previously had normal nightstorage heaters which were brilliant and only used cheaper night rate electricity. These new things use both day and night electricity and are costing me about £8 a day, and I'm cold when I come home from work. I have spoken to elnur who said lounge heater probably undersized. I did originally purchased the bigger one but it was huge so sent back and ordered 2kw same as before. Elnur told me to go into setting para UPO8 and put it to 0 this stops it taking day rate electricity. As for working like an old nightstorage it's not as good still cold but not skint and cold. I'll get a little fan heater and put on for a couple of hours. Will have to get a loan to put in Gas central heating at least I'll be warm next year. As for an electric car no chance! Got in this afternoon only used £2.60 in electric now,  I don't use the oven and only do washing in cheap rate time, also only turn water tank on once a week, so these weren't costing anything. Good luck anyone who has these, I wished I'd saved the £1000 + and just borrowed the rest to get central heating.

I have recently had ECOHHR heaters installed and have experimented on how to use them. Have I got it right that once the heat is stored on the economy setting the only way I can stop the heat from blasting out at 7.30am is to set the comfort temperature really low so not much heat is released. I need an idiots guide on how these heaters work not just the operating instructions that are given.

Hi, have there been any revelations regarding these heaters since the last posts? I too have some installed through the Gov scheme.  I think the hardware seems sound, holding heat for much longer than the old ones.  Yes its expensive in winter but that's because electricity is still expensive compared to Gas.
My very major issue is what chezpt above discussed.  The so-called smart function is not fit for purpose. The only way to reset the charge period back to the 80% is to do a factory reset.  If left to its own devices, every night it charges 10% less so that every evening it is having to use extra power to heat the room.  This extra power costs 3 times as much and doesn't really heat that well, resulting in every evening the rooms getting that little bit colder.  I have reduced the max top-up charge from 5 to 1 to try and reduce costs but this doesn't help with increasingly cold rooms.  
I am currently resting the urge to do a factory reset to see if eventually, the charge % starts going back up.

All it needs is an override to reset the % charge back to 80% without a full factory reset -  
why was this not included, it just seems stupid

I am very tempted to just try and sell these and make up the difference and get something like the Dimplex Quantum heaters.  That seems like such a waste of Gov money to me

In March 2022 I had replaced under the government grant 3 Dimplex Storage heaters with 2 Elnur Gabarron heaters. One ECOHHR30 and one ECOHHR20. I was perfectly happy with the old units although they were over 20 years old and having a mechanical control I could regulate the heat as required. Having these new MODERN units fitted was a BIG mistake. Not only am I using the same amount in Kwh for the HHR30 as I was for 2 of the older units but I am on a dedicated E7 line. By that I mean there is no electric power to the units outside of the E7 hours, and so, if I am understanding DP70sgal (11-Mar) comment correctly the fans are not able to operate during the day to release the stored heat. The units remain hot but the heat doesn't get to heat the rooms and I am left to supplement with convector heaters during the evening. I intend to contact Elnur to get a better understanding on this. If it is the case that a 24 hours supply was required for these units then I should not have been offered these units in the first place.

Did you ever get this resolved?  It seems as though the exact same thing has happened to me.  I have just had the heaters installed under the government grant a few days ago and similarly it seems as though they have only been connected to the off peak supply.

This is a great thread thanks everyone. 
I have had 3 of these installed to replace electric oil filled. We never used them and just used our log burner. 

It seems the key with these is disabling the balancing element (po6) which I will try tomorrow.
I have the main supply connected and the loop to the restricted 'e7' supply. 

I'm not on e7 but I'm on octopus agile and solar so sometimes need to charge these in the day or night for use in the evening when we are home.

I'm going to remove the loop and fit a 30amp zigbee/wifi switch to the restricted side. I'm not sure if p01-p04 will affect this or what to set to?

Any advice appreciated.
TIA.

Ok so set P01 to 00:00 and P02 to 11:30.

Not sure if i can lose that half an hour by overlapping with P03 and P04 but this is cool for a test.

Zigbee relay fitted and tested.

It monitors power as well so i can see whats going through it.

Other settngs as in my last post.

Noon (minimum) set to 5 degrees.

Sun set to 25 degrees

Core temp 17

 Time 13:20

Heating Output on noon

Power in 1.6kw

Well it seems to be going in!

I will update later

So I stopped at 4pm.
It got cloudy so the Solar stopped giving and the price per kwh went from 5p to 27p.

Core temp ended at 97.

Not turned it on yet as it's still warm in the house!
