Doing per hot tap needs more than 1 setup it needs to be done for every hot feed. Like other hot taps. Could include dishwasher, washing machine if they take a hot feed (less common these days)

I've a plumber coming to look at removing some gin barrel piping so I'll ask him about the valve for the cylinder

Hi,

New to all this so forgive me if it’s a stupid question!

We’re looking at putting in PV panels, battery & an EDDI. One of the installers we spoke to wasn’t in favour of fitting an EDDI to our traditional copper water cylinder. He said we’d be far better off getting a new stainless steel tank.

We’ve asked around & it seems like supply & fitting of a new (larger) tank would be about €1600. We hadn’t budgeted for this, so we’re wondering if it would be ok to go ahead and get the EDDI fitted to our existing tank & then maybe in a year or 2 get the new tank. Any thoughts?!

so the eddi isnt fitted to your tank.. its basically a device which sits between your immersion switch and the immersion and it can send excess solar to the immersion to power it, or you can use it as a timer device with app control to boost the immersion at certain times.. we had a 90 litre copper cylinder and found that it wasnt heating very well with either our gas or immersion/eddi so we had it replaced for a 120 litre pre insulated tank. Cost was about 850 euro. Bigger tanks im sure cost more.. so the question for your existing setup is probably more - is your immersion working properly now? and does your tank fully heat up with your central heating system? if so there's no reason the eddi wouldnt work - you can have issues with immersion in general heating a larger tank of water which if you read this thread you'll get some sense of

AmpMan · 30-06-2023 1:49pm

@fishy Did he want you to get a bigger tank maybe ? No reason your copper tank couldn't be used if its sound.

Fit the eddi and upgrade the tank at a later date.

Thanks so much for explaining this! Yes, immersion works very well at the moment. In fact the water coming from the tap is often too hot! We can also heat our water via mains gas central heating & that also works very well.

Thank you! I think he just felt that the water might not heat up very well? As per my reply above, it does!

So, we should be ok to just get the EDDI installed with our current setup & then maybe down the line change to a better tank if we need to. Thank you!

Do you use the hot water tank now? If not, scrap the Eddi. Cheaper to use night rate electricity on the immersion and get paid FIT of ~20c per unit you don't use.

As in the Eddi won't pay for itself. But it has a great convenience factor of hit water when needed. Read back on this thread so see Eddi owners say that.

Yes - is answer to your OP. Old tank will be fine but losses heat more than newer well insulated ones. And can always change the tank in time. We scrapped getting the Eddi for reasons I mentioned here.

We have a day/night meter & heat the water for about 45 minutes early in the morning. Immersion has been a cheaper option for us since we moved to Energia & got a good rate from them last September. Obviously we probably won’t get such a good rate when we start shopping around on renewal date.

I suppose we’re just trying to future proof things by getting the EDDI fitted from Day 1.

We did the same.. added it for completness.. we ended up buying it ourselves via the uk cheaper when the currency was in our favour and our installer put in as part of the job... its a convenience thing really... i dont really care if it pays for itself... i probably should!

keith_d99 · 03-07-2023 8:17pm

Hi all - got a 2nd Harvi installed today to monitor Solar PV and just checking whether it is installed correctly

... From what I can see when the panels aren't producing much at all ... the Harvi seems to lose power and the icon disappears from the app. The Harvi then has a question mark next to it on the Eddi ... indicating connection lost.

Is this normal/expected behaviour or has the clamp been put in the wrong place?

jkforde · 04-07-2023 4:03pm

some have hooked it up to a battery to avoid this scenario happening since the harvi is designed to harvest the required watts to operate from the L cable (typically)

keith_d99 · 04-07-2023 10:11pm

Not sure it’s a supply issue … when the panels are in full flow it’s still dropping the connection to the Eddi.

graememk · 04-07-2023 10:38pm

https://www.boards.ie/discussion/comment/120806502#Comment_120806502

Could be a wireless signal issue then.

I have removed the Harvi from the Eddi ... and tried to re-pair.

When I press the button on the Harvi, it will flash blue to indicate the channel number. But it won't flash red to indicate pairing mode. It may not have enough power to go into pairing mode? (The panels are only generating about 0.5 kwh at the moment). Before I un-paired the Harvi only connects when there is a LOT of power coming from the panels. I thought the Harvi only needed 200w+?

Checking the installation ... the clamp cable is wired into the invertors AC supply - is that correct?! (photo below ... apologies boards put it sideways! 😀)

olympicweights · 13-07-2023 10:20am

My eddi seems to be hanging a lot lately. I check it regularly and sometimes the unit will have the green light on or maybe one of the blue lights but the buttons won't work and the unit seems to be hung. If I turn off the switch and back on it works correctly but lately it hung again within a few hours. Any one else experiencing a similar issue?

pandabat · 17-07-2023 8:07am

Happened me twice in 2 days a few weeks back. Firmware was fairly old 4.x iirc so I went through the upgrade process for that and it hasn't hung since afaik

... However, tank ran cold this morning after it should have been a scheduled boost yesterday (smart tariff free Sunday electricity) and it looks like the Eddi just ignored the schedule once it hit the first "tank at max temp" and then never resumed. Looks from graph that it worked ok last week but might check for further firmware update just in case.

17-07-2023 6:25pm

The Mienergie app just stopped working for me today. Anyone else having issues with it?

This is all I get:

The device itself states that it is connected to WiFi. Power cycling made no odds.

Moreilly · 17-07-2023 6:50pm

Same here.....

Jonathan · 17-07-2023 7:23pm

Should be resolved now. There were issues with myenergi servers from approx 17:45 to 19:59.

Yes, now resolved

topdecko · 30-07-2023 10:27pm

Is it worth getting myenergi app. Have solar set up now for a month or so and used to Solis app.

Just realised there is one for the Eddi in the hotpress. Has been working fine although I think it drains the battery during day. ie consumption in house increased since battery installed and it seems to be eddi driving it when no other appliances on. I want to tweak settings but I cannot seem to connect to the device from the app as no reg number or SN on device.

Also WiFi won't connect/ no access point name visible etc. May already have been set up by installer???

Thanks for any advice

pandabat · 02-08-2023 7:02pm

The MyEnergi app is certainly well worth looking at to get visibility and control of Eddi/Zappi.

I'm presuming you can see the SN somewhere in the on-screen menus on the Eddi (though haven't checked this). You can manage a lot of the settings from there too but the app is probably a handier, more user-friendly means of doing it.

Will give you generation, usage and export figures and probably others depending on what else you have in your setup (e.g. Zappi).

DC999 · 03-08-2023 7:11pm

Try the Myenergi web login on a computer. I find it easier to read than the mobile app.

Guybrush Threepwood · 07-08-2023 7:57am

We just got solar panels and Eddi on Friday and today I woke up to “Max Temp Reached” but no hot water. Even the Myenergi app shows 0kwh for both tanks. Can anyone help me in plain English? The technical talk on the troubleshooting pages are only confusing me more. I’m not very savvy with this stuff and we’re only new into our house so don’t know much about the boiler. We’ve an oil boiler if that helps?

See that black thing on top of the immersion,

There is a button in that, an over temperature trip, press that in.

If it keeps happening, more investigation is needed(thermostat gone in immersion, or set too high)

Just keep an eye on it, as that shouldn't be tripping on a regular basis. That is a fail safe on the immersion.

If it does, it is likely the normal thermostat on the immersion has failed, and depending on the immersion it can be replaceable. Some need a whole new immersion

(Immersions in Ireland are generally rarely used, until they get an eddi!)

micks_address · 07-08-2023 7:43pm

Hi folks,

Thinking of adding the relay board.tp my Eddi..can you add two temp sensors if you only have one immersion? I was hoping to put one sensor at the bottom of the tank and one at the top

Cheers,

Mick

roshje · 07-08-2023 8:33pm

Anyone any idea why my Eddi, temperature set at 60 degrees but will trickle feed it sometimes up as far as 68 degrees?

Ha Long Bay · 07-08-2023 8:47pm

https://www.boards.ie/discussion/comment/120950341#Comment_120950341

The relay board supports two temp sensors using PT1000 sensors. Where you are able to put them to get accurate readings will depend on your tank setup.

As the bottom sensor in my setup is below the immersion it provides no data for PV diverted data but is useful for information heating via gas.

micks_address · 08-08-2023 6:34am

https://www.boards.ie/discussion/comment/120950582#Comment_120950582

Thanks - you dont need to do anything different to use the two sensors on one tank? in config/wiring?

DavyD_83 · 08-08-2023 10:13am

Hi guys, still getting to grips with my new solar install and how it all outdated.

I've figured out based on the info here that my Eddi is currently set up as

Tank1 -bath

Tank 2- sink

System was set by installer to prioritise Tank1 -bath; wondering is this standard and recommended?

I was told it will heat first tank, then switch over to second.

I keep twisting the logic in my head and can make either make sense, but my instinctive logic was that it should be sink (which it would have been pre-solar), so that it will heat less water fully, before it considers heading full tank.

Also, I don't think "overflowing" power from bath to sink makes sense, as full tank would already be hot. Installer said, "yeh, but then you only need the smaller element to keep it hot".

I have an electric shower, so at the moment this water is only being used in tattoos around the house, I really don't need a lot of hot water on daily basis.

I've also considered discount the bath tank for now

micks_address · 08-08-2023 10:17am

when mine was installed i had a sink/bath immersion.. installers logic was to only wire up bath as the sink can trick the thermostat into thinking the cylinder is fully heated and you never get a full tank of water. Not sure about that. Anyway i had a new cylinder installed few months ago which just has one long immersion so its wired to the 'bath' thank 1 on the eddi

DavyD_83 · 08-08-2023 1:02pm

Cheers. I think that makes sense.

At the moment, I don't really need it want a Full tank heated, so think it makes sense to stock with 'sink' where possible, and also to heat at 1.9kw instead of 3

slave1 · 08-08-2023 4:46pm

Sink 1st priority and then Bath, as sink heats the top of the tank quicker which is where your hot water is drawn from.

Is temp cut off not determined by temp stat on your immersion element, this has nothing to do with any setting on your EDDI

pandabat · 08-08-2023 6:33pm

https://www.boards.ie/discussion/comment/120948305#Comment_120948305

There are some issues with V5 firmware and scheduled boosts btw (I'm running v5.178, which is latest afaik). How it presents on my own setup is that the scheduled boost starts, a "max temp reached" is shown a small while later (although it's unlikely that the tank had actually reached max temp in this timeframe) and the scheduled boost stops. The scheduled boost will NOT restart after this has occurred although it will recommence if the Eddi is turned off and back on again although the original problem will most likely recur.

The issue doesn't seem to affect normal solar divert outside of scheduled boost windows and so I missed the issue for a few weeks after first upgrading as the weather (back then, before July) was good enough that we had enough hot water purely from solar. However once we slid into the iffy July weather then the issue became noticeable as we then need the scheduled boost.

Check your firmware to see if you're on v5.xxx firmware and keep an eye on what's going on with your setup via the MyEnergi app/web-portal.

There are a few threads about this on the MyEnergi forum.

Ha Long Bay · 08-08-2023 7:02pm

https://www.boards.ie/discussion/comment/120951297#Comment_120951297

The relay board has two temp connections PT1 and PT2.

In Home Assistant both are available to read data from.

In the Myenergi app it seems to only display data from PT1 though.

I've also started messing with temperature on eddi after installing sensor board and pt1000. Went from 60 to 63 bit can't see any difference yet (cylinder thermostats are both at 70degrees for now

micks_address · 14-08-2023 5:03pm

Hi folks,

Fitted the relay board and two temp sensors to Eddi today.. I'm seeing quite a disparity between the top and bottom of the tank..Maybe I've the sensor to low on the tank?
