Can you use this to switch on swimming pool heating and the pump
@@eopoep (late response) my knowledge of ''dimmer switches'' (which this simply said is, but automated) is that you can easily dim the heater for your swimming pool, but not the pump. the pump requires a certain amount of amperage that its set up for, but you can control the heater (which consumes most power) but not the pump.
@@wildwilco cheers. Sounds like having three panels are three pumps could work. More Solar = More Heat and More Pumping.
@@eopoep more panels = more heat, but you'll still need a solid constant stable power supply for pump. It's probably made for a certain RPM, and is not really modular (most pool/aquarium pumps arent) in speed. So connect the pump to the grid, and the heater to EDDI
I've got an Eddi and use it as described to heat water from my solar PV from spring to autumn, allowing me to turn my gas boiler off for half of the year. I'm intending to invest in a home battery and will also be getting an EV next year. So my hope is that on sunny days I'll be able to charge my car; heat my water and use whatever energy is left to charge my home battery. I reckon this will minimise both the amount of energy I draw from the grid and the amount I send back, reducing my energy costs and my carbon footprint. A win-win!
Love the myenergi products, we have them all! The support and backup is excellent too. An example of a great UK company.
Just had one of these installed. I have 2 x Solar systems. A legacy solar system (came with the house, 16 panels), and a spanking new one (38 panels). The Eddi can handle both (2 x harvi sensors), and manage hot water based on a surplus of power measured against the combined output of both (separate) solar systems.. rather impressed.! I also have a 19kwh battery - Eddi allows battery to be prioritised before taking power to heat water - another excellent feature... really good product.
@Sune Wallentin Goettleri run lots of computers at home , and also have to cool them.. power hungry... :)
I’m having a similar set up. Would like your thoughts. 38 panels(13.68kwh), with 25kwh battery. Eddi to hot water cylinder which will service both the UFH and usable hot water. Unlikely I will have enough excess solar to heat the tank fully, in which case the gas boiler will do the work. Debating whether it’d be simpler to separate the two, having the UFH connected directly to the gas boiler, and eddi to cylinder for usable hot water.
ABSOLUTELY love the work by the FullyCharged team. Please keep up the fantastic content!
I love the products for the home that I am seeing here. I would like those featured to be asked if and when their products will be made available outside of the UK. I live in the USA and I am sure many others in the EU would be interested as well. Thanks and great show!
I'd be really interested to see this in the US. I spoke to Jordan at Fully Charged USA about this product. I hope it will be available soon.
I am looking at getting one of these but I can’t see how they can lead to any savings? My off-peak go tariff is 7.5p kWh. My gas is 7p kWh. So if I was to heat my hot water cylinder up at 00:30-04:30 it would cost me extra to do so. Likewise, if I divert my excess solar to an Eddi, I will save 7p kWh gas but as I am on the a SEG tariff I will not be getting the 4p kWh for exporting the excess solar. So I am really only saving 3p kWh. At £500 supplied and fitted that is a lot of 3p’s to see a return. It might have worked great with FIT payments but not now, Or am I missing something?
What we need is something which understands not just your car's state of charge and the temperature of your hot water, but the state of your household battery and your tou tariff and can use off peak electricity as well as excess solar.
I would have liked a deeper dive into the hub, the app, the web portal and the Eddi add-on board and what they can all do. And a hint about the new product we know they are working on. Perhaps it will be unveiled at Fully Charged Live.
I have been enjoyed, so thank you for delivering.
I'd really like to see more, such as step-by-step for solar, battery and car.
Just had a Zappi installed and I am looking to integrate it with my battery/ solar using a Harvi. This video unravelled some of the practical aspects. Still not sure exactly where to place the CT clamps, might be a bit of trial and error.
Love this channel such, great content with humour to boot! ....but I would like to see some actual real life system combinations, like how would this company products work with say the Octopus Powerloop? Perhaps you could ask the question and do another video on these examples!
This "interview" style explanation of what it is and what it does comes across to me as quite a laboured explanation. My take away is that it is basically a smart switch that keeps the power within the house rather that exporting it to the grid OR allows the consumption of the same amount of electricity as being generated and exported out to the grid.
Am I correct to assume that the Zappi can only take priority over charging the house battery if the house battery is AC coupled? I am currently sitting here on a sunny winter's day waiting for my DC coupled LG Chem battery to reach 100% so that I can put a bit my charge into my car.
We have an EDDI and 6.3kW solar panels. Has eliminated use of gas for water and house heating over last 12 months. One small negative- the unit is high on a wall and difficult to read as the screen is small and grey. A larger screen would help
I had an Immersun installed around 5 years ago, and every summer I switch of my boiler and get all of our hot water heated by the surplus electricity from the solar panels. This sounds like a next generation of one of those. It was a great investment.
Me too! And will be fitting their 2 Gen Eddi/Zappi combination in my new place soon.
Yes Ive got an immersun. It's not calibrating right now ..still all seems functional. However with lack of calibration. I may need the Eddi Any ideas of support and fixing this. Can't find prob even changing the CT cables. Let me know thanks
Eddi takes up the solar less than 1.2 kW and Zappi on ECO+ takes the surplus above up to my peak of 3.5 kW. Works perfectly to get self usage up to Max .
Is it working with tap hot water only or can be used for heating radiators too?
Can I use it to solely use it to charge an Anker power station? Thanks
Where I stay grid export is not allowed. I want to use an Eddi to warm my immersion water heater but can not see how the Eddi CT clamp will not interfere with the export limiter CT clamp. I use a Solis Grid tie inverter with CT clamp for zero export thus wasting large amounts of power daily. Is there any inverter with a integrated hot water power diverter? How does the Eddi work on a off grid inverter?
Can I use this to store *all* the energy my pv generates? My idea is to install a small solar panel on the wall - just to provide a modest amount of free hot water during the summer when my gas boiler is off. Or am I being unrealistic ? thanks (single person household).
If you have your central heating circulating pump separate to your boiler would you still be able to use your heating despite the boiler being switched off through the spring to autumn period. Meaning the Eddie would be doing the heating of the water as opposed to the boiler and the central heating pump circulates the hot water via the three port valve through your radiators?
Can we get this stuff in NZ?
I love the concept, although the business case doesn’t appear to stack up. It looks like I get 3x the cost of Gas if I export my excess solar power (15p/kWh). So I’d be better off selling my excess solar as export and then buy gas to heat my water. Or have I got this wrong?
I think this is wrong. When I run the gas it usually is consumed at about 8kWh, so to run an hour is about 8p x8kWh = 64p. If you had 2kWh of excess solar that means you'd get 30p an hour on export. Happy to be corrected. I seem to spend about £1 a day on gas for hot water a day and more in winter.
We've got an i boost solar diverter, same idea but a relatively dumb device. Over the last five years it's averaged about 2.5kWh into the hot water every day. As it only takes about 3 - 4kWh to completely heat the tank most of the year free hot water. IMHO this should be standard on any PV installation.
Is there something similar to this available in North America?
I developed my own unit that does this in 2010, 1 of the problems i have always found it that old houses have immersion heaters, ontop of the tanks, useless as you only get the top half of the tank beeing heated. My current sytem stirs the tank untill the top and botton achieve the same temperature, on an old tank. But yes lovelly sytem which is saving me hndreds of pounds a year.
A Great Grimsby innovating company
This looks very familiar to the ImmerSUN diverter ....Is it the same ?
Brilliant products. I have the Eddi, Harvi and Hub, but I'm holding off on the Zappi until there is a Zappi 3 that does V2H then it will be a real market leader.
Do you drive leaf ?
@@AdrianMcDaid Not yet,. Waiting for V2H.
@@Pablo-tw7tt i just bought batteries. Car not much good if it not at house.
I have one of these and it's off permanently because of current export rates available up to 16p - effectively paying more than double per Kwh to heat water vs gas. Only reason to have one of these is if you want to reduce your carbon footprint, but even then, exporting solar to grid, reduces the grid fossil intensity and your neighbour can use solar power rather than from a gas power station
The Eddie is a wonderful device, problem is most homes I have visited do not have a hot water tank. A large proportion of homes over the past 30 years have been converted to Combi boilers. To change back would be very costly. Having enquired with some plumbers about installing a hot water tank on a Combi system, none were willing to do it, although they said it could be done, all said I would be as well to change back to a normal boiler system. So we will wait to see how our new Solar PV + battery storage system works before dealing with our gas heating. We may be able to change to elect heating with an Eddie and a hot water storage system, at this time it’s a step too far financially.
I'm in a similar boat. I'm looking at getting a hot water tank + an air source heat pump eventually Though consider my own approach.. You don't have to follow it, but this is how I plan on doing that work. My house is also currently very well insulated, but not air tight - I'll get 8 more panels for my flat roof, and batteries. I'll then have a 3.2Kw system on a west facing roof, and another 3.2Kw system on a forcibly south facing roof, because they can angle it - I'll also get batteries, so I've got 15Kw - Currently, the cheapest tariff is 12p/Kwh at night from Octopus. If you're also already on Octopus, the export tariff is around 22p/KwH on the agile tariff (As it's agile, it does change obviously). That gives me some energy security for what I want to do.. Whilst I'm saving up to properly decarbonise the house, it makes more sense from a financial pov to charge up batteries at night and export 100% of my solar panel excess into the grid - Then make my house super air tight - Then install an MVHR, that's properly designed - Then get triple glazing - Then upsize my radiators - Finally, add a heat pump tank + air source heat pump I see it as a long project to get the absolute best possible results. I don't want to just bang in an ASHP and call it a day. They work best if your house is air tight and well insulated anyway, which is exactly why I'd do that after doing everything possible to reduce energy requirements first. I'd also hope that by putting the heat pump stuff in last, it means technology will have moved on a bit more too You may also wonder what my rationale is behind putting an MVHR in before putting triple glazing in for example, and that's largely because I figure if I get the super duper expensive stuff out of the way first, the rest becomes a bit easier Besides, if I've already made my house super air tight, then that means I don't need a big ASHP too
What I would like.... I have been looking at what to do with a 20 year old gas boiler with a radiator system that does not exactly work so well as two extensions, and I am wondering if this type of system could be applied to ceramic radiators, as well as a new tank as I have a combi-boiler, to allow them to take priority especially when negative pricing available. I know most people will say heat pumps! but as I look to start again with the heating, I am looking as broadly as possible at alternatives.
Have you thought about a gas-fired heat pump? Very cheap to run. Ecotricity and Good Energy sell green (non-polluting) gas, and it's much cheaper than electric.
You can get air-to-water heat pumps that make hot water for both domestic and space heating use. Daikin makes such a system and it's likely other manufacturers do as well. Seems like a controller like this could prioritize space heating, if you have thermal storage (water tank). I don't know how useful it would be with electric heating like ceramic radiators, since they're on when you need them and there's no way to move energy from when you have a surplus to when you have a deficit... you need storage that works over some hours (rather than minutes) to do that.
Wish our zappi worked - still not functioning after 6 weeks!
Really great kit. However one annoyance is that if you have an Eddi, Zappi, and a Powerwall you cannot split the priority of the 2 MyEnergi devices. For example, I would like my excess solar generation to go 1st to my EV via the Zappi and then to my Powerwall and finally to my Eddi to heat my Mixergy tank prior to exporting. But I can only have Zappi and Eddi (in either order) before or after the powerwall, not one either side.
Pass the eddi ac supply cable through the CT that the powerwall uses (leaving the grid in too) so the powerwall can't 'see' the eddi consumption (or use another ct wired in parallel)
This does not work with 3 phase AC system ?
Why are they separate units?
Great but it should take into account the price your paying and earning. To decide whats best use for the surplus electric
Absolutely - in the UK the price I can get for a fixed rate export of electricity per kWh is more than I pay for gas so unless you are one of the lucky few who get credited for export even if it does not happen this does not make economic sense. As the greener thing to do it may well make sense as you are of setting certain gas consumption against what on occasions may be oil or coal burning.
Crispy: Thx fo being the only one astute enough to comprehend the conundrum that I posed 2 months ago. (But I guess it helped, that you're actually experiencing it) To correct the imbalance in the system, they just need to offset NG's effects on us at a higher rate, such as by raising taxation on it, due to its negative externalities. (and/or lower (what you call across the pond as) export rates on electricity, but ideally they should be set by supply and demand) Good luck with them getting it right.
There are several similar types of immersion heater diverters around. I have had a solar iBoost for around 5yrs now does the same job. Good to bring this type of thing to peoples attention though.
Are you happy with the iBoost? I think it’s cheaper than the Eddi ??
@@helenalovelock1030 Its more than paid for itself. I have pretty old boiler. I have set the immersion stat temp higher than the boilers water temp. This means it keeps the water over the temp the boiler comes on at so if you are not using a lot of water it just keeps it hot. In summer the boiler is pretty much redundant. I have 3.5kw of solar so more than enough.
Wondering if this is still relevant if you have a mixergy water tank???
Hi, I use iboost ( already in-place before I changed my boiler and cylinder earlier this year) with my Mixergy but thinking of replacing with an Eddie system
I know it’s different technology . I have solar that heats the water directly, is that still not better as it does not have conversion loss. I also don’t have the environmental impact of all the electrical boxes , it’s just a pump and 2 temp sensors. I appreciate it does not charge my car.
Pity it's a resistance heater rather that a heat pump. That said, it may be better environmentally to export the excess power to the grid to offset the use of a fossil fuel power station.
I believe that it can power a heat pump
@@timjefferson1886 it's an even bigger pity that is is promoting resistance heating then.
Add on board has relays which can be used to signal a heat pump that there's enough spare electricity to turn on. We're fitting both in January and disconnecting from gas.
@@petecousins6364 cool. Good luck.
A heat pump would not be so practical and could even be less efficient as: Heat pumps don't work very efficiently being turned on and off too quickly, each time the sun goes in or the kettle is turned on. (Need to get up to temperature by running for extended periods) Plus Heat pumps normally work on a constraint fixed min power, compared to a resistance heater which could work from varying amounts of spare energy and would not care if turned on and off dozens of times a day. So would probably be far more cost-effective to just install an extra solar panel or two to make up the difference.
This would have got us to install solar PV rather than solar thermal if it had been available all those years ago when we had our system installed. Having solar thermal is great, but its nowhere near as flexible as solar PV, and things like this (and similar products as this isn't a new idea) give a brilliant "energy dump" to pop excess generated energy into. Once our solar thermal water tank is at 60ºC that's it - any excess solar energy is "wasted".
Same for me, I am trying to get another electric heating element installed at the bottom of my tank.
You could set the tank temperature a bit higher - 70C is not unreasonable. Also - a solar thermal array using vacuum tubes is around 70% efficient so much better use of roof space to heat water than PV. Agree that once you have a full tank there is little else left to do with it - unless either you had a hot tub you could divert heat .
I have solar PV, and a timer on my immersion heater, this is way cheaper than this kit and I like others do not understand why features require more than one bit each with Quite a cost. If you don't mind the issue of payback this stuff is brilliant.
I was wondering the same. Instead of having 3 different boxes, each controlling one load, why not have one box with 3-5 terminals (for car, heater, battery, ...)?
@@zlmdragon. Apples vs. oranges. Having 1 or 2 additional terminals would make virtually no difference in price, especially when you can get rid of all the circuitry necessary for communication between multiple devices.
@@zlmdragon. ? Maybe I misunderstood, but didn't you present a _counter_ argument to having just one device with more connectors?
Nice
I think that this is a great concept but I'm not sure the pay-back is there if the Eddi fails around 5 years. I know that reducing the power to an immersion heater puts a lot of strain on the components.
Your be lucky to get 5 years out of it, in my experience they only last a little over 2 years. If the company had any confidence in there products they would give at least 10 years.
Alas no one offering anything as advanced here in Norway as far as I know.
Its so painful to watch companies put forward people to explain their products who do not understand their potential customers, luckily some good steering from the host helped out a lot but could have been so much better with a company rep who knows how to explain the benefits to potential customers. Examples such as (meter tails = grid feed in to main meter) & (CT clamp to cable = clip on to cable rather than cut cable) etc.
Gosh, so much energy! So that's the future, is it? Crumbs. How the other half live, eh? Very cosy. I don't have any heating in my home whatsoever. Can't afford it. No hot water, either. Way too expensive. [Two bedroom terraced house, built in 1913, north of England.] Winter and summer, I use an average of 22kWh of electricity per month. That's not a typo. Twenty-two. I aim for an annual consumption of 270kWh. Incidentally, the trick to washing in freezing cold water is to divide your body into sevenths. That way 6/7 of you remains reasonably warm while only one bit shivers. It's basically: right leg, left leg, lower body, upper body, left arm, right arm, head. I'm not a big fan of cold water. I use a microfibre cloth and plenty of soap (or an antibacterial hand gel which is nice and tingly): do one leg and foot, then rub dry vigorously, then the other leg and foot. Lower body (yikes!); upper body (this can take some time when there are 1,200 acres of boob to negotiate); the arms are the easiest bits, and the head and hair is just miserable. I made myself a double-thick woolly hat for winter, though. Whee.
Reminds me of my childhood in the North East. Bathtime in a galvanised tub (basically a big bucket) in front of the coal fire on a Sunday evening. Boy those winters were cold in the 60's
Rasberry pi zero + 2-CH Triac HAT for Raspberry Pi + small micro sd + fan - It works and cost 40 EUR. It can be made even cheper, but I was lazy.
How does this work?
@@CrashUK28 Simple script running on rasberry PI is tracking energy flow (import/export from the grid). If there is export -> increse angle. Import -> decrese angle. Angle (range 0-180) set how long of the half sine wave heater turned on.
Consumers be warned, that if you want smart features, then you also need the Smart Hub - which will set you back approximately another £90-£100...
Boy would I love to get rid of the gas bill but here in USA aka the greatest country in the world, I am pretty sure this new way to heat water is not on offer at the local Home Depot.
Do you think this could be used in the future to control a air source heat pump which is used to heat a hot water cylinder? As my farther in law has PV and air souse heat pump. Would make more sense if it could be told to turn on and use the energy form the PV instead of exporting it to the grid. I think that Air sources heat pump will become much more common all over the country over the next decade.
What you need is a Mixergy smart hot water tank, Robert has one of these. It works with the Eddi, ASHP and conventional heating like gas. Their App enables you to change heat source and how much hot water you want to heat too. Have a look at their website.
How much does it cost please?
More than you will ever save using it!!
@@timpala5841 😂😂😂
others sell the same ImmerSun and others
It looks impressive on your video but why don't you inform the people that this device does NOT work when you are limited to "ZERO export" or have an off-grid inverter.
Resubscribing now that the ridiculous number of ads has gone.
Yes apologies, google added soooo many adds (without our knowledge) but we can override them now. Glad to see you back
@@EverythingElectricShow I stayed a member regardless but I just couldn’t watch the podcasts with that many ads. I’m so glad to hear you’ve been able to make it more reasonable. Thank you. It really is appreciated.
Massive losses I would think: PV => car is two ac dc conversions at 20% loss. The Eddi seems a more logical thing. PV=>inverter=>battery=>car: three conversions. RSVP
If you came looking for an easy-to-understand explainer on the Eddi, this is probably not the best video to watch. There are better, more recent ones out there. Look elsewhere ..
Probably saves about £8 of gas/ month in summer months.
interesting, but it's like watching two straight men together that fear the other is gay, what's with the distance between you two in the vid? so he can't whisper in your ear? :D
One simple diagram would have been good Also an. overvierw to start .I still don't know what the aim is ! Crap presentation. Sorry
Pffff. One of the worst salesman ever. Good product btw but not exceptionaly new.
Don't mislead the public!!!!. For hot water is designed vacuum tubes and flat panels, PV- change batteries and EV.. so,don't talk a bulshit!
