FREE hot water using the Eddi energy diverter from Myenergi
Переглядів 59,956
День томуEddi is an intelligent energy diverter which helps prosumers use self generated energy at home.
Taking solar PV or wind energy, the Eddi measures the amount of energy being generated and diverts this so it's used to heat hot water with an immersion heater.
Eddi measures generated energy using a directly connected current transformer (CT) or a wireless CT with the Myenergi Harvi.
Eddi can also be used to divert energy to other resistive heating loads such as storage heaters, underfloor heating or even an electric Aga.

Just want to mention - Sunsynk Solar systems can easily do this what the EDDI does. You set the menu to export power via the AUX port to drive the immersion heater. Surplus energy from the solar panels are used to charge the batteries while power is sent to the immersion heater. The export kick in percentage can easily be adjusted to send power to the immersion heater.

Would a larger antenna improve the wifi quality for connection?

The Immersion ( Top Cylinder ) Thanks again for an amazing video

I have 3 Immersun devices, eddi is the more modern device. A really good concept👍 But the energy you divert is in real NOT for free! Your PV and the installation has its price! Its a good Idea to use your energy for yourself, here in my country you get only roundabout 6 ct for every kWh. For every kWh from the grid, you must pay 36 ct. 😉

Hi. I have an Eddi energy diverter wirelessly connected to my solar panel setup. It works great, but I am finding that if I use all the hot water and try to heat more through the Boost, it is taking a long time. You mentioned the bypass switch at the bottom for a quick top up. Would using the bypass switch heat the water faster the Boost signal? Does the diverter limit the power getting to the tank compared to direct connection to input?

@johnspittal879 Рік тому
We have an electric central heating system from Thermaflow model TH12 330U Mk2. This is effectively an immersion heater which stores hot water which is heated up in off peak and used later to provide HW and CH. Can you confirm for me that the EDDI unit can be connected to this Thermaflow boiler. We could then use spare energy from solar to heat up this tank.

@anthonydyer3939 3 роки тому
I'll be getting a version of this made by SolarEdge. Same Principle. I've got a 170litre hot water tank. That's about 10.5kwH of hot water storage if you raise the incoming fresh water temperature by 50 degrees (15 degrees --> 65 degrees). So if you use up that entire tanks worth of hot water each day, then this is an excellent option. Be mindful that a 10kwH battery for comparison is between £5-£7k at the moment. So the Eddi is very good value for money.
@ek9772 3 роки тому
Anthony Dyer same principle up to a point. However, functions, options, and performance are not the same. In addition, Eddi will work with a hot water heat pump, and the product from SolarEdge does not. If you, also, have a car charger, they will both work individually and together to increase your production of solar energy. They have numerous other functions not implemented by SolarEdge, and the installation is simpler since no anchoring of a copper rod is needed. No wiring is required to a central inverter or between them. I encourage you to read the manual for both the Eddi and the Zappi.
@MultiOutdoorman Рік тому
I have the IMMERSUN ( proportional load diversional controller ) unit which was the predecessor to the EDDI. Mine has 2 ct coils, grid and pv. It monitors pv production and house consumption and dumps the excess energy into an immersion heater. The 2nd circuit ( when water heater max is reached) supplies an electric towel radiator. There is also a 3rd priority which is a relay function to permit ( for example) a battery charger to operate. The unit looks identical to the Eddi. I wonder if the Harvi or the hub would see it ? My Immersun device has a separate accessory too ... a little bridge/router that links to the antenna and wifi, which allows online monitoring also !

In our case we have the Immersun unit that provides similar function. As we run 2 x 210L tanks on 4kW solar system the Immersun is located near distribution panel and the connected to immersion heaters using existing cabling. Installing this way the unit is near the meter so current transformer installation is trivial. Generally our boiler is OFF from late April to late September and we do not use the boost function.

The aim is to be able to automatically boost the temperature in the cylinder with the boiler, should we need to.

Ach, been involved with renewables and energy saving products for a number of years, mainly back in 2012-2013, these products look fancy and the concept always sounds great, sales pitch, glossy brochures etc - however the savings are negligible compared to what you pay for the device. Forecasted savings and claims of whatever % on your energy bills never tends to be the true figure. ROI is always high. A neat looking little product if you have money to throw away though. Probably similar to immersun, iBoost, etc. It’s like when they introduced domestic voltage optimisation, you’ll never save as much as they claim.

@iggifer 3 роки тому
@@davids5498 I concur to a degree, Immersuns are just made terribly and fail all the time. If you exclusively use electricity to heat your DHW and don't use gas, then it will save you money - assuming the unit doesn't fail before ROI. An Eddi is £400. If you only use electricity to heat your hot water, your'e talking a ROI of around* a year. Assuming 15p per kWH - 45p an hour. £400/0.45p=888.88 /365 = 2.44 hours a day. Unless you live alone, an immersion is gonna be on for longer than that each day. Obviously being in the UK you're not necessarily going to get 365 days with enough light to heat your water tank, but an ROI of 18m-2 years isn't too bad (if it lasts that long!)

In addition, you said, “these products look fancy and the concept always sounds great.” You work in renewable energy with products making fancy claims like solar, wind, and storage batteries, and you are unwilling to inspect a new product?

I'm hoping to install around 8Kw of solar panels and then get a Zappi to run a modest 2nd hand electric car. As the property has an electric shower I would like to send power to a bank of THREE 60 watt, and a 500/1000 watt electrical heaters as I'm disabled and enjoy a warm area in my living room as I prefer to concentrate heat into one room as opposed to using the gas combi boiler to heat the whole place as I live on my own. I also use a 5 litre urn for not drinks so would like to know if using a Harvi and Zappi then I could automatically use available solar power to first charge the car and once that was full automatically get the solar to heat the run and then my bank of small electric heaters? At the moment I only have a small amount of solar and use the ct data on the living room monitor to see if I am generating enough power to manually turn on the heaters which is a bit laborious.

@deang5622 Рік тому
Unlikely. The current is set by the load impedance and the voltage that is applied to it. Usually electrical things just turn the power on and off using a fixed voltage - at mains voltage. For electric heaters, the controller is typically a simple on/off device, and that is cheap and easy to implement It takes more electronics to be able to control the current to it and start using techniques such as pulse width modulation, or an alternative is to directly control the current by continually variable voltage. It's a specialised form of control and it is unlikely a power diverter for renewable energy will incorporate such functionality.

And then use a clamp meter to check the output of the CT before and after the second CT is added to ensured continued accuracy of it when the second CT is introduced. And I would do this for both CTs.

"Free" is a very subjective term. Lets be 100% clear, whilst this is without doubt a clever unit it firstly relies upon you having some form of electrical micro generation installation - Solar PV, Wind Turbine etc. Then the unit itself is also not free - appears to be around £400 supplied + installation cost. The Harvi unit seems to be around another £100 supplied. There are other units available from other manufacturers which seem to range from about £300 plus installation. Whether these are fully feature compatible I don't know. I think it would be reasonable to expect a qualified electrician to charge a couple of hours work to install this. That's making the large assumption they wouldn't require an EICR prior to this also........ Return On Investment (ROI or payback) is probably around minimum 5-7+years depending on your energy consumption or use case and installation costs.

@jameslarwood5276 Рік тому
How do you make any savings with these? 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?

@deang5622 Рік тому
It doesn't really matter how long it takes to heat the water. You're taking energy produced from the sun, using that to heat your water and reducing how much electricity you consume from the national grid, and you save money by doing that. You don't save any more money by heating the water faster. To use figures posted by another user, figures I have confirmed are accurate, if the tank is 170 litres, and you heat the water up by 50 Celcius, it will take approximately 9.8- 10.5 KWh of energy to do it. (The specific heat capacity of water is approximately 4200 joules per kilogramme per degree Celcius), and 170 litres of water weighs 170Kg. So you can do the multiplication and conversion from joules to KWh. Heating the water slowly could result in energy lost to the environment but the tanks are well insulated. The only counter argument to that above is if you have a large PV installation and you have more surplus power being produced than the power rating of the diverter, and then you're not benefiting as much as you could from the solar panels.

If your mathematical ability is not very high, then consider going down the electrician route.

It all looks good on this Video, but what they don't tell you is that this device does not work if you have ZERO EXPORT /not allowed to export or have an Off-grid inverter
@efixx 2 роки тому
Why does it not work for zero export tariffs?

@nic9824 Рік тому
Please inform the viewers that the unit does not work on an Off grid inverter like an Axpert or Goodwe so you are restricted to using export/ grid tie inverters WITHOUT ZERO EXPORT configuration only. This makes it unsuitable for many applications.

Did you pay for the Eddi? Di you pay for the associated PV, etc? So how is it "free"?
@deang5622 Рік тому
It is free in that once all the apparatus costs and installation costs have been paid, there is no charges being incurred for producing and using the electricity generated by the solar panel. That is quite accepted as what is meant by free, compared to your consuming electricity from the national grid which you are charged for per kWh. And obviously, when installing renewable energy generation systems, the total cost of ownership is important and how the pence per kWh compares to using national grid power.
@mosfet500 Рік тому
@@deang5622 Yes, but you spent money on a system and a product that you no longer have and could have paid for hot water with. It's not free until all the initial costs have been absorbed by hot water production which is years. It's called ROI (return on investment). Look, I do it too, put in systems that take years to recover but I do it for autonomy and to hedge inflation costs but it's not free.
@deang5622 Рік тому
@@mosfet500 Only true if the user is not using the system anymore. And total cost of ownership along with a comparison of the pence per kWh for both the photovoltaic system and the national grid consumed power I already covered.
@mosfet500 Рік тому
@@deang5622 No, it's true right up to the point where the ROI is achieved. After that point it is free, before that it's not. If the systems are used to run other appliances, house, whatever then then it is free once that ROI is realized. That's specific to you and relative to everyone else, if someone has their system paid off and has reached the ROI then it free for them specifically. Bottom line, can you but this device and have free hot water? No, the money it cost for the device has to be accounted for.
@deang5622 Рік тому
@@mosfet500 No. You are focussing purely on the ROI, or pay back period. There are other ways to assess the cost of a project.
@wobby1516 2 роки тому
Not really free energy, or at least not until the Eddi is paid for. Don’t get me wrong it’s a great unit, I’ve have one but it does have a cost and that’s quite high.
@stevechambers8869 3 роки тому
Free hot water after you have avoided the £400-£500 of grid electricity or gas units that the Eddi cost.....plus the Harvi too of course.....and the solar PV. I get fed up with return OF investment being ignored when this type of tech is marketed. How many years to break even?
@oliverriall 3 роки тому
Indeed mate. I think it's expensive and I don't need to pay to have it installed.
@efixx 3 роки тому
The aim of this video was to explore the product itself. If you dig around UKposts you’ll see lots of Eddi owner videos talking about the economics etc.
@stevechambers8869 3 роки тому

@markrainford1219 3 роки тому
It probably works out as the most expensive and least convenient way of producing hot water not to mention the least efficient with PV panels being only 20% efficient. The DC then goes through an inverter to convert it to AC to power an immersion heater! Might as well just have one or two PV panels permanently wired to a 500W immersion heater. Or way better still, wet solar collectors.
@davids5498 3 роки тому
Steve Chambers Exactly. This is the point I made on another comment here. ROI, install cost, etc
