How to getthe best out of Octopus Flux

@madtoady You sure about those figures? 1.8kW for a pump makes it a pretty powerful pump, and not sure where the 5.9kW for the ASHP comes from. The rating on an ASHP is it output power, actual electrical power draw will be a lot lower depending on the COP.

PS. I'm also in Kent.

Unfortunately the figures are correct, the power output from the unit is 29.2kW at max power! https://www.thatpondguy.co.uk/product/jetline-premium-210-wifi-model/ that's the reason I hope to run it when the sun is out :)
 
You'll need a solar canopy over that pool to power that lot and the house, must be some pond/pool. ASHP shouldn't run at maximum all the time though, hopefully.

There will be a special UV and heat trapping cover on the pool for sure. I have also purposely overspecced the heater so that when it is running, it won't be running for long.
 
Not sure if this has come up on another post with it being 45 pages, but I came off flux for the winter, with the intent to go back in Spring, however I given it seems to have been nerfed that I will be in no hurry to go back to it.

Instead, I moved to Tomato energy for import (which is 5p off peak at night when I fill my batteries and thermal battery, top up again at 09:30 - 11:30 at 13.37p) and export to Scottish Power for flat 12p at all times.

I am thinking of leaving it for spring / summer and just turning off the top-up charge, so will continue to import at 5p - My batteries plus any daytime generation will likely cover all of my use and then just flat export at the 12p.


That is of course until they nerf the 12p export....

Seems like such an easier option than messing around with Flux - Also less cycling of the batteries with all the forced discharge to get the peak export rates for an extra 50p a day or whatever (and the TE standing charge is like 30p a day less than Flux anyway).
I too moved to TE and also enjoy 5p/kWh for 6hrs a night which fills my 20kW of batteries ready for the day. I only have a small amount of panels so for now they are on SEG, I still get FIT so not too worried about winter gains from solar.
I was intending moving back to Flux in spring, but its so much easier to just overnight charge and top up with with solar that I may stay here for spring at least and play it by ear. My bills so far have been really low :)

I have reduced November from £183 ish last year with e.on to £93 this year with TE and that was with negligible solar generation. My previous Jan / Feb bills were topping £325 so interested to see what I get that down to for 2025.
 
Looks like my export will be less than 1.3 kWh today, the battery is currently down to 25%. Pretty pleased considering we used close to 26 kWh today, and apart from 2.48 kWh of solar that was all cheap rate Go.

My new export algorithm appears to be working perfectly, the last 4 nights we finished at 15% SOC at midnight, charging starts at 00:30.
 
Just got updated prices for Flux from the 1st of April, was looking forward to energy prices going up as thought that would be quite nice for Flux over the summer but seems like although the import prices have gone up, the standard export price has dropped almost 25%! 12.827p down to 9.79p, slight increase in peak export from 25.422p to 27.811p and a decent drop in the standing charge of almost 10p which is nice, but overall Flux seems to be gradually getting worse every time they update the price.

As the overnight import rate has gone up to 15.877p it doesn't even have the advantage of being simple to run as can't just set it to fully charge overnight and still know it will work out OK regardless of the weather, haven't checked the Intelligent Flux prices to see if they're any better, but I am wondering if they're trying to force people that way to give them a reliable source of extra power during the peak hours.

What are peoples thoughts? I did try Agile Import with fixed export for a while, but as prices started going up that became a fairly bad option as there were some very expensive Agile prices at times, and even the overnight rate could be pretty high, plus even more management. Are there better deals worth looking at? Only plus side with Flux for me is that a few nights a week I am away, so can export a reasonable amount without having to draw from the grid till the cheap rate kicks in.

Flux is a terrible tariff now. Either you can get onto intelligent flux which is still very good or go to an EV tariff with cheap overnight rates.

I dont really understand why Octopus are so intent on giving battery users such awful options most of the time. Many are switching to Eon.
 
Any recommendations on the Eon tariff to look at? Not finding any Solar\Battery tariffs on their website.

The Intelligent Flux Tariff looks like it could be pretty good over the summer, but very poor over the winter when you wont be exporting much and paying full price even overnight, really still not keen on the idea of them controlling the battery either.

Next drive v6. Its an EV tariff but they allow solar/battery users as well unlike Octopus who dont(officially!).

Yeah its a summer tariff, works very well south west facing panels as well because they are generating a lot in the peak window. I used it last year over summer and it was much more profitable than anything else. The control aspect is easy to get over, the grid becomes your battery.

import prices have gone up, the standard export price has dropped
I was on Flux from April 2023 until last December when I moved to Go. Flux was really good to start with, but every time the prices went down the export rate decreased more, if the prices went up, then the export rate went up by a smaller percentage, they've basically been erroding the export rate.
What are peoples thoughts
As above I moved to Go in December, IIRC I'd be better off by about £600 a year on Go, and with my system I really milked flux, but it was much more expensive in the winter. I didn't have an EV at the time, and no intention of getting one, although I have now, so saving a further £200 by being on IOG not to mention the huge savings on fuel costs for the car.

That Eon tariff combo looks very good, 7 hours of 6.5p overnight and export at 16.5p, no messing about and should work over winter and summer, very tempted to change, although the website certainly suggests you need an EV to be eligible, I assume you just basically lie about that? Does anyone know why they insist on you having an EV for these tariffs? Seems like it shouldn't matter to them (unless it's just because the expect EV drivers to be more profitable overall due to higher usage, so are trying to attract them).

May just wait till this months DD goes into Octopus, along with my last saving session payout, then get my credit refunded and try to switch.

When you go through to the quote page.

To be eligible you must own or lease an electric vehicle or have a solar storage system and must pay by Direct Debit.
 
Hmm, yes, on the first page it says "you must have an EV or a storage system" on a later page it says "you must have an EV" with no mention of a storage system, I think I will choose to believe the first page!
 
Don’t worry about it, they are not asking for verifiable proof from the millions of people on these tariffs now. Those numbers are only doing one thing, growing.
 
Yep, gone ahead and applied to Eon, so will see what happens. Certainly didn't ask for any proof of EV ownership, so fingers crossed all will go smoothly. I will miss Octopus in some ways as always found them really good in many ways, but the tariff was really starting to take the mick. Also, will hopefully get £34 cashback for switching!

Is flux still crap if you force export during peak?

I guess intelligent flux is worth moving over to and then switch back to another after summer.
 
Flux is as good as dead now with these rates. Just looking back to last summer, the 0200-0500 import rate here was 12.7p and the day export rate 14.3p. Now they are 15.7p and 9.7p respectively.

The cheap time is too short and too expensive. The export rate in the day is feeble and even at peak during 1600-1900 isn't better than the day rate import.

I suspect we'll be seeing more of this on various tariffs and export rates in the future.
 
One question about Eon, setting up the export and they mention a lot that they pay that by cheque, is that actually correct? Or is that for people who aren't Eon import customers, and if I've got an import tariff as well then they'll just credit my account? Seems a bit backwards if it is a cheque these day, and I thought most companies were trying to get away from them.
