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.
