Re: SEG and tax implications

Yes, my understanding too. However, for a normal domestic setup it seems unrealistic ( to check ) and bad PR. Even the slightest mention of TAX would be enough to put a lot of people off getting Solar PV. Something like : ( PV Total + Import ) MINUS Export = Actual Usage If ( Export / Actual Usage >...

Re: Building an EV more efficient than walking

It's also worth noting that electric bikes are more CO2 efficient than people-powered bikes. This is because the CO2 footprint of food is rather higher than electricity, even if it is relatively dirty electricity. I'd be interested to see if anyone has done rigorous and peer-reviewed energy analysi...

Re: Outgoing Octopus

I'm hearing that folk renewing on the Outgoing Octopus export fixed tariff are now being renewed onto a variable export tariff, currently still fixed at 15p / kWh but for how much longer ? :? I have just shifted over from FLUX to COSY, in anticipation that running two small A2A Heatpumps during col...

Re: The Boy That Cried PV Extension

Small update on plans here, I was chatting on a thread, . . . . <snip> Having just read the above. I wondered if you had considered a DHW-only heatpump to complement your A2A units. It's not something I'm considering as I use minute amounts of hot water ( and don't want a tankful sitting around her...

Re: BBC Sounds -

I'd recommend this interesting YouTube presentation from Peter Carter. This is the information that nearly everyone around me does not want to think about or ever discuss . . . . . I suspect that (unsustainable) super-humanity is now so deeply entrenched in our expectations that life may become diff...

Re: Internet radio

Here is my DIY Internet Radio + digital media player :- It's a Raspberry Pi Zero 2W, running PiCorePlayer. The Zero board (behind) is connected to a HiFiBerry AMP 2 ( digital-to-analogue converter + amplifier ). It's not really very high fidelity, but good enough for me . . . bearing in mind that th...

Re: Heating Mat for battery warming - thoughts / recommendations ?

Unfortunately, I don't know the risk of a Pylontech Battery fire. ( The installer chose the location and did not discuss any pros&cons . . . . 8 months prior to the change in battery location guidance. ) I can see that it would be difficult for the Fire Service to fight a battery fire through a ...

Re: Heating Mat for battery warming - thoughts / recommendations ?

I have upgraded from manual monitoring : - PREVIOUSLY : I (remotely) read a temperature Sensor near the Batteries (attic) and I switch the WiFi socket ( with connected heating elements ), On/Off Now :- Raspberry Pi Zero 2W - runs a Python program to switch ON the heating elements if coldest cell tem...

Yep, that was a good listen. I actually stopped - doing other tasks, around the house - to listen to the radio.

Re: Ripple CFD vote.....

Thanks to Nowty for the additional information & insight. Finally, I will vote for a CFD @ Kirk Hill. KH represents one-third of my ( meagre ) Ripple capacity. This will balance the risk/reward considerations - as Graig Fatha ( forever non-CFD ) is the other two-thirds. Roll-up, roll-up : place ...
