Re: Octopus saving sessions coming 1st Nov

I am also located in the East Midlands, and the Octopus SS is stated as 6pm -7pm as well.

Could there be different timings for each region of the country?

Re: Zonal pricing & curtailment article

So many of these articles only highlight payments made for curtailment (switching off) of wind turbines, but there is never any mention of quantified payback amounts under the contracts for difference system of cap and floor pricing for excess prices paid when the gas generation prices are high. I d...

Re: Type 2 to Commando

In EVSE devices such as the MyEnergi Zappi that can track solar generation when charging an EV at a variable rate, the square wave comms is generated by the Zappi and acted upon by the EV. It is a variable mark-space signal to indicate the maximum current the EV is allowed to take at that instance i...

Re: RTS switch off

With my solar and battery storage system I only have around 1 kWh/month on the peak rate register other than when there are Octopus free sessions during the day, and all the remainder at off-peak prices (currently 12.5p on a 1 year fixed from Oct 2024). My experience with Octopus and missing 30 min...

Re: RTS switch off

I am on Octopus E7 tariff with SMETS2 electric and gas meters to allow automatic readings. The SMETS2 electric meter is configured with 3 registers for peak, off-peak and export which are automatically read over the DCC network once a month for billing purposes. I can also physically read the values...

Re: MVHR vent locations. Opinions...

Surely if it was 100% efficient with an inside temp of 20℃ and outside temp of 0℃ then the air from the inlet would be 10℃? I agree, assuming the supply volume flow rate is the same as the extract. It depends on the heat exchanger... https://en.wikipedia.org/wiki/Countercurrent_exchange is how thin...

Re: Tesla launches the V4 power cabinet...

My main point is that WE DO NOT NEED FASTER CHARGING! We need more 50kW chargers. Agreed, as long as the 50 kW chargers actually achieve that rate and do not drop to 25 kW because 2 chargers are sharing a restricted feed. More 50 kW chargers means less waiting time compared with now when they are c...

Re: ASHP & triple glazing

There was a recent blog describing the Vaillant SensoComfort operating modes (inactive/active/expanded). In Active mode the author found the room influence was not aggressive enough, but that will be affected by the location of the SensoComfort and any external influences such as solar gain. https:/...
