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:/...

Re: SEG and tax implications

I guess that is where the maximum 120% of consumption value used by Ripple comes from. What is then unclear is what is the tax situation when a homeowner has rooftop solar PV and a Ripple investment? But as previously mentioned, how is the solar PV generation value collected? It was under FIT, but n...

Re: Part ownership of a Ripple Wind Turbine, fancy it?

So the first batch of the DW solar panels are now mounted on their frames, with a gold standard array checked and available for comparison when completing the rest. https://i.postimg.cc/67MhNw0S/DW-1st-array-Screenshot-2024-11-15-144005.jpg The sequence of works as described by Ripple is to complete...

Re: Storage Heaters, Tariffs & Control

I am with Octopus on an E7 tariff, with a SMET2 meter that uses 2 consumption registers and stores the tariff rates for reporting on the IHDisplay. It is not quite as cheap as the EV specific tariffs but I find it reliable to be able to align my device timers with the 7 hour cheap rate period and ca...
