Octopus Cosy 6 launched

ChickenBig · 2023-09-14T15:17:30Z

Octopus Energy unveils new smart heat system ‘Cosy Octopus’ at Energy Tech Summit Sounds interesting, even if specs are TBD. “The combination of a high-temperature heat pump (as hot as a gas boiler), Octopus smart tariffs and room sensors across your home doesn’t just open up cheaper clean heating - but more comfort too.” Interesting to see this going against the slow-and-steady running philosophy.

However I do agree that, by the time you take into account drains, airbricks and other openings, they can be quite restrictive, particularly since we currently pipe into our houses an unlimited supply of methane.

Do bear in mind, though, that methane is lighter than air and so dissipates easily and won’t naturally pool in drains and underground voids.

That’s not to say regulations are or are not overly restrictive; just that there’s not a lot to be gained by comparing R290 with mains gas in terms of safety procedures.

Fair enough, but gas explosions are not unknown and the quantity is not limited.

You can also have a 13kg propane cannister in a boat or caravan. The location where its stored has to be ventilated (in a boat, not sure about a caravan), but its piped into the interior where it could pool, eg in the bilges.

4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.

Agreed, @jamespa, and I remember seeing a video whereby the RNLI teamed up with some Royal Navy ordnance experts to demonstrate the effect of (and likelihood of) pooled bottled gas igniting in a boat. The results were certainly dramatic.

Absolutely. An explosion requires a very specific set of conditions and they took three or four attempts to understand those conditions in detail. Once they found them, of course, the boat was utterly obliterated, and we all hace a better understanding of what not to do.

Oh dear, someone majorly goofed at Octopus. They've credited me back about a year's worth of bills today. Bumping my account credit from £375 to £1568. Maybe it was someone's last day today and they 'wanted to do a Robin Hood'. Anyone else had an unexpected Octopus windfall today? If it was an Octopus IT fekk-up, then it will be someone's last day next Friday...
