Octopus Agile

wrf12345

"That would be quite something - if all the providers created a version of Agile and made it standing charge free 😅
Everyone complaining will be happy, right?"

It does have logic as it would only work with smart meters, which the govn wants, and the peak rates would have to be even higher and perhaps wider - to a point where it would only work in most cases with solar/batteries, again making the govn happy - meaning less backup power in the grid would be needed for when solar/wind is not available. As a very low user myself I would go for a small battery/inverter and separate AC circuit with the money saved on not paying the s/c... and would be happy!

Just got my Agile renewal. The SC is the same as for the SVT, so about 10p more than now. Hoping for lots of wind and sun in the coming year.

Likewise, I guess we were spoilt with the standing charge.

I have a Meaco "Low Energy" dehumidifier. I confess I haven't bothered to work out what the cost per hour (when used for clothes drying) comes to. Ditto when I leave the computers on sleep and hibernation respectively when not in use. If it's pennies then I'll donate them to the Octopus good causes box.

A bit random, but I've recently found out that dehumidifiers create more heat that any other electric heating devices (ignoring heat pumps).
So for example if you run 200W dehumidifer for 6h and it extracts 2l of water - your house gains 6*200W = 1.2kW of "warmth" + about 0.5kW / litre of latent heat from turning humid air to water so, in this example you get nearly 200% efficiency :-)

So in winter it makes sense to run it during the day (if you don't have gas heating).

It's not quite as good as it seems though, because moisture will evaporate to replace that removed from the air (which doesn't happen at equilibrium) and that will cool the sources of the moisture. But still, it makes a difference, and to the extent that you are preventing humidity creeeping up due to your own breathing and perspiration, cooking, etc, it is killing two birds with one stone. For other uses, like drying laundry, there is no net benfit, as the net effect is just to move liquid water from the clothes to the dehumidifier waste water container.

Yeah, not an easy one, even with the laundry. The wet clothes take the heat out of the air - and then we recycle it, rather than just open the window and let it go.. 

This was more just an idea, that dehumidifer could have 100%+ efficiency

In practice the OP in that thread got a disappointing result, which I suspect came from trusting the nominal rate of extraction which is commonly specified at 30C.

Another problem is that they are often sited in rooms where the heat isn't all that useful. And you don't save any money unless it's in a room where the temperature is actively regulated.  It's a nice idea though.

prices out for tomorrow not good

my dec statements has arrived 16.9p kwh for the north east which is a high priced area
this is on par if not cheaper with original tracker i was on

Oddly enough, I posted something similar a month earlier:

Although I think the chances of reaching a COP of 2 are pretty low!

Probably only applies to refrigerant type dehumidifiers. I'm so sad I once spent time monitoring the input and output air temperature of my dehumidifier and then calculated the energy gain over the amount of leccy consumed. IIRC the gain wasn't much above the margin of error.
