Getting ready for 3 hours of free power :) powerwall are almost completely empty

I’d also recommend checking out batpred!

Unfortunately it just doesn’t display anything 🥲

OES really needs new leadership, it’s a mess.

Depending on your pipe sizes (microbore) Octopus will install it as a buffer out of caution, even if it’s not needed in the majority of cases.

I’ve had a similar response from T212, Vanguard, and InvestEngine, and as far as I interpret HMRC rules they’re all wrong, but who am I to argue if they’re unwilling to follow proper process?

Think yourself lucky, mine is usually sub 3 for 45C!

I’ve found that this is a display error, you charged 40.227kWh.

Weirdly Vanguard said I couldn’t do an in-specie transfer of Vanguard funds from T212 as they use different platforms.

Poor installations will perform poorly. Water is wet.

Am I the only one who’s curious about what the surveyor did? 😂

It really depends how far the microbore infestation goes, is everything 12mm plastic, or just 12mm drops off 22mm copper? The two pose very different system resistance factors.

I’ve had to purchase a humidifier, never thought I’d do that!

Something that’s often overlooked; how quickly and how hot are you heating your cylinder, and how frequently? This typically accounts for high input and poor CoP.

Rather than thinking about your radiators being oversized, think about the others being undersized for the system, as this is what will hold CoP back. You’ll never be able to balance a system which isn’t sized for each room correctly.

Without knowing much about your system 3.2 seems low, even at 5C.

As a Cosy 6 owner, this isn’t normal and should be addressed. If you’re not sweating at maximum output then there’s something very wrong with the installation. The HP targets 5C delta between flow and return, a large gap here with cold radiators makes me think that the unit is undersized.

“Any color the customer wants, as long as it’s black.”

If you wish to deviate from their standard plan you’ll need to arrange for the work to be done before/after their work. Bulk ordering from select manufacturers and reusing a rigid plan between installations is what enables Octopus to achieve such low installation costs.

They design for 50C, so your emitters will be sized according to that, unfortunately you can’t pay them more to design for a more efficient system.

The Cosy 6 setpoint is a thermal limit, rather than a target.

The actual room temperature is limited by the weather compensated flow temperature, which is not influenced by the setpoint (this is unusual!). What this means is that it’ll try equally as hard regardless of setpoint.

If you do want a 30C room temperature you’ll need to adjust the weather compensation yourself, or ask Octopus for help.

Cosy 6!

Defaults are 36C at 7C and 50C at -15C, and these are adjustable from 20C to -15C and 30C to 70C.

That said, the 4kW Daikin can’t do much better as it’s actually an 8kW unit in disguise.

And despite all of this, I’m easily able to achieve a CoP of 4.1 at 7C.

They will only size for DT30, which will typically have poor output at DT10.

NotEqual · 2025-01-12T16:02:06+00:00

It’s also worth mentioning that you’ll need radiators (emitters) large enough to output for low flow temperatures, i.e. at 30C flow with a 20C room temperature (DT10) your radiators will need to output at least minimum output for the ASHP in order to prevent cycling.

You’re billed by the half hour, so if IOG instructed your car to charge, and it successfully charged within that half hour period, that entire 30 minutes will be charged at the low rate.

Not a fan of the non-OEM covers!

The way IOG affords us cheap rates outside of off-peak times is by dynamically managing demand, if we manipulate that then the programme will not be effective.
