I do exactly the same. Having worked in industry it’s covered everywhere. I did ACOP L8 a couple of years ago but quite generic and focused on the typical open water tanks sat stagnant for ever and dead legs. Did talk temperature but was geared to a factory rather than a domestic heating system...
No sarcasm intended. Genuinely loving the escalation. I’d have thought it was clear with my post that efficiencies were a focus given I’ve spent nearly a year logging it, but if not, then apologies if I’ve offended you, but if you do have an issue still or in future, just PM me :)
Makes sense...
Hi all
I've had an ASHP for 10 months now, and thought I would share some data. Hopefully its interesting for anybody considering it, and also anybody else who may be getting better or worse and keen to share any settings to improve the efficiency.
I live in a 4 bedroom, detached house, north...
I agree completely. I asked the installer and they just said Google it. Thankfully I found this and got a lot of help and a bit of playing about myself to see what happened
If it’s set to load first for all times other than when you’re doing battery first then it should auto drain from battery before the grid. That’s what mine is doing now on that basis.
Just be aware the battery only charges and discharges at 3kwh so if you whack the oven, kettle and iron on at...
completely misread the original message.
What John said but if you do want the grid to charge the battery, just change the time to when it’s cheaper and it’ll default to load first when its peak and drain battery instead of grid. Or if sun is out, may even charge battery and run the load off...
Ouch!
No expert by any means. Just inquisitive hah
Go into the settings for your inverter on the desktop (scroll down, looks like 3 slide bars in a big round button on the right hand side) and in the settings go to where it says ‘battery first’ if you don’t want any battery charge from grid...
It also depends on the motivation for doing it. Good of the planet, save money etc there’s a point too much battery isn’t as efficient as just buying from the grid if you can get a flex tariff. And if less batteries and still works for the house then less precious metals for the battery etc
You...
I’d also think about the winter and when the sun is minimal. Will you end up with batteries that are empty and no way of filling them?
The tariff I’m on there’s no tie in for it. Can leave or change tariff within octopus easy enough. Other providers and other similar tariffs as well
A better...
I’d be looking at what tariff you’re in. Sounds like 34p kWh during the night. Plenty out there for cheap night time power.
I’m on octopus cosy and it’s 19p kWh during 4-7am and 1-4pm, 34p the others except 4-7pm when it’s 55p ish. I partial charge the battery before 7am to hedge against good...
I set the window for the back end of the cheap period so it starts using battery as soon as the price goes up. Ie I charge 2-4pm as I’m keen to have 100% and if sun hasn’t already filled it, cheap grid power will. Then runs off battery when it rockets between 4-7pm. And just avoid having...
Apologies. I’ve been away. The subsequent messages may have superseded this.
But on basis it charges at max 3kwh a 2 hour time slot will see it full. So I just throttle by having say a 1hr20min time a lot to get it upto about 70% as it doesn’t go lower than 9/10% on discharge. Then it allows me...
