Optimising LG Therma V R32 using AI - Air Source Heat Pumps (ASHPs)

@bontwoody oh dear! ... but as you say..

I suppose the only other suggestions i have

1. Might they watch YouTube videos or read forums? I think 100% of people that have looked at Fixed Flow vs Weather Compensation will agree WC will always save money. Even if quantum varies. I would suggest average savings 20% plus?

2. The real killer point is that everything is reversible!

But thanks for the update anyway!

@tim441 Just an update Tim, I cant convince them to let me do the changes, so Ive offered to give them an hours tutorial in heat pumps if they want it. Frustrating really but its their money. Thanks for your help.

@bontwoody

Yes, remove schedules for now anyway.

Hopefully you can look at tariffs too. You may be able to get a decent setup using Octopus Cosy or Intelligent ... and tweak schedules to maximise benefit.

But personally I'd focus first on 24x7 AI... then tariff... then further tweaks

@tim441 I think they have schedules set up as they said it was too expensive to run 24/7, but that was off course at 54C :-) Ill set up a WC curve for them at a sensible slab temperature. Thanks Tim

@bontwoody yes.

Are they using external programmers and/or thermostats? Was it a retrofit for previous gas or oil central heating system?

Or have they set schedules in the LG system?

With AI you should run 24x7... and thermostats higher than requirement- especially during setup. Preferably long term too

@tim441 So I havent been over yet, but apparently its not showing that screen now. Its showing this. Does this mean the heating is off? Thanks

@bontwoody yes, but also be easily reversed!

I think i can honestly say its 100% certain they will save money... and still be warm

@tim441 Yes an EV and battery makes a huge difference 😁

Im just waiting for them to give me the go ahead and change things. I guess its a leap of faith for them 😆

@bontwoody yes, that is shocking!!

Depending where you are hopefully it will run at under 40deg much of the time. Right now its 8deg outside here... LWT is at 38deg.... and house a comfortable 21deg.

Saving elec as well as better efficiency. I would not be surprised if savings 25 to 30%

Fyi I'm now on Octopus Intelligent Go tariff as I also have batteries and EV. import price for 2025 averaged under 10p kWh

I guess they can currently feel the heat in the floor. With AI and lower temps the floor may hardly feel warm! But should keep a very comfortable room temp all the same.

Let us know how it goes!

On the main controller you can easily press

+ or - up to 5 deg

This allows temporary changes to test for a few days

- or if weather colder/hotter than normal

- temp tweak if solar gain or holidays

Etc

- without changing the main settings
