@adam-c Bobby was a charming chap. Nice chat and even laughed at a few of my jokes. 
I think I’m creating a proxy SCOP. Here’s how. 
I have an electric meter that measures the amount of electric used by the Daikin. This is accurate. 
Press left hand scroll wheel and turn until you reach information. Rotate to Energy data and click again. Select Produced heat by clicking and then keep rotating the wheel until you hit a number. This I believe is the energy produced since installation.

Divide produced number by used number to get SCOP. 

And in creating this explanation I’ve realised I’ve under reported my SCOP. If you rotate the right wheel, whilst on produced since installation, reading, it goes thru three readings: sun, shower and summed. I think this is heating, hot water and total. And I’ve been basing my readings on the heating. But my electric energy in is total. 

So my real SCOP is 15935/4124 = 3.78

I hope this helps and thanks for getting me to check my logic. 

PS. I will be at FCL on Friday 29th again this year. I hope to meet RHH.co.uk’ers there 

First annual service of the Daikin booked for 5th May. As part of my fixed price 10 warranty and service package. 
It is Daikin Bristol who will be doing the work 
Will report what they do. 

The annualised scores are in. Pretty similar to last months, but I’m pleased. 
Consumed 4239kWh for heating and hot water against an MCS predicted 7283kWh. Or we consumed 58.2% of predicted (is the prediction poor or the system more efficient?  Difficult to tell)

The Daikin says it produced 16044kWh of heat giving a SCOP of 3.78. Or 378% efficient!  Which seems good. 

At my current maximum Octopus Go rate of 30.78p/kWh this = £1305.  I say maximum as my hot water is heated at night at 7.5p/kWh

This compares to 1500L of oil at 91p/L current price = £1365

So overall a good annual result. I have switched over to weather compensation curve now. I think. I will get the Daikin service engineer to confirm at the service. 

The aim this year will be to run the ASHP longer, but at a lower temperature. To compare SCOPs between the two control systems. 

@julianc, very impressive numbers and your system is running very well. You must be pleased with that. It'll be interesting to see how it compares next winter versus weather compensation enabled. 

@editor yes very pleased Mars. 
I wonder if we can get above SCOP of 4?  Maybe 4.5

We will see

Hi Julian, 

I also installed a remote power meter so that's a great way to calculate SCOP, will reset mine at some point and then see what I get. But not being able to differentiate between the heating and the hot water is a real limitation. 

Be interested in what they do in the service. I read through the manual and on servicing it says very little but did what it says myself. Other than checking outdoor unit is clean and checking the filter on the indoor unit not much to do. Only maybe software update which I don't think I can do. 

Sadly can't make FCL this year but maybe you can do me and hopefully all Daikin users a favour!

Last time there was a Daikin stand with a gentleman who worked at Daikin UK, not just a installer. 

As a owner/user I am very disappointed at the limited information on performance that Daikin allow. All you get is the data on the small screen which does not even calculate COP for you! I bought and installed the WiFi unit so I can control it over WiFi and hoped for more in the App but no...

I personally would now not actually recommend Daikin as I think this is such a limitation. Mitsubishi give so much more with MELCloud I believe. 

If you could maybe pass this on and if possible can you get a email address for someone senior at Daikin and we could all email to complain? All the equipment is there for monitoring, all they need is a way to sensibly access it!

 Thanks.

Adam

@adam-c despite working in IT services, I think I get enough information from my Daikin. When purchasing, I decided not to add the Wi-Fi module (£150 option?). It’s a bit like my 10 year old solar PV system - used to Bluetooth laptop to the SMA inverter weekly to download and analyse performance. Got bored. 
So each to their own Alex, but it’s not a complaint I have with Daikin. I can see the use if remote problem diagnostics and fix were included - I will raise this. But for me ASHP reliability is more critical and responsive support from Daikin, should their be a problem. The 10 year warranty & fixed price was one of the reasons I picked Daikin over Mitsubishi Ecodan. 
Within the small screen on the Daikin and the energy consumption/produced information screen, it does split total from heating and hot water. So you could note down periodically.  You might also be able to build a logic app in IFTTT, with the right monitoring clamps, but for me it’s ok at the gross costs and SCOP levels. 
I do hope the Daikin engineer will assess the installation and make recommendations for any improvements in performance (other than wear an extra jumper).

The services are very unexciting. You can do almost all of it yourself and the only real value we saw was that they cleaned out the heat exchanger inside the ASHP unit, which in our case had accumulated some corrosive bits from our rads, which can lead to a loss in efficiency. Apart from that, we're obliged to pay for the services because failure to do so after three years (that's with our manufacture) it may void your warranty if anything goes wrong with the heat pump, so probably worth the expense given how expensive the units are. 

I struggle not to think of the servicing rituals as nothing more than money for old rope, a nice cash machine for installers. Making warranties conditional on regular servicing tie's our hands greatly: if we want a warranty, we have to go along with the ritual, whether it is justified or not. ASHPs are not like cars, which are designed to be regularly serviced (brake pads wear as part of their function, engine oil gets dirty and corrosive when it does its job etc). I would happily pay for servicing that did something I couldn't do (without getting some expensive kit) but to pay service hourly rates to clean away some leaves...  

@cathoderay I hope the do a check on the installation. Check compressor pressure, R32 levels, running performance. I hope there is an extensive check list and it’s not just clearing out leaf waste. I will get the details on 5th May

@julianc - it will be interesting to hear what they actually do. I think the only specialist thing done during routine Midea servicing is checking the pressure in the primary heat pump to house (in my case to the plate heat exchanger) circuit and re-pressurising if needed which needs special kit (and glycol/antifreeze). They also check various parameters, but these are not complicated to access, and any DIY competent home owner could do and interpret them.

Ah, the old servicing to maintain warranty scam….

yeah, I wouldn’t bother. It’s not like a combustion appliance that might gas you to death. It’s a fridge, in your garden.
