Is there an app that lets you change the heating periods?

I believe there's an App. But I don't know what the interface looks like of the options.

It's a pretty underwhelming app. I can do some schedules, and change modes. But that's about it.

Even if it doesn't heat at night, or I switch it to element (defeating heat pump power savings), it doesn't solve the day noise (my office is right next to the pump). I suspect moving it from hard up against the wall would lessen thr vibration noise)

What I noticed is the other air vent is facing the wall. Should it be all sideways so it will have decent airflow. Feels like the heatpump is working really hard due to lack of airflow.

My HWHP turns on when the bottom tank sensor gets to 37 degrees and off when it gets to 59 degrees. This cycle usually takes a couple of hours. 

I'd recommend checking your shower flow rate as you can get a good shower at around 8 l/min with the right shower head. The less hot water you use the more you save. 
I have fitted a low flow shower head - Methven Kiri Satinjet MkII low flow which runs at about 7 l/min. There were a few complaints from the family initially but in a week or so they got use to it.

Yeah you could be bang on the money.

Electrical firm have said plumber needs to look at it, and asked them to make contact.  I suspect  it's not high on their to do. Ill give them a couple of hours then start making firm phone calls.

On my to.do. however we generally don't run shower full pressure, as old tank was small and run out haha.  

Granted, last night I did on purpose, as all the hot water is now 'milky' colour and I was trying to flush it.  Still milky today :(

I got that milky colour from hot water coming out of my rinnai infinity. It will subside though. Could be chlorine and flouride.

Most all in one HWHP have the airflow going sideways or parallel to the wall.

Airflow is very important, you need as much ambient air passing through the coil as possible as you want the warmest air being drawn thorough the coil. The fan is blowing the cold air (as the heat is removed) away from the unit to mix into the general surrounding (ambient) air. This is much more importation the colder it is outside as less heat available in the ambient air. 

Below is an example of clearances from a Gree WHIO installation manual. The Carrier will be similar but I can't find that online yet. 

This is the manual for the Carrier Blue Hot water Heat Pump:

The manual is slightly outdated as it does not mention the electric magnesium anode.

They installed 90 deg, so clearance needs to be more.

looking at the photo, that's not 600mm.

If they rotated it clockwise 90 degrees they also wouldn't need all that crazy pipe work.

Not even 150mm

Exactly my thoughts when I saw it. Reminds me of the stage in Super Mario.
