My mum in law had a heat pump installed recently.

Is this a rubbish install?

My first thought was 'Yes'.

They haven't centred the heat pump between the windows. Is there a reason why they haven't done this (any limitations) or is it just a rubbish installation?

Is it normal for it to leak water?

I've attached a few photos (yes, there's a few, but thought it would be better to include as many photos as possible).

Also, please ignore the holes/marks in the wall beneath the heat pump. That wasn't done by the installer.

Looks to me like the indoor unit could be centered on a stud that has 600 mm spacing between the two windows.

Yes, both the indoor and outdoor units produce moisture. It's not usual for a domestic installation to include extra piping to take the water away.

It's got to be mounted on something,
there may have not been a horizontal dwang at the right height , so it had to be mounted on the vertical studs, which could give rise to it not being centred...

As for dripping, yip they do that, although most will usually have some way to allow it to be plumbed it away into a nearby drain etc

i think the lack of centering is exagerated by the lack of curtain rail on the left side. Y.ou'll get used to it

the water will be coming from that pipe that you can see coming out of the ducting outside...its the condensate drain from the internal unit...perfectly normal.

the install looks ok to me considering the uneven cladding. the silicon could have been neater, but ive seen much worse.

From the looks of photo, it is almost central, with the actual windows. The problem is that you have a curtain rail on one window that looks to extend well past the window reveal, which makes it appear like it isn't as central as it is. So if that blind rail was removed, it looks like it would appear more central.

Outside unit will get condensation when on heating, they do not usually have provision for draining them.

Inside will usually drain to by the outside unit. Mine ended up draining onto the downstairs roof so go into the spouting, inside unit will only make moisture when on cooling or dehumidifying mode.

Not sure on the other aspects of the install, but the gap on the outdoor trunking that they have sealed with silicone is probably from the non flat cladding. If you want a tidy hidden install then it usually means ripping the lining off to run the piping, which means multiple visits for the aircon installer, and getting the wall re-stopped inbetween. Most people want the cheapest install which is what the market tends to offer.

The existing hole in the wall, looks like where a light fitting used to be? Appears to me that the heat pump is on the same centreline as that.

My exterior unit drains in a similar manner. No cause for concern there.

If you can't laugh at yourself then you probably shouldn't laugh at others.

Looks fairly typical to me. The water outside is completely normal, if you're getting water inside that's not normal.

I've measured it, and it's 32.5cm on one side from the heat pump to the window frame and it's only 28cm on the other side (you can see it on the photos).

Which as pointed out is probably where the studs are. The unit has to be secured to something in the wall.

Theres many reasons it might not be centered. For instance the point at the back of the wall unit might have the pipes go through the wall right where a wall stud is so it had to be shifted over 40-50mm to clear it.

The metal plates that go behind the indoor unit have a crapload of holes for mounting and several exit points for the pipes so I don't think that is the reason. When mine were installed they were able to center them exactly where I wanted them with no problems.

Was it asked to be in the center of the gap?
