nakedmolerat: I came across this brand at our community centre. I'm surprised how cheap it is and it works really really well. I must say I'm terribly impressed and on par with Fujitsu that cost 2 - 3x more. I don't know about reliability though as it is new.


I can only speak from my 7 years experience in the industry 

I have never sold Gree but a retirement community in Hamilton the developer had fair few installed a few years later we pulled a whole lot of them out a few years later and replaced them with Fujitsus and the homeowners were much happier with there new units..

To say they are equivalent to fujitsu is like saying a Cherry car is equivalent to a Toyota. Cop, eer, noise compressor life support etc all better on any t1 brand

3 brand I would install in my own house: Daikin, Fujitsu and Mitsubishi. 


I have heard that fijitsu are a good brand for heat pumps. My issue with buying a  cheap brand, is that the install cost of either a cheap brand or a premium rand is likely to be around the same amount, it is just the hardware of the cheap one that is cheaper, so you are only saving on the hardware, and not the labour. Then if it doesn't last as long, it likely would have been cheaper to buy the more expensive hardware long term. Not sure about fuel efficiency and running costs on the cheap one vs the more expensive brands, but if you compare them to cars, the cheap chinese brands can be quite a lot less fuel efficient and many have lower safety ratings, than the premium brands, mainly because they are using older technology.In some case they are producing cars that were old models of premium brands, as they have purchased a license to produce those older models.

The efficiency is less about a brand's build quality than the design specifications of individual models. The Designer series from Mitsubishi and similar Daikin Zena aren't very efficient despite being from two of the best brands. Both brands have more efficient models.

I had a Fujitsu ASTGLUCA installed about this time last year. Whenever it gets below about 4 deg the thing really struggles to output warm air, it does but it spends most of its time defrosting, more or less useless on frosty mornings when you really want it the most. The other major pain with it is the 7 day timer programming. Its a nightmare. It is the most unintuitive method of programming anything I have ever used.

In the end I actually rang FujitsuGeneral and asked if there was a step by step guide to doing this because I just couldnt seem to get it right. They indeed had a guide obviously because I wasnt the first person (and no doubt not the least technical of people) to have problems setting up the timer. The "simple" guide involves 16 steps to set up Monday, then another 16 for each additional day of the week you want to do.

I am replacing 2 other heat pumps soon and they wont be Fujitsu.

Well, I wasn't very impressed with my gree heat pump this morning.  I woke up freezing this morning at about 7am, set it to 19 on heat mode and went back to bed for a couple hours.  When I woke up it was 24 degrees in the lounge.  It seems the heatpump doesn't switch off once it's reached the desired temperature.  Anyone have any advice?

Also I still don't know what those tree and house buttons too.  The button can set as tree, house, both, or none.

Go back to the company who sold it to you. Maybe it is faulty.

That actually made a little sense... it's the power saving mode, healthy mode, power saving + healthy mode, or "normal" mode.

at least it heats up! 

try choosing power saving + healthy mode and see if temperature rises above preset value.

also how/where did you measure the room temperature? the reading on your thermometer could be way different from the reading on the heat pump.

I have that exact heat pump in my place 

What area do you live in?

What size room is it heating?

Not sure, about 3.5 m maybe.

Yep to insulation, house built in 92.

It works fine above about 5deg or so.

Its possibly a tad undersized but not too badly 

Could be where the outside unit is placed

Mine works fine at -2

I don't work in the industry. But the price that they paid for $1000 with how well it work - i found that interesting (from end user point of view). It keeps the whole area warm. Noise level is equivalent.

Products do improves from time to time.

Im guessing that the heatpump "thought" the room was colder than 19deg. Even though it was hotter? Have read on another forum that if the hole for the pipes between the indoor and outdoor units hasn't been sealed properly. It will draw in cold outside air which the room temp sensor will sense. And it will then think the room is still cold.

So I have a bit of an update on my heatpump issue (making the room too hot).

The heatpump has a function called "I feel" which I hadn't been using.  Instead of taking the room temperature from the sensor on the unit, it takes the temperature from a sensor on the remote control.  This works well and the unit stops and starts as needed.  The conclusion I've reached is that the sensor on the unit isn't working well.  When the "I feel" mode isn't on and normal heat mode is used,  the unit detects a lower temperature than the room is.  The unit stays on at full speed for much longer than it should be.

I'm wondering if the location of the heat pump (floor based, in the old fire place) is the problem.  If the chimney wasn't capped, could the cold air behind the unit be throwing off the sensors?  I wouldn't have thought so as the sensor is on the front of the unit (according to the manual).  I've also noticed that there is no seal around the inside walls.  It's mostly tight but has gaps in the bottom corners: Pic1 Pic2

Would appreciate any thoughts anybody might have.

Small gaps can let through large amounts of air and more so when heat differences are involved. An open chimney could let plenty of air through. Closer to the floor will always be a lower temperature and more so if the place isn't heavily insulated.

Different heat pumps have different quality air filters which is another thing people overlook other than efficiency. They said on the last Fair Go that 70% of people just set their heat pump thermostat to maximum and most never clean the filters!
