Hi all,

I had my installation from GC today.

Just some clarifications:
1) the 1/4" written on the insulation tube refers to the copper pipe diameter?

2) insulation of the 3 different copper pipes are lightly pressed against each other when encased in trunking and slightly bent at corners, is that ok?

3) As its the first time the aircon compressor is running, how long should it take to cool a typical size room?


Thanks & Regards,

Jeremy

Hi all, comparing mitsubishi starmex and daikin which one will save electricity in the long run?

My in law hse is using daikin, everyday on for more than 8hrs for 2 unit and the electric bills is abt 100++. But then nowadays many going for Starmex, not sure which one to get.

Some qns too:
1) my living rm size is 7m×3.2m, what is the recommended size? Will be installing a door at the kitchen, mostly will be on only during meal time.

2) for combined bedroom, is it better to get 2×9k btu or 18k btu? Larger btu will use more electricity?

Thanks alot

Hi,
Recently found out that my 8yr old aircon is leaking gas (took 2 days or so to finish up a fresh topup). So decided to replace my current Toshiba System 3 - RAS3M20S2AX plus 3 x RASM10SKPX.

Looking at Mitsubishi Starmex for ease of maintenance. Any recommendation for compressor combo to replace the above as well as advice on insulation and piping requirements.

7m long don't have any kitchen door at all, just go for 18hp more sufficient.

My house using ME startmex for 2x10 daily using around 10 hours & 13k at living room daily usage around 4 hrs, for my electric less than 100 per month.

Also we have using daily for cloths dryer heat pump and water storage tank too

Hi Kimsim,
From the Mit StarMex pdf brochure, it says StarMex can reuse R22 pipes.
Does it means non-inverter aircon change to starMex inverter using R410A doesn't need to change copper pipes?


should be year end..

can download here for current package :

In b4 your contractor did with better grade of copper pipe thickess g22 or g23 still can be reused, just have to use Aircon gas flushing out the existing oil before to install new Aircon.. Part of it the only Aircon man would answer you

I see. Thanks. The contractor tell me starmex will consume more electricity than Daikin. So still in a dilemma which one to get.

In paper yes, in term of usage ME more coolest than Daikin, that is why enegy saving more prefer on ME at all

Daikin capacity is lesser than ME for all time if temperature to control room to room from ME Starmex maybe just require on 25C with low fan speed, but Daikin needs set to 24C with 2nd fan speed to suit as ME same setting.

End out ME more efficient than Daikin.

Against if i am the seller deffinelty I will push on Daikin right

had an installation by gain city 1 mth ago. rainwater will seep in from the condenser unit thru the gaps between the pipes. the technician came twice to add silicon but i doubt it will workp as the pipes goes up to the connector where it is much higher. hence water will still flow down due to gravity. anyone faced this problem before ?
Anyone can advise? e technician says if happens again he will come and do the pipe again. Will there be any complications or anything I need to watch out for?

Nothing much u can do about it. If the problem do occur ask them try to put a piece of metal plate right above the hole.
what if he comes and say to redo the piping ? its ok to redo the piping right ?

I'm looking for around 6-7 sets of wall mounted aircon for my new office..

any sales person or representative feel free to contact me at 90019690.

important thing for me is warranty period.

1 year is no go, prefer those with 3-5 years.

thanks!

Im installing a 4 system all of it for Rooms only


Mitsubishi Electric:
MXY-4A28VA / 4 X MSY-GE10VA (System 4)
Fan coil capacity : 4 x 8,530 Btu/hr
All on capacity : 4 x 6,397 Btu/hr
$3,745.00

with 3/8” insulation, copper pipe gauge 23 and 16mm PVC drainage piping


and from what i read people say HDB 3/8 its more den enuff right? then the all capacity it says 4 x 6,397 Btu/hr meaning 6379*4 =25588 meaning my compressor btu so litle?
