    100% correct, bike or car driving. You MUST believe that every other bike or car on the road is there to harm you and be ready to avoid any harm, and dont ever get distracted

    That philosophy applies everywhere. Just more so in Thailand.

    I prefer to take the train when travelling in Thailand. Generally the middle carriage, on the assumption that sufficient energy should be absorbed by the locomotive and front carriages when they inevitably hit a truck or car whose driver decided to race the train over the crossing and lost. Why not the back carriage then you ask? One must acknowledge there is the odd time when another train driver plows into the back of a stationary train (which I could be on) while taking a comfort break through the side window, at the same time contemplating his last visit to a house of ill repute thereby failing to see the stop signal and the stationary train ahead.

    In this case caused by break failure yet again. Or at least the failure to apply them, which in Thai is the same thing.

  2. I have thought of using dependant thai child visa when I retire next year.

    What is the opinion of you visa gurus out there? Is it easier to obtain than the marriage or "retirement" visa in regards to paperwork, requirements etc? Paperwork was never my strong point. The deposit criteria is not a problem.

    Also is it worth using an agent? They seem to charge around 40K baht to do it. Some have said that they can set up a bank account and I dont even need to deposit the 400K or 800K into the account. How can that work as it suggests something dodgy to me. Are any of these agents licensed by the government or just all freelancers?

    The bank account issue has always confused me (Im getting old) as it seems very catch 22. You need to open an account to get the visa but you need the visa to open the account.

    Am I missing something here? Is it a problem with my logic or just a product of the slow deterioration of my ageing brain cells?

    Any help will be greatly appreciated.

    That depends largely on the size of the systems. location of the outdoor unit with respect to the fan coil unit and whether or not you require the system to be driven via a tarrif different to your power outlets.

    Some installations will have sufficient capacity on the power outlet circuits to handle to extra loading.

    Most installs these days are covered by combo circuit breaker elcb by law and maximum demand in final sub circuits is vastly different from a few years ago.

    That plus the majority of the RAC systems are screw compressors (quieter) inverter type given the compressor ramps up and down in speed depending on the heat load.

    Starting of these is much less demand on the cabling as opposed to the old problem when they were "bang" online run-of-the-mill compressors.

    I think you meant to say scroll compressors not screw compressors.

    You are not correct.
    Even Thai AC installers understand that water runs downwards so do not run the exhaust water pipe horizontally and since it is usually run with the other pipes (they are pumped or use pressure) they all run downwards allowing water to flow out. Also ugly?8C4BDE74-0328-42AC-868A-32524A29463A.thumb.jpeg.ae265ce17bb4d99e5e12824bee182995.jpeg

    This is an example that proves the point that your statement is wrong.

     

    You need approx 25mm per metre run minimum. Your pipe duct looks about 1.5 metres so you need roughly 37 mm fall, otherwise you will get build up from the general dust and detritus that accumulates on the coil. I doubt there is that much fall looking at that picture.  This will cause warm moisture laden air to condense onto the drain pipe and eventually saturate the pipe insulation and help to grow mould. Hopefully the drain line was insulated and hard pvc was used rather than flexible drain hose which will form "waves" and trap water.

    I certainly would not have that duct on my inside wall. To me it looks ugly but I accept you see aesthetics differently to me.

    I assume when you say(they are pumped or use pressure) you are refering to the liquid and suction refrigerant lines. The smaller (liquid line) will be around 2,500 kpa and the larger (suction line) 800 to 900 kpa when operating, assuming R410a refrigerant.

    Could you please elaborate on what you mean by this statement?

    The drain generall follows the pipes through the wall to outside and is hidden in the pipe duct and can drain into the garden or into a container. If the inside unit is attached to an inner wall with no direct access to outside the drain must then be ran along an inner wall to an outer wall to outside this is not only ugly but is prone to clogging due to the horizontal run of the pipe. The alternatives is to install a pump that either pumps the condensate through the ceiling and inside the roof space to outside or through the roof. This means you have the potential of rain leaks through the penetrations possible drain pipe leaks onto the ceiling combined with a pump that may introduce extra noise and will require frequent cleaning of the indoor coil, drain pan and pump to prevent blockage and overflow.

    One odd thing to be aware of is you will probably see displays of and  recommendations for Mitsubishi AC units.  There are actually two Mitsubishi entities selling AC units: "Mitsubishi Electric" which is more consumer grade and "Mitsubishi Heavy Industries" which is more commercial grade, however, they do overlap.  Consumer grade usually means more features, commercial grade tend to be beefier.  I'm not saying one is better than the other but something to be aware of.

    Good point. The reason I specified Mitsubishi Electric.

    Very good advice here, thanks Hugh Cow. I was actually thinking about something like a multi split, a double, there's a brick wall separating the bedroom and loungeroom so a double split - one for bedroom and one for lounge would be excellent....with the compressor out on the back balcony (all the units with AC have the compressors on their back balconies, that's how we can tell who has AC...just look up at all the back balconies.)  

     

    All this info I'm getting here is valuable. BTW: everybody who is giving me info, I'm copying your posts and saving all your info in a text file for easy access later.

    Just remember the 2 pipes from each indoor cooling unit must run back to the common outdoor unit when using a multi head split system. If you have one cooling  unit on each side of the house it can be a problem with the pipe run and can look ugly on the outside and it may be better to run two separate systems.

    A couple of tips. Most use a plastic duct cover for the pipes on the outside wall. The cheaper ones deteriorate from UV after a couple of years and need replacement. Make sure they use one with high UV resistence. A little more money now will save a lot later. Make sure the insulated pipe is sealed with silicone at the outside end, or over time moist air ingress along the pipe as it travels along the pipe between the pipe and insulation due to there being a cooler lower pressure inside, will gradually saturate the pipe and cause dripping and deterioration of the insulation over time.

  8. A rough guide to capacity is 400 watts per square metre of floor area. Split airconditioners will only do one room. The amount of filtering into a second room is negligible at best. As you have a long electrical run a multi head split might be better. This has one outdoor unit serving 2 or more indoor cooling units so only one power line required.

    Mitsubishi electric seem to have the best wrap from installers regarding reliability and parts availability.

    Panasonic are good and have good parts availability in Thailand but I dont know in Australia. Brand does matter! Some techs call LG aircon the anti christ of airconditioners well others come and go and have little to no parts network. 

    N.B. I would reccomend you have a qualified cert 3 tech instal the aircon. Australia changed licensing and many installers are electricians or plumbers who are not allowed to service the unit if it breaks down. Their knowledge is very limited and many do poor installations that can  cause expensive problems later. Remember the indoor cooling units need to be installed on the inside of an exterior wall for drainage purposes Otherwise they will need a drain pump to pump water to the outside. Many of these drain pumps block easily and require quarterly maintenance which is an added expense.

    FYI. I have a small interest in a aircon company in Thailand and the company is an authorised panasonic and mitsubishi dealer. I have been involved in the refrigeration / aircon industry for over 40 years in Australia.

  9. Sorry if this is in the wrong place mods but I'm not a good navigator.

    I know this is a forlorn hope but can I take my beloved motorcycle to Thailand? It is a 2003 model 1100cc. I have heard it is really difficult. Is there another way? Say to Malaysia or Cambodia and then take it over the border? I am willing to bear a fair amount of cost to do it as I've had it a long time and I hate to have to part with it.
