  1. I fitted the heater, the pipework and the showers, I can assure you that the showers are metal, mainly chromed brass in fact - I imported them from the UK as I couldn't find decent quality thermostatic units at the right price in Thailand. Only the last 150mm of pipe is metal - copper in fact. The rest of the pipework is standard PVC for the cold and PPR for the hot. It wouldn't matter if all the pipework was plastic - a leak of electricity in the 'wet' side of the unit could be transfered through the water to anyone touching the metal parts of the shower and thereby acting as an earth. I don't particularly want to be an earth . There is absolutely no way of getting to the metal parts without removing at least one tile, probably 2 - unless I want hideous earth cable or trunking running down the walls of my newly built bathrooms - no way. Incidentally, for the benefit of anyone thinking of using the PPR plastic hot water pipe system: If you are using it on a new build or the system you are planning is in the open, that should be fine. However, if you are retro-fitting or installing pipes in hard to get to places - import a push fit system or use copper. Much of my pipework is in a suspended ceiling. The PPR system uses an electrically heated arm with varying sizes of interchangeable spigots fitted to it. Basically, you push the pipe over one side of the spigot, and the joint over the other. Hold them there for a few seconds then pull them off and push them together - its almost like plastic welding. You could do with 3 hands, one to hold the arm, one for the pipe and one for the joint. On the floor, you can just about manage it or get someone else to hold the arm for you. Working in a suspended ceiling from a ladder is a completely different thing - I had burns all over my arms, I wouldn't recommend it.
  2. Is there any need for you to be so pompous? It would be a fair guess that you drive an automatic car - do you know how an autobox works? I'm a mechanic, I do - because its my business to know. I also watch TV but I have no idea how a TV works. I chose this form of water heater on recommendation from the seller who is a friend and visited 2 users - one who runs a restaurant running the same type for 4 years and reckons it cut his electric bills by 2/3. Some people don't see the point in having hot water in Thailand some do. Some are happy with electric showers - some are not. I wanted constant hot water at high pressure, available at all points with low electricity consumption. So far, for my needs, this unit is certainly giving me what I want. Although I undertstand the heat source principle, I don't know exactly how they work, I don't need to, I just know that in comparison to other forms of water heater, they provide reliable hot water at a reasonable price. However, I'm guessing there must be some form of supplementary heating as the unit will heat water up to 60 degrees (and it does). The outside temperature is around 30 - 35 daytime. In any case, if there is any risk of electricity coming into contact with water, I want to be as safe as possible. It may well be that this unit doesn't need earth bonding but I'd like to have that confirmed by an electrician. To that end, the unit is very similar, if not identical to this: https://cripton.com.sg/products/air-source-heat-pump/domestic/#.XcmU9dXgrIU
  3. Question for someone either qualified or with serious electrical knowledge. I recently installed a full hot water system in my home - the heater is an air source heat pump. I presume that there is a heating element somewhere that heats the 200l storage tank. The heater is earthed and I intend wiring an additional earth rod to it. However, I stupidly ommitted to bond the metal parts of the showers and kitchen sink to the house's earth circuit. I'm faced with removing tiles in order to correct this but is their an alternative? The heater unit is currently plugged in to a normal socket but it would not be difficult to wire it in to a dedicated circuit which, if my thinking is correct, would allow the fitment of an RCBO. Would that be adequate? I suspect that the only safe way is to both sort the earth bonding and power the unit via an RCBO. Although it means removing tiles which I really don't want to do, its not that bad because the bathrooms/showers are back to back and the tiles are very large. The last 150mm of the supply is in copper and I should be able to get to that on both showers by removing the tiles on just one side.
  4. Up to others what they do but I always have at least 20k cash and a return ticket. I don't have hotel bookings as I don't need them. If I had any problems at the airport I would also refuse to sign the form they try to use to deny entry - I believe that form is an admission that you don't have the required 20k.
  5. A lot of you guys are confusing noise with the regulations on emissions - hardly surprising due to how the article is written. However, EURO4 is not about noise - its about emmissions so its not only the exhaust that matters. The bike as a whole must meet the required standard which may mean re-design of the combustion chambers and injection system etc. etc. A noisy exhaust, whilst usually not improving performance at all, without a remap etc. (you just think it does), does not necessarily mean more pollution.
  6. It sounds to me as if you may be on one of the many 'Private Water Supplies'. My girlfriend's house in Korat had the same problem until I discovered that city water passed right outside her gate. It cost about 3500 baht to connect into that and was done within 10 days - problem solved. Do you know if you are on a state water supply or a private company one?
  7. All of the I.O.s give different stories and none of them appear to fully understand the rules - whether they be official or unofficial. Case in point: I travel to Thailand every eight weeks and stay for approximately 2 weeks. I've been doing that for quite a few years on a variety of visas and exempt entries. For the last 12 months I've entered on 2 more or less back to back METV's and have not had any problems other than a few occasions when the I.O. has studied my entry stamps closely. However, every time I read a story about someone being turned back I worry and have now asked Immigration what my position is likely to be 3 times. Each time the officer has looked at my stamps and said I'm fine as I leave after 14-16 days. On Wednesday evening after going through immigration on my way back to the UK I went to the Immigration counter and asked again as I've been told (unofficially) that I am unlikely to get another METV when mine runs out in December. I'll be travelling to Thailand in January and I'm hoping to enter on a 30 day exempt and again 5 weeks later for a friend's wedding - hopefully exempt again. After a little breathing space I plan on applying for another METV. The (female) I.O. I spoke to seemed very vague but said I'll be fine as what they are looking for is people who exceed 180 days in a year (I don't) and people who have overstayed. She also stated that due to the amount of entry/exit stamps in my passport, it would be better if I avoided land borders (I rarely use them). She advised me that I will be OK on visa exempt entries in January and March as the 180 days resets on 31 December. I don't trust that - I'll do an exempt in January but I'll get a new METV for the March trip. During the conversation I mentioned a friend who travels in and out a lot - he's married and up until now has entered on a 12 month Multi Entry Non Immigrant visa based on marriage. His visa is almost up and if he applies for a new one in the UK he will only be granted a 3 month one as UK applications must now be done online and the 12 month Non O (marriage) is not available with online applications. This officer said that 12 month Non O's have been stopped at all embassies and consulates and only 3 month ones were available regardless of where the application is made. I haven't read TV for a while but as far as I know that is untrue and only the 3 embassies/consulates that have converted to online applications have stopped the 12 month Non O's. To the best of my knowledge, unless things have changed recently, Savannakhet in Laos certainly still offers 12 month Multi O's based on marriage. The Non O based on marriage has nothing to do with you, I realise that, my point is to illustrate that even the I.O's don't know the rules or what is going on. All I can advise you is to make sure you have the required amount of cash on you + a return ticket. It wouldn't do you any harm to have some credible documentation proving that you work in the UK as the suspicion seems to be that those that enter often, do border runs and stay more or less long term are entering to work in the black economy. In your case I would certainly invest a a METV.
