^ it is a multi-point heater for up to three hot water outlets. Brand is Fagor.
They have loads of these instantaneous multi-point water heaters in HomePro and similar shops, just don't confuse them with the electric showers as they look the same.

you can actually connect as many outlets as you like to those, but if you use more than one at a time you will not get very hot water
Hello to you (all the experts)
For a four bathrooms with tub, what would be a better heating system.
especially if guests decide to enjoy the bath two or three at the same time.
Thank you for your advice.
^ Depends on how many hot water outlets you are planning on. You don't need hot water in bathrooms with no shower/bathtub. You can just install a normal cold water tap in bathroom sinks.
If you have tubs in all the bathrooms as you indicate you will need a large tanked electric or gas system so you can store heated water as well as supply. It will also require a powerful electric pump so all the rooms have decent water pressure. You will also have to factor in a hot water inlet for the kitchen and anywhere else you want hot water.
You could install more than one water heater as many have a limited ability and a maximum amount of recommended outlets.
It is going to cost a lot in Thailand for this kind of installation as most Thais go for cheap fittings and cheaper electric showers even in newer houses. Proper hot water is a relatively new phenomenon here. Our bathroom renovation has run close to 70,000thb and that is just a shower, toilet and sink in a 1.5m x 4m room.
get a decent solar water heater and there will be no problem supplying all of them
Thank you Khun Nostradamus for your insight,Originally Posted by Nostradamus
do you have an idea of market price for a good heater system?
I would need a good one with multi-outlet for this house with 4 Bed rooms,
but then another building with the kitchen...! I am quiet spoiled with european way of using hot-water to clean any grease!
Thank you DrAndy,Originally Posted by DrAndy
will a good solar system, cover and could provide adequate hot water for all I mentioned? any idea of recent pricing ? Thank you again
Can anyone tell me if electricity used in Thailand is generated with the star, or the delta system. This has vital quincequonces for safe earthing.
In my condo, it seems that all earths (such as they are) are tied down to the neutral.
We had the same system in Ireland, & I get the same problems - a voltage sits on the neutral, so my desktop computer tickles me if I touch it.
How will this effect the ELCB of my shower - there is already a voltage on the earth/neutral.
I do not use the shower, but winter approaches.
sorry, missed thisOriginally Posted by siam
anyway, yes, a solar system can cover any demands as they come in different sizes and can be linked
mine, which is 170l of scalding water, was about B40k plus around B10k for fitting, delivery and things
quite cheap compared to some systems out there
if not very recent, there is probably no earth systemOriginally Posted by fridgemagnet
there is a safety cut-out which is meant to save your life if anything misconnects
No safety cut-out here, and with only 2 wires going to the main switch, I'm not sure what type of device would offer good protection.
It is 3-phase Wye (Star)Originally Posted by fridgemagnet

Star (Wye)/Delta has little to do with safety & more to do with voltage.
See the following info: Earthing system - Wikipedia, the free encyclopedia
The info in the above link is very rough but it does provide an insight into earthing systems & the differences between them.
In Thailand, the most predominant system is IT. Some areas may be TN C+S.
I have never seen a TT system in Thailand.
The earthing system MUST be realised before any kind of protection can be appropriately used.
Idiots! I'm surrounded by idiots!
Thanks for the info.
I will now search to try & see what earthing system this old condo uses.
A Residual Current Device (RCD) might be handy there. Residual-current device - Wikipedia, the free encyclopedia
It senses imbalance, meaning YOU are a conductor to ground -earth.
Wye or Delta makes no difference, you can ground either. In fact, the secondary side is considered a separately derived system and needs to be bonded to ground. When you derive a neutral on a Delta transformer, you pin one secondary leg to ground and squint when you throw the switch!
I was always taught that a country needs to ground everything, or nothing. I'm no engineer but I would want a GFCI on each leg, an RCD, and would want a water tight electrical compartment on my water heater. I'd run a wire to a driven rod, or metal pipe that is known to run down into the earth to derive a ground reference.
That's just me, YMMV.
No surprise that people are dead from this. Seems all I see in Thailand is type IT but without the user-end ground. In the states we ground all metal with a grounding conductor. The neutral is called the grounded conductor.

Take a look again at the wiki link you provided.Originally Posted by EssEffBee
An IT system has no Neutral from the transformer to the consumer!
The most common system in Thailand is the TT system.
The wiki link does not expose the true extent of IT connections.
Try this link, if you are technically minded;
Earthing Systems
Page 56 is enlightening.
Currently we are having a house built in the north part of Thailand, near CM.
I too do not love theese heating things in the bath rooms.
Searching for alternatives bring the solar panels up.
So far i do not manage to find prices near the range you mention, to be more
specific more than twice is quoated for a small household system with 4 outlets, all
at the same end of the house. 3 bath + kitchen on 2 stores.
Can you provide some information on companies to contact please?
Thank you.
