Electric Hot Water Storage Systems....chiang Mai

[mikey88]

I would love some help. Does anyone know where (location and directions if you can) to buy a small....say 80litre... Electric hot water system for my house.

I want the storage type. I don't want Thai style low flow on the wall things and I don't want solar.

I just want a plain old electric hot water system. Then I'll put in some copper pipes to the kitchen, laundry and bathroom and I'm happy.

I have a feeling people will say why do you want hot water in the laundry and kitchen (my friends have said it to me already). The answer is I want to wash my towels and sheets in hot water (just like the old days) and the same for my kitchen dishes.

If anyone can help with advice and direction I will be very grateful and hope to return the favour someday.

Old Mike..

Hom Pro has been selling them for years. Super Highway between Sii Yaak San Dek and Macro on the same side as Macro in what used to be the Careforre shopping center but is now a Big C or something else.

As the other posts have said Homepro, Global, Home Market etc

I purchased a HW heater tank 2.5KW about 3 years ago price 16K, I think its 100L

I had the HW heater mounted in the roof space and ran copper pipes into the various rooms, I set the Temp at 60deg

Generally you mount the HW heater on a wall either vertically or horizontal

That's a big he,p...thanks fellas...my 80 litre unit in my home country seems to be quite economical.... Can you say the same here?

Could anybody give an idea as to running costs. I know it's a very broad question. There may only be one person (me) using the hot water...

Thanks for taking the time to reply.. Cheers....

I have a 120L tank and run it through a time switch 5 hours a day at this time of year, 4 in the summer. It provides sufficient hot water for kitchen and bathroom for a family of 4 so you can figure maybe 12KwH (ie 12 units) per day at your meter rate. Most modern washing machines are cold fill only so unless you've got an older one, the water won't come from the boiler.

Yes, most waher machines are cold fill, they have a water heater inside to heat the water to the correct temp

Some waher machines require a seperate heater which are expensive as they have a large KW - 6/7

I also use a timer on the electrical heat assist on my solar system, on only an hour in the early morning this time of year. Before I had a smaller tank (about 70 liters) at another place and had a switch on it, turn the switch on in the morning, have a cup of tea and in 15-20 minutes the water was hot and usually lasted until evening then switch it on again for a short time.

Why do you still want this old style of water heating's with a tank, this is not needed anymore because there are instant hot water providers to be fitted in the bathroom, kitchen or any other place, with pipe connections to any rooms of your choice which then have constant a hot water supply at any time.

I have two of them one upstairs and one downstairs and they provide hot water in all the rooms (with taps and sinks) it is a perfect hot water supply, the water tap handle controls the heat, on the extreme left it is very hot indeed like boiling, the heat can be reduced by turning the tap slowly into the opposite direction as needed.

The most efficient hot water supply equipment is from the German company SIEMENS the name is Siemens Automatic and is available in several CM department stores

HomePro and Global, tip with Homepro though, they lie about delivery dates, just to get your money and it is like pulling teeth out to get it back. I prefer Global now.

the great thing about these is that they don't have the large 6000W draw downs that most peoples 5/15 Single phase power supply struggle with..

Be careful because many of the "plain" auto washing m/cs do not have an internal heater and only have a one inlet solenoid valve for cold water. If that is the case then connecting the washing m/c to the hot water supply is the best bet.

Agree that they are a good idea, but as Thai Dreamer has said they draw about 6kw so really need a new stand alone supply running to them and that can prove a problem.

You might have to excuse me because I am a novice at home renovation here... Xylophone seems to be saying that I can get a full flow hot water eli very with a wall unit inside the bathroom or kitchen?

Am I understanding him right? What's your opinion?

The reason I wanted to go with the storage system is that I want full flow and hot.

Is here another cheaper way of getting a full flow (western standard) with hot water?

Advice appreciated.

Home Sukkhapan on the first ring road have a good selection of water heaters and systems.

Hi Mikey,

If I am on the same wavelength as personchester, then he is describing a wall unit not dissimilar to the ones which are installed in many Thai rooms for showers etc, where the water is heated as it flows through a coil element, rather than heated in a tank with something akin to an immersion heater which we remember from the old days.

The wall unit works from the mains water supply (from your pump so should provide good pressure) and has a 6 kW heater in it, so it is quite powerful and will heat the water successfully even if it flows through at quite a rate. It does not store water and measures approximately 14" x 12" x 3" (sorry about the pre-metric measurements).

Some people fit one upstairs to supply hot water to the shower and sinks, and the same downstairs with the added addition of a supply to the laundry.

The main problem with these units is that they do require a separate power supply able to cope with 6 kW, and very often these have to be installed on a stand-alone basis because generally nothing you have in the house at the moment will cope with that load.

Now I don't know what type of house you have but it is also worthwhile remembering that the majority of Thai houses only have one water supply to the sinks, shower units and laundry, so to run a separate hot water supply/piping will be one hell of a job unless you intend to use the existing piping for your hot water which will mean that every tap/outlet in the place will be supplied with hot water. Having said that, the good thing about these small units is that you can control the temperature of the outflow on the unit itself each time you use it, rather than having preheated water sitting in a tank somewhere at a constant 60°.

I hope that makes sense!!

Not to imply that the answers here haven't been helpful but you might try looking in the DIY Housing Forum where there are some stressed out people in the middle of their building nightmare projects. In particular, there are a few regular contributors who are very helpful in the electrical department which sounds like maybe where you are heading.

Mikey88 quote: " Then I'll put in some copper pipes to the kitchen, laundry and bathroom and I'm happy".

Just read your original post again Mikey and noticed the above which is good thinking whichever way you decide to go. The reason I say that is because of the plastic piping which is used in the majority of Thai built houses, and the fact that many installers do not use glue on the joints (or if they do they don't use enough) and these can leak after a while, even more so if hot water was being pumped through them!!

Once again, good luck.

You've all been very helpful .... Thanks lads... Mike

Why not use one of the excellent German heaters which run on LPG?

This avoids a large power surge heating water. The one I had in Indonesia came at a good flow as I had a water pump, and the hot water output was quite good. There is no reason why this could not be extended to provide hot water for a kitchen or a washing machine. Just make sure your washing machine can take hot water,(i.e. the plastic fittings are rated for hot water) and if it's a cold water only model, then you'll be using your hot water for all the rinses too.

I had two LPG cylinders, one for the cooker, one for the hot water. If one ran down, then it's a quick swap over until the next bottle is delivered.
