Water storage heaters (Boliers)

[davureborn]

We often have no water, or insufficient pressure to make the water heater work, generally when I need a shower.
Has anyone got one installed? Do they need three phase  'lectrics? I don't remember seeing any on sale, where did you buy, and what brand?
Any good?

To solve your Water pressure issue, consider getting a Pressure Tank. Talk to Bob at RST as he know this setup.

And add a 1000 liter water tank in the mix (don't have to be that expensive) and then you can take a lot of long showers

At my house the  local village water supply was so poor that at certain times of the day only drips would come out of every outlet.  I got a water bore dug (Well), equipped it with a pump and turned the village water supply off.  I then connected the pump water into the existing line above the turn off valve of the village water supply and have sweet cold water with high pressure, enough to stand a hose up with never having to pay a water bill again. Such a simple process. No need at all for any storage tanks

I don't know enough about it to know if it was the best solution but......we got 2 tanks filled from the village supply and a pump and filter system. We have 2 electric shower units and pressure from pumps allows both to be used at the same time with no problems to date. All was fitted by Ruangshangthai.

Davu ... I have a 1000 litre tank that is constantly trickled filled from town mains.

On the outlet side of the tank (between the tank and the house) I have a Mitsubishi WP-155Q3 pump that pressurizes water into the house and exterior garden taps.

The pump is a normal 240v plugged into the house system. Three phase not required.

It's a simple setup that works very well. Plenty of pressure, even if several taps are running at the same time.

As mentioned by Freddy, Mr Bob at Ruangsanthai Hardware will happily set all this up for you.

Cheers

Ruangshangthai do have a water team who will visit your property. Tell them what you want and they will do a site visit and provide you with the different options and costs.

Thanks for the answers guys.
I still want a boiler, but will consider the Mr Bob solution which I had been putting off as the whole area around the part of the house where a tank might go is at present a complicated no go zone.

[iammike]

If you decide to go for a Tank, also consider an Underground tank. I have one (1600 Liters) and even when there is LOW water pressure from the mains it still trickles in.

Yes there are small electric water boilers available. You can program them to heat water at a certain time of day so you are not keeping it hot all day. Cost is about same as 4 of the typical shower heater but it will supply whole house if you want mixer taps in kitchen and bath. I'll find out more details and pass it on.

Global or Homepro sell the seibel tanks

I have been offered all the mainstream brands of water heater tanks and then the strange brands of dubious reputations. I picked these two posts from a building forum in Thailand that bear reading:

When we built a couple of years or so ago, I opted for a tank style hot water heater.  I wanted my rain shower to serve an appropriate purpose on cold "winter" mornings. If I recall, we bought a 35 liter German make -- and mounted it on an outside wall on our covered terrace.  It has worked out very well -- mostly.
 
A few weeks back the hot water side hose blew out.  Flooded the terrace (no real harm) but had Ms. Klikster hot-footing and scrambling around. Got the hose replaced with a (hopefully) stronger one.
 
Why I'm posting this is to warn folks.  The electrician who installed our unit told of installing a similar heater in a new build about the same time ours was connected -- a house about 20-30 km south of Khon Kaen.  But the guy (farang) wanted his hidden and insisted it be in the space above his ceiling!
 
So if any of you folks did the same, or know someone else who did, please let them know about the potential for some serious water damage.
​from a previous 2017 post​
​Most houses in our village use 150 L boilers from Stiebel. And we also had problems. They don't are very reliable, especially when not uses often. We had a problem with some models, which were replaced by Stiebel. We also had a major failure, after the technician has used a wrong hose, which was not suitable for hot water...
 
I also wound't recommend to put the boiler above the ceiling. This save some space - but creates a lot of trouble in case of a leak or a repair/replacement of the boiler.
 
I would recommend multi-point instant heaters. They are more expensive, but you are more flexible. We use 8 kW models from Stiebel for our kitchens and the guest bathroom.
 
We also have a heat-pump from Energy Master with 200 L tank. It is quite expensive, but very reliable since 2010. We first used it for the whole house, but no installed the heaters as mentioned above. The 200 litres weren't enough for the kitchen and with guests. We like (long and) hot showers and there wasn't enough hot water in the evening... :smile:​

Why, when living in a tropical country, would anyone want a water heater?

I understand the need for a tank and a pump but a heater???

[Freddy]

Tend to agree Starman. I haven't had a hot shower in over 2 years but both the wife and her daughter use hot water everyday. Even hottest time of year.

I had similar problem. Found that the reason hot water would not turn on was lack of pressure... I simply cleaned the inline filters on the intake side of Heater. You have to unscrew the water pipe supply to heater and clean it every now and then. These are very small filters and block the supply of water when clogged... If supply is not good enough then the hot water unit will not turn on.....  Worked for me...!

yes.I had to find this out also. The fact that the water supply seems to be turned off every afternoon doesn't help though! Thanks.
