Multi Point Water Heaters- Advice on model.

[Formaleins]

Wonder if anyone can tell me the difference (other than just over 1000 Baht) what the differences are between Stiebel Eltron water heaters - Model DDH 8 and the DHC 8 - Both are rated at 8KW, one is a bigger unit than the other, none of this really makes any difference to me, both have 5 year warranty, but electrically I cannot seem to see what the difference is other than the case / size.

 

If anyone has either of these and can post pro's and con's I would be grateful. 

 

I have been using a National 10KW multi point for over 10 years until last weeks electrical storm when it lost its low power boiler (The 4KW heater died, but the 6KW boiler pot is still working - I tried to get a replacement 4KW pot but everyone tells me it is too old, despite Panasonic selling an almost identical model.)

 

Anyway, I am going to buy one of the Stiebel units and give it a try as 8KW is probably ample for our use, 10KW is probably overkill and causes all of the lights to dim and the fans to run at half speed.

 

Thanks!

I just changed out a Stiebel for a cheaper Thai brand (forgotten the name sorry and I'm at work so cannot check)
The Stiebel was rubbish, noisy when activated and really low water pressure when running hot. Fitted this last one and its vitually silent on activation with a much better flowrate of hot water
Thought I was doing the right thing by paying that bit extra at the time but for me at least not so......

Thanks for that! If this one turns out that bad, I will probably look around to try and fix the National. I will be buying on Lazada, so they will get it back sharpish if it is not up to the job. Did you fit an inlet filter? If so can you tell me what brand / where to get one? Cheers.

No inlet filter but my tank water is filtered and settled before the house..

After reading what you said, I checked a few reviews online and it seems that what you say about the flow rate seems to be a common complaint. I have cancelled this one and gone for the 8KW Panasonic instead, a little more expensive but the National one I have has been excellent so I will stick with what I know. Thanks for your advice, I might just be lucky and managed to dump a lemon!
