    Only Friday we were told that the rain would ease?

    They never started here west of Udon Thani! the local medium sized reservoir has half the amount of water in it as it had at the beginning of the "rainy" season! ???? 

    Whatever the reason, be it grand solar minimum or someone forgot to turn on the tap, the weather patterns are changing, but I guess they always have!

    Matt black radiates more heat than any other colour. 

    Indeed but Dark matt surfaces are better at absorbing heat energy than light shiny surfaces. Dark matt surfaces are better at radiating heat energy than light shiny surfaces, Dark colours absorb a lot more heat than lighter ones because they absorb more light energy. In fact, the closer to black a colour is, the more heat it absorbs from light sources, therefore the energy is converted to heat up the water more efficiently as the water is cooler than ambient temp, with a radiator it is a lot hotter than ambient therefore will lose heat quicker. - something like that ????

    For THB 10000 you will get a nice Heater  to have a Hot shower if you want More you may have to upgrade your Wiring.

    I can get a hot shower now, I want a hot shower with volume and pressure - in the colder days, during the summer the water is too hot to get a cold shower!

    No pleasing some ???? 

    What power supply does that "heater" require? does it use the same water supply as a "multi point" heater?

    Also is the "spare" a multipoint (like your existing unit) or a "shower" heater?

    It's identical to the one fitted - "multipoint", as I said in previous post, first winter up here I replaced existing heater as i though it was burnt out - I was wrong!

    Add another water heater in series with your current one.

    As I said earlier, this is about adding an extra dimension of comfort to my life, not essential, not going to tear the house to pieces for the sake of an extra ~10 psi when I shower, wife has her own bathroom and never complains so what I have is quite adequate.

     

    It just so happens I do have a spare water heater! I'm guessing wiring them in series would pull more juice? be quite do-able if it was feasible?

    The water heaters are not inefficient, it is whoever thought that they can raise the water temperature by 10 ~ 20 or more degrees with a high flow shower and put in a 3kw or 6kw unit. 

    Yes - incredibly stupid of me, after 23 years in Thailand at that time, I only put in an 8 kw unit thinking it would be more than ample, sure you had that one covered. I never realised how cool the water got up here! ????

    Er - how do you know the element on the water heater is not stuffed?

    Got that one covered! exactly what I thought my first year up here! so i bought a new one - result = exactly the same ???? 

    it works great in the summer ????

    Not wishing to coin a phrase but "You cannae change the laws of physics Jim", 8kW (or about 6kW with your volt drop) will impart the same energy to the water (and hence the same delta-t) whatever the heater "technology".

     

    'Tis how it is I'm afraid.

    Yes, I get your point ???? 

    But! if the energy could be used more efficiently, though it appears we haven't found a way of doing that yet.

    My initial thought were that there was possibly a "storage" type of water heater that would be more efficient, I have seen the smaller ones but never looked into them, if you had a "reasonable" volume of water sat at a higher temperature, the colder water would take less heating/power - if that makes sense.

    Could you fit an immersion heater to that SS tank and set its thermostat to just take the cold edge off the water.

    Tank also feeds toilets, kitchen etc, so not really. It holds enough water for 24 hours normal inside household usage.

    Can you measure your supply voltage when the 8kW heater is operating? Power is a square-law against voltage the actual power of your heater may be well down.

    It drop's ~20v, (Note. heater is placed in one of the most inhospitable and cramped places in Thailand - or I'm old?)

    I can live with what I have, but do enjoy a hot powerful shower, (I have no hesitation spending money on myself ???? within reason!) 

    Not interested in ripping tiles off the wall for plumbing though, bathroom sits under a flat concrete roof that is filled with insulation so running power cables not practical or easy either. Gas not an option, too many negatives.

    I was hoping there might now be a "alternative" heater, new to the market, looks like that is all it is - hope.

    Well I had experience with Ebay and last was not pleasant - will not be returning.  Use Lazada, Shopee and even Aliexpress with very few issues.

    Pretty much my experience also, there have been a lot of delays with the "Controla Virus" agenda - but received everything I order from China, different story with goods ordered from the USA, Chinese suppliers helped - USA suppliers not interested!

    Seems that you need to "warm up" the water before it reaches the shower unit.

    That would work, but difficult to retrofit! would have to reroute water piping and would need another power supply, worthy of some thought - thanks.

     

    Water to the house is cool! doesn't travel far, no other houses around, goes into a smallish stainless tank that is painted matt black which helps a little.

  12. It's starting to cool off "up North" now, I never realised prior to moving up here how inefficient the water heaters are when cold!

    In the summer, water heater is barely required, the winter is a different story, still have hot water but just a good sized trickle from shower if you don't want to freeze, one thing I enjoy is a decent shower, especially when its cool!

    What are the options for "upgrading" without ripping down walls for rewiring? current "instant" heater is 8kw, which serves bath, shower and sinks.

     

    If your a "southern softy" & never ventured "up North" you wont comprehend - why! ????

    Clean the drains out , when you lay concrete foundations for new buildings add drainage to connect to present drainage system.

    When building walls to enlose a space , find out the lowest part of the enclosed space and build a drain outlet.

    When provided money to build and clean drainage , do it. Don't buy a new motor , it is not your money.

    Thats would be a revolutionary concept for Thailand to grasp - Honesty!

    Not going to happen ????

    His personal motto may as well be - I, Prayuth, promise to move Thailand backwards at a breath taking and alarming pace, and never, ever do anything to benefit the Thai people. I will continue to do everything I can to protect the elite, the super wealthy, the connected, and those in office, either in the police, my administration, or the army. The little man simply does not exist, in my consciousness, and it is all about the super rich, and the army. 

    Control the masses so the "elites' can continue to do exactly as they wish, you can apply that to virtually every world leader can't you? that's how they got the job, the illusion of Democracy, Technocracy - great tools for ruling add in Controlavirus and you have the perfect recipe, those good folks at Tavistock (social engineers) will and are coordinating, while the "Elites" sit back and chuckle!
