I never trust cvnts who give all this detailed info but no prices...

makes me think it will be an ott price so I don't bother to click the link...

if they put the price it gives me confidence in them and i'm much more inclined to pursue the subject...

maybe because the product is imported and they don't have them on stock all the time. The price changes a lot depending on the size of order from abroad (shipping charges depend on the weight of the consignment).

I was always under the impression that ships charged by cubic meter.

Solar water heaters? Why not run your pipe around the garden a bit - that'll get the water hot. The water from my well comes into the house at about 35 C during the day - the well is a couple of hundred metres away and the pipe is not protected from the sun.

Unfortunately, that means I can't get a really cold shower during the day. Do they make solar powered water coolers?

Absolutly correct.They charge per cubic meter or 1000kgs.There is no way that this type of stuff would be more than 1000kgs to the meter..more likely 200kgs/M3

many thai use electric water heaters, especially winter time.

that particular solar water heater is sophisticated and (probably) expensive. Even a flat shape water tank above the roof or on the balcony will do the job for the average size family

**DrAndy** · 10-12-2006, 03:04 PM

I want solar heated water in my new place

I reckon a simple cheap solar panel is good enough for Thailand, with a decent sized collection tank. No need for expensive sophisticated stuff, even in the rainy season. As my roof will not be suitable for the panel, I will mount it on a slab in the garden, and pump the water when needed.

**dirtydog** · 10-12-2006, 05:44 PM

Best way is to have a few solar panels to generate the heat, south facing of course, these feed a well insulated tank, the last one we done had spray on foam insulation and 3 layers of traditional 6inch insulation wrapped round it, it really does need this much insulation, each layer helped keep it about 2 degrees hotter, now the tank and solar panels are made into a sealed unit, ie the water only circulates between the tank and solar panels, so you now have a tank of say 1,000 litres of boiling hot water which can only be pumped thru the solar collection panels ( ie it is a sealed system), into this you need to run coiled half inch copper pipe from the water mains supply for your house, ie so you get as much copper in the tank and then returns out of the tank to feed your hot water supply, so when your hot water is turned on the water travels thru the pipe that is in the tank of hot water and then onto your hot water taps, the pipes to your hot water taps need to be copper and insulated, the stuff they use for air con insulation is fine.

**Eliminator** · 10-12-2006, 08:09 PM

And most of the construction in Thailand has piping for hot and cold lines. NOT. New construction would work but other than that, you're talking about putting in all new piping to handle it.

**DrAndy** · 11-12-2006, 10:54 AM

DD, are all solar heating units indirect, or do some just run the cold water into the tank as you use it?

**dirtydog** · 11-12-2006, 01:15 PM

Must run cold water into the tank as it is used, this one we had specially built.

**DrAndy** · 12-12-2006, 03:55 PM

yes, I thought it sounded special

and expensive too, I bet

**dirtydog** · 12-12-2006, 04:53 PM

Yep, but most places don't have 8 bathrooms, 2 kitchens and a heated swimming pool, getting one made up would be cheaper than buying a ready made unit for a normal house plus would keep water heated longer over long cloudy weekends.

Except during cold winter mornings, which is when you most want some warm water.
