the method or device needed would need to be compact, perhaps I could start by having something fitted to the bib tap end with the hose attached to that. All the other info still stands: fast heat over fast flowing, narrow water usig self sustainable energy like the sun or the water itself.... sounds vague? that's because this is simply an idea in my head - like a flux capacitor! I fell off the toilet seat and hit my head.....

thanks guys for all your help, much appreciated. there is no plan B. I said before this is something I'd like answers to the theory before it's worth taking to the next level. It appears that as of today, this can't be practically achieved.

sorry for the late reply. All my questions are simply to find out if in fact it is possible to heat water under these conditions. If the 'theory' answer is yes, then I can take it more seriously and move to the next level of finding someone (perhaps someone here?) who I can work with to create this. Is it, in fact scientifically possible to do this under these conditions?

I was thinking of something more self sustainable? like using solar energy, or even the flowing water itself? I realise this is a huge challenge, but worthy of more thought perhaps!

Copper pipe sounds more practical. in fact, if the hose was a large piece of copper by design, what could be done here to heat the copper?

thats one of the main problems - I have no idea if it is in fact possible to generate that heat over that distance consistently without the use of gas or electric. when I run a hose, or a tap in the summer it is warmer, we all know this. Is there something here that I could harness? natural heat sources, solar energy or something. what about a mini turbine of some kind. I don't have a background in science so I really have no idea.

so sorry, I meant *C, (its been a really tough week!) starting temp, I'd guess at around 6*C

the flow of water is 1cm is diameter, and can fill 2 litres in 8 seconds. yes, in degrees. does this help?

thanks guys, the flow of water, in this example would be through a standard diameter hose, and the speed of a conventional 'house tap pressure.' The theory is I would like it to get to around 70 degress or so. I would really like to entertain ideas that dont use gas or electric. thoughts?

Would it be possible to heat cold running water without using gas or electric sources fast and to a high temp? I want to heat cold water coming down a conventional hosepipe from the very 1st drop BUT the heating process would need to be done in the last 10cm or so. Has anyone got any ideas on how this could be achieved?
