Hi Authur,
How are you this is Tony from cssolar in Spain, we have spoken before.
How are sales ?
I now import from Audary New Energy, I have found pre heat swhs work very well here and are suited to the poor local water quality.
Working hard to promote the use of solar water heaters here , I think in a few years they will become popular like in China when people realise how much energy they can produce and save !
Best Regards
Tony
