I have installed recently Kaltech Energy solar water heater(150Ltr) in my home.
The installation was clean, tidy and with minimal interference to us and the installers had plenty of knowledge to answer all questions as the day progressed. All in all I am very happy with the whole installation and its system performance, and would definitely recommend KALTECH system to anyone who feels it would be suitable for them.
I would like to thank KALTECH team for their high level of customer care prior, during and after the installation of our solar heating system.
