I consider my decision to buy Kaltech Energys solar water heater one of the best choices I have made for my new house.
I installed the water heater last month. Even though it was raining all day last month, enough hot water was available. I bought 210LPD and connected to all toilets, kitchen and work area.
When someone go for a water heater, we hear lots of negative comments and apprehension from people around. There will be no hot water during rainy season when it wanted the most is the prominent one among these. Also there were apprehension for going for not-so-popular brand. However my experience with Kaltech solar water heater proved it all wrong.
One thing to be taken care of when plumbing is done is that take shortest route from water heater to the taps. When distance is more, it takes more time for hot water to reach the tap after long interval.
I am completely satisfied with the performance of the Kaltech water heater as well as their service so far.
