I bought a Racold Solar Walter Heater (250 ltrs.) from MultiImpex (Sole distributor) on 12-April-2006 in Bangalore (Invoice no.121) considering the reliability of the equipment and the Racold’s credibility in the market. However, I am disappointed to see the equipment not functioning properly and poor quality panels. Their technicians tried to rectify and resolve the issue however with no results/failed to rectify. And I regret having made the decision to invest in this product and services.
There seems to be serious technical problem with the equipment installed at my place. It’s been only two months and the copper fins on both the panels are turning to green due to oxidation. This shows how poorly the black chrome coating has been done inside to save the cost. After several calls I received new solar panels on 18th Aug 2006 from the distributor which were worse than my old panels. The fins had been damaged and we could see few leakage marks and the joints were already green due to oxidation.
I sent those brand new panels back. I have also noticed other solar water heaters available in the market, performing excellently which in fact are cost-effective too - 40% less than Racold. Having experienced this, I am really disappointed and also caused a lot of nuisance to me and my family.
