A Dubai-based manufacturer of water heaters working from solar power has given an interview the Gulfnews. According to him, such water heater can pay off in just 2 years. The heaters use solar power instead of electricity and do not pollute the environment. They can heat 400 liters of water per day up to 90C. In addition, such water heaters almost do not require any maintenance. In Dubai, the largest sun-powered water heater is installed on the roof of one of the hotels, which has 220 rooms. The owner of the hotel reported a saving of about 100,000 dirhams on electricity bills.
