Can we get hot water all 24 hours of the day?
Yes ! The advantage of the solar hot water geyser is that you get hot water any time of the day or night, and irrespective of the fact whether there is electricity or not! This is true, but is limited to system capacity- the maximum quantity of hot water that can be utilized in a day will depend on the system capacity. If you withdraw more water than the rated capacity, then the water might not be hot enough & Electrical back up provided in the system can be used.
