Bubble Wrap
In winter, bubble wrap can work as a natural insulator for the rooftop tank. The air inside the bubbles provides insulation, and wrapping the tank in two or three secure layers prevents cold air from reaching the tank’s surface, keeping the water warmer for longer.
Cover With Tarpaulin
Dew and cold night air make the tank water chill, especially when they is kept in the open terrace. Cover it with a tarpaulin, a wooden shade or a small tin roof. This prevents cold drafts from directly hitting the tank and helps maintain the internal temperature. Besides, most people in rural areas also use old sacks or thick cloth for the insulation of tanks.

Paint The Tank Black
This is a natural and scientific method. Paint the tank black, dark blue or dark brown as dark colours absorb heat more readily, allowing the tank to warm up gradually throughout the day as it sits in the sun. A single paint is all you need.
Position To Absorb Maximum Heat From Sun
If your rooftop receives ample sunlight, position the tank where it can soak up the maximum amount of heat. The sun’s warmth will naturally raise the water temperature, making your morning bath far more comfortable.
