The sun works well for me.
Materials with good thermal insulation properties, such as vacuum insulated stainless steel or double-walled glass, can keep water hot for longer periods by minimizing heat transfer with the surroundings. Additionally, materials with high heat capacity, like ceramics or food-grade plastics, can help retain heat for a relatively longer time. Proper sealing of the container can also contribute to maintaining water temperature.
polystyrene
A double-walled insulated cup made of stainless steel or ceramic will keep hot water hot the longest due to its ability to retain heat and prevent heat loss. Vacuum-sealed tumblers are also effective in maintaining the temperature of hot drinks for an extended period of time.
A styrofoam cup can help to retain heat, but it is not as effective as materials like ceramic or insulated metal. Hot water in a styrofoam cup will cool down faster compared to using a better insulated material.
A double-walled insulated stainless steel cup will keep water hot for the longest period of time, typically up to 6-12 hours. It is designed to reduce heat loss through its layers, providing better insulation compared to regular cups. Vacuum-sealed bottles or cups are also good options for keeping liquids hot for extended periods.
PEX pipe will keep it hot longer than copper.

use insulation to keep the water hot for 40 minutes
keep it in a hot place
Because metal absorbs and conducts more heat then most other substances so it keeps it hot. Just like when you cook, you use metal pans because they conduct the most heat.

No, It doesn't. If you want to keep hot water hot for a longer time use a polystirene cup.
A double-walled insulated cup will keep a hot drink warm the longest. The insulation helps to trap heat and prevent it from escaping, keeping your drink hot for an extended period of time.

not sure but i think styrofoam or thermocol
