If you are looking to buy a water hose that can be used with hot water then you should buy a specific heated drinking water hose. These hoses gently heat the water as it passes through the hose and are multifunctional; not only can you use them to transport safe drinking water to your RV but you can use them for bathing water too. Using a standard hose for hot water is inadvisable as the material might not be able to cope with the heat.
