The jacket (lagging) stops the heat of the hot water from escaping into the atmosphere.
This could be due to a blockage in the hot water line or a malfunction in the hot water faucet. Check for any clogs in the faucet or the hot water pipe. If the issue persists, it may require a plumber to inspect and fix the problem.
There are a few possibilities why. Troubleshoot asking yourself these questions: Is the hot water heater switched on electronically? Is the stop cock switched on? Are there air locks in the line? Is the hot water heater connected?
Hot water bottles work by filling them with hot water from a kettle or tap. The heat is then trapped inside the rubber or silicone bottle, providing warmth for several hours. The hot water bottle is placed against the body to provide therapeutic heat for comfort or pain relief.
The hot water pipe is not clamped properly. When the water flows through the pipe when you open the faucet, the turbulence makes the pipe move and bang against what ever it is not clamped to properly.
Yes, cold water can drain faster than hot water due to differences in viscosity and temperature affecting flow rates. However, the difference may be minimal and can also depend on factors such as pressure and pipe material.
Hot water pipe rust first as compared to the cold water pipe for the same chemical composition of the water.
Cold water pipe.
It is a thermal jacket that fits over the tank to insulate it
a fiberglass insulation blanket that has a plastic jacket, they sell them specifically for hot water tanks
That's just how long it takes to get the water that is sitting in the pipe out. Unless you have a circulating pump on the line so that there is always hot water at the faucet, it always takes a bit of time for the water to get hot. The hot water is in the tank, not the pipe connecting it to the faucet. There is nothing in the pipe to keep the water hot.

Your hot water pipe may be frozen due to a lack of insulation or exposure to cold temperatures in unheated areas of your home. Even though the water inside the pipe is hot, if the surrounding environment is cold enough, the pipe can still freeze.
Hot water recirculating pumps work by circulating hot water from the water heater to the fixtures in a building, such as sinks and showers, through a looped pipe system. This helps to keep hot water constantly available at the fixtures, reducing the time it takes for hot water to reach them and saving water that would otherwise be wasted while waiting for hot water to flow.
Check pipe size for hot water or if galvanized pipe used, pipe could be clogged inside with rust and scale.
There is no special PVC pipe. CPVC can be used for hot water applications or in my opinion just use PEX pipe.
The water is probably frozen in the pipe
