Answer . [Note: There are critical safety concerns involved here. Read the whole answer!] . I'm no plumber, but I do know this:. You need to determine if your water heate…r is designed for side venting or verticle venting! . If installed improperly, the water heater may allow deadly carbon monoxide into your home and possibly cause a fire! . I think this one is best left up to a professional. Hope this helps.
a direct vent water heater is more fuel efficient (cost's less to operate). aside from that there isn't much difference, aside from not needing a double wall flue through the …roof on a standard gas water heater.
If the installer used CHEAP single wall flue pipe (sheet metal) and the heater is running for an extended amount of time YES it gets very hot and double wall piping should be …used when passing through any flammable area AGA , NFPA 54
yes it is fine to insulate the whole water heater from top to bottom and the first two meters of hot water outlet piping.
NO! This is a FIRE HAZARD. Manufacturers of all water heaters always install insulation around the tank then cover it with the sheet metal jacket. I have seen many times where… a person has insulated a gas water heater and the flames from the burner chamber escaped from the cover and ignited the plastic on the insulation blanket.

No, in general use a conductor will allow electricity to pass through it. An insulator will not. There are how ever some materials that can change between the two states.
Gas water heaters are internally insulated, and need air flow to burn the gas off safely and correctly. There is no need to insulate them, in fact it would be very wrong to do… so. Simply put pipe insulation on the exposed copper. Home depot has it in the plumbing section. Electric water heaters are different, and you can insulate them with a fitted sleeve sold at plumbing part shops, or most large hardware stores. be sure to insulate the copper as well.
makes the water stay at the set temperature longer plus keeps the water heater off longer.
Direct vent takes incoming air and discharge though the same flue as it is sealed combustion. A regular flue is strictly for the discharge of dangerous fumes. Se…e the NFPA 54 or national fuel gas code or the NBBI ,ASME section IV
I am not sure, but this is what I think... That's because the water is heated to less than 100 deg C (and a thermostat turns off the heating once this temperature is reached).… Still, most models have a safety valve in case excess pressure builds up.
yes they are
No, each must be vented seperately.
No, directly vents through to outside wall of building.
