Warm water comes though a facet because you have a boiler or anything else to heat up the water.
Usually from a hot water tank.
If your outside faucet is not producing water, it may be frozen. To thaw it out, you can try using a hairdryer or heat lamp to warm the pipe. Be sure to turn off the water supply to the faucet before attempting to thaw it.
The part the water pours out of, usually activated by a lever in houses (perhaps one for cold water, one for warm water) and sometimes in public bathrooms.

Your hot water line needs more insulation probably. It sounds like your hot water is cooling before reaching that faucet. It may be that the one faucet is not able to turn all the way to hot until you adjust the faucet (usually in the handle) of a 10 year old or newer faucet.
Odds are that the cold water lines to the faucet you are trying to use are shut off but the hot water lines coming from the water heater are not. That is why you have hot water but no cold water.
Water in open ponds and lakes will lose heat to the colder air above it. Water in pipes exposed to the air, or beneath frozen ground, will also lose heat. In cold weather, water from a hot water heater must first warm all of the pipes it travels through before it reaches the open faucet.
To clean a satin nickel faucet, use a soft cloth or microfiber towel dampened with warm water and mild dish soap. Avoid abrasive cleaners or scrubbers, as they can scratch the finish. For tough spots, a mixture of vinegar and water can be effective, but rinse thoroughly afterward to prevent any residue. Always dry the faucet with a clean cloth to prevent water spots and maintain its shine.
