When hot water is delivered from a mixer tap it becomes cloudy, cold water delivered from the same faucet is not cloudy. Please help with an explanation and possible fix

Possible accumulation of sediment in water heater. How long since you flushed your water heater?

This v"cloudy" water. Is it caused by air or sediment? Have you removed the aerator and checked the screens? Let me know, Tom

Could just be dissolved air that comes out at room pressure. Fill a glass and let it sit a minute or two, what happens?

You can flush your water heater? This one is at least fifteen year old, they made them good then

Not sure what you mean? It might be air as it sort of disappears. Sort of like a head on beer, but there is also a taste factor

It will slowly become clear sort of like a head on beer, the detergent also becomes cloudy when washing the dishes.

This has only happened since I replaced the faucet, I wasn't aware of it before then and not aware of it in other hot water taps

Don't know how faucet would affect taste. Sounds like dissolved air, commonly found in hot water. Your HW tank is under 50# or so pressure and air can be dissolved in the water. When you open the tap, the water comes out and is at room pressure, the air comes out. Notice how CO2 comes out of a beer or soda bottle when you open it?

You can flush your water heater?
Yes. At the bottom of the water heater should be a drain valve. Connect a garden hose to it. Point the hose into a sink or outside. Open the drain valve.

Do not close the cold water input stop valve.

Let the water run until it is clear. The force of the water should flush out any sediment. This should be done at least yearly. Of course after 15 years the sediment may have accumulated so much that it blocks the drain valve.
