Pressure expansion can cause pipes to rattle. This gives your hot water heater the ability to fluctuate with pressure

Yes, it serves both purposes and to be honest I have not installed it, because I mainly bought it as a back-up in case my present one quits.

I'm pretty sure it's main purpose is for heat protection. However whenever I use it, it does leave a shine to it as well. It's like a two in one. I use it everyday with my chi straightener and it works great!

It may be just the thing. And if you don't like how it looks, you can always, you know, use it for its intended purpose!

I'm not sure I understand your purpose but I can say that it has a very rich look to it. The lid opens to the storage compartment which is fairly large. I think it can double as a "coffee/cocktail" table as well. Hope this helps.

The purpose of the valve is to prevent back flow into the house...it is a one way valve so it cannot have flow in both directions.

It's mainly for looks. I bought it to use in a play that called for a spy glass. It really is mainly for looks.

It can be used for many different purposes. Usually I use it with a backup program called CrashPlan to do continuous backup.

Just to warm up food. It does not get hot enough to cook on. It is made for sabbath observant Jews to heat up food without it actually cooking more.

The main purpose of this thing is to mine BTC, or any other SHA-256 based coins like namecoin, peercoin. It cannot mine Scrypt based coins like litecoin. Other than mining, I don't think it can do anything else; and with today's bitcoin difficulty, this thing is useless for mining bitcoin.

I tossed it. I think it's to keep the plastic cover in place. Likes mold or casing for the casing. Lol

It serves no purpose other than to be cute. It's supposed to be the panda's belly button. :)

It's just for protection. It has a fuse, varistors, thick wiring, etc.. in it.
