If you are talking about a hot water tank then the answer is no. If it is leaking from a fitting, it just needs to be tightened. If you can not tell where the leak is coming from, the water leak is the first sign that the tank is going to need replacing in the not to distance future.
The thermostat is broken and needs to be replaced. You need to disconnect the water heater until you can get it repaired to prevent over heating and a possible fire.
An electric water heater in a hot tank is called an immersion heater and many of those run at 3 kW with a thermostat to control the max temperature. Power showers use a type of water heater that heats the water at the point where it is used, without a tank. They run at 6-8 kW and are also controlled by a thermostat.
That's going to depend on . . . -- the starting temperature of the water -- the target temperature of the water -- how fast you want it to get there -- the efficiency of the heater you use
Not much of anything. Drip legs were quite common in the past, and many cities and engineers still specifiy their use. They are intended to capture any condensed water that may have been transported in the gas. If you don't have a drip leg, I'd not worry about it. I was flagged for this in the Borough of Magnolia in NJ and had to install one to obtain a Certificate of Occupancy. You can call the township you live in to see if it is required.
As you say you had to reset the circuit breakers, the water heater's heating element may have "died" by shorting to Ground or Earth. This could be the reason why its circuit's breakers tripped to cut off the power. Time to buy a new water heater...? <><><> Typically, you should be able to tell a difference as quick as 15 minutes or so, but it may take well over an hour or two for it to reach "operating temperature". Some electric hot water heaters, you can even hear them as they heat, and you typically can the gas ones. Your biggest variables, assuming you're not using hot water as it heats, is the amount of water that is in the heater, as well as the heating power the heater puts out into the water. Electrics are practically 100% efficient, but gas ones are not even close, but they do operate at higher heater temps and can heat the water faster. <><><> It takes about an hour for a fifty gallon electric water heater to heat up.
Not the best choice
If you mean drip leg, yes you can. Some local codes still want a drip leg installed.
It's because "hot-water" is a compound adjective, modifying "heater". It's not for heating water, it's for heating a house with hot water. There are many types of heaters that heat water, but only a hot-water heater is used for providing heated water for domestic use. A hydronic boiler also heats water, but it's only for use in radiators.The name "Hot Water Heater" is completely wrong for any use. There is no need to heat hot water. IT has always been "water heater". The term hot water heater has just been used for years because people don't realize the difference. It has always been WATER HEATER.The first answer is jibberish and makes no practical sense at all.
it died
raising the thermostat on the water heater
Check the heating elements in the water heater. These may be bad and need replaced.
In general a water heater will only last so long.The major problems are with the thermostat and the heating element.You'll have to replace the thermostat occasionally.If the heating element goes out it's time for a new water heater.
The gas water heater works through a principle of physics which is known as convection. The gas heater is similar to a water heater only that it has one heating unit.?æ
Yep. The water heater will warm up the area in which the water heater is located. You will find out later if it is sufficient heating.

Aside from heating water, pretty much nothing.
