It should be hot, but the top should be hotter. You don't say electric or gas. ALL facts are relevant when we answer questions like this -don't with-hold information. -You want a good answer, give us ALL the facts.

What happens when the cold and hot water pipes are reversed on the hot water tank?
You will get warm instead of hot water. There is a tube inside the tank on the cold side that goes to the bottom of the tank and the hot comes directly from the top. Reverse them and you are going to get the cold water that settles to the bottom of the tank. It will not hurt the tank or anything, it just makes for poor hot water.
What insure that cold water is forced to the bottom of the water heater tank?
The cold water supply enters the tank at the bottom near the burner. Heat rises, as does hot water. The hot water supply is piped out from the top.
How do you clear mineral deposits on the bottom of an electric hot water tank?
You should shut the power off and drain your tank at least once a year to get rid of the rust and deposits at the bottom of your tank. Also, I would recommend to replace the sacrificial anode every five years. This will prolong the life of your hot water tank for years to come.
Why Cold water is supplied to the bottom of hot water tank?
That's where the burner is located. Also this keeps it from mixing too much with the hot water that rises to the top of the tank.
Should the vent on a gas water heater be hot?
Yes. It connects to the inside of the tank, where the hot water is. Heat from the hot water will heat the vent pipe by conduction. The top end should be much warmer than the bottom end, near the floor or outlet.
Is water heater rust harmful?
No, but it will wreck your hot water tank. Every tank should have the gas or electrical shut off, the water valve to tank shut off, and the tank drained ONCE EVERY YEAR!!! The rust buildup on the bottom of the tank enhances the speed of the tanks demise.
Why should the immersion heater be placed at the bottom of the storage tank?
It gets warm but only if the immersion heater is switched on. The warmer water will rise slowly and start circulating in the tank, so you end up with a tank full of hot water.
Why water is generally heated from the bottom?
Warm anything, air or water will rise. Cold water is put at the bottom of the tank through a tube inside the tank. The water is heated and rises and is taken out of the top. The inside of the heater is open, it is just a hollow tube. That is why the hot water gets slowly colder, more cold water is being mixed with the hot in the tank.
Can you drain a leaking hot water heater by running hot water in home?
No, you have to attach a garden hose to the fitting at the bottom of the tank. Often the tank will have sediment built up in it and the water will drain very slowly from this.
What do you look for when a duel element hot water heater does not keep water hot?
The question doesn't contain enough information. When you open the hot water facet, does the water come out hot, but cools quickly? If so then you probably need to replace the dip tube. The dip tube insures that the cold water is injected at the bottom of the tank as the hot water is with drawn from the top of the tank. Dip tubes are mounted in the cold water input side at the top of the tank. some times dip tubes break off at the top so when you start drawing hot water from the top of the tank the cold water is injected into the top of the tank and this makes your hot water cool quickly. The water will come out hot, but will cool quickly. Normally when the cold water is injected into the bottom of the tank (through the dip tube) it will displace the entire tank full/column of hot water out through the top of the tank before the cold water gets to the top.
Can you shut off the inflow valve to hot water heater for a day without harming system if so should pressure valve be left open and limited usage of hot water?
If you have a leak on the hot water somewhere in the house and the water input into the tank is not running, the tank will lose it's water. And if it is an electric tank, the elements will burn out. Gas hot water tank should be no problem. Pressure valve does not have to be open.
My water heater used to heat plenty of how water but now it only heats enough water for one 10 minute shower. What causes this?
It sounds like one of the elements inside the water tank is not working. There are two electric elements in and average size water tank. One at the bottom and one at the top. These two elements cycle between each other but only one is on at any given time when calling for hot water. Water that comes into a HWT looks like it comes into the top but there is a pipe inside the tank that delivers the water to the bottom. When the tank thermostat senses the cold water, power is applied to the elements, be it the top one or the bottom one. Because you have enough hot water for a shower I would guess that the top element is working but the bottom is not. The incoming cold water is not getting heated. When the top element is hot enough it should switch to the bottom element to start heating the water in the bottom of the tank. Sounds like this is not happening.
