Does the effency of a water heater increase if the supply water temp rises?

Naturally it will become more efficient. And why is that? Simple. A water heater raises the temperature of the source water. Therefore if the source is at 10 and you need it to heat up to 60 , the unit has to heat the water up by 50degrees.
Should the source be at say, 40, the unit will only have to heat the difference between 40 and 60. Since the thermostat(cut-out) will already be at 40, the heater will only raise the temperature by 20, thus working less, and naturally, WASTING LESS energy, which is an increase in efficiency.
An example
10deg heated up to 60deg will take 40minutes (20 gallon tank)
40deg heated up to 60deg will take 10--15minutes

Why would a heater work better near the floor than on the ceiling?
Because heat rises.
Does the resistance of heater coil remains same when current flows through it?
Typically resistance rises with temperature.
Why is the top of water heater extremely hot hot enough to melt the rubber red and blue bushings around the in out plumbing?
Because heat rises - the top of the water heater will always be hotter than the bottom.
When voltage increase then current will be?
it depends on what type of load. Motor amperage will drop off as voltage rises. loads such as lights will increase amperage with voltage rise.
What would a long and thin pipe do to the flow of the water?
Increase the pressure.'ABSOLUTELY WRONG.Pressure cannot be increase by reducing a pipe diameter.If you have 60 PSI Flowing thought 2" pipe and decrease the pipe to 1" you still have the same 60 PSI supply pressure.If the above lie was true then why not have the city main be 60" pipe reduce it to 2" to give "pressure" to 47 high rises?What is actually happening your INCREASING VELOCITY LOWERING Volume and doing NOTHING but possibly lowering the pressures do to friction losses
What is the most efficient airflow for a garage heater?
Heat rises so a bottom supply will work best.
Demand rises and supply is constant?
No. If demand rises, then supply falls. Transveresly, if demand falls, then supply rises.
If the cost of input rises what will happen to supply?
there is a shift in the supply curve when the cost of input rises.
If price rises what happens to supply for a product?
it rises
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.
What happens to the equilibrium price and quantity when demand rises less than supply rises?
When price and quantity demanded rises less than supply rises then shortage of goods create.
When demand rises and supply remains the same equilibrium price will... and equilibrium quantity will?
If aggregate demand rises and aggregate supply remains the same, the quantity supplied which increase. Consequently, the equilibrium price will increase, as will the equilibrium quantity. LOOK AT LINK BELOW: http://upload.wikimedia.org/wikipedia/en/thumb/e/eb/Supply-demand-right-shift-demand.svg/240px-Supply-demand-right-shift-demand.svg.png As you can see, if demand increased from D1 to D2, the price level would increase from P1 to P2, and the output would increase from Q1 to Q2. Hope this helps!
When the air rises does it increase or decrease?
increase
What causes supply to grow as price rises?
law of supply
What is the relationship between the law of supply and the supply curve?
it always rises from left to right
What happens when a electric heater is switched on?
The heater element is a coiled wire resistor that draws enough current to supply the intended amount of power, which might be 1.5 - 3 kW. Quickly the temperature of the wire rises until it reaches an equlibrium where the heat power conducted away by convection is the same as that draw from the power supply.
Sentence with supply and demand?
Her supply of tight sweaters increases the demand for her as a date on the weekend.
