"One hour for a new water heater" for a NEW one. If its a few years old, Id wait about 2 hours or so. That way it wont get cold while you are in the shower, and it can refill at the same time that it dispenses.
Usually about an hour.
depends on water pressure, but it should completely fill in 15-20 minutes. the water should be hot in another 20-25 minutes if it has been run completely empty.
depends on the gal size and btu of the heater. look on the panel and it will tell you the gals and btu. also is it gas or electric, single element or double. most 40 to 50 gal heaters will recover in about 25 to 45 mins.I AM A MASTER PLUMBER LOCATED IN TEXAS. Hope this helps.
15 minutes to half an hour.
If you burn a peanut it will keep aflame for a long time underwater, and boil the water
Usually about an hour.
Around 3 hours
depends on the wattage of the elements along with the temp of the cold water but i would guess an hour or two
To heat up a tankful of cold water will take about an hour initially. Once it's hot, the heaters will automatically come on when temperature drops a bit .
Anywhere from 6- 35 hours. Lol. No it should take around 2 hours
An immersion heater is used to heat water for purposes such as bathing or showering. The amount of hot water produced depends on how long the heater is switched on for.
Ususally about an hour or so...
You can not get heat from cold water, The engine has to run long enough to get the water in the engine HOT. That is were you get heat from HOT WATER-- Coolent
400 k BTU - But it depends on the gas line size feeding the heater; how long that run is etc. The larger heater will heat the water quicker thus cost for heating will be less ( than if you used a 250K BTU)
It depends on the how many degrees you wish to change the water and the wattage of the heater. Obviously a 1500 watt heater will do it faster than a 1000 watt heater. You might want to begin by looking at the heat transfer formula: heat in joules equals mass times change in temperature times specific heat of the material (water in this case).
Less than 3 minutes! It shouldn't take that long
In the long run a Rheem Tankless water heater will save you money in the long run by heating the water faster and you will have to run the water for a shorter amount of time for it to heat up.
