No, not all water heaters are 240 volts. While many electric water heaters, especially larger models, operate on 240 volts for efficient heating, there are also smaller units and some models designed for residential use that operate on 120 volts. Additionally, gas water heaters do not rely on voltage as they use natural gas or propane for heating. Always check the specifications of the specific water heater model for its voltage requirements.
Answer for USA, Canada and countries running a 60 Hz power supply service. For electrical panels the proper terminology is L1,L2,N. N is for neutral and it is this wire that is grounded. The voltage measurement from the L1 to N will give you 120 volts. Also from L2 to N will give you 120 volts and from L1 to L2 will give you 240 volts. Single pole breakers in the panel board starting at the top, alternate between L1 and L2 all the way down to the bottom. These breakers all have 120 volt outputs. If you plug a 2 pole breaker into two slots then you get 240 outputs because L1 and L2 are adjacent to one another.
When equipment is run at a lower voltage than it is designed for, it does not operate correctly. A light will glow dimly or not at all, a heater produces much less heat. Electronic equipment may not function at all.
For alternating current, and assuming the supply transformer is properly grounded, you will have 240 volts to ground. 480 volts; single phase will have Line1 and Line2, both with 240 to ground and 480 across both Lines : three phase will have Line1, Line2, and Line3, all will have 240 to ground, and 480 across any two Lines. Same is true for 240 volt service, 120 to ground and 240 across. 120 volt service is 240 volt service using ground as neutral.
A central water heater serves multiple fixtures from one unit, while individual water heaters provide hot water to each fixture separately. Central water heaters are generally more cost-effective and energy-efficient for larger homes or buildings, while individual water heaters offer more control over temperature and usage for each fixture. Individual water heaters may require more maintenance but can prevent the loss of hot water to all fixtures if one unit breaks down.
Regarding the question of "Why isn't there voltage drop in a 240 volt system?" The smart alex answer is "because no current is flowing." Only if no current is flowing can there be no voltage drop in any circuit. All conductors, even supercondutors, have resistance and this resistance will produce a voltage drop when a current is flowing through the conductor(s). 240 volts is used over 120 (or 12 volts) because it reduces the current reguired for a fixed amount of POWER (watts). Therefore, the conductor size can then be reduced to reduce cost, size, weight or to improve flexibilty.
What kind of appliances? All electric ranges and dryers are 240 volt. You can get them anywhere appliances are sold.
Nope. Not the one you get from USA.
In America, Canada and other countries using a similar 60 Hz electrical service, few appliances which use mainly electronic components require a 240 volt plug outlet for everyday homeowner use.On 60 Hz services 240 volt outlet plugs are very large and are intended for use with large aplliances such as clother dryers, ranges, water heaters, etc.Another answerActually, my husband and I bought a tanning bed several years ago to use in our home. We had to call in an electrician and have one 240 volt outlet put into our workout room. There are, however, tanning beds that run on everyday outlets. We chose one with some extra features, which required more power.There are many countries outside the USA, Canada, etc. which use a 50 Hz electrical service so that 220-240 volt power is standard in all homes. Hence domestic electronic equipment that is not operated on batteries mostly uses 220-240 volts in those parts of the world.
One of the advantages of electric heaters over gas heaters is convenience. All homes are equipped with electricity, but not all homes have gas. But there are a variety of types of heaters, such as space heaters, hot water heaters, or furnaces. With electric heaters, there is no risk of becoming overcome with fumes.
All water heaters should have a pressure relief valve, otherwise they could burst.
All my experience with rotary phase converters have been in converting 240 volt single phase into 240 volt three phase. They all were hard wired into their respective systems, so my answer is no.

A normal household temperature for water heaters is around 132 degrees. They can all be adjusted from about 120 to 150.
Some water heaters may use magnets in water treatment systems to help reduce buildup of minerals in the tank and piping. This can help prevent issues such as scale buildup and increase the efficiency of the water heater. However, not all water heaters use magnets for this purpose.
Ford OEM block heaters are all 600watt (5.3 amp x 115 volt). aftermarket heaters are available up to 1000watt. (1 kilowatt).
No, but if you ever switch to an electric stove you will have problems getting a 240 volt circuit to that location. I would go ahead and install a 240 volt outlet at that location if this is new construction. Costs very little and you will be all set for the future.
First of all there is no common three phase 120 volt service. There is in North America a three wire 120/240 volt single phase service. That being said, if you want to change a 120 volt source to 240 volts it must be done with a transformer. Its classification is a step up transformer. The primary side of the transformer H1 - H2 will be connected to the 120 volts. The secondary side of the transformer X1 - X2 will be connected to the 240 volt load. The transformer is sized by the current required by the 240 volt load.
