To made House use electric heater which element is better?
The best element to use is a 3 phase electric heater that has a guard over the element protecting you from brushing against the hot part and stopping the element from starting a fire if the heater is pushed element down onto the floor
How much breaker load Amps required for 31 kw?
Impossible to say without more details. It depends entirely on the voltage of the supply and whether it's single-phase or three-phase.
What kind of breaker and wire size do you need for a for a heater that is 208 V 19 A 4100 W 2 wire 1 phase?
If the heater has a specified branch circuit rating with the manufacturer's information then follow that. If not then assuming it is to be run more than 3 hours per day: 19.7 A x 1.25 = 24.6 A Next size standard breaker is 25 A (see NEC 240.6) So you will need #10 AWG Copper and a 25A 2 pole breaker.
My electric water heater is reading 120 volts on each element is this correct for 240 system?
IT depends, You should read 120v on each element, but instead of reading from hot to ground on each element you need to check voltage across both elements and read 240v... so take your meter and put one lead on one hot and the other lead on the other hot of the element and you should read 240 if you dont your only getting one phase to your hotwater heater. What that means is your house has two different phases of 120v coming in, we call it A and B phase. on your panel you have breakers that are numbered on the left side 1,3,5,7.... and on the right 2,4,6,8... reason being breaker 1 and 2 are side by side left to right and are on the same phase and as you go down the panel it alternates phases 3,4 B phase. that why when you see a breaker that is a 2pole or a double breaker there ontop of one another like circuts 1,3 or 2,4 cause loads or appliances that require 240 volts it has to be 120v from both phases A,B to get 240v.

Why do ionic crystals conduct electric current in liquid phase or when dissolved in water but do not conduct electric current in the solid phase?
because of the gravity or Magnetricity
What circuit breaker rating do you need for a 3 phase electric motor?
The circuit breaker is sized to the full load amps of the motor times 250%.
When a single phase supply connect to a electric heater short circuit not there why?
The electric heater is basically a resistor, designed to have the right resistance to draw the required current. So a 2 kW heater designed for a 230 v supply is really a resistor of 28.8 ohms, so when it's connected the current is 8 amps and the power is 2 kW.
If I use a three phase electric ac and heater is it more economical that using a 3 phase gas ac and heater?
Well, as far as I know, there is no 'gas' A/C. The A/C will be electric, regardless of the type of heat used. Whether electric heat or gas heat would be more economical is really dependent on your electric and gas utility rates and the efficiency of the appliances involved.

What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.
How much breaker load Amps required for 31 kw?
Impossible to say without more details. It depends entirely on the voltage of the supply and whether it's single-phase or three-phase.
Does a two phase heater need a two phase thermostat?
Most electrical equipment are either designed to work on Single phase (two wires) or Three Phase (three or four wires). Two phase equipment are non existent today. A single phase heater will require a single phase thermostat while a three phase heater will require a three phase thermostat.
What would full load amps be on a 480volt 3 phase 90 kw electric heater be pulling 36 amps per leg?
46 amps
If you have a 3 phase and 120 volt per phase electrical source how would you connect a heater element requiring 208 volts?
Answer for USA, Canada and countries running a 60 Hertz supply service.It sounds like you have a three phase system to connect to. If it is 120 volts from phase leg to neutral then the three phase system is 120/208. To connect the heater to a 208 supply on the distribution panel connect the load across a two pole breaker. The amperage rating of the breaker will depend upon the wattage of the heater. Amps = Watts/208 volts.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Do you need a neutral to install 480 volts 3 phase heater?
If the heater is rated as a 3 phase 480 volt heater then a neutral is not needed. If the voltage stated is 277 volts three phase then a neutral is needed.
What is the purpose of the 110 V single phase breaker?
The job of a breaker is to limit the amount of current that is applied to the size of wire that is connected to the breaker.
Can a 2 pole breaker to protect 1 phase circuits and 2 phase circuits?
Probably
