Watts = Amps x Volts for a resistive load like a water heater.
It's not recommended to plug a 240V 30 amp water heater into a 3-prong dryer receptacle. Dryer outlets are typically 240V with a different configuration that may not be compatible with the water heater. It's best to have a qualified electrician install the appropriate outlet for your water heater to ensure safety and functionality.
the simplest solution is by connecting two 120v 3amps heater in series , the same can be used directly on 240v. However the current drawn will still be 3 amps & Not 1.5 amps. The heater output power will be double that of a single heater running on 120v. ( or equvalent to two heaters operating on 120v. supply ) A more expensive method is to use a stepdown transformer which can be powered on 240v & connect the heater on the transformer 120v side. this method will consume approx. 1.5 amps from the 240v supply.
Yes, a 240v heater will work with a 220v output. The slight difference in voltage should not significantly affect the heater's performance. However, it is always recommended to check the manufacturer's specifications to ensure compatibility.
For the HE40M1A water heater, which typically requires a 240V power supply, you should use a minimum of 10-gauge wire for the circuit. This gauge appropriately handles the amperage needed for the water heater while ensuring safety and efficiency. Always consult the manufacturer's installation manual and local electrical codes to confirm the correct wire size and other installation requirements.
The breaker size for a 10 KVA electric heater would depend on the voltage it operates at. For example, for a 240V heater, you would need a 41.67 Amp breaker (10,000 VA / 240V = 41.67 A). It is important to consult with a licensed electrician to ensure the correct breaker size and electrical setup for your specific heater.
In North America it takes two "hot" wires to obtain 240 volts.
Installing a 240v tankless water heater in your home can provide benefits such as energy efficiency, cost savings on utility bills, continuous hot water supply, space-saving design, and longer lifespan compared to traditional water heaters.

Yes but you will not get the full watt rating out of the tank. Watts = amps x volts. Say the tank draws 20 amps. 20A x 240V = 4800 watts. 20A x 208V = 4160 watts. It will take longer to heat your water with less wattage.
In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.
What is the definition of voltmeter-ammeter method?
No. Sounds like a fairly hazardous thing to try as well. If it's to use a heater in the US, then buy a US heater at a lower cost than any adaptor that might do the job for you. If it's to use on a UK building site that has 110V but doesn't have 240V, it breaks all the rules because you end up with 240V where you shouldn't.

The size of the circuit breaker for a 240V, 60Hz garage heater typically depends on the heater's wattage. A common rule of thumb is to choose a breaker rated at 125% of the heater's full load current. For example, if the heater is rated at 4,000 watts, the current draw would be approximately 16.7 amps, so a 20-amp circuit breaker would be appropriate. Always consult the manufacturer's specifications and local electrical codes for precise requirements.
