The cost is set by the power, 9 kW, and the length of time it is used. This heater would use 9 units (kilowatt hours) for each hour it is switched on. Depending on the price the utility company charges you for their three phase rates times the length of time will give you the answer.
The cost to run a halogen heater depends on its wattage and the electricity rate in your area. For example, a typical halogen heater uses around 1,000 to 1,500 watts. If you run a 1,500-watt heater for 5 hours at an electricity rate of $0.13 per kilowatt-hour, it would cost approximately $0.97 per day. Always check your local electricity rates for a more accurate estimate.
What it costs me to run a heater does not depend on how much you are charged, but a 1500 watt heater would use 1500 watt-hours or 1.5 kWh for every hour it is run. Run for 24 hours it would use 36 kWh, also known as 36 units.
To calculate a cost in kW/h a time interval has to be stated. How long is the 400 watt heater going to be on in a 24 hour period. You also have to state what you are being charged from the utility power company per kW/h.
A standard cartridge heater usually requires between 1000 and 11,500 watts to run. They run on 120 or 240 volts and one can find more information on the Chromalox website.
From the details this is probably a UK question. It would use 60 watt-hours of energy every hour, which is 0.06 kWh or units of electricity, and that would cost around 1p.
how much an hour to run a oil filled heater
To answer this question the voltage of the heater must be given. I = W/E.
The Amana 12000 BTU Energy Star Room Air Conditioner with 11260-BTU Heater is good.
Propane heaters cost less to run per hour.

The cost difference between a tankless water heater and a traditional tank water heater is typically higher upfront for a tankless water heater, but it can be more cost-effective in the long run due to energy savings and longer lifespan.
To calculate a cost in kW/h a time interval has to be stated. How long is the 400 watt heater going to be on in a 24 hour period. You also have to state what you are being charged from the utility power company per kW/h.
You constantly need hot water
Single phase can't be turned into 3-phase by any reasonable means. But on the other hand resistance heating is fairly straight forward. If only the fuse rating is high enough it might be possible to rewire a 3-phase heater to run from a single-phase source.
It is more economical especially for running motors. Most motors start much better with 3 phase service. It also takes less current than single phase for a motor to run, therefore the power meter spins less for electrical cost.
it cost 50$
No, not really. The two hot legs can be opposite legs of a 120/240 V split phase power source. You still do need a protective earth ground, however, but the heater itself does not require a grounded neutral to run.
