It will cost about 30p per hour, 10-12p per Kw.(On a normal tariff) when actually heating the water, as it will cycle on/off via the thermostat when the cylinder is fully heated, so depending on how much hot water you actually use, count on about 40-45 pence average over 2-3 hours.

I found this information on a website. Hope it helps. Remember your immersion heater will be heating up at night, and assuming you have the Economy 7 electricity tariff, it will be heating at the cheaper "night rate".
It is surprising how expensive some appliances can be to run especially if they are used on a daily basis. So how much will that mean in terms of running costs?
To work out the running costs of electrical appliances multiply the rating by the amount of time it is on to give the number of kWh (kilawatts per hour). Then multiply the cost per kWh (look at a recent electricity bill or tariff leaflet for the appropriate figure - we used 6.6p for the example below).
Wattage divided by 1000 x time used in minutes divided by 60 = kWh
kWh x cost in pence = cost
e.g. A 900 W vacuum cleaner used for 15 minutes: 900 divided by 1000 x 15 divided by 60 = 0.225 kWh
cost = 0.225 x 6.6p = 1.5p
Therefore using a vacuum cleaner for 15 minutes costs 1.5p
The table below shows the typical rating in Watts for some of the more common household appliances:
Cold Appliances
Freezer 150
Refridgerator 100
Heating and Hot water appliances
Immersion heater 3000
Instantaneous hot water 3000
Oil filled radiator 500-2500
Radiant heater/fire 1000-3000
Storage Heater 2000-3000
Wet appliances
Dishwasher 3000
Tumble dryer 2500
Washing machine 2500
Cooking appliances
Electric hob 4 rings 2500
Grill (alone) 2500
Kettle 1800-2500
Microwave oven 800
Toaster 1050-1360
Lighting appliances
Light (common incandescent) 100
Light (compact fluroescent) 20
Home entertainment
Portable radio/CD 18
DVD Player 15
TV widescreen 70
TV standby 5
Video cassette player 35
Playstation 50
Miscellaneous
Blanket (under) 60-120
Blanket (over) 150-350
Fan extractor 75
Hair dryer 400-1200
Iron 1200
Vacuum cleaner 900
How can I use this information?
Most modern appliances will label how many watts they consume. This can be used as a guide if you need to buy a new appliance or simply identify which appliances are costing you more money to run.

all the immersion heaters i,m familiar with were used by the military, and ran off kerosene , cost now days would be around $3. a gal would run 4 hrs on 1 gal

What size? Divide the watts by 1000, times the hours per day it will run, times .09 cents. That will be close to the daily cost. In stock tanks around here, it would be 750 watts, divided by 1000, times 24 hours, times .09 or $1.62 per day.

A lot...When you have it switched on,look at your meter and see the wheel spinning...
Anything that produces heat ie kettle,shower immersion heater etc

They're usually 3kw, so it would be three units at whatever your unit rate is per hour.
