Evening gents,
For those of you who use Immersion heaters regularly, do you claim back for your electricity used.
Cheers

Is the sun yellow?
It is a common misconception that the Sun is yellow, or orange or even red. However, the Sun is essentially all colors mixed together, which appear to our eyes as white. This is easy to see in pictures taken from space.
Rainbows are light from the Sun, separated into its colors. Each color in the rainbow (red, orange, yellow, green, blue, violet) has a different wavelength. Red is the longest, blue the shortest.
When we see the Sun at sunrise or sunset, when it is low in the sky, it may appear yellow, orange, or red. But that is only because its short-wavelength colors (green, blue, violet) are scattered out by the Earth's atmosphere, much like small waves are dispersed by big rocks along the shore. Hence only the reds, yellows, and oranges get through the thick atmosphere to our eyes.
When the Sun is high in the sky, the shorter waves, primarily the blue, strike air molecues in the upper atmosphere and bounce around and scatter. Hence explaining why the sky looks blue.

??? Do you not know where only window cleaners on here ;D
The longest wavelengths are also the weakest, thats why red is the first colour you lose underwater(from my scuba diving days)

So did you ;)

So how do you calculate the cost to heat the tank or rather for the period you have it plugged in.
Surely you need to be reasonably accurate to claim for this.

your price per kwh x kw's x hours on for.
kwh usually around 14-15p (check with your supplier)
kw's-mines a 3kw yours should say on it somewhere.

It really is that simple. I know my day and night rates per kwh, so its a simple case of hours used times price per hour.
I dont know if there is anyway you coukd actually prove this if investigated, unless perhaps you fit a dedicated smart reader to your supply cable and to show this??

OK so if you put it on for an hour in the morning your 45 pence, but if they have a temp cut off and you put it on at night then that's not as simple to calculate.

Remember there will also be different vat rates for business and domestic use, if you are claiming a percentage for business
use then you will need to pay the extra vat on that amount.
Not just as simple as some think.

I guesstimate 50p per hour and reckon 5 hrs per night. Then I reckon 5 nights october and march. 10 nights nov and feb. 12 nights dec (Xmas) 15 nights Jan.
57 x 2.50 = £142.50
