Cost of keeping reptiles

[iann41]

I’ve just done a few calculations concerning the power usage and the heating of reptile enclosures.

I have two aquarium tanks which share a 21w heat mat. It covers 1/3 of each tank. The mat is set to 30°C.

Over 5 days (120hours), it used exactly 1kwh. Over the year it will then consume 73kwh.

If we say that electricity prices are roughly 18p a kwh, then I recon that over the year, keeping reptiles will cost £13.50 give or take a few pence.

I don’t have a light over the tanks, but if you do then calculate like this.

Wattage of bulb (in kw i.e 40w=0.040kw) X hours of usage. This figure is then times by 0.18, the average price of kwh electricity.

Work out the daily usage then times by 365 for yearly usage first.

An example of 40w bulb on for 12hours a day over a year,

40w X 12 hours = 480 = 0.48kwh
0.48 X 365 = 175.2kwh
£0.18 X 175.2 = £31.54 a year for the bulb to be on 12hours a day.

Hope this is of some use,

Please pull me up if any of this is wrong.

Hi,

Very useful! 18p is very high tho! our is 10.48p p/kw and it goes even lower than that after we use a certain amount!

omg i wouldnt dare add my cost up the electric alone is stupid .................and thats before i have to buy a cabbage

wow cheers for that mate!

now trying to work out how much my other halfs xbox 360 costs to run, as i know for a fact the reps dont cost half as much as that thing does when hes on it constant! had many rows now i can say it only cost me 7.80 a year to run my lot! (thats including my new reps coming sat! 3 big enclosures too!)

think i did it wrong though (edit)

If you're on 18p I would say change suppliers, I just have and got mine as low as 9p/kw, it was 14p before which I thought pretty high. Worth looking around as when you add it up with tvs and computers and washing machines etc. you can save a fair bit a year.

My elecy currently costs around £5/6 a day

which works out to: £2190 a year...

There i did it... I worked it out...

& around £2000 a year for food... Cant work this one out accurately as i get differrent bits in all the time for the monitors and dont make a note of how much it costs...

All heat sources should be controlled by a thermostat and this can mean that the full wattage of a heater is not being used, so it is difficult to calculate power consumption.
The only way is to get an energy consumption measuring unit such as the Brennenstuhl PM230.

All my bulbs are on dimmers though, so I have no idea what wattage they're pulling.

I have a power meter and had it running for the full 120hours and consumption was 1kwh. This was with a 21w heatmat and thermostat set at 30°C.

I assumed that £0.18 was an average price for electricity but as others have said, it's not.

I know there are differant tariffs, mine is for quartly bills, no standing charge, 'pay what you use' sort of thing. It's with Southern Electric and is 17.8p kwh.

Could we post who our suppliers are, how much we pay and which tariff?

Think this could be interesting.

This thread got me thinking so have ordered one of them wattage meters that shows how much you are using. Be interesting to see how much my rep room uses, not sure i want to know. But I imagine its not as bad as someone who keeps large reptiles. I will post the results when it shows up.
