Can I Submerse My Heater Fully?

[Deleted member 107737]

Hi All,
 
Can someone have a look at my photos regarding my heater and tell me can i fully submerse it??
 
it has a red line on the back saying  (   \/ Minimum water level  \/    )
 
 
I dont want to fly accross the room so thought i would check in advance.
 
Also how much ££££££ would it cost to run one per month at the lower tropical fish temp.
 
My current room temp is between 22-23 C all day/night.
 
 heater aquarium please give me a rough cost so i can decide for myself if its worth it or just get a load of minnows
 
ive got 150 litre tank and 200w heater.
 
Thanks,
 
Dave


Sorry i meant my tank temp is 22-23 C during the day and night.

I would put that heater 100% underwater it will be fine. 
 
As for using it, I doubt it would be anymore than running a few house lights.

ok thanks for your help.
 
Im still in the debating stages of wether to have a heater (costs involved). If say its £5 a month then no problem I can afford that but if the bill is going to be say £20 a month then i will stick with cold water unheated fish.


If you look at my tank, the thermometer has for the last 2 weeks been saying 22/23 C every time i look at it between 6am - 11pm. just wondering how much cost to say just heat to minimum tropical fish territory???

I would HIGHLY doubt a heater would give you a 20quid bill. 
 
I suggest just putting it in and see how it goes, Far more benefits having a heater in than without.

well i think as you have been very helpful, i will give heating it a go for say a month. might be OCD territory but i will monitor the electricity meter outside say over 1 day period.
 
should get a rough estimate from that

I honestly think you expect the heater to be on 24/7. But once it hits the desired temp it's rarely on after that unless you're room temp is something like 7c.
 
My computer is on almost 24/7 with a 900watt supply and its not even 20 quid bill so yea

Agreed; i said in your other thread (in case you haven't looked there yet) that heating a 100l tank will cost you no more than a pound or two a week.

hi sorry, i started 2 seperate threads but somehow they have merged into the same subject

 

[fluttermoth]

lol, it's ok

thanks for your help, going to stick to the other thread only from now on.
 
kind regards,

We got a free indoor electricity monitor from our supplier (Southern Electric).  It just plugs into a socket and tells us how many watts we're using around the house, I can see it going up and down when my heater switches on and off. 
 
Might be worth checking with your supplier to see if you can get one free too.

thats helpful most definately

200W for 24 hours a day, and 30 days in a month...  That works out to 144,000 W*hours of energy.  That's 144 kW*hr.  
 
 
So, that's the amount of energy you would pay for using each month.  As I understand it, the price for energy use in the UK is different day vs. night.  Some rough estimations is this:  10p per kWhr during the day, and 5p per kWhr during the night, means that you would be paying 7.5p per kWhr...  It will probably be lower than that as the heater would be needed more during the night, rather than the day, as temps drops overnight.  (So, for ease of calculations, let's say about 6p is a more realistic number.)
 
 
In the winter, when the heater will need to work the hardest, it will run at most 25% of the time - unless your house loses heat itself.
So, rather than 144kWhr in the winter, it will be closer to 36 kWhr (at most), which would cost: 2.16 pounds in winter.
 
In the spring/autumn, it should work about half the amount in the winter at most, so that means about 1.08 pounds in spring/autumn.
 
And in the summer, it shouldn't have to work almost at all, but let's be generous and offer it at 1/2 of the spring/autumn amount. 0.54 pounds.
 
 
So, ANNUALLY, you can expect to spend roughly 14.58 pounds, or averaged over a year, roughly 1.215 pounds per month.

Electricity prices in the UK keep going up and up, unfortunately, so this is a valid concern.
 
It's easy to find out tariffs of your local electricity supplier.  Mine charges 13.42 pence per kW/h (day or night, no difference).
 
I've got a 50W heater but my electricity monitor tells me that it is consuming 100W (which I don't quite understand!)
So assuming that's on for 8 hours each day (I suspect it isn't really on that long), that's 100x8x30 = 24kW/h per month.  Which works out about £3.20 a month, for me.
 
We have to consider that we keep getting massive price hikes year on year, so it's only going to rise.

Well, that price quote I found was from yahoo answers - and I just checked it - it was from 2008!  lol

Sorry, my prices were way out of date.

That's 24kW*hr.    The science guy in me just couldn't let that go.  
 
 
The one thing about the cost is that it will cost more in the winter than in the summer...  Also, you can give the fish a bit of a "seasonal" change and allow the heater to sit a couple degrees lower in the winter than other times of the year.  While tropical fish don't have wide temperature variants in their habitat, they do get mountain snow runoff, and rainy seasons, which will vary the temps and that's why it is an effective way to induce spawning when doing a water change with cooler water, especially when paired with a drop in the Barometric pressure.
