Hi all , 4 of my 5 tanks are heated and i was just wondering about the idea of insulating them in an effort to reduce electricity cost . They are located in such a way that the viewing panel is the front pain of glass . I was wondering about wrapping the other three sizes in some form of insulation maybe polystrien or other insulation . My question is for the small outlay cost wise would it be practical to do and would it reduce running cost , finnally what tpye of insulation would be best . As always your views and ideas are gratefully accepted

Robert, whatever you can do to effect savings is worthwhile.
However, some people would consider styrofoam (polystyrene) to be rather unsightly but if this isn't a problem for you I would suggest you should go for it.
It's worth considering that most heat is lost from the top of the tank (heat rises...) so consideration should be given to this fact.
In the past I have also draped a sheet of bubble wrap across the front of tanks overnight (when no fish-observation is happening) - I'm not certain of how much heat is saved by doing this, but in the words of the Tesco advert 'Every Little Helps'.

Maybe more members can add their observations?

I personally think the styrofoam is pretty efficient and if it won't be seen I reckon it's as good as anything I've ever tried.
Kingspan do insulation boards which are faced with sheet foil so might just be better, not sure on that one.
Either WILL save you money on electricity bills - I'm not altogether sure how much, but in this day and age any saving is worth consideration, however small.

My largest cause for concern (perhaps concern is too strong a word) is the amount of heat you must lose with only glass for top cover. Maybe you could look into this a bit further?

Turn all your heaters down a couple of degrees...Your fish will be fine...

24 degrees C is just a general average guide...Its not set in stone...I mean fish of all kinds experience different temperatures at different times of day and during different times of the year...

Most heat escapes via the top as heat rises just like John stated...So the top of the tank is what needs to be addressed more so than the sides...

The cooler your water the less evaporation also...

I would recommend getting the silver foil insulation thing, I am pretty sure it would have a noticeable effect as it did with my house, the silver foil is supposedly has more insulative properties than earth wool .

Going to have a look at the kingspan insulation after the hols next month , while i know most of the heat raises and is lost through the top of the tank, is there anyway to reduce this better than just a piece of glass
