:OT: No offence but I went there for a holiday and you are right the weather was crap all the time. People were nice though.!!!!

Heaters with thermostats should keep the temperature at the specified range. With cheaper thermostats for example,it might say 80 degrees on the dial but in actual fact it is heating the water to a constant 86 degrees(expensive ones can be wrong to). That is why it is wise to keep an accurate thermometer, to monitor the water temp. Never rely on the thermostat dial. Some cheaper heaters have a built in thermostat which is set to a certain temperature and cant be changed. Also I dont know if many people know this but some thermostats waste energy. Let me explain, if the voltage in your house is 110V sometimes the voltage at where you plug the heater into the thermostat can be only half that 55V. So in effect you are really only geting half the output of the heater.

I have done electrical work, and if you have anyplace in your home that has a voltage that low then there NEEDS to be some work done. Asking for trouble in a lot of ways.

Noticed the same problem with my 10g. I have started turning the lights off during the day when not at home, and the house is at it's hottest. Not an option for planted tanks (unless you left the lights on late into the night.)

Also for major overheating check out the DIY section for "chillers"

The good thing is that Flourescent light give off minimal heat, the incandescents give off a lot of heat. Most of the plant sustaining lights I have seen have been the flourescent.

The thermostat is what is causing the voltage reduction, how do I know this my brother is an electrition and we measured thermostat to see what voltage it was puting out and it was approximately half the voltage.This tends to be a problem when you have 15*500w heaters in your tank.

I see, you are talking about a single thermostat with multiple heaters correct? I was thinking of the single all inclusive units. Now if that is correct, do you have a system like a thermostat that is used with heaters designed for that thermostat (kind of like a kit)?
 
I ended up getting a industrial thermostat so as the voltage would not drop with multiple heaters. I dont quite understand what you mean by a kit?
