STXman;4059018; said:there is a device that you can use and what you do is that you put the heater inside of this sump kind of thing and i think its called life guard fire guard idk but you put ur heater in the sump and as the water is going through the sump it is heated with saves money and it heats it up quicker. also for the summer you should get a good temp reader. if it gets to hot put ice in the sump and shut off the heater. i heard about this from my local fish store and the owner is an expert. hope this works out for you.
most heaters should shbut off if the water gets too hot.....
