Heater Questions

I have 2 tanks I am buying new heaters for. So one is a 25 tall and the other a 36 bow. Our house fluctuates from 69-74 usually and occasionally drops to 63-65 on really cold nights. What wattage do I need?
Also what brand is safest? I was looking at ehiem jager but if there is a better safer option Im all ears. Thanks and God bless!

I use the Jager Thermostat Heater 100 watt on my 29 gallon high and it keeps the temp at whatever I set it for. My home temps run as low as 60 to as high as
90's. I have let it get colder and the tank temp stays good. I like the fact you can calibrate it if the temp seems off. You just turn the dial to the actual tank temp that is showing on a good thermometer and then set the temp you want. I have only had to do that once in the year I have owned it. I have moved it around a lot, forgot to turn it off a few times when changing water, and even dropped it and it is still working.

A 100 watt should be enough to heat both the 25 and the 36 gallon. I went by the chart listed with the heater here Aquarium Heaters: Eheim Jager Thermostat Heater at Drs. Foster and Smith. I was lucky enough to get it on sale at that site for a lot less than what they are listed for now. You might be able to find it cheaper at Amazon.

Cool thanks! I will be buying off amazon! I am paranoid that my heater will break and kill my fish...

Hello G...

4 watts per gallon of tank volume is sufficient and "Theo" has a very good product.

Thanks! So does anybody take any special precautions against overheating in case of accident?

Most if not all heaters will turn off once they reach the required temperature and turn back on when it drops. So not really, too much direct sunlight? I dont know

In that case.. no, i cant think of any precautions you could take if the heater malfunctions... a temperature alarm? If there is such a thing. Check them daily, i cant think of anything tbh my minds blank on this one.

Your best defense is probably researching for and purchasing a quality product. Even then, there's no guarantee (like most of life).
I have heard of some folks that get two lower wattage heaters ( ie two 50 watts) instead of one. This way, if one fails it takes longer to become a real problem. Also, with a heater at both ends of the tank you get a more even distribution.
