tank temp with out a heater

Personally, If you don't have a climate controlled house removing a heater may not be wise.

The basement may be a better place and have much smaller temp swings, but it can also get much cooler, then would require a heater and also maybe a chiller if your house gets hotter in the summer months.

I guess for most it will depend on the temp swings during the day/night, also during the changing seasons.
