if you think your garage is too cold, you can always add a touch of heat
I have this sunporch that's almost as cold as the outside and I add tons of extra insulation to my brumation tanks
I have a small heater with a thermostat that kicks in when the temps sink below 45ºF
I drape space blankets over the whole thing, so I don't waste the heat
a bit makeshift, but it works really well
