I recently ordered a Sweeter Heater as I found a few recommendations here and elsewhere. The unit hasn't arrived yet, so I don't really know if things will be obvious, so I have a few questions for people that have used them. Is it like the Brinsea EcoGlow, that you want it low enough for the chicks to touch? I read somewhere that it is a bit warmer than the EcoGlow. Does it have the same fire-safe features? That the chicks could kick the bedding right against the heating surface and not start a fire? Any other advice or comments?
