So, some heat plates have 2 settings, a low & a high. I think the high is too high/hot for brooding - but would be fine for heat as a wall mount. I have (had) 2 brooder plates. One is only for brooding. The other can be used with the legs for brooding, or without and mounted vertically to a wall. That one does get too hot on high imo for brooding. It also depends on how high I have it adjusted relative to the chick's height, and how hot/cold it is when using it. I brood my chicks in the 'mudroom'. an unheated space with the louvered 'breezeway' type windows...so I have, when the chicks were first starting out, had the low wattage one set correct height for them, and the other set as high as it would go on the hot setting to give them extra 'warm space' and so that it also wasn't cold around the edges of the other heat plate. It worked really well. Then, as they grew and the temp outside moderated a bit, I switched to just that one but on low. (that one was bigger than the other, and as they got bigger, the other wasn't large enough).
Sorry, I don't remember the brand, and it has since died, so I can't check as it has gone the way of the wind.
