We used to have a guy in this area who would very specifically call out and require a specific reason for anything other than an ordinary temperature head.
It got me thinking, and now I just use standard everywhere. I mean if you really think about it, something would have to be incredibly wrong for a dwelling unit laundry room to get over 100° at the ceiling. This is abnormal. An outside closet with a hot water heater maybe I could see in certain areas of the country, but I've been putting 155s in them for a while now. For non-residential heads, 175s are a PITA to get sometimes as well. They never seem to be in stock when you need them. I just go to 200s for those and call it a day.
