((IRL: repainted my tub (upstairs) on Thursday, the paint was pretty fumey, turned the heat off and opened windows... about an hour and a half later, closed windows and switched my thermostat back on... same problem with my heat (second floor, my heat loop has its own valve on the steam line (boiler)). My previous fix hasn't fixed it... it's 54F right now... I'm sitting here in my jammy's and a hoodie))
