Boiler heat in Illinois
Illinois has a large stock of older homes and multi-family buildings with steam and hot-water boilers, many with cast-iron radiators that are decades old. Air vents, sight glasses, low-water cutoffs and pipe pitch problems are the everyday boiler calls here.
With IECC zone 5 winters, a boiler that stops in Illinois also puts its own piping at risk. Baseboard loops along exterior walls can freeze and split. Glycol protection is worth asking about for vacation homes and zones over unheated spaces.
Polar vortex events have pushed Chicago-area wind chills far below zero, the kind of cold that exposes weak furnaces.
