Boiler heat in Maryland
Maryland 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.
Oil-fired boilers remain common in Maryland. They need an annual nozzle, filter and combustion check, and running out of oil can pull sludge into the burner, which means a service call even after delivery.
With IECC zone 5 winters, a boiler that stops in Maryland 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.
