I have a Circa-1905 Arts & Crafts bungalow which has an original coal-burning fireplace in the living room. The fireplace is a Cahill coal-burning fireplace. Does anyone have any information on this fireplace insert? I'd like to restore the fireplace, but don't want to use it because the house has a new central HVAC/gas pac unit. The house also has two new electric fireplace inserts with holographic flames and also a vented gas log fireplace, but I'm mainly interested in the coal fireplace.
