Yes, you had to vent the kitchen heaters into a chimney Tom because they ran 24/7 during the cold months. But the smell definitely was still there in the house when they were on. Just about all of the houses in this area used to have at least a chimney in the front and one in the back for the kitchen heater. Once people got central heating, those old arks were replaced with smaller electric or gas stoves. Many also had a coil that ran around the burner that heated water for the house into a tall storage tank next to the stove.
