AGA Rhapsody early models are versatile heating appliances designed to provide warmth and hot water using various fuels, including gas coke, anthracite, and manufactured fuels. They feature a gas ignition burner for easy lighting, a thermostat for regulating the burning rate, and a riddling lever for ash removal. These stoves are efficient in heating water, with the supply increasing when the thermostat is set higher.
