Coal-fired bathroom water heater

Description

The low-pressure boiler seen above is used for heating household water by burning solid fuels, e.g., wood, hard coal or brown coal. The upper part of the boiler consists of an enclosed vessel made of copper sheets operating on the overflow principle, and an internal pipe for discharging hot gases from the burner at the bottom of the boiler. This invention significantly improved the standards of household hygiene by providing access to domestic hot water. It was very widely used in residential buildings from the mid-19th century, i.e. from the time when the modern water supply system was invented, up until the 1960s. Operation of the boiler required the user to abide by basic safety principles as there was a very high risk of carbon monoxide poisoning. The next stage in the development of the device was the gas fired boiler, which was patented in 1894. Manufacturer: Unknown producer, early 20th century Inv.
