Gas Fires. The gas radiator is used extensively for individual room warming, especially where short-term heat is needed. Most of the heat produced by these radiators is available to occupants via radiation, with minimal heat loss up flues compared to coal fires. Portable gas fires without flues are discouraged due to potential carbon monoxide poisoning and unhealthy air conditions.
<Callout type="warning" title="Danger: Carbon Monoxide Poisoning">Portable gas fires without proper ventilation can release dangerous levels of CO into the room, posing a serious health risk.</Callout>
Gas-fired Water and Steam Radiators are also in use but should only be used with excellent ventilation due to lack of flues. Gas fires are ideal for rooms where constant heat isn't required, such as bedrooms.
Calor Gas is recommended for rural areas without piped coal gas supply. It has a higher calorific value than coal gas and can be supplied in cylinders under pressure. Proper installation and handling of Calor Gas cylinders indoors is crucial to avoid hazards.
Electricity offers the most sanitary heating method, with all heat available for warming air and occupants. However, it's expensive except for occasional use. Radiant electric heaters provide immediate warmth but are less efficient than convection heaters in large spaces.

Oil thermal storage plants can be used to store heat generated during off-peak electricity hours, providing an economical solution in large buildings.

Modern Application
While many heating technologies have evolved, understanding early methods like Calor Gas and electric radiant heaters provides valuable insights into energy efficiency and safety. Modern readers can apply principles of efficient heat distribution and the importance of proper ventilation to contemporary survival scenarios.
Frequently Asked Questions
Q: What are the risks associated with portable gas fires?
Portable gas fires without flues release all combustion by-products into the room, leading to unhealthy conditions and potentially dangerous levels of carbon monoxide.
Q: How does Calor Gas compare to coal gas in terms of efficiency?
Calor Gas has a much higher calorific value than coal gas (about 3200 B.Th.U. per cu. foot compared to usually about 500 B.Th.U.), making it more efficient for heating purposes.
Q: What is the advantage of using electric heaters over other methods?
Electric heaters provide complete control via thermostats and switches, allowing precise temperature regulation and immediate heat availability when needed.
