They used a type of warm air heating system known as hypocaust but after the fall of the roman empire people forgot about furnaces for about 1 000 years and used fireplaces instead it was during the 13th century when cisterian monks began using furnaces again to warm their monasteries.
Different types of furnaces for burning coal fuel oil and gas.
Fuels that burn like coal natural gas oil and wood have heat loss out of the chimney.
Per 100 million btu.
That heat loss is accounted for using the efficiency column.
Summary efficiency of fossil fuels.
Mains gas is the most popular heating fuel in the uk for the following reasons.
Fossil fuels tend not to keep as much of their original energy input as renewables.
1 by other means such as heat pumps or solar heating.
Furnaces have a long history of heating homes which dates back to the roman period circa 1200 b c.
In this section we ll be shedding a light on the different types of furnaces based on the type of fuel utilized for heat generation.
Natural gas furnaces furnaces that use natural gas as their source of fuel are commonly used in most households as they re relatively inexpensive and easy to maintain.
Consult the manufacturer s documentation to find out what the efficiency of your particular heating unit is.
It s competitively priced so it s usually the cheapest option it s the cleanest of the fossil fuels for each unit or energy of heat its co2 emissions are half those of oil fired central heating and a third of those from coal.
