  2. 2. Methods of Heating Central heating: heat created by burning fuel (solid, oil, gas) in a boiler in a central location and delivered to the rest of the house by heating and circulating hot water through radiators . House kept @ 16-20 C.⁰ Hot water provided as well. Partial or background heating: electric storage heaters using off-peak electricity provide gentle background heat but some rooms e.g. living room, will need another heat source Individual heaters: each room has its own source of heat e.g. Open fire, stove, portable gas heater, electric fan heater, oil filled radiator.

Heating methods Advantages Disadvantages Quick Efficient i.e. no waste Clean Easy to use Pleasant No storage needed Heats water No fumes or ashes Easy to regulate Portable Cheaper to run Modern features e.g. timer Dries the air No hot water Dangerous Storage needed Gives off fumes Not cosy Lots of work Dirty Not portable Causes pollution Not easy to control
  5. 5. Insulation Heat is lost from a house through walls, roof, windows, doors and floors. Good insulation can stop 75% of this heat loss. Insulation is made from materials that are bad conductors of heat e.g. still air, wool, polystyrene.
