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 @ 16-20⁰C.
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.

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.
