LIHIC Right Ans - Low Income High Costs Indicator
A household is considered fuel poor when? Right Ans - If they have above
average fuel costs and they need to spend more than 10% of household
income to achieve a satisfactory heating regime.
Safe/ average house temperature? Right Ans - 21 degrees in living room

Ans - 15
Percentage of average household cooking energy use Right Ans - 2.5
Radiant heat Right Ans - Travels in straight lines e.g. how sunlight travels
Convection heat Right Ans - applicable to air and water, where heat moves
from a warm spot to a colder spot, heated molecules become lighter and rise,
displacing cooler and heavier particles which fall.
,Conduction Heat Right Ans - movement of heat through a material, relevant
to the choice of materials used in housing construction
Electric Fan Heater controls Right Ans - on/off, Thermostat, fan speed, heat
setting
Electric convector heater controls Right Ans - on/off, thermostat, timer
electric storage heater controls Right Ans - input/charge, output/boost,
on/off. timer
Fan assisted storage heater/quantum storage heater Right Ans - on/off,
thermostat, heat settings, timer
electric radiant fire/ bar fire Right Ans - on/off, thermostat, heat settings,
timer
electric infra-red heater/ halogen heater Right Ans - on/off, thermostat,
heat settings, timer
electric oil filled radiator Right Ans - on/off, thermostat, heat settings,
timer
Open fronted gas radiant/ convector fire (gas fired could have back boiler
behind) Right Ans - Ignition, temp setting, boiler thermostat if there is a
back boiler
Gas decorative effect fire, open and close fronted Right Ans - Ignition, temp
setting
Gas convector heater/ wall heaters (room sealed) Right Ans - Ignition,
temp setting
Closed solid room heater Right Ans - Damper to control air flow, boiler
thermostat if there is a back boiler
Bottle gas heater (portable, liquid petroleum gas LPG) Right Ans - ignition,
temp setting
, 4 main safety issues when using a fuel burning appliance Right Ans - -
Carbon monoxide poisoning and fires
- Fit a smoke alarm, test every month and replace after 10 years
- Never leave candles, cigarettes unattended
- Ensure there is good ventilation
How often are landlords required to carry out a safety check with a Gas Safe
registered engineer? Right Ans - Every 12 months
Warm air heating system Right Ans - - distributes warm air around the
home
- Air is heated by a central unit using gas, oil or electricity
- Distributed using ducts and a fan to drive out the warm air into rooms.
- Heat is emitted via grilles on the floor or at the bottom of the walls
- Thermostat and timing controls
Wet central heating systems Right Ans - - Hot water is circulated around
the home via radiators and pipes.
- Source of hot water is the boiler which heats up water using fuels such as
natural gas, oil, LPG or solid fuel
- Gives out heat via convection
Conventional boiler/system boiler Right Ans - Hot water in cylinder is
heated indirectly via a heat exchanger within the cylinder. Can be fuelled by
natural gas, LPG or oil. Can be condensing or non-condensing. Hot water
stored in the cylinder.
Combination boiler Right Ans - Extra heat exchanger within the boiler
allows it to heat up water quicker. Householders only pay for the hot water
they use. Produce hot water for both space and water heating systems. Fuelled
by natural gas, LPG or oil. Can be condensing or non-condensing. Doesn't need
a hot water cylinder.
Soild fuel room heater with back boiler Right Ans - Situated in fireplace in
order to use existing flue. Hot water is heated by burning solid fuel in the
grate. Type of conventional boiler. 4 main types: open fire with back boiler,
closed room heater with back boiler, free standing manually fed boiler, free
standing automatically fed boiler.
