Heat loss from houses

Reducing the need for energy

• Loft or roof insulation• Cavity wall insulation• Solid wall insulation• Floor insulation• Draught proofing• Double or secondary

glazing• Pipe and water cylinder

insulation• Energy saving light bulbs

Changing behaviour

• Turn the thermostat down

• Programme heating systems

• Close curtains at night• Only turn on lights

when needed• Only boil water needed• Shower instead of bath

Renewable Energy

• Space and water heating– Biomass– Solar water heating– Heat pumps

• Electricity generation– Wind– Hydroelectricity– Solar electricity

Biomass• Fuel: wood pellets;

wood chips; and logs• Installed costs

– £3000 for stove– £5,000-10,000 for boiler

system• Running costs for fuel• Storage space needed• Planning permission/

permit to burn wood• Carbon neutral

Solar water heating• Established technology

– Flat plate or evacuated tube

• Installed cost £3,000-£4,500

• Can supply half water heating requirements

• 2-5 sq.m of roof space• South-facing, un-

shadowed roof• Planning permission

Heat pumps• Air source• Ground source

– Borehole or trench• 6-10kW domestic system • Installed cost £7,000-

£12,000• Running costs• Works best with

underfloor distribution• Electricity needed to run

pump

Microwind turbines• Household size 1-6kW, • ~2.5kW sufficient for

average household yearly needs

• Costs £11,000-13,000 for full system

• Local annual average windspeed of 6m/s

• Planning permission• Back-up supply needed

Hydroelectricity• Close to a water source

and grid connection• Low head system costs

~£4,000/kW installed• Larger, community

systems can reduce costs• Seasonal water flow• Contact LA, EA and

Countryside Commission
