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
Solar electricity• Photovoltaic (PV) cells• Typical domestic system:
2.5kWp, 10-20 sq.m• ~£10-18,000 installed cost• South facing, strong, un-
shadowed roof• Roof pitch 30-45 degrees• Planning permission
