You will need additional items to install your Solar Heat Harvester System, these include:

For both Attic and Conservatory Solar Heat Harvester Systems
a) A 5 amp fused switched unit to match your existing switches, and a back box - from Screwfix

b) Two lengths of twin and earth mains cable to connect mains supply to the switch unit and to the Attic Heat Harvester Controller - from Screwfix

c) sundry screws

For Conservatory Solar Heat Harvester Systems only
d) Two lengths of PVC pipe, to stop hot and cold air escaping into the wall, of a diameter that suits the fan unit you will use

e) Two gravity air vents, one stops warm home air escaping into the cold conservatory, one stops cold conservatory air entering your home

For Attic Solar Heat Harvester Systems only
f) Aluminium foil insulated flexible ducting of required length - this can be obtained from ebay

g) Two jubilee (hoze) clamps to clamp the insulated ducting to the fan and air valve - can be obtained from ebay

h) Something to support flexible ducting in the attic, e.g. pieces of wood to be attached to the rafters that have loops of webbing fitted to them that pass underneath the ducting and where needed strips of wood to keep the ducting fairly straight - see photo gallery.

i) A ceiling air vent of a suitable size that suits your home decor

j) If the room receiving heated air is relatively air tight you may need wall mounted gravity air vents that let the heated air flow through your home
