The Home Efficiency Group (HEG) prides itself on superior products and services. The HEG Air Transfer Kits consists of:

• R1 Insulated Flexible Ducting (insulated with polyester insulation, not glass fibres)
• Inline Air Pump (either an axial or centrifugal positive-pressure fan)
• Variable Speed Controller/Switch
• Circular Inlet and outlet diffusers
• Ducting Branches
• Hanging Strap (can be tied or stapled to ceiling trusses)
• Duct Tape

Home Efficiency Group does not take any responsibility for the installation of these kits, or damage caused arising from its use or installation, or warrant its suitability for any purpose whatsoever. We recommend using a licensed tradesperson to install, as well as turning off the mains power to the house during the installation process. Please take a common-sense approach to installation, and do not rely on this approximate guide for installation.

To be suitable for a ducted air transfer system, your house needs to:

• have access to the ceiling cavity via a manhole;
• have a ceiling cavity  tall enough to allow a grown man to be able to move & manoeuvre. For instance, a skillion or 100% coverage cathedral ceiling is not suitable.
• have adequate ceiling insulation to retain the heat in the "destination" rooms
• Have a strong enough heater, such as a wood heater, 8+ KW Heat Pump or good electric heater
