Ducted Air Circulation

Air Comfort & Control

Thousands of homes are enjoying the benefits of HEG Air Circulation Systems. The base system distributes air to up to 10 rooms, whilst various modules offer enhanced functionality like window condensation control & roof heat recovery. These systems are between 1/6 and 1/2 the cost of ducted heat pumps, and interoperate with wood, gas, or electric heaters, and have a summer mode also.

Ceiling Insulation

Warm in winter, cool in summer

Ceiling insulation substantially increases the temperature of your home in winter, cools it in summer, and reduces window condensation. It is always the highest thermal priority in any home.

That's a HEG of a lot warmer!

Stop the cold beneath your home from lowering the temperature of the floor. Underfloor insulation typically leads to a 3.5 degree increase in night time temperatures, and also tends to draught-proof suspended floors.

A little bit about us...

Kane, lead quoter and installation supervisorWe're a local Tasmanian company that provides professional installation of a range of related "home efficiency" services, such as insulation, heat pumps and HEG Air Circulation Systems. With bases in Hobart and Launceston, and regularly servicing the NW Coast and regional areas all over Tasmania, we have the entire state covered, as well as selling DIY Heat Transfer Kits nationally. 

We provide free onsite quotes, but we don't need to come onsite to provide fixed-price quotations. Ducting systems are fixed prices based on a per-outlet basis. Ceiling and underfloor insulation is charged on a per-SQM basis, which means we can estimate based on Google Earth measurements to within 5% accuracy, then do an accurate measure-up on the day to adjust a final invoice. Please call a Home Efficiency Group (HEG) sales consultant on 1300 96 80 60 to arrange an obligation-free quotation.

HEG Air Circulation System

Spread payments over 18 months... Limited Time.

Sign up now & spread payments over 1 to 5 years, from a minimum of $1000

  • Duct cool air in summer

  • Avoid the winter rush/delays

  • Start saving money sooner

  • Improve the health of your home

Install a Ducted Air Circulation System using a Community First Green Loan so that you can avoid the winter rush for installations (usually 4 to 8 week delays)! You can use the system to duct cool air throughout your home during the warmer months. This feature is designed to flush hot air out from bedrooms or away from overly sunny living rooms, greatly improving comfort levels. By installing a system now, you can also reap the benefits of the "Roof Heat Recovery Module" during the next Autumn, thus saving you money earlier than if you waited until Winter to install. 

Summer Roof Ventilation

Your roof gets hot in summer, which in turns puts an enormous heat load on your living areas. Extract the heat from your roof space before it comes an issue using a roof ventilator such the solar-powered Solar Whiz or a powered version such as CSR Edmonds Airomatic.
