WELCOME TO AMBIENCE

Ambience Harmony Heat Recovery offers optional add ons to complement your standard Ambience Harmony Heat Recovery system, to achieve the best outcomes for your home.

Roof Cavity Exhausting

The Roof Cavity Exhausting includes a switching mechanism that allows the system to exhaust the warm air into the heat exchange unit and recover that heat within the roof cavity when it is available. This heat is only available during the daytime when the sun is shining. This operation is worthwhile particularly in homes that have a dark coloured steel roof where the heat gain can be substantial, even in winter. At night, this heat source is not available and the exhaust air can be switched back to be sourced only from within the warmer parts of the home.

This system will work automatically if installed. It will read the temperature in the roof space and open a damper to allow the warm air from the roof cavity into the heat exchanger. This air is filtered to protect the fan. The air doesn’t enter the supply to the home, only the energy that is recovered will be transferred to the air supply that enters the home.

Summer Bypass

The Summer Bypass includes a damper assembly which allows the supply of fresh outside air directly into the home, without going through the heat exchange system. Heat will not be recovered from the warmer inside air of the home so no further heat will be picked up through the heat exchange process. When the Summer/Winter switch is turned to Winter, the air is directed to run through the heat exchanger again.
