- Continuing the conversation with Cameron Grant from Fresh Ventilation, before welcoming co-director Claire Grant — the founder of the business.
- Heat recovery ventilation (HRV) is booming, but many homeowners are paying more for an ERV assuming it's better. A Fantech study in Sydney found an HRV outperformed an ERV for 50 out of 52 weeks of the year — for most of Greater Sydney and south of Newcastle, HRV is the right choice.
- The DVS Reclaim offers a more affordable retrofit heat recovery option designed to work outside the thermal envelope — and Cameron saw window condensation disappear overnight in one particularly problematic home.
- Unflued gas heating produces water vapour and carbon monoxide — ventilation can help manage the symptoms but Cameron's advice is clear: avoid it if you have any other option.
- Basement rooms and spaces that back onto a subfloor will always struggle with damp unless ventilation is designed in from the start — Claire explains why extraction along the shared wall is key.
- Common air leakage points in your home include timber floorboard gaps, behind power points, old downlights cut straight through the ceiling, and anywhere plumbing or electrical enters the building — sealing these up can make a significant difference to energy performance. Cameron is a certified blower door tester through ATTMA.
- The Fresh Ventilation warehouse was designed by Andy Marlow from Envirotecture and built to Passive House standards — it needs just a 7kW system to condition double the floor area of their previous warehouse, which ran an 18kW system constantly.
