H-line is a horizontal heat recovery ventilation system that is installed through an exterior wall. This means that roof space is not required for ventilation making H-line perfect for apartments, townhouses, sleepouts and anywhere that roof space is limited.
H-line features an EC motor with a ceramic core; this qualifies H-line as continuous extract or balanced ventilation depending on the setting chosen. On medium air flow H-line achieves the required air changes for a 27m² space at 2.4m stud height. One to two H-lines can provide the balanced ventilation required for most living rooms while only one is typically needed for bedrooms.
The first H-line systems are being installed in the next few weeks (as of 20/05/22).
When correctly specified, H-line meets NZBC G4 fresh air compliance, where outdoor air supply at a rate of 0.35ACH (air changes per hour) is required if 5% openable window area is unachievable. H-line also meets Homestar v5 for residences targeting 6 or 7 stars, which must now have continuous extract ventilation with higher efficiency EC fans as a mandatory minimum.
