Modern heating systems are much less susceptible to air ingress. They come standard with automatic air vents, microbubble separators, pressure sensors, and expansion vessels. Additionally, today’s HVAC piping is diffusion-tight. As a result, the air vent on the heat exchanger is only needed during initial startup or in exceptional cases.

In the latest Jaga units – such as those in the Net Zero range and our Briza models – the air vent is only accessible after removing the casing. Due to advancements in installation technology, the extended air vent, which was previously used to allow access without disassembling Low-H₂O wall units, has become redundant.

To reduce the ecological footprint, Jaga will no longer supply the extended air vent as standard with Low-H₂O wall units. Instead, these units will be equipped with the angled air vent.

The extended air vent will still be available as a separate item and as an optional accessory, but at an additional cost.
