Mechanical Heat Recovery

The Vent-Axia through-the-wall range of heat recovery ventilation is a whole home ventilation system that supplies and extracts air continuously at a low rate with the facility to be boosted as required.

The unit is normally installed in the attic space or cupboard and rigid ducting supplies fresh filtered air to the habitable rooms and extracts stale polluted air from the ‘wet’ rooms (kitchen, bathroom). Supply and extract diffusers are fitted to the ceilings and are adjusted to balance the system.

The unit incorporates a polymer heat exchanger that tempers the incoming air before it is delivered to the habitable rooms. The efficiency of the exchanger can vary from 70% to 95%  heat recovery depending on whether it is of cross-flow or counter flow type, counter flow being the most efficient. Building Regulations are now calling for increased thermal efficiencies therefore the 95% heat exchanger is the best option.

The system can be controlled to boost speed when moisture is being generated by bathing or cooking either;
– Manually via single or multiple switches
– Automatically, typically via humidity or other sensors
These should be located in or near the wet rooms. Background ventilators in windows are not required with this system.
