Discrete Whole House Heat Recovery
The Vent-Axia Lo-Carbon Calido is designed to remove stale air from any habitable room and replace it with fresh air. This unit is designed to be ducted therefore it can benefit more than one room at a time i.e. if installed in a bathroom, stale and moist air will be extracted and fresh air will be supplied to other habitable rooms via installed ducting.
The Vent-Axia Lo-Carbon Calido offers up to 80% heat recovery which helps reduce the amount of heat lost from the property. This helps save money by reducing energy costs as well as reducing carbon emissions. The unit cleverly recovers heat from heat lost through extraction and reuses it to warm the air re-entering the property.
One unit can help improve the air quality of a whole house and with changeable filters it can help provide clean air all year round. With three air flow options available, the Vent-Axia Lo-Carbon Calido can be installed in many types of properties and its compact design means it will ventilate and recover heat quietly in the background. It can also be wall or ceiling mounted depending on space availability, making it perfect for many retrofit applications.
The Vent-Axia Lo-Carbon Calido is a robust unit with an IP24 rating and is double insulated for extra protection. It uses an EC motor, which is incredibly reliable and comes with a five year warranty.
Typical Installation
The Vent-Axia Lo-Carbon Calido requires two 100mm diameter holes - one to extract stale air and one to intake fresh air. It also comes with a drilling template for an easy install.
