CLV buitenopstelling

Collective system in outdoor installation for closed heaters

The Opsinox CLV fireplace is designed for houses and apartment buildings where several closed heating appliances are connected to a common duct. If there is no technical duct in the building or if the building does not offer enough space for a CLV chimney, an outdoor CLV system can be installed. The concentric system provides the boilers with a combined air supply (via outer pipe, stainless steel AISI304) and exhaust (via inner pipe, stainless steel AISI316L) from the inside of the building. Both ducts end up in the same pressure zone.

The complete combustion circuit is isolated from the living spaces, no air is extracted from the house for combustion. This excludes the backflow of burned gases into the house. The combustion appliance can therefore also be placed in an enclosed space.

In practice, up to 20 boilers can be connected, with a maximum of 2 per floor and with capacities between 20 and 40 kW. The connections for the boilers are standard concentric 80/125 or parallel 80/80, other dimensions can be obtained on request. The system is suitable for both gas and oil heating appliances of the condensing type C4.2 or C4.3.
