For low energy and Passivhaus buildings we have got a new and innovative solution to add space heating on a room-by-room basis. The 80mm de-central water-based post-heaters can be individually controlled and thus are helping to spread the heat where you want it and when you want it. Product code for these water-to-air heat exchangers is G80 Ww.
These individual heaters are an ideal combination to our O76 90mm semi-rigid ducting (Octopus or radial system) and can be placed centrally in a plant room or just before the room outlet. They need to be operated with a pump (80 or 100l/h) and motored valves, which are controlled by room thermostats in the respective rooms.
