The central-heating system is particularly for greenhouses, having a heat source and a set of pipes with radiators, together with regulators for the heat emitted. One or more of the radiators are designed to emit heat by both radiation and convection. They can comprise a horizontal steam pipe with reflectors forming the radiation portion, while the convection portion comprises condensate drain pipes connected to the lowest part of the steam pipe, and each with a condensate vessel. These pipes can be connected to the expansion bends in the steam pipe. |
