沈阳散热器认为在供暖系统中，把热量从热源输送到散热设备的物质称为热媒。在的供暖系统中，可把热水、蒸汽、热空气、烟气等作为热媒。
1.热水供暖系统，它是以热水作为供暖系统的热媒。一般认为，凡是温度低于100℃的水称为低温水，高于100℃的水称为高温水。低温水供暖系统供回水的设计温度通常为70-95％℃；高温水供暖系统的给水温度，我国目前一般为130—150℃，回水多为70℃。由于低温水供暖系统卫生条件较好，目前被广泛用于民用建筑中。
2.蒸汽供暖系统，它是以饱和蒸汽作为供暖系统的热媒，按蒸汽的压力不同，可分为低压蒸汽供暖系统(蒸汽压力小于或等于70 kPa)、高压蒸汽供暖系统(蒸汽压力大于70 kPa)和真空蒸汽供暖系统(蒸汽压力低于大气压力)。
3.热风供暖系统，它是以热空气作为供暖系统的热媒，即把空气加热到适当的温度(一般为35—50℃)直接送入房间，用以满足供暖要求。
4.烟气供暖系统，它是直接利用燃料在燃烧时所产生的高温烟气在流动过程中向房间散出热量，以满足供暖要求。烟气供暖虽然简便且实用，但由于大多属于在简易的燃烧设备中就地燃烧燃料，不能合理地使用燃料，燃烧不充分，热损失大，热效率低，燃料消耗多，而且温度高，卫生条件不够好，火灾的危险性大。
