地热辐射采暖，简称地暖，是将温度不高于60摄氏度的热水或发热电缆，暗埋在地热地板下的盘管系统内加热整个地面，通过地面均匀地向室内辐射散热的一种采暖方式。地热辐射采暖与传统采暖方式相比，具有舒适、节能和环保等诸多特点。在国外这项技术不仅大量应用于民用住宅和医院、商场、写字楼、健身房和游泳馆等各类公共建筑，还大量应用于花坛、厂房、足球场、飞机库和蔬菜大棚等建筑系统的保温，甚至应用于室外道路、屋顶、楼梯、机场跑道和各类工业管线的保温。
Geothermal radiation heating, referred to as geothermal heating, is a heating method that heat the whole ground in coil system buried under the geothermal floor by hot water or heating cable whose temperature is not higher than 60 degrees Celsius, and radiate heat evenly to the indoor through the ground. Compared with traditional heating methods, geothermal radiation heating has many characteristics, such as comfort, energy saving and environmental protection. In foreign countries, this technology is not only widely used in civil residences and public buildings such as hospitals, shopping malls, office buildings, gymnasiums and swimming pools, but also in thermal insulation of building systems such as flower beds, factory buildings, football fields, hangars and vegetable greenhouses, and even in outdoor roads, roofs, staircases, airport runways and all kinds of buildings. Insulation of industrial pipelines.
