Analyses on Two Paving Types of Floor Heating

Aimed at wet and dry paving types of floor heating, the temperature distribution of the floor structure and surface at the steady condition were discussed by numerical simulation, the analysis shown that the temperature distribution in wet and dry laying methods of floor heating has same influence, That is the floor surface temperature can increase with decreasing layer thickness, with the increase of the average supply and return water temperature, with increasing thermal conductivity of materials and reduce the supply and return pipe spacing, etc. Dry and wet of floor heating methods have each advantages and disadvantages. As a larger the layer thickness of the wet of floor heating, the thermal resistance larger, so surface temperature distribution more uniform, while the dry system is simple and easy to maintain pipeline, especially suitable to existing buildings converted heating into floor heating.
