The Performance of Under-floor Electric Heating System with Latent Thermal Storage

Abstract

This paper illustrates a structure of electric floor heating system with latent heat thermal storage plate. This system can charge heat by using cheap nighttime electricity and discharge the heat stored at daytime. A theoretical model is developed, which can analyze the thermal performance of buildings applying such system in winter. The thermal performance of the heating system and the effects of various factors on it are analyzed by modeling and simulation. For a given room located in different climate regions, the optimal effect of using such system is predicted, which testifies the feasibility of this heating mode in different climate regions.
