SOLAR BASED CENTRALIZED ROOM HEATING SYSTEM

摘要

The present invention relates to a solar based centralized room heating system, comprising of: a solar water heater [1] with a backup boiler [2]; one or more pipes [3]; one or more pumps [4]; one or more valves [7]; one or more sensors [5]; and one or more controllers [6]. Outlet of the solar water heater [1] through the backup boiler [2] is connected to the pipes [3] for circulation through the pump [4]. The pump [4] is actuated using the respective valve [7] based on output from the sensors [5] through the room temperature controller to circulate hot water through pipes [3]. The cold water is circulated back to inlet of the solar water heater [1] when the flow temperature controller is below a pre-set temperature. The pipes [3] are insulated and piped under the flooring with high thermal conductivity. Figure 1
