I presume the hot water heater will be installed in your house an the solar panel on the roof. It sounds like there isnt a storage tank attached to the solar panel, rather, it connects directly to the hot water heater. 1. the solar panel shoud be installed on a sloping roof. if it is a shallow slope tothe roof, you need to provide brackets to elevate the panel so that it most directly aligned with the sun. if the panel is rectangular it should be mounted so it stands TALL.. and not on its side. This will aid in the thermosiphon process of your solar collector. 2. there should be two ports, inlet and outlet. one on each end (mounted top and bottom) cold water goes in the bottom and hot out the top. 3. there should be a drain feature to your system that drains the solar collector at night. you do not want to recirculate hot water through the collector when it is not collecting solar radiation....then it becomes a water cooler. 4. the top port (outlet ) hot should be connected to the cold water inlet of your hot water heater. the bottom port (inlet) should be connected to the cold water inlet of your house or it also can be connected to the cold water inlet tothe hot water heater. what will happen is that water willthermosiphon in a loop through the collector and be drawn off as need to preheat the hot water heater inlet. wer |
