A coilable solar water heater includes a heat collecting plate and a soft pipe. The heat collecting plate includes two heat collecting layers, capillary tissues, two protecting layers and a soft support body. The heat collecting layers are stacked with each other and form a plurality of passages at intervals between the heat collecting layers. Each passage is provided for passing the capillary tissues. Each protecting layer is stacked on an external surface of each heat collecting layer. The soft support body is attached onto an external surface of a protecting layer. Each soft pipe has a plurality of through holes, each being connected to a passage of the corresponding heat collecting layer. The solar water heater can be coiled and folded to reduce its volume significantly and facilitate its transportation or moving.
