ABSTRACT:
In a solar heating system, using liquid for heat-transfer or heat-storage or both, the liquid may be lost slowly due to a leaky pipe connection, or a cracked or split absorber plate or collector pipes attached to the absorber of a closed type of collector, by evaporation through broken solar collector glazing of a trickle-flow collector, or such.
A number of schemes have been proposed to provide makeup liquid. One is to allow makeup liquid, such as water, to flow backward from a large heat-storage vessel used during the winter to a smaller one which is the only one in use during the summer. That scheme was disclosed in a patent application filed by Dr. Harry E. Thomason way back in 1961. However, the backflow-connecting pipe had no check valve in it and therefore was of limited value. The present invention resides in several features including placing a check valve in the connecting pipe, and/or placing a flow-restricting device in the interconnecting pipes, and/or using a hole semi-check valve or lightly-loaded pressure-relief valve in the piping, or such, to increase the value of the system as will become apparent hereinafter.
