The performance of a built-in storage water heater can be improved by using a baffle plate in the absorber tank. We have studied the following different design conditions: 1.(i) a water heater with baffle plate and with night insulation cover,2.(ii) with baffle plate and without night insulation...

In this paper, the design of a triangular built-in storage-type solar water heater with transparent insulation on the top and sides is studied under various operating conditions. The transient performance of the system is studied by using a finite-difference forward time-step marching technique....
