The tanks for heat pumps are mild steel construction, and the heat pump installer should ensure that the buffer tanks are adequately protected against corrosion from the heating system. Another benefit of the 2-pipe buffer tank configuration is that the distribution system has "access" to the hottest water in the system before that water passes through the upper portion of the buffer tank.
