2 x 2000 boilers corroded within 2 months from one another. The only alternative was the Xstream tank that CAN NOT CORRODE.

The solution:
10 x 200 litre Mainstream tanks connected in series, each fitted with 2 x 3kW incalloy elements each with its own isolator switch and thermostat.
With a total of 60kW available the reheating time was calculated at 4 hours due to the long pipelines with resultant heat losses 3 x 200 litre tanks were installed at the furthest drow off points. Provision was made for solar connections on the second 5 x 200 litre tanks.
