PROJECT requires a 700kPa line pressure before you even start thinking about friction losses and residual pressure for your fittings. So essentially you require 700kPa to get the water to the top of the building. This meant that the hot water boilers also needed to withstand a 700kpa pressure. The hot water boilers supplied by SA Heat Pump, are rated at 950kPa, which is a greater requirement than the norm, which is around 600kPa, and so these units operate nominally at 950kPa and have been tested to 1 500kPa.
