I can only comment on the system I know, which is the protection system used on a typical tanker (a lot smaller area to protect than a house!). For that space, the water usage is 150 litres/minute, and additional passive shielding is added, such as the vehicle body and reflective curtains for the windows, as well as individual protective clothing.
an Australian Standard fire hydrant is to supply for 300 litres/minute at 700kPa and should be supplied from a system 4 hours supply with positive feed.

Melting is a bigger problem as Al melts below 650C depending on the other elements in the alloy, as pure Al is almost never used, so 550C and cooler is found. Steve previously worked in the fire protection industry
