multipoint

In telecommunications, point-to-multipoint communication (P2MP, PTMP or PMP) is communication which is accomplished via a distinct type of one-to-many connection, providing multiple paths from a single location to multiple locations.Point-to-multipoint telecommunications is typically used in wireless Internet and IP telephony via gigahertz radio frequencies. P2MP systems have been designed with and without a return channel from the multiple receivers. A central antenna or antenna array broadcasts to several receiving antennas and the system uses a form of time-division multiplexing to allow for the return channel traffic.

    Heatrae Sadia Multipoint 10 Overheating water

    Water from the tap that this feeds is scalding hot. I've checked the Aquasystem 2 litre expansion vessel that's associated with it and there's no pressure in it. The safety valves seem ok. Would this lack of pressure in the expansion vessel cause the water to become extremely hot?
