The advantages, design principle and technique main points of individual metered heating system in which heat flowmeters are centralized in a meter well or room are introduced.

Owing to the fact that the vertical one-pipe-series-loop heating system for existing house in China is not closed loop system,the metered heating can be realized only by heat cost allocator.

It is point out that the determination of heat rates, collection of heat tariff and mode of heat metering for metered heating system are related each other.

A study on the structure, main devices and working principle of a variable differential calorimeter used for metered heating is made.

Discussion on several problems during implementing warm heating meterage;

Hydraulic calculation for vertical heating systems for household heat metering;

Design and installation of central hot water heating systems;

Discussion on low temperature water floor radiated heat-supply system;

Combined with practical practice,it introduces heat-supply designing course of the first period project from aspects including heat and power centralizing heat-supply system,heat-supply burden and fixing of heat and power substation service radius.
