Anti-freezing arrangement for water circulation system of vehicle

摘要

In the circulation system a water tank (1) with inlet and outlet pipes, valves and a collector feeds a closed circuit (5) including a circulation pump (2), an electric heater (8) and the heat exchanger (3) of the heating circuit connected by snap couplings (9). A separate pipe system (11) contg. water alone or a mixt. of water and e.g. glycol feeds the heat exchanger from a combustor (4) to which fuel is pumped (12) from a fuel tank (14). A monitor/controller (6) powered from a battery (7) operates the fuel pump and combustor, with a link to the circulation pump via a separate connector (15).
