Standard models up to 2.5 bar (2.5kg/cm sq, 36 p.s.i.)
Test Pressure
1.5 x maximum working pressure
Temperature/Pressure relief valve
Supplied with all C-Warm heaters.
Standard pressure: Set to lift at 2.5 bar or 90 deg
C.
High Pressure:Set to lift at 3.5 bar or 90 deg C.
Non adjustable
BS6283 part 3
The temperature/pressure relief valve must be fitted to the heater before it is put into service.
Failure to fit the relief valve will invalidate the
C-Warm warranty.
Working Temperature
The recommended maximum continuous stored water temperature is
90 deg C which cannot be exceeded when the temperature/pressure
relief valve is fitted.
The temperature of hot water available from hot taps
should not be allowed to exceed 65 deg C.
Heating Time
Indirect Cooled Engine
15-25 minutes to heat a full tank from 15 to 55 deg C, depending
on engine cooling water temperature and circulation
rate. For twin coil models, either coil alone will give
a similar heating rate. Both coils in use at once will
heat the water faster.
Direct Cooled Engine
Heating time variable and stored water temperature variable,
depending on engine cooling water temperature.
