Technical Specification

Working Pressure

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.
