I'm not a heating expert, but according to the information I could find, Economy 7 utilizes cheap electricty at night, during off-peak hours (7 hours) between midnight and 7AM. Economy 7 costs about 4p per unit compared to peak electricity, which is about 10 to 15p per unit. If you do not have Economy 7, you can request it FREE of charge from your electricity provider. You will either have one meter with two readings or two separate meters. A two tariff electric meter will record the electricity used during off peak times, so it can be billed, separately, at a lower rate. If you have two meters, one meter controls on peak daytime electricity and the other controls your night time economy 7 electricity.

I would need to know what model Creda heater you have installed in order to determine how energy efficient it may be. I also will need the model so I can determine operating instructions. If you need further assistance, please post back and let me know. I hope this helps.

Troubleshooting by Symptom Poor Heater System Performance

1. Start the engine. Allow the engine to idle. Does the engine reach normal operating temperature? If yes, go to the next step. If no, go to step 8.
2. Allow the engine to idle. Select the FLOOR mode. Select the minimum blower speed and the warmest temperature setting. Feel the temperature of the inlet and outlet heater hoses at the heater core. Does the inlet heater hose feel warmer than the outlet heater hose? If yes, go to step 6. If no, go to the next step.
3. Install a thermometer into the center I/P PANEL air outlet. Secure a thermometer to the heater core outlet heater hose. Select the PANEL mode. Select the maximum blower speed. Select the warmest temperature setting. Record the temperature at the center I/P PANEL air outlet and at the heater core outlet heater hose. Are the two temperature readings about equal? If yes, go to the next step. If no, go to step 5.
4. Inspect and repair the cowl, recirc door, and the HVAC module case for cold air leaks. If problems are found and repaired, go to step 9.
5. Inspect the temperature door operation. Perform any necessary repairs. When repairs are made, go to step 9.
6. Turn OFF the engine. Backflush the heater core. Start the engine. Select the FLOOR mode and the lowest blower speed. Select the warmest temperature setting. Feel the temperature of the inlet and outlet heater hoses at the heater core. Does the inlet heater hose feel warmer than the outlet heater hose? If yes, go to the next step. If no, go to step 9.
7. Replace the heater core. When the repair is complete, go to step 9.
8. Repair the low engine temperature concern. When the repair is complete, go to step 9.

Insufficient Defrosting

1. Start the engine, select the DEFROST mode, and select the maximum blower speed. Does sufficient air flow from the defroster outlets? If yes, go to the next step. If there is insufficient airflow, go to step 9.
2. Measure the engine operating temperature. Does the engine reach normal operating temperature? If yes, go to the next step. If the engine does not reach normal operating temperature, go to step 7.
3. Select the minimum blower speed. Select the warmest temperature setting. Feel the temperature of the inlet and outlet heater hoses at the heater core. Does the inlet heater hose feel warmer than the outlet heater hose? If yes, go to step 10. If the hose temperature is not right, go to the next step.
4. Test the operation of the A/C compressor clutch. Does the A/C compressor clutch engage? If yes, go to the next step. If the compressor clutch does not engage, go to step 6.
5. Repair or replace the A/C compressor clutch. When the repair is complete, go to step 13.
6. Repair the A/C compressor clutch concern and determine if the A/C system is operating within specifications. If yes, go to step 8. If no, go to step 11.
7. Repair the low engine temperature concern. When the repair is complete, go to step 13.
8. Inspect for correct operation of the recirculation door. If the door is operating correctly, go to step 13. If the door is not operating properly, go to step 12.
9. Repair the air delivery concern. When the repair is complete, go to step 13.
10. Repair the heating concern. When the repair is complete, go to step 13.
11. Repair the A/C performance concern. When the repair is complete, go to step 13.
12. Repair the recirculation door concern. When the repair is complete, go to step 13.
13. Operate the system in order to verify the repair. If the system is operating properly, the procedure is complete. If the system is still not providing proper defrosting, repeat the entire test

. Noise from the HVAC Module

1. Start the engine. Cycle through all blower speeds, A/C mode settings and temperature control settings. Determine the type of noise, whether it is a scraping, popping, ticking, clicking, chirping or groaning, or an air rush or whistle. Is a scrape or pop noise evident when selecting modes or temperature settings? If yes, go to step 5. If no, go to the next step.
2. Is a tick/click, chirping, groaning or scraping noise present, but decreases as blower motor speed is decreased? If yes, go to step 5. If no, go to the next step.
3. Is an air rush/whistle noise evident in all modes but not all temperature settings? If yes, go to step 5. If no, go to the next step.
4. Is an air rush/whistle noise evident only in defrost or floor mode? If yes, go to step 5. If no, examine for other sounds, repeat step 1.
5. Remove the I/P trim pad. When complete, go to the next step.
6. Inspect the airflow doors for proper operation and the ducts for obstructions or foreign materials. Were any of these conditions found? If yes, go to step 9. If no, go to the next step.
7. Inspect the mode and temperature doors and seals for warping or cracking. Are the doors in normal condition? If yes, go to step 9. If no, go to the next step.
8. Replace the appropriate door and/or seals. When the repair is complete, go to step 10.
9. Remove any obstructions or foreign material found. When the repair is complete, go to step 10.
10. Install the I/P trim pad. When complete, go to the next step.
11. Operate the system to verify the repair. If system operates without noise, the repair is complete. If noise still exists, repeat the entire procedure.

First, feel the heater hoses going into the firewall under the hood. If they are hot, then you have hot engine coolant going into the heater core. If they are not hot, then you either have a bad thermostat or you are very low on engine coolant.

Next you need air flowing through the heater core so it can come out heated through your vents. If the iar is flowing somewhere else, your temp blend door is not moving because the bend door motor is bad or your temp knob on your heater controls is bad. The blend door motor is an electric motor.

------------------------------------------------
Air Flow Control
Air flow control is accomplished in the following manner:

• Primary control is through the function selector knob , mounted on the heater function selector switch, which is part of the heater control .
• The function selector knob has the following positions: OFF, PANEL, PANEL/FLOOR, FLOOR, FLOOR/DEFROST and DEFROST.
• The heater function selector switch combines a vacuum selector valve with an internal electrical switch.

• The vacuum selector valve directs source vacuum to various vacuum control motors (18A318) . Refer to the System Airflow Schematic and Vacuum Control Charts.
• An internal single-pole electrical switch is also controlled by the selector. The switch controls the electrical supply to the heater blower motor switch (18578) .
• The position of the function selector knob determines the manner in which the system will operate.
• Each position of the function selector knob is detented for positive engagement.

Temperature Control
The temperature control operates in the following manner:

• Temperature control of the heater system is determined by the position of the temperature control knob (between COOL-BLUE and WARM-RED) of the heater control .
• This control knob is connected to a potentiometer mounted in the heater control . This potentiometer is electrically connected to the electric blend door actuator that operates the A/C air temperature control door.

• Movement of the control knob from COOL (Blue) to WARM (Red) causes a corresponding movement on the air temperature control door and determines the temperature that the system will maintain.

System uses a reheat method to provide conditioned air to the passenger compartment.

• All airflow from the blower motor (18527) passes through the A/C evaporator housing .
• Temperature is then regulated by reheating a portion of the air and blending it with the remaining cool air to the desired temperature.
• Temperature blending is varied by the air temperature control door, which regulates the amount of air that flows through and/or around the heater core (18476) , where it is then mixed and distributed.

inside you plenum box:

The principle of electric storage heaters is that they take in electricity at night through a central time switch (normally owned by the electricity supply company and usually not controllable by the user).

There should then be a main switch/ fuse box to control the heater circiuts, check for such a box and that it is switched on (This would normally be sited near the electricity meter).

There should be an isolator switch next to each heater but from what you say this is not the case.

There should be some controls on each storage heater marked INPUT with a dial from 1 to 6 or similar then another marked OUTPUT or BOOST.

When you have ascertained the fuse box is on and the heater controls are set to maximum you then have to wait overnight for the heaters to warm up.

the electric motor that open the heat door looses electrical connection there by the door stays on cold / it is located under the a/c heater assembly / which requires removing the whole dash and heater assy// also bleed all air out of coolant system
