Tiggey, welcome to the site.

If both your heater pipes are cold you might want to check that you duo valve ( heater control valve ) is working corectly. You will find it behind the firewall, on the side of the car by the fusebox. You will see the heater hose going to it. IIRC it has a thin red hose going to it, It has a round white plastic centre, which has a slot in it.

If you get somebody to sit in the car and turn the hot / cold heater control you should be able to see it turn properly.

These are worked by a vacum and are known to give problems. I had a cold heater.....took me a long time but eventually I got it fixed. It can take a while, you simply have to try one thing at a time.


Mike.
