Central Heating not working on gravity system

[zakc]

Hi all,

I have a gravity fed system with a boiler in kitchen, hot water storage cylinder in first floor cupboard and tanks in loft.

The hot water works fine but the central heating isn't. My knowledge of plumbing is very limited and i'm hoping its something simple. Any help and guidance is gratefully appreciated, my ears are beginning to hurt from the other half !!

Pump is the 1st place to look.Is it working?Is room stat up?etc.What do YOU mean by gravity?

Is the pump working? Remove large screw in centre of pump (some water will come out) Once large screw is removed turn the slot in the pump with a screw driver to see if it is spinning.
