Dave - Thanks for the help.
NTC = (????? Temperature?? Controller??) - I have tested the resistance and this is varying with temperature change in the Kohm area. Do you know the resistance/ temperature range correlation? (Not a PT100 type device!)
I will check the pot later.
As for...
Right,
Everything was OK and then I noticed that when the Rads are up to tempertaure etc.... the boiler runs for 2 mins and then stops on supposedly reaching temperature! This cycle goes on forever or until you let all the rads cool right down.
I have proved out all the obvious stuff...
Thanks guys,
Really appreciate the feedback - guess I am off the on wrong track but it still intrigues me how a BBOE works given the explanation of hot water rising by by JohnD
The inverse must be true - cold water falls - hence the circulation action.
Many thanks once again - time to...
