Can anyone point me in the right direction I have a myson boiler approx 10yrs old with a hot water tank in the loft.Over the course of a week the hot water becomes less hot.The pipe to the tank is still very hot but the return to the boiler becomes luke warm.If I put the heating on it for a few minutes it clears it for a week and the back to square one.
Is this just a simple air lock or is there a return valve sticking or another problem.If you can help with a solution than many thanks.First problem with this in 6yrs
