heating loft conversion?

[greg72]

I have recently converted my loft and installed one radiator. The expansion tank is an inch or two above the top of the radiator. When the heating is on only the bottom inch of the radiator heats! Has anyone any ideas on how to fix this problem?

If your boiler has an over heat thermostat in you could convert the rads to a sealed system. This would circulate the water through the top rads and solve your problem! You need additional heating components such as expansion vessel and filling connection with gauge with high pressure outlet. This will sort it! If the boiler has no overheat then you are in trouble call a heating engineer!

Thanks, I figured that would solve it but wanted to make sure before I put in the work. Is there any other solution before I change systems or is this my only choice?

raise the header tank?

You could raise the header tank but 50 /50 chance of top radiator filling with air over a few months,would got for the pressurised system as Rydell sugested
If your boiler does not have a high limit thermostat a kit will be able to be fitted
