Gravity System Advice

[Martin2017]

[FONT=&quot]Hi guys[/FONT][FONT=&quot], doing some renovation work in my downstairs bathroom and need some advice.[/FONT]

[FONT=&quot]Since bei[/FONT][FONT=&quot]ng in this house there has always been a radiator half way up the downstairs bathroom wall. I've found out by taking back some false wall that this radiator is joined to the gravity hot water circuit, which I understand was common practice years ago for bathroom towel radiators.[/FONT]

[FONT=&quot]My question, is this radiator placed half way up the wall because it is on the gravity hot water circuit and needs to be higher than the boiler in order to heat up? If this is the case, is there anyway I can get the radiator to work when mounted lower down the wall[/FONT]

[FONT=&quot]The boiler is a b[/FONT][FONT=&quot]a[/FONT][FONT=&quot]xi back boiler, pre 1975.[/FONT]

[FONT=&quot]Thanks[/FONT]
