    Lux Heat Column Radiators?

    I'm contemplating treating the front room to some aluminium column rads. Looking on the justradiators site there's 1 that fits the bill at nearly 2 metres long. A company called Lux Heat makes the rad I'm interested in. Anyone heard of this make and are they ok?

    Balancing radiators in a 2 zone system

    Hey everyone, Looking advice on balancing the radiators in a 2 zone (+hot water) system. I know you should open all valves and then close the one that heats up the quickest and open again by 1/4 turn, following this pattern for the rest radiators. Is it the same process for a 2 zone system...
