Hi all. Wonderd if you could advise on the following as you've been so helpful. My system heats up perfectly. Perfectly meaning that all the rads heat up at the same time although they do take along time as there the old school column rads style which I believe hold alot of water. My question is when I've measured the incoming and outgoing temps to balance the system using an infrared thermometer, the flow and return temps are almost the same all the way round despite the wheel being cranked down to 1/4 turn on some and fully open on others. As I said the system heats up evenly and all the rads get equally hot. Is there any negative effects to having an even flow and return temp in which case I can go round and turn them down or should I just leave them. if theres no negatives Id rather leave well alone. Thanks in advance.
