    To be honest, I feel better informed of how my heating works than I ever have. That was extremely helpful and well explained. Thanks a lot!!

    I have watched a few videos explaining the same situations and this for me is the clearest and most straight forward. Well done and keep up the good work👍🏼

    One important tip I missed in this video is that if a radiator stays cold it could be due to the Thermostatic valve being stuck. This mostly happens on radiators that are not used very often or were not used for a long time. Just remove the thermostatic knob like shown on 1:26 and use some (penetrating) oil on the valve while pulling/pushing the valve in & out with a plier. After this, screw the thermostatic knob back on the valve like show on 1:34. Simple and only takes a few minutes.

    Incredibly helpful video and diagrams are excellent. As others have said, learned more in a few minutes here than several hours of other videos on YouTube. Spot on

    It's recommended to disconnect the filling loop hose because you could have a passing/leaking valve that could continually fill your boiler. Disconnecting the loop will help you spot any leaks.

    An excellent way of explaining how they work. The part about the balancing is what I think is wrong with mine. I’ve replaced the radiators one by one since moving in and some of the new ones no longer heat up. I’ve opened all the lock shield valves fully thinking it will increase the flow of water but that’s where I’ve gone wrong. Next thing is to balance them and increase the water flow to the ones furthest away from the boiler. Thank you for making this video 👍🏻👍🏻
  • Simple, clear instructions. I’m off to sort my radiators. Thank you!

    Very clear video, thank you. My new home has floor heating on ground floor (where the thermostat is also installed), keeping the temperature very steady. First and second floor however are radiators, 4 pieces in total, 2 of which remain more or less luke warm, never more. Also, the other 2 are cold at the bottom which tells me the temperature drop (delta T) is too great for the boiler to sit in its HR range. Where do I begin correcting this?
