We have recently moved into our house having done a lot of work to the house. One of the works was an entire re-plumb including a brand new heating system (pipes, boiler, rads etc). I am learning about the place all the time and recently I noticed some of the rads furthest from the boiler needed bled. It is a big house and there are about 18 rad in the place. Having bled them I noticed that the lowest 6" of the rads were not as hot as the top. They did get warmer after the system was running for a bit and they did get warm ok, but not HOT like the top of the rads. I am panicking that it is a sludge build up already! On the other hand I am not an expert and don't remember ever paying that much attention to the temp at the bottom of a rad. So for those in the know do rads realistically always get a bit hotter at the top due to heat rising or have I something else to consider like there may be sludge or the system is not properly balanced.
I let the system run for about 20 mins at about 23 degrees on the Honeywell Wireless so I hope that was long enough to get to temp ( the rads had been on prior to me cranking the temp up so it was not from cold to 23 in 20 mins).
Plumber out tomorrow to look a bit of snagging, so, I was hoping for some advice before he arrives so he doesn't just fob me off.
Many thanks for reading this.
