Hi, we have a new megaflo type system installed. Bosch system boiler ground floor, cylinder in the first floor. I appreciate that it may take a while to heat up the system from cold and the house eventually gets warm. However, I have noticed that most of the radiators are cooler at the bottom and warmer at the top. I have bled the radiators etc but no improvement. All radiators are double. There is also an underfloor system running independently (through the same boiler). Boiler is 27kw capacity and cylinder 300L.
I have read that cooler at the bottom could be a symptom of sludge but this is a new system with new radiators. Any ideas what might be wrong? Pressure looks normal and hot water is good btw. Thanks very much.
