I have a Glow worm Ultracom 24hhxi boiler that has the useful function of easily being able to see the flow and return temperatures.
My boiler has been set up with a target flow temperature of 73 degrees. The difference between flow and return temperatures is around 12 degrees.
What should you expect these to be if the system is operating at it's maximum efficiency?
The heating works well set up as it is but there is quite a bit of flow noise. The pump is set to speed 2 so i'm wondering if i can turn the pump speed down to reduce the flow noise and also increase the system efficiency by increasing the flow and return differential.
All comments appreciated.
