Hi,

My boiler shows the return temperature of the CH on its display.
Earlier today it was showing 75(C) which seems very hot. As it is a
condensing boiler won't this mean it is operating outside its
condensing mode?

What is a good solution for this? I don't think the pump is
adjustable.

More info. What make model of boiler for starters and any info you have on
it.
