Is the heating giving off too much heat? Search for heat causes in the heating room

Hello,

I have a question about my new building.

The heating system is in the attic in a separately insulated room.
Type: Buderus Logamax plus GB152-16/24/24k

In the heating room it is constantly at least 30 degrees, I have already insulated some pipes through which hot water runs (plumber forgot?), after that it was a bit better but still very warm.

I am surprised by this heat because my parents have a new heating system that does not emit any heat at all. Their heating basement is now cool.

Do you have any idea?
Is this normal?

Thanks!

Hello Jordy
For the condensing boiler to work properly, the room must have a small fresh air opening of about 150 cm2.
Next to the heating/water pipes, which should be well insulated, you also have the flue pipe in the chimney. Since the flue gas temperature is between 50-70°C, the flue pipe (if not insulated) also releases quite a bit of heat.
