Boiler Temperature

[RetiredMT]

How do I know what to set the boiler temperature at for my radiant heat? I know the floor manufacturer states 80 degrees F. But what would I set the boiler temp at?

Depends on floor coverings and design. A wood floor 80° but need to check with the floor manufacturer. A well design floor 5 - 10° over setpoint. Set at room temp 70° 80° water.

On my radiant floor system, the boiler does what it wants and the temperature of the zones are controlled by a mixing valve in each one.

Do you have mixing valves ?

I don't know. But the installer left the boiler to heat to 125 F.

What kind of boiler ? Gas/oil ? Condensing or not ?

There are lots of ways to run different set ups. Can you take a picture and post it ?

Sorry, I guess that WOULD help. This is a 3 year old Lochinvar propane boiler. The model is WHB155n. Also not sure if it matters, but I live at 8000 feet.
