Check with the company.

Why is your system running at such high temperatures? Typical radiant floor loop systems are limited to 80° degrees or else floor damages can occur. Typical modern boilers for hot water radiators usually get no higher than 130° directly at the output, and the actual radiators are much cooler.

@Delta Systems not a radiant floor system, just a normal hydronic radiator system. Ill check for sure the actual temperature settings I currently have on my boiler, but I dont want people to have the option to burn themselves accidentally. at the output 140 is considered a low temp from what i've read and 180 is on the high end but still normal.

@Elmer J Fudd, Ive called them, no response.

The typical design temperature for hot water in a hydronic, baseboard-type or panel-type radiant heating system is 180F. The temperature can be adjusted up/down based on the system's performance to minimize energy consumption. The temperature of a hydronic towel warmer can be regulated by installing a thermostatic control valve. Runtal sells those to go with their towel warmers.
