Boiler returns “throttled down”?
Hello! I’m new here but been looking on this forum for a few weeks now. A lot of good information! I just purchased my first house and it is equipped with single zone OHW boiler with 36” radiators. I have noticed the previous owners has all of the returns from the radiators “throttled down” with the ball valves. I can’t figure out why they would be like this. Are they trying to keep the heat in the radiators longer? I didn’t notice any increase in the pressure of my boiler it’s in the 12-15 psi when running. Any input would be great! Thanks to all and Happy Holidays!
