Make : Weil-McLain Model : CG-5-SPDN Series 12 I have the above mentioned boiler which is located on the 1st level of a three story one family house, the area where the boiler is located is insulated. my problem is the very top floor is always chilly and the heating pipes are not as hot as the lower levels. The temperature tops off at 180 degrees with a psi of 25 when it is on. Is that adequate for the limits to heat up to the third floor. any suggestions
