Recently converted in floor heating system in newly purchased house to hot water baseboard system; boiler is propane fired. When thermostat is turned up the circulator starts and is then followed by the boiler firing up. Maximum boiler temperature achieved is 115 degrees Fahrenheit, resulting in cold house. It appears that the circulator pump is running continually. I understand that for baseboard heating to be fully effective the boiler should be operating at a temperature range of 160 - 180 degrees Fahrenheit. Would the circulator pump running continuously be the reason for not achieving the proper temperature range? Any help with this would be much appreciated - Thank you.
