TT PE110 longer run times
I have a Triangle Tube PE110 nat gas boiler in my house. 100 plus year house with cast iron radiators one zone. The boiler is piped P/S with a Grundfos alpha pump set on lowest speed for main zone second and third zone available for future zones. Boiler runs with the outdoor reset control. What is the best way to get the boiler to run longer with lowest possible firing rate when there is a call for heat? I believe the contractor never changed the outdoor reset control from factory settings. This is the fifth winter and with the very cold weather the CI radiators have never been hotter that this year because when it gets very cold outside the boiler is sending out higher water temp to heat the radiators. If the heating curve was set for sending out 160 Deg max water temp when coldest weather is outside would this make for longer run times at lower firing rates? Would this improve system efficiency?
