I currently have a 15 year old Thermodynamics VTF oil fired steel boiler with a slight leak around the tankless coil gasket. I been thinking of replacing it in a few years but I don't want to have a failure in the middle of the heating season and have to rush out and just get another low efficency boiler. I'd rather save up for a high efficency model, add outdoor reset controls, add an indirect HW tank, re-pipe for primary/secondary,change a split loop into two seperate zones, and line the chimney. All this work would probably take more then a day so I'd like to do it outside heating season. Do boiler leaks usually start out small giving you a few weeks/months before major failure, or will a small leak in the presure vessel immediately prevent the boiler from working requiring replacement on the spot? I've heard of cast iron sectional boilers cracking, probably unable to pressurize after that. Does a steel boiler give me more warning or time before failure?
