I am changing out a weil mclain 366e or 466e cast iron boiler that has sprung a leak in fire box, I intend to go with natural gas as it is now available,and I`m tired of the maintence needed on the oil models. Most service men in this area shy away, if you say oil boiler, better of doing it yourself, well the weil mclain lasted just over 25 yrs, some very abusive ones. I fire now with a 90 degree 1 gph nossle, the pump is constant on, using about 650 to 700 square ft of old style radiators on five seperate up and down zones with just manual balance at boiler. The gallon an hour on oil is sufficient I have used as low as .75 gph just got longer burn times.How do I size the new gas unit, I`m thinking I need about 140,000 net out put to be on safe side. Will be installing a another weil or a burham. I am planning on using a bypass to stop condensation. I`m just not able to get a real good answer from any body that I can prove my self I can guess as good as any one.
