How are crown boilers? I thought I was up on oil fired equipment but I am hearing about some different stuff. Most of the time people switch to propane or natural here.
As stated above, the Bryant boiler is made by Dunkirk and is a descent boiler. I would personally put it above the Weil McLain. They both are vertical sectional boilers that use pretty tight pin spacing to allow better heat transfer. They both can become soot monsters. The Weil McLain can had refractory issues over the years as it is more of a skinnier shorter flame design. The buderus is a 3 pass boiler and uses horizontal sections. They are 3 pass boilers, European designed, and the cast iron has silicon formulated into the metal which allows for better expansion and dramatically reduces the chance of casting failure related to thermal shock. Maintenance is considerably easier. If you were investing $100 in a new pair of shoes I would say take your chances. I am sure up will be investing upwards of 50x that cost and you are investing in apiece of equipment that will last you 30yrs. Just my $.02
This spring I split a weil McLain and it was basically plugged, there too hard to brush out and have poor access in areas. I like the crown 4 pass, almost enjoyable to maintain.
Why is it no one even mentions Viessmann. same price as the buderus and beautiful to clean and service and very efficient. None of the American oil boilers are newer than 1950s technology and i don't know anyone who actually likes cleaning a WM, Dunkirk, Slantfin etc.
