I have a 235,000 btu Steam boiler that has a slight leak in the tank so i have to replace it what brand boiler is reliable and will last. The one i have is a 19 year old slant fin that i thought would have lasted longer it still looks new. Which ones are the better ones that are reasonable in cost. I was told by someone in the business that they are all pretty much the same but im not sure. Let me know i dont know that much about boilers i had fixed them and installed them before but i don't know what is a good unit anymore and this time im going to have the job done by a plumber if they are reasonable.
