Hi, I just bought a 100 year old "arts and crafts" style home and am thinking about replacing the 50 year old oil boiler with a new gas boiler. The chimney for the existing boiler is falling apart and needs to be relined so rather than spend the money to reline the chimney and replace with another lower efficiency boiler, I've been told that it will be a similar total cost if I install a high efficiency boiler that direct vents to the outside.
I've talked to a number of contractors, and they all seem to have different opinions:
- one doesn't like the new high efficiency models because they only last 10-15 years. He recommends that I go ahead and fix my chimney and use the existing boiler until it actually stops working, then replace with a cast iron model because they'll last 30+ years.
- one thinks I should go ahead and replace with a newer system. I shouldn't worry about how long the high efficiency units are going to last since they've been using them in Europe for a while. They're made of stainless steel so they'll be fine. He recommends a Pinnacle boiler.
- one is not sure how long the high efficiency units will last, but the heating cost savings should be substantial enough to justify the upgrade even if I have to replace after 15 years. He doesn't like Pinnacle (which he says doesn't make sense to buy anyway since it's the same boiler as the cheaper Munchkin only rebranded by Peerless). He likes Knight boilers.
All three of these guys seemed to know what they're talking about, yet they all have such differing opinions. I'm not sure who to believe or what decision to make. Can anyone provide some insight or additional feedback?
Any help or information is GREATLY appreciated!
