Hello was looking for help understanding my old boiler, wanted to learn to do maintenance myself on it.

    That boiler doesn't appear in any of our references. What I can tell you is that it was originally coal-fired and later converted to gas.

    Many times these conversions are not very efficient, unless the installer used appropriate baffles. I would bet that a digital combustion test would show this. If that were mine I'd look at replacing it.

    Since the lower door says "Crane Limited" I'll guess that you're in or near Canada, right? Unfortunately, our Find a Contractor page only covers the USA.

    It is a Model 18, 9 sections for Water. Once I am in the office, I can get you the heating area. Don't touch the asbestos! You need a pro asbestos remover. It will cost more than a new boiler install. I had a similar boiler in my duplex over 35 years ago. Of course the baffles were gone. There are two semi circles in the upper chamber and a folding cast iron one over the fire pot. You can find then at Shafter in Montreal. I replaced a similar gas burner with a Economite with electronic ignition. My combustion tests revealed 84% combustion efficiency. I used only an indoor/outdoor reset and no thermostat. My gas bill was nearly half of my neighbours. There are still many of this model and Viking Junior in Montreal. They will out live us.

    I can't believe people keep using relics like that. Isn't it costing you a bundle in heating bills?

    I would bet the loss of efficiency (compared to a new boiler) is not an issue when you factor in most new atmospheric boilers seem to have to be replaced every 10 to 12 years due to rot. It would be an interesting analysis.

    I have one of these in our old house. I thought about replacing it many times, but the cost per month not too bad and it still works great. to get rid of asbestos and the unit would cost lots, let alone replacing rusted out new boilers every 10yrs
