My Bock oil fired heater seems to have a cement fire chamber. Is it cement
or another material? I would love to rebuild the fire chamber in my current
boiler using cement. However, I'm afraid it would crack from the heat.
Currently my fire chamber is in good condition but I'm thinking about the
future. Any opinions? I changed the fire chamber once. It uses an asbestos
like material. The boiler is 27 years old. Please spare me get a pro and
you'll burn your family down lines.
It is not cement, but a special refractory material; you can buy 50 pound
containers of a pre-mixed product. It may be lined with fire refractory
brick and then coated. There is a regular fire brick such as lining for a
fireplace, and there is a special high temperature material used in boilers.
Refractory cement. The stuff our boiler guy uses is made by St.
Gobain/Norton Co. and is marked MK ll06. I don't know if a plumbing supply
would have it but anyone that does industrial boilers would.
Do it yourself and save!
Good Gosh...you know, you can buy that cement for almost nothing. If you pay
more than $5 a gallon, you paid too much.
BTW, chances are, its not a cement at all, but a Kaowool liner.
