This is the very article I needed. Not only does it explain what each part does in a hotwater/boiler system it shows pictures as well to identify these componants

Each simple definition includes links to detailed articles discussing how to identify, inspect, diagnose, and repair each component of the heating system.
Thanks so much for the nice note, Mr. Harris. If specific questions arise when you read information at InspecAPedia, we'd be glad to hear them - that feedback helps us see where more research is needed.

Question: how to replace or re-line a boiler combustion chamber
(Nov 4, 2012) Anonymous said:
my utica boiler model# sf-3100wt needs a chamber kit is this something a homeowner can replace? how do I know if it needs a wet or dry chamber kit?
A wet pack chamber liner kit is usually a replacement alternative to the factory liner that is often in one larger piece.
The wet pack can with care be installed through the oil burner opening - less labor.
The rub for a do it yourself has 2 parts
If you do not install the liner correctlynthe system can be damage, unsafe, even start a fire
Also because the burner is removed for this job youdnneed knowledge and simple tools to bleed air out of the fuel lines on reassembly.
Question: safety switch trips itself
(Jan 12, 2013) c.p. said:
Is there any malfunction that would cause the service safety switch on our oil fired boiler to trip itself?
Possibly a wiring error, but generally 98% of the time if a boiler is off on reset there is a flame problem sensed by the cad cell or stack relay.
Question: replacingan old boiler, large pipes
(May 28, 2014) Alex said:
Replacing an old boiler.
Alex, for an unseen system I'm nervous about predicting the difficulties involved, but I can offer that I've certainly seen many older hot water heating systems whose large diameter piping, installed to heat by gravity-convection, was left in place successfully when changing to a new boiler with circulator pump(s). The main effect is that there is a greater volume of water in the large-diameter pipe system, more thermal mass.
Question: boiler won't come on
