Re: ignition control on an oil burner
You're right. But that V-74 was made before we had 15-second primary controls with purge periods.
Any of the current electronic primaries is better than that R8184G. They all cut the ignition off after the flame is stable. But to use the purge periods, you need an oil delay valve. This can be part of a new fuel unit, like the Beckett CleanCut, or can be added on like this one:

There's nothing wrong with bringing these older burners into the 21st Century. The pre-purge, also called valve-on delay, goes a long way toward cleaning up the startups. The post-purge, a.k.a. motor-off delay, cleans up the shutdowns. That means less brushing and vacuuming at the next service, and increased efficiency for the customer.
Re: Has anyone seen this? New home owner
Hi, I'd also have the inspector have a closer look at the dark areas above the fireplace doors. Is that smoke? Do the doors leak smoke into the living space?? 🤔

Re: Has anyone seen this? New home owner
Maybe the inspector would have a better idea what it actually is, a TV coax or a power cord for a fan or circulator for the fireplace insert.
Have the inspector look at it.

Re: Has anyone seen this? New home owner
the pipe for the heating loop going through the hearth isn't an issue as long as it is isolated from the masonry so it doesn't corrode or abrade. i have more questions about if there are correct clearances from that fireplace and vent to combustibles

Re: The Result of Using Non Barrier PEX
I would run a hydronic cleaner, Fernox, Rhomar, Adey, Axiom. I think they are all similar. Then use that brand conditioner. The conditioners have oxygen scavengers in them to deal with O2 ingress.
However you need to check it every years or so and probably add a boost of the inhibitors. The inhibitors get "used up" consuming the oxygen.
Use the test kit from the chemical manufacturer. They all offer test kits.
The lower the temperature that you run it, the lower the O2 ingress.
Or isolate everything with non ferrous components as @Derheatmeister suggested.
Is it a water heater as a heat source? If so it is a glass lined tank so maybe just an Extrol Pro expansion tank and stainless circ? I don't see the steel header?

Re: The Result of Using Non Barrier PEX
I would recommend replacement of any ferrous materials for Brass,bronze and Stainless steel. A magnetic filtering device which is not made off ferrous materials would be a great addition as well.
The Result of Using Non Barrier PEX
For those who still think that it doesn’t make any difference whether you use O2 barrier PEX, look at the rust and sludge in this water.
This is after 8 years and the only iron or steel in the system is the the pumps, two steel headers, and the expansion tank. The rest is copper or non barrier PEX.
This was one of several buckets full and I still haven’t finished flushing it.

Found the link
The store energy at up to 600c using a closed loop fluid and heat exchangers. If water is the fluid this is comparable to temperature and pressure used in modern turbine steam plant.
