Peerless WBV versus Peerless ECT

Bobby D.

I am back on the wall after a long absence. Had an estimate for a new oil fired steam boiler to replace my ancient Dunkirk 5 Section (converted from coal?) circa 1947, with a Sun Ray Burner. Yes I know it needs an upgrade.

Of course called my oil delivery provider who recommended a Peerless ECT. Co. Rep. did not do an installed radiation load calculation. Looked at my current dinosaur and recommended a Peerless ECT 04 Section boiler, I added a Riello burner. He stated the company does not install 3 section boilers because of their failure rate (whatever that means) suggesting that the sections expand and contract to much causing premature failure.

He then stated we can downfire the Riello if necessary. I let him go on.

Keep in mind I have added a separate hydronic baseboard zone for my basement using a transfer tank and two circulators (using water from the Dunkirk) that run only when the current burner is not calling for steam. I want this to continue to function as a separate zone, on a separate thermostat if a new boiler is installed.

We concluded that we should continue to use this system but first suggested running the condensate directly to the hydronic system (copper fittings). I stated my concern about running sub boiling 200 degree or more water through circulators and baseboard directly without either a mixing valve or control to temper the water.

Sorry this is a lot of information, I can post photos if necessary, Thank you all for any help.

I think you need someone else who knows what they're looking at.

If you currently have a Sunray burner and going to a Riello, beware of the decibel increase. Maybe look at the BF Riello to keep the noise down if the boiler is under living space.

I've also never heard of a 4 section ECT block being more durable than a 3 section ECT block.
