I think forced air should be oversized. I want each cycle to be over and done with as soon as possible.

Re: The right boiler Best of the Best

@Will82 I currently have a Navien NCB in my house and have had it for 3 years now. With out a single problem with performance and reliability. For the price point it's a great unit.

If I where to do it all over again I would probably install a Lochinvar KHN or a straight high efficiency boiler. The Combi is nice but with Well water I get a bit of temp fluctuation and the wait for hot water is a bit slow for my likings. I just haven't installed hot water reticulation in yet. I've installed a handfull of KHN now and really like them. Plus having the ability to do floor mount is nice.

Re: can I use silicon lubricant on PVC Vent adapter?

ChrisJ said "What caused the flue gas to spill into a home?"

Let me count the ways...

Jenn-Aire grill creating negative pressure, causing flue gases to be drawn to point of negative pressure.

Whole house exhaust fans doing the same thing.

Solid fuel appliance creating so much negative pressure in its chimney that it causes back drafting of gas appliances.

Roofers taking a break on the roof decides to sit on the mushroom cap, collapsing it.

Inexperienced workers dry fitting PVC venting system together for modcon boiler.

Boilers sooted up during construction due to inhaling sheetrock dust, blocking flue gas passage ways with carbon and causing major rollout.

Solid fuel converted appliances with no barometric damper to control draft, causing major spillage.

Severe winds causing the "shower curtain" effect, negating negative pressure and causing spillage from the draft hood.

"Carbon monoxide leaks" are a TV phrase which means in most cases they really don't know what caused it, but the blue bodies are a dead give away that it was CO poisoning. In most cases, the conditions that caused the "leak" self corrected before help arrived.

And these are just the ones that I am familiar with. I'm sure Jim and Tim can probably add plenty to the potentials.

It's not something to be taken lightly, and is the most preventable means of death and inadvertent poisoning.

Don't get me wrong, you're the one that said a manufacturer said to use spit.

I don't trust the "use only our brand of lubricant". I do see @hot rod 's point though when it comes to something going wrong. This is why I asked.

This doesn't mean I don't take CO seriously.

My networked CO detectors are slowly spreading and I have one only a few feet from the water heater and boiler. I also make modifications with great caution when it comes to repairing drafts because I realize I need a lot of air for the boiler and water heater.
