Re: Smoke smell in house with oil boiler
You mention that you burn wood, at least sometimes. The smell from a wood fire, or one which has almost gone out, is distinctive. So, for that matter, is the smell of diesel exhaust from an oil burning boiler.
So…
Which is it that you are smelling? The two are really very different, although it is common enough to refer to both as "smoke". More to the point, the source of the two and the causes are completely different. So we really need to know.
Re: Room seems to be stuck in a narrow range of 66 and short cycle.
why do you want it to run longer and less frequently?
Personally I would find a 3 degree overshoot or like a 6 degree swing unappealing.
When I timed that a few times, it was exactly 4 mins every time.
This makes sense because each time it is heating water from x degrees to y degrees in a very controlled environment.
Re: Room seems to be stuck in a narrow range of 66 and short cycle.
@CoachBoilermaker you could adjust the anticipator to run a longer cycle.

Re: Room seems to be stuck in a narrow range of 66 and short cycle.
How frequently does that cycle repeat? If it's only two or three times an hour, it's a bit too often — but the real bottom line is this: the job of the thermostat is to hold the space at or very close to what it's set at.
It's doing that.
I wouldn't complain.

If your Steam Expert was from New England Steam Works you need to look no further.
If not … then this is the Info for a second opinion.
Re: A Heat loss calculator for a simpleton!
I've used this online calculator for our house and have compared the results to heat loss calculated from our actual fuel usage, and it gives reasonable results.
The format on the upper part of the calculator seems to have been messed up by Google ads. Just be sure to input the correct number of heating degree days for your area, and your design temperature, in the upper fields interrupted by the ads.

Re: Circulation issue- lp boiler
"Occams Razor" says that it its very unlikely that you have TWO bad Grundfos circulators right out of the box. Like others have mentioned: put some purge valves on the return manifold of the system side of your LLH. The boiler side of the installation has ALL KINDS OF purge points. The system side is hydraulically separated from the boiler side. It TOO needs to have purge points. Put them in. And then purge. Voila!
Re: Cast Iron baseboard leak on strange fitting
Larrys pex solution is probably the simple best solution if the temp is ok for the pex
Re: Cast Iron baseboard leak on strange fitting
Hi, What temperatures is this seeing? Perhaps a loop of PEX would do the job.
