Re: strong smell after boiler install
By yourself some dope. Put a glob of it on one of the steam pipes by the boiler. See what it smells like.
Re: Furnace playing games
Ptoblem solved….I believe so far …..10hrs into it.
i did opt out on replacing the primary with the digital R7284U, and went with R8184 G 4009. Why???. I'm in an area prone to loosing power, and couldn't find any definite information on what happens to the digital if this occurs. I did gather enough to believe that it will have to be reset manually when power comes back on. Not sure what happens with the 4009, but my old model 1032 would still keep going. I don't have faith in digital. Too far in the "boonies", and too much to loose if heat don't stay in the house, even if power only out for 1hr or less. I cant always run home and reset.
If someone has better to say about "digital", Ill listen. If not, so be it, what works for me, works for me.
Thanks for the input I got…..HVACNUT, techforlife.

Re: Heating recommendation for Jackson, WY
There are, or were some excellent radiant contractors and wholesalers in the Jackson area. I've been doing trainings up there for 17 years now.
I would have a local wholesaler, or rep do a design for you. Something like LoopCAD to get a tubing layout, pump sizing, boiler piping, etc.
I would tube every residential job 6" on center now. A little more tubing $$, but it allows you to heat with the lowest possible temperature, give you the fastest ramp up, most consistent floor surface temperature.
Also allows for a heat pump installation in the future.
I can call around on Monday see how many of those hydronic guys are still in the area, or who is the local go to experts, PM me if that could help you.
My next ground up build would be a mix of radiant floors and panel radiators. Really no need for radiant floors in bedrooms, most of it is covered any ways. I'd use panel rads with TRVs in bedrooms. Quick easy control and setback options. A super simple non electric temperature control.
With some attention to design you could run radiant floors and panel rads on a single, low temperature system.
I'd guess a 50- 80-,000 btu/ hr boiler would cover your entire project.

Jump R to W in the Honeywell. If the relay clicks, check your wiring & Nest (we just condemned a Nest with a defective subbase in a different thread). If it doesn't, you don't really have power to the Honeywell or it's defective.

Re: Boiler Running Full Tilt, Cold House
My theory was to let a new boiler run two years, then open it up, regardless if it is a water or fire tube. If it is in excellent condition, go another two or more years. If it is plugged with bugs, pollen, whatever, then a yearly cleaning may be necessary. Gaskets and flame rod/ignitor on hand before you start!
If nothing else a combustion test might indicate something is plugged.
A water quality test is another good idea. Just draw a sample to see the color of the water or glycol. Let it settle to see if any magnetite is present.
The manual may mention yearly service to maintain warranty?

Re: Boiler Running Full Tilt, Cold House
Now i know why i should do the annual maintenance of cleaning the combustion chamber on my HTP. i have sort of ignored it for the 6 years since I installed it but i will do it this summer. I think there is an envelope with a set of gaskets that came with it that i set to the side while installing it. i'm hoping it isn't that dirty because it is only used for water heating and some supplemental heating. The schedule should probably be by hours of run time rather than just time, it looks like there is a way to set that as a reminder in the setup but the manual didn't seem to give hours for the service interval.

Re: Boiler Running Full Tilt, Cold House
Unfortunately you found out the hard way that you need to get to the heat exchanger on a PM with mod/cons whether its a fire tube or water tube. After doing it a couple of times It's really not that hard. Its part of our preventive maintenance with our customers. Every mod/con we breakdown we clean the heat exchanger even if it doesn't need it. We create a maintenance kit at our supplier so that when our scheduled PM's are due we just reorder We never have to change the heat exchanger gasket. The gasket that we carry to every site is the fan gaskets and the rear firewalls on water tubes.
I find it well worth breaking down because you actually will see what's going on in the heat exchanger. I've had leaking heat exchangers on the top of a fire tube and found water tubes completely plugged with coffee grinds. our PM's are pretty fast because they are cleaned annually. I believe that without a doubt doing a complete PM is extending the life of our customers mod/con.

Re: Boiler pressure constantly rises to/past 30psi relief valve trigger
I'm not the expert, so don't do anything without further advice from the actual experts. But I think you have this aquastat:
https://www.supplyhouse.com/Resideo-L8124A1007-High-Limit-Protection-Low-Limit-Circulator-Triple-Aquastat-Relay-High-10-DegreeF-Low-Limit-10-25-Degree-Adj-Differential
If you open that link and click on the third thumbnail pic in the lower left, you'll see it has the same innards as yours, as far as I can see. Your boiler will have an immersion well behind the existing aquastat that the new aquastat's temperature probe will fit into.
But don't order anything until someone who is a heating pro tells you it's the right (or wrong) aquastat.
