Re: Solar paired with phase change material
How about a thermal battery bank using Sodium acetate trihydrate ?
Each Battery can be utilized/Triggered when needed.
I think Sometimes potassium chloride and/or sodium chloride was also utilized but i think the Heat exchanger design may be challenging.

Re: Snowmelt timelapse
Luckily, there's no such thing as "climate change." Using heat to melt snow instead of going outside with a friggin shovel for 5 minutes???!!!! If you can't shovel one inch of snow, Colorado is the wrong place to live.@philsego, this comment is uncalled for and antagonistic. Why start your day by tearing other people down? Please follow site rules and be respectful. You do not know the OP's situation or why they chose a snowmelt system. Snowmelt makes a lot of sense for CO and they're sharing this video because this is the first snowfall to test the system out. It doesn't matter how much snow they received. I appreciate them sharing the video so that we can all learn.
Re: Radiant floor performance troubleshooting
The main reason that residential radiant floors design around a 10- 15 delta is for comfort. You want the floor temperature to be a consistent as possible.
If you run in that 10- 15 range when you reach thermal equilibrium ( supply and return temperature stabilizes) , all is good.
This shows what a 300' loop would look like running 3 different delta Ts. Same 110 supply temperature in 3 examples.

Re: Steam powered saw mill
The Northern Illinois Steam Power Club puts on the Sycamore Steam Show every year. Starts second Thursday in August. When my son was younger I would take him to the show. He now makes steam out of rocks that glow.

This Aultman and Taylor sawmill is powered by belt drive from steam tractors.

The NISPC also has a 1952 stationary Kewanee boiler which runs a 1920 Vilter ammonia compressor. Vintage heat pump?

Re: No heat :(
Hot water and i dont see any leaks at all.You may not see any leaks if the water has already leaked out to zero PSI on the gauge. There are SOOoo many places that water can vent of leave the boiler under normal operation.
What did you do to "restart" the boiler? Is there a flame? Are you getting heat?
You may have a Low Water Cut Off (LWCO) that made the boiler stop when the water level dropped. You may need to add water pressure and maybe even purge some air from radiators.
Need more Info.
Can you post a photo of the boiler to include all the connecting pipes from ceiling to floor? Take 4 pictures one high and one low from the left side, one high and one low from the right side. That way we can see the pipes from different angles in case some pipes are blocked from view by other larger pipes in front of them.

This one will work.
@hot_rod should agree

Re: What do you call that top on a Bundy radiator?
It looks like they called it a Radiator Top.
Re: Clow Gasteam Radiator - Please Help!
The Clow Gasteam heaters are a interesting part of steam heating History. The above comments are unfortunately true far as safety. I have several restored for display pieces. They clean up nicely. Most are given to me rather than hauling them away for scrap. I would like to rescue if this one does not have long term home. See attached display.

Re: Would a "remote Hartford loop" cause any problems?
You don't need anything besides that water seal loop in the remote basement, and a vent on the steam main in there as well. Keep that line in the crawl space as a dry return, and vent it at the boiler or where it turns down.
Re: Old NYC radiator help
@Jamie Hall is right but I'll add a little description to his direction to "just turn it over". If possible, you would rotate the vent one way or the other as possible (righty-tighty would be preferable but may not be possible) until the vent is upside-down from its current position.
This effectively "closes" this type of vent so that it doesn't let the air out next time the boiler calls for heat.
In between calls for heat, the whole system fills back up with air (all the steam condenses) and the vents let the air out when the next call for heat occurs.
But in this cold weather we currently have, they might be running the boiler nearly continuously and this trick only works if the system can fill back up with air between calls for heat...once the system is completely steam filled, you can't stop it.
