Re: Modern hot water radiators - what do I need?
@Edtheheaterman said
"Keeping things simple is often the best design, then use old school methods to regulate the room temperature as needed. I find that placing the wired thermostat in the coldest room will allow that room to get comfortable, the other rooms that overheat can then be regulated by restricting the water flow to the radiators in the hotter rooms.
If you are designing the system from scratch, you should just do a room by room load calculation and install the proper size radiators in each room. That is the best way to balance the system. One size radiator for each room is not always the best design. Select the radiator to match the room's needs"
And I agree. Put a balancing valve on each rad.

OK interesting. It seems like a good question to ask but what do I know!
Re: Vent placement in home 2-pipe steam heat system
@mattmia2 , pardon me. You originally mentioned radiator "valves", and I understood and responded to radiator "vents". Yes, I agree with you 100%.
In fact, I currently balance the heating in the house by partially closing select radiators.

Re: Carbon Monoxide used for public health
They did not account for all those rotting carcasses. You can turn loose one rat dog and he'll kill 100 in 30 minutes and you'll harvest the corpses for fertilizer or hog feed. They could use CO2 as a simple asphyxiant displacing the O2. The rat will not displace as CO enters because they cannot detect it. If they detect it getting harder to breathe, they may be motivated to move to fresh air where the dogs are waiting. Just monitor the ambient O2 below the knees to ensure the dogs get sufficient oxygen. Once the space is clear, you can ventilate and re-occupy quicker because even if you huff a little carbon dioxide, your lungs will clear it right away. You don't have to worry about the half-life as you do with CO and CO2 does not disrupt O2 binding with hemoglobin the way CO does. As long as O2 is present, it will be transported to the cells. A little short term hypercapnea only makes you breathe a little faster and deeper.

is it approved to use it like that? it seems way too fragile for that application.

I don't think copper tubing is rated for the pressure of the propane bottle, i think at least a first stage regulator needs to be before the copper tubing.

the store involved could not produce service records. That leaves them with no defense.
