Re: Do old radiators lose efficiency?

I never heard of cast iron losing efficiency, but the older I get I seem to lose some. Perhaps some auditors have lost some too.

Re: The case of the steam filled room. this Friday's case

We should strive for accuracy. A steam-filled room would be invisible and would cook you very quickly. The room was full of condensed aerosol water droplets

Re: Bridge Collapse

..... I drove US 13 a couple times. It is a longer drive. I think I'll get over my repulsion to flying.

It should actually take less time now that traffic is messed up in Baltimore.

Re: New type of 100% efficiency furnace?

It doesn't look like an electric furnace.

I bought a Burnham Boiler for a steam system in Brooklyn, NY in 2021. The heating system is flaky and really annoying. When temperature demand was constant at 68 degrees, it functioned fine. However, when I moved to a daily programmable Nest Thermostat, the heating became flaky. Sometimes it did what the thermostat asked. But from time to time, the temperature would not come on into a warm mode in the morning, e.g. go from 65 degrees to 72. I would wake up and find the furnace cold. On other times, it could not maintain 65 (one one occassion it went down to 55). Only power on/off on the furnace or touching the contacts. restarted it. The same flaky behavior occurred when using an Emerson thermostat, the only difference being the programming is M-F and Sa/Su only. This behavior continues to occur. Now I am being told that the thermostat is still the issue. They want me to try a third thermostat. That seems completely ridiculous. How many thermostats do I have to try before it's evident that the furnace has an issue? So... seeking advice on people who have seen Burnham boilers not acting properly in this manner. Is the ignition suspect? Is the wiring faulty? I know some other Burnhams were recalled. I want an HVAC opinion from someone who knows Burnham. I do not, I repeat, do not want to be told to change the thermostat.
