Dead Men Tales: The Illuminating Beginnings of Gas Boilers

" I like to think of myself as a recovering competent-authority nowadays." Things do change. Wonderful!! And thanks.

Yours, Larry

Dan... Are you attending AA meetings? As a recovering Authority, you may find them helpful . I think competent Authority Anonymous has meetings at old boiler rooms and Tobacco sellers in just about every town.

PSEG was expert in gaslighting of both the literal and figurative sense!

And within a year, we were in the midst of a different pandemic! Enter in the era of oversized boilers so we could open out window to fresh air in the winter. Great story Dan!

Isn't it true that they did not have the infrastructure to supply enough gas to use for central heating in 1917 if they were to get a large number of their customers to convert since they whole system from the gasworks to the individual services was sized for lighting and cooking? Maybe that was part of why they weren't pushing central heating.

This brings up another question. How did the word "register" become the word that describes a heating or cooling vent opening?

If you read the Gas Engineer's Handbook, you'll see pages of breakdowns on mfd. gas from city to city. The source of the coal being gasified had huge impact on the constituent gases contained. One species did average about 40% of all coal gasification: carbon monoxide. There was a melodrama from around the 1930's where someone asphyxiated a victim by leaving the gas 'on' at the kitchen stove. Natural gas is not toxic and being lighter than air, will rise and dissipate. CO is just slightly lighter than neutral so it rides the air currents in a home. If there is a natural recirculation flow, CO can remain at lower levels rather than quickly rising up through the home. The reason thousands didn't die every night from fugitive mfd gas is the homes leaked like a sieve. Their ventilation rates were well above 5 ACH.
The 1920's were interesting because they saw the advent of the circulator pump for forced hydronic heating, the move away from coal towards liquid and gaseous fuels, the advent of terra cotta flue tiles, the introduction of Portland cement mortars, the mfr and acceptance of refractory cements and mortars, the first chimney codes requiring lined chimneys with a 1" clearance to combustibles and 3/2/10 height above roof rule, and greatly accelerated engineering, research, and codification of mechanical systems, standardization of parts, measurements, metallurgy, and the beginnings of failure analysis along with the electrification of homes and heating systems. The insurance industry started the move towards standardized building codes at the turn of the century through the underwriter's but it took about 20 yrs to really begin to kick in and municipalities to really begin to embrace things like boiler inspections, safety controls, etc. As with so much of mankind, losses drive changes. Just ask Hammurabi with the first building code, in Babylon.
The part II of this journey would be in 1973 when Israel was attacked in the Yom Kippur War, the US supported them and the Arabs retaliated with the OPEC oil embargo triggering fuel shortages and rationing, lines at the gas pumps, and hyperinflation of fuel prices. The result was a seismic shift in construction with the real advent of weatherization attempts, though crude by today's stds. Two things arose right away: condensation on windows and fireplaces smoked. What we didn't realize right away was we had turned our homes into terrariums and therefore unsuitable for atmospheric chimney venting. Yet despite this radical change in the structures, our codes still allow silly things based upon pre-Ozzie and Harriet home construction. Atmospherically vented gas water heaters are still allowed but still are not required to have spill switches interlocked to the gas control. Forced air furnaces are allowed to have filter slots in the CAZ without an interlock switch even if it is a confined space. 80% furnaces are allowed to be common vented with draft hood equipped appliances, thereby defeating 3 primary safety controls. Aluminum chimney liners are still legal for CAT I venting. Ductwork is still allowed to exit then re-enter the conditioned space. Heating systems are allowed to be replaced without weatherizing the home first or sizing/ sealing duct system then actually calculating and designing the proper system rather than replacement with similar oversized equipment in leaky homes with undersized leaky ducts. Techs still sell 90%+ communicating systems then enter an attic through an un-weatherized 1/4" plywood hatch. I could ramble on more but you get my drift. How far we've come but how far we could go in short order.
