Re: Link to news article about heating fuel sources
What was that quote about statistics? There are lies... etc. Nothing wrong with the map. Nothing wrong with the percentages. In completely ignoring differing climates, the variability of access and differences in regional pricing, misleading at best.
Take the northeast and Alaska and their concentration of oil burning vs. other sources. Could it possibly have something to do with no or very limited access to natural gas? Sky high propane prices? Astronomical electricity rates? Consider the concentration of electricity in the south. Coud it possibly have something to do with a remarkably benign winter climate and a need for air conditioning instead? How about propane in the mid-west? Maybe it's favoured by low prices due to extensive agricultural use and no natural gas availability?
And so on. You have to look at the whole picture...

The American Community Survey fails to take into account the number of coal users in the nothern states and Alaska. The number of households and businesses that burn, lignite coal, Sub Bituminous Coal, Bituminous coal and Anthracite coal are growing.

Re: Occupation
I remember the First time meeting Gary Wilson at a Jim Davis & Al D Ambola (RIP PAL) Somewhere deep in Penna . His beautiful young wife was there, met Mark Hunt & Darin Cooke (USAF Iraq & Afghanistan) in person, Jody Litten (Lost Touch). We all found out about this Carbon Monoxide Seminar at HH.COM The Wall. It was a great bonding & weekend of Camraderie, Education, Imbibing till all hours. Gary and I had just went out on our own, so this was 1999-2000ish. At its peak, Triple Crown P & H employed 5 Plumbers 1 helper and an office manager until 2008 Depression. With a Ginormous Mortgage, 3 Catholic School tuitions, after a great 12 year run, I went back to The Union. Very proud of you Gary. You done good, boy, real good 👍. Mad Dog 🐕
Re: Situational Water Hammer
Hello @KarlW,
As much as pressuretrol / vaporstat are relatively simple they certainly have their issues working correctly and holding calibration, if they ever had it. You may be able to re-calibrate it. I suspect in some cases if the system falls into a vacuum the vaporstat diagram may be damaged.
Did you catch "Money-Well" in the one video ?
If you want better control, you may want to look into controls like the Dwyer Photohelic 3030 or similar.
The Down sides;
Cost, may not be too bad, new, new old stock, used on eBay.
You have to think in inches of Water Column.
It needs its own AC power.
You have to install it, connect it to your system.
Up side, You may have much better control of your pressure and differential setings. And / Or maybe just use a timer to limit the run time and duty cycle.
Leave the other barely functional stuff connected as some marginal safety factor and to make the inspectors happy.
EDIT: Forgot the picture.

Re: Risk of cracking gas hot water boiler when adding fresh water
These can be a compromise between leaving the water on or off. https://www.supplyhouse.com/Axiom-MF200-MF200-PRESSURE-PAL-Hydronic-Mini-System-Feeder-6-Gallon
It sounds like you may have added cold water to a dry and hot boiler and it flashed to steam. This may have damaged the boiler.
Does you boiler have a LWCO (low water cutoff). If not, it really should!

Re: Radiant System not heating
That controller is a rebranded Tekmar. If you need parts or instructions it would be easier to get them from Tekmar. https://www.supplyhouse.com/Tekmar-152-Two-Stage-Setpoint-Control-4151000-p
You should be able to see what temperature the sensor is reading by scrolling through the menu. If the temp seems inaccurate you probably have a loose or bad sensor.
If you pull the bottom panel and jumper from 3 to 4 and/or. 5 to 6 the heat pump or boiler should fire if they are operating correctly.

Re: pre-heating with electric tankless
Resol makes a PV control that can determine when there is excess PV generation. Instead of sending it back to the grid at low KWh prices it turns on a thermal tank
so a large electric water heater tied just to a PV array would store excessive PV as thermal for heating
Tie this tank into the heating system as a parallel load. It runs down to the lowest usable temperature, then the gas take over
A simple delta t controller would make that decision. Once the tank gains temperature again boiler goes off line, PV electric/ thermal takes over again

Re: pre-heating with electric tankless
Unconventional, but if it’s truly being otherwise unused, do it! You could also just use an electric baseboard.Simple to do. Often we overlook the obvious. Plug in oil filled is even easier.;

Re: pre-heating with electric tankless
A tank type electric water heater would make more sense than a tankless. It could store the solar energy in the form of hot water slowly, even when water is not being drawn.

Re: Occupation
Now thinking about the 1/6 second dot and seldom missing seeing one for 5 years or so, I wonder what the speed of an eye blink is. I don't recall holding back on blinking while watching for them.
