Re: Negative DC Voltage?
Negative DC Voltage?
Why all the negative talk? Everyone is always blaming the other guys... Electrical engineers are blaming the equipment designers. On the job technicians are blaming the electrical engineers... Democrats are blaming Trump. Republicans are blaming Biden... and nothing is getting done... We need to STOP all the negativity!And we should all start with DC Voltage.

Re: New Zone for Hot Water Heating
I have a two zone hot water heating system with a circulator pump on each zone. I added a new branch (for a new radiator) to Zone 2 with a tee on the radiator side of the circulator pump. But the hot water won't flow into the new branch on its own (path of higher resistance?). It works fine when I isolate/shut Zone 1, but not when both Zones are running.Based on the description above This is the drawing I come up with. There is something missing.
Can you make a drawing on paper and take a picture of it with your phone and let us see what you are talking about?
OR
Tale a picture of the Tee fitting you connected the new radiator from far enough back to see where the pipes are going. Boiler picture from floor to ceiling so we can see all the near boiler piping including the TEE you are talking about.

How do you know there's no flow?
Re: Gas Smell on Start of Gas Boiler - Columbia MCB-170J
Another cause of the gas smell could be that the chimney is down-drafting whenever there is no flame in the boiler. So a perfectly good (non leaking) gas appliance may release gas into the room because the chimney air is pushing the air flow the wrong way. On start up that air mixes with the gas to the burners for a few seconds before ignition and ends up in the room. Once the gas burners ignite, the odor is burnt away with the flame. The byproducts of combustion may or may not enter the boiler room for some time until the chimney warms up and provides the proper draft for the removal of the byproducts of combustion.
Someone with a draft gauge designed for testing chimneys will be the best professional to find out if the poor draft or down draft condition is causing your odor issue. The gauge is inserted in the vent connector pipe before the appliance is turned on to measure the off-cycle draft. Once that reading is known the burners are ignited and the draft gauge is observed for any change in the chimney draft.
Only then can you be sure of the chimney situation. Just a simple cigarette smoke near the draft hood smoke direction is not going to give you the numbers. Chimney professionals or HVAC professional or an Oil Heat Technician may have that gauge. Here are the three most popular draft gauges.

Not enough hot water
I have a friend who has an old cast iron steam boiler. Running out of hot water. I suggested Cleaning the coil like I always do with an acid pump and sizzle. Hard water and all. He is going to put in a thermostatic mixing valve in when problem started not longer ago. I saw boiler its aged close to 40 years has separated high and low limits switches. Boiler is older than triple aquastats. I think sizzle through your coil w/ acid pump would be the route to go.. Anyone else have an opinion??
Re: Phasing out of r410 and what’s next r 32
pressures start to get crazy also in high pressure refrigerant systems, 300-400 psi? Some of the ultra high pressure 700 psi plus!CO2 is very high pressure. Still it was used over a century ago. With today's technology it's doable. An advantage of a cascade system is that the compression ratio for high pressure fluid like carbon dioxide can be modest.

Return of the lost radiator- removing a plug
I'm looking to re-add a radiator (one pipe steam) that was removed from my kitchen some time ago- maybe 15-20+ years ago. This plug seems to be where the original supply went. I have to imagine it's sealed shut at this point, but maybe not?
I'm tempted to try to open it up after heating season and pipe it myself- everything's easily accessible - but I'm afraid to damage the pipe or the encapsulated asbestos lagging.
How would you do it safely? I'm not opposed to calling in a pro if I'm likely to cause more damage to the main, but it seems like a fun project. Or a quick way to inhale some fibers.

Re: Has anyone used Lochinvar's Wireless Outdoor Sensor, or similar?
I installed it today. Doesn't work. I have to go through it tomorrow with HBX. It stops reporting the moment we leave the boiler room with the outdoor unit.

Re: New Boiler Proposed By Contractor- What Info Should I Know?
Thanks Jughne and Hot_water-fan!
Jughne, yes it is a Munchkin. I has served us pretty well over the years. I see now on the label below it was made in 2005. I took the photos you requested (I hope I did..). I also included a photo of the pressure gauge. I remember now that the technician did say that he thinks that the relief valve is "probably very corroded. That's why it isn't opening and releasing water at this high pressure". But the condensate drip line is pumping out steam.
I just measured the entire house and there is a 236 feet, 5 inches of baseboard.
Hot_water-fan, the closed system info is interesting. So you mention a leak of some sort. I do know that there was/is a drip coming from the red handle of the hose faucet (on the right "out" vertical pipe). I saw puddle of water there this morning. I tried tightening it as much as possible and think it may have stopped.

Re: New Boiler Proposed By Contractor- What Info Should I Know?
Is that a "Munchkin" Boiler?
You could shut off the power and loosen the two screws in the lower front panel and remove the top.
The product tag would be perhaps on the left side on a steel flap. Picture is good.
Then inside on the upper right is a pop off relief valve, it should have a tag stating 30 PSI. Picture again.
If you truly had 60 PSI in the boiler that relief valve should be peeing all over your floor, assuming it is piped correctly.
The grey expansion tank has an air valve under a plastic cap, remove the cap and depress the air valve just to see if water comes out.
Your auto fill valve is near that. Pictures also.
If either of these things fail you could replace them and use those items for a new boiler if it come to that.
They do not come with a boiler and are accessories added as boiler is installed. You could show a new boiler installer your receipts and if they would not reuse them I would send them away.
How many feet of baseboard heaters do you have in the house?
