Re: Energy Kinetics System 2000 hard lock out
I finally fixed it. See the schematic drawing.
There is a pressure switch that is a prover to start the burner motor. It has two silicon hoses, one of which goes to the exhaust fan output. There is a hose barb fitting threaded into the exhaust and that hose barb was completely plugged up. It looks like the installer put pipe thread sealant on it and got more in it than on the threads. I believe over time it collected particulate and closed up almost completely. I cleaned it out and it all works now. Thanks to Robert Wickersheim for his help.

Best nest thermostat-Experts recommendations to choose
I researched the best smart thermostats as my energy bills have been getting higher every season and I really want to cut down on costs while keeping the house comfortable. i have been experiencing issues with uneven heating/cooling and it gets frustrating trying to manually adjust all the time. i went through reviews from trusted sources like Wirecutter, CNET, and Consumer Reports and after comparing many options these two kept coming up as the top choices:
Google Nest Learning Thermostat (4th Gen, 2024)
https://www.amazon.com/Google-Learning-Thermostat-Temperature-Sensor/dp/B0D5BBYRJM/?th=1
ecobee Smart Thermostat Premium
https://www.amazon.com/dp/B09XXS48P8/?th=1
however, i am having trouble deciding which one would be better for me and i would love to get your expert advice and hoping maybe some HVAC professionals or homeowners with experience on this forum can also share their advice.
i usually work from home most days so having accurate scheduling and room comfort is important for me. would either of these be more recommended for my situation? Any suggestions or advice would be appreciated.
Thanks in advance

Re: buying a hydronics business
Are Your customers stupid?
A story about the father & son, long standing, “50+ years in business company” that purchased my company. I would write a letter every year to my customers thanking them for their business, wishing them a happy new year and telling them something positive about doing business with me. One year was that the price of the service agreements would not go up this year, another time was that the cost of labor on our flat rate service price book was down 4% and that would be reflected in the new price book, and sited 2 examples of labor only flat rate repairs, like: clean & adjust electronic ignition old price $62.59 new price $60.09. One year I just told the customers that My son was doing great in Track & Field and holds high school records in 5 different events. He was offered a scholarship to The College of New Jersey to be on their track team. But I digress…
The new owner of my customers read a letter I prepared with the "good news" that I was partnering up with the new company and the "good news" is that there will be more technicians available for emergency service calls and more years of experience and several other "good news" items about the purchase of my company by their company. This corny communication was what my customers were used to receiving from me and my son. They often commented on some of my comments in the letters to me and the other mechanics during their maintenance visits, so I knew that many customers read these letters.
The buying company’s father read the letter I prepared and said this crap was too corny to originate from this firm and filed the letter in the circular bin next to his desk. He did agree that my customers should be notified that there was a new owner and composed a no nonsense business letter and mailed it to all my customers on the new company letter head. The majority of these letters went into the customer’s circular file as the letter head and return address on the envelope was unfamiliar. After several months of customers not recognizing the new truck with a different name and different mechanics arriving to service their equipment, Mr. J wanted to know if all my customers were stupid. Can’t they read a simple letter that explains what has transpired?
I just had to agree that he knew better than I about how to operate a business at a profit the way his father told him to run a business. Heaven forbid that I might inform him that a letter with my return address and my letter head would have been a better idea. Even if it was not corny and said exactly what the letter he sent out on his letter head. Jeff knew what he was doing and my customers were stupid for throwing perceived junk mail in the trash.
BOTTOM LINE: If you go through with the purchase, expect to operate the newly purchased company as if there has been no change, and you are just the new guys that work for the existing company. Answer the phone the same way the previous owner answered the phone. Send letters and invoices out using the envelopes with the company name and address the customers are used to. Change the name slowly over time if that is your intention.
Consider not changing the name at all and tell your customers that you purchased the new business and let your customers know that you will be sending letters and correspondence with the new name. You are growing and becoming more successful. Ray Kroc did not change the name of his company after he purchased it from the McDonald brothers in 1962. Somehow I don't think I would like to be eating a Big Kroc, even if it did have two all beef patties and special sauce. What Crock of stuff did that special sauce come from anyway?
Re: Why don't we pump away from expansion tank on dhw recirc systems?
I'm sure many better educated than me can go into better detail. With a recirc on an open DHW system, we don't have a fill valve located at the expansion tank, and since the system is open we aren't going to be eliminating entrained air from the system. For my knowledge these are two primary advantages to establishing a proper PONPC in a closed loop hydronic system, purging air and maintaining proper fill pressure when a fill valve is present. neither of these are relevant really in an open DHW piping system
On your tank mixer documents you would see your choices for tank location are either on the outlet hot port, or the inlet cold port, both on the tank side of the piping, you can't locate it past the mix valve because the valve can become isolated from the burner, and you have to locate the recirc in the location shown. Of the two available locations to pipe the expansion tank, the cold side is preferred because the tank should have a longer life being subjected to lower water temperatures, and prevents the tank lining from being damaged in the event the water heater overtemps on the hot side.
I'd love for someone maybe a bit better educated on the subject than me to chime in, this is all from my understanding of the PONPC I typically don't dabble in the DHW side of things and usually stick to closed loop so there may be things I don't fully understand at work here also.
Re: buying a hydronics business
For the large amount I would want to see his client list, and financials showing what he has paid himself.
Do you get the company name and phone number?
How many hours a week does he work for that salary?
Tools, truck, inventory?
40 hours a week, 50 weeks a year= 2000 hours
So you need to add at least $50.00 and hour to your labor rates just to pay him
If all three if you want 100k a year, $150 per hour per billiable hour just for salary.
Its doubtful you will have that many billable m, productive hours a year, so maybe pushing 200 per hour
Here is a really good deal 😁 to maybe help with some number crunching

Re: Any plumbers good at small bathroom layout?
lack of counter space would be a non-starter with my wife. A shower instead of a tub would be another option.
How creative do you want to get??

Re: Hodge Boiler Plant Photo (1890s)
Seeing how you mentioned paint I just got back from Cape Cod for 2 weeks. They have the Bourne Bridge and the Sagamore Bridge they want to replace (only two bridges access the cape) and they get LOTS of traffic. All riveted 500 + feet each built by Bethlehem Steel in 1935 and shipped to the job in pieces. they are in good shape but are very narrow, I guess 1930 cars were smaller.
but back to the paint.
They also have the Cape Cod Railroad bridge that spans the same 500' wide CC canal. This doesn't have enough clearance for big ships to pass so they raise and lower the bridge with electric motors. It's the second largest vertical lift bridge in the US, i think. It has 1000-ton counterweights at each end. i forgot what it weighs but it's a lot.
But back to the paint.
I guess because the bridge and the counterweights have to be almost perfectly balanced so the motors don't have to work as hard
Every time they paint the bridge, they have to scrape all the old paint off

Re: I get all the weird ones...
"They need the door open for several reasons, they bring the material in with a loader, and then it gets placed with a 308 CAT excavator onto the conveyor. So they want the door open for the fresh air (i already told them bad idea) but also they run that loader in and out about a 100 times a day"
What a god awfull idea. Running a diesel engine inside a building.
Why don't they do things the normal way. An overhead trolley crane with a grapple. Staging area outside for unprocessed material. Crane moves material from outside in through a small opening right to the conveyor. Forklift inside for handling the bales.
