Re: The "equalizer" is mis-named. It does nothing to equalize anything.
@delcrossv thank you! I was hoping to use the two 90s had. Guess will have to buy 45s ;)

Re: Single pipe radiator
@delcrossv, I was hoping there was some long lost ancient steam secret that would unlock my hopes.😂

Re: Single pipe radiator
Need some pitch. The takeoff from the end of the main pretty much guarantees water in the lateral.
Is that main counterflow? If not, it needs to go to a drip or crossover trap- not a supply line.
If you're feeling frisky, repipe it as 2 pipe like the rest of the system. 😉
Re: Oil Boiler Water Marks on Side of Unit Behind Paneling, Cast Iron
If I could predict the future, I'd be rich! I would guess that if it has lasted this long that you would be o.k. into the spring. By no means should you risk trying to get through next winter with it. I have seen too many disasters in my career.
Re: Weil-McLain EG-40 intermittent startup with ongoing start signal from thermostat
There's a little switch on the vent damper motor (auto/manual). The next time the damper is open and the burners fire, switch it to manual and see if the issue dissappears. If it does, you can leave it that way. I think it'll cost a 2% drop in efficiency.

Re: System 2000, nearly double the cost of Weil McLain, is it worth it?
I'll keep it simple guys, 48 years in the field, installation and 24/7/365 service. We installed EKs for 15 years, over 1000, maybe 2000. 100% customer satisfaction. When you deal with oil customers on a service contract you hear it if ANYTHING is wrong. Even replacements of fairly modern low mass boilers (WM468, Peerless ect03,4, et al), have had substantial fuel savings. Tech support has always been excellent, though rarely needed. These are the facts men.
Re: System 2000, nearly double the cost of Weil McLain, is it worth it?
The only issue that I see here is the entity that quoted a ridiculous EK price. My experience has shown that customers recoup the price differential, depending on circumstances of course, in 2 to 4 years. After that is money in the bank and a good selling point for a future home buyer.
Re: Lochinvar WB80 not lighting, many new parts already. SOLVED
I prefer to Test and not Guess. Every time you change a part you could be introducing a new and/or different defect into the situation. This can be expensive, frustrating and time consuming.
Its funny how the data sheets don't provide useful data. Coil V1 and V2 what is their resistance ? A useful tidbit for a field tech.
Going by the current draw I would suspect the resistance of each coil V1 or V2 to be in the 100 Ohm ballpark, V1 (pins 1, 2) and then V2 (pins 4, 5). I would measure their resistance first. Also Measure each of the 4 pins to the metal body of the gas valve, it should be infinite, open (OL, on some meters) like when the probes are not in contact with each other or anything else that has resistance.
Then take the circuit board out of the plastic case and plug it into the gas valve making sure it can't short against anything metal. This may provide easy access to test the voltage right at the Gas valve connector pins or at the other side of the board where the connector is soldered to the circuit board. Then with everything connected up measure the DC voltage across V1 (pins 1, 2) and then V2 (pins 4, 5) during an ignition attempt. As mattmia2 stated it should be a DC voltage, in a similar scenario my meter reads about 15 % lower measuring Pulsating DC or Vrac than the actual AC voltage on the wiring harness side of the little circuit board.

Re: One year old Williamson-Thermoflo heat exchanger failure
I went back to this furnace today. First thing I did was measure TESP with just the fan running. I measured 0.53". It was better than I expected. Pressure drop through the evaporator coil was low.
Then I went to measure temperature rise. The burner is equipped with a Carlin 70200 primary control and I noticed the burner was running for 5 minutes before the fan and limit control brought the blower on! So I drilled a hole in the jacket to measure temperature next to the fan and limit helix . The "fan on" setting on the fan and limit control was factory set for 110⁰. The blower didn't come on until the limit control was at 150⁰ and my thermometer was measuring 170⁰. After 13 minutes of operation my temperature rise was 63⁰.,
At this point I was satisfied that a defective fan and limit control was the reason for the heat exchanger failure. I repeated my test and recorded a video of the malfunction. I called the Williamson-Thermoflo tech support agent and informed him of my findings.
He continued to insist that the chimney was the problem and on top of that he said he never, ever saw a heat exchanger fail where the cracks are in my picture. He said he would need to see my a piece of paper go through the cracks or pictures of open holes before he could confirm that the heat exchanger has failed. He said the fan and limit control malfunction could not cause that. I insisted that my combustion analysis and pictures prove the heat exchanger failed.
Fortunately the good folks at the warranty department at Williamson-Thermoflo have provided my company a written confirmation that the warranty claim has been approved at this point.
Despite the way they insisted that a "cold chimney" was the culprit the installation instructions did not state that the furnace can't be installed on an exterior masonry chimney.
Re: System 2000, nearly double the cost of Weil McLain, is it worth it?
@riny, thank you for your comments. Please PM me or call us at 908 735-2066 to connect you with your territory manager to facilitate work with your contractor; Energy Kinetics should not be 2X the cost of a WM.
@jesmed1, take a look at the Department of Energy lab studies here which analyses actual field performance with details as to why savings are much greater that shown with AFUE alone for Energy Kinetics low mass boilers with thermal purge. Field tests from the National Oilheat Research alliance showed average savings of 25% when upgrading older systems, with some savings exceeding 40%.
We typically receive very high marks for customer service and contractor support, so I'm not sure where @Long Beach Ed is coming from (thank you for your post @HVACNUT !).
Sorry for the short reply, I only had a minute.
Best,
Roger
