Re: Is this Air Admittance Valve Installed Correctly?
In my state there is nothing legal about that installation. Air admittance valves are not allowed unless with a variance from the plumbing board.
No slip joints after the trap.

Re: Is this Air Admittance Valve Installed Correctly?
I don' know what type of soil piping you have in your house, ABS, PVC, Cast Iron, Copper, etc. You have to determine where the blockage is. If women use the sink, I have found on many occasions that hair balls build up before the trap and slow drainage.
Re: Dunham 9a
As always with vapour systems like this, get the pressure under control! You want a maximum boiler pressure — cutout — of 8 ounces, and 6 is probably better.
I'd almost be surprised if a buried wet return ("condensate line") wasn't leaking. Perhaps a lot. Replace it.
I doubt the end of line main vent belongs there. It might — but it would be more normal for there to be a crossover trap there, with paired drips to the wet return. Since it's there, it will do no harm particularly — if you keep the boiler pressure down. Otherwise it can and will defeat the operation of the return trap.
Water spitting out of it, though — many possible causes. But start with the pressure.
Re: Outdoor Reset on Lochinvar vs. Taco
Is it a Combi? Doesn’t look to be. Those have an always hot setting that causes short cycles
the Lochinvar control has a couple parameters in the control to address short cycling
First limit the boiler output to match the actual heat load, do you have that number?
You could guesstimate based on the number of loops you have, that is what limits how much heat you can move into the space.
The anti cycling feature puts a time limit on the repeat cycles
A read through the manual explains how to set these functions

Re: Turning off heat while not home
Don't set back when your heat pump has electric resistance heaters for the second stage.
To better understand how a heat pump works in numbers (hypothetical)
Electric heater with the resistance heat coils (like the red glow in a toaster) will make 3412 BTU per kilowatt of electricity,
if one kilowatt of electricity costs 20 cents then you will get a little over 17,000 for one dollar
$1.00 = 17,000 BTU. Electric Resistance Aux Heat
If your heat pump has a COP (coefficient of performance) of 3.0 then one dollar will purchase three times as much heat from your heat pump.
$1.00 = 51,000 BTU Heat Pump Compressor Heat.
If you turn off the compressor for 6 of the 8 hours that you're at work and your house needs 51,000 BTU per hour to stay warm for those 8 hours (based on the outdoor temperature that day) you would save about 6 dollars that day. Then at 3 PM your clock thermostat turns your heat back on to be warm for you at 5 pm when you get home from work. The heat pump would need to operate for two hours non stop to maintain 64° that would cost you $2.00 for 51,000 BTUh for 2 hours. (51,000 BTU will only maintain the temperature it will not increase the temperature on that particular day)
But you want 68° when you get home, so the auxiliary heat would also operate for some of that time in order to raise the temperature up to 68°. If your 5 kW auxiliary electric resistance heat were to operate for 2 hours in order to make that home 4 degrees warmer then you will be using $5.00 per hour to get another 85,000 BTU per hour from a 5 kW auxiliary heater to increase the temperature. That would cost you an additional $10.00 for the time the electric resistance heat is operating. Add the $2.00 to the $10.00 and you get $12.00 to NOT heat your home for 8 hours.
That is more than the $8.00 you would spend on heating your home with the heat pump alone. Of course the 5KW heat may not operate the entire 2 hours of the recovery time from 3:00 to 5:00PM But even if it only operated for one and a half hours you would still pay about $7.50 for that time. If your electric resistance heat ran for only one hour during the 2 hour recovery time you would pay $5.00 for that time, then you would save about $1.00 for NOT heating your home.
For the heat pump setback to save you any real money, you need to leave it off for more than 24 hours before you get a benefit from turning it off. If you are going on vacation and you want to leave the thermostat at 55° so the pipes don't freeze, that is a good idea. no need to keep the home at 68° for a week or two. But for only 8 hours, or less, there is no savings.
As I said at the beginning, the numbers are hypothetical, but there are occasions where it may cost you more to set the thermostat back a few degrees for short time periods. I have actually seen this happen where a customer wanted to know why they were not saving $$$ by turning the thermostat down at 8:00 AM then turning it back up at 2:00 PM when the kids got home from school. Only 6 hours and 2 of those 6 were doing recovery from the lower temperature to the regular temperature. Yea I actually cost them more $$$ to not heat the house.
Re: Honeywell Aquastat L8148E1166
The assumption that you don't own or are not experienced with a soldering gun does not equate to thinking your incompetent. But building submarines doesn't necessarily mean you can solder either. He's just trying to help. We're also just assuming it's in the board. Do you have the jumper to bypass the damper? It's probably in the manilla envelope with the manual.

Re: Turning off heat while not home
Heat Pumps………………..Set them and forget them.
Steam ……………..a few degrees set back is fine but you won't notice a reduction in operating costs.

Re: Turning off heat while not home
To which I will add… it depends somewhat on what's in your home. Plants? Pets? Musical instruments (particularly pianos)? Fine furniture? Anything more than a few degrees setback and they will be uncomfortable (the living things) or irretrievably damaged (the non-living).
But you will save money on energy…
Re: Turning off heat while not home
Depends on the length of time of the temp set back and how much the temp set back is and the outdoor temp.
If you gone for a week absolutely set the temp back 10 degrees. I wouldn't go below 60 degrees. If you gone for 8 hours or less a setback is probably not worth it. When you set the temp back it is not just about air temp. The rugs, furnature, walls,floors and ceilings cool to the setback temperature and the temperature of all these items need to be raised back up to 70 degrees or whatever your normal temperature is.
With a short set back, it will take more fuel to raise the temp back up than what you will save,.
When you do a setback notice how long it takes for the system to recover.
That will give you a clue how to manage it.
Every system and building is different. There or no hard or fast rules.
