Re: Burnham Bleeding
Thanks again Hot_Rod .The air vent is open but I will try what you suggested on cleaning it out .Other question is since the boiler is been running due to season and I feel that maybe I need to bleed more air out of this boiler ,do you have a recommended temperature that the boiler should be around before I start doing this or not ? Don't want to introduce cold water into this boiler if temperature is to high but not sure what would be in reason either .
Re: Occupation
Punch cards mostly, @ChrisJ , though I did have access to a line printer for outputs from the general circulation (climate) model I wrote. Also punched paper tape. Banks of big tape drives... I did have in later work a program I wrote for a Commodore 64 which allowed me to type in programs to the CDC 6600 control computer I was using at the time, though, and the CDC in turn controlled the Crays out in Colorado... all programming was in Fortran.
Domestic hot water load estimating
This question come up from time to time. With todays more efficient homes, the dhw load could exceed the heating load. So that needs to be taken into account.
Knowing how many gallons per day a family uses is one key. Rule of thumb loads for years have been 10- 20 gallons per person, per day. That varies based on how long you shower, fill a big tub, clothes washing, etc.
Simply putting a water meter on the supply to a water heater for a month or so could tighten up the numbers.
Lets use a family of 4 at 15 gallons per person per day
incoming water at 55°F heated to 120.
(4 X 15) (8.33) (120-55) = 32,487 btu/ day.
If you want a yearly number, subtract out days that you are not home. Water heater in vacation mode
(32,487) (335days) = 10,883,145, call it 10.9 MMBtu/ year
Next is the cost of the energy.
Electricity at .10Kwhr 96% efficiency (4% jacket loss)
(10.9MMbtu/yr) ($30.52) = $332.66 per year!
So you often hear estimates of 3- 400 dollars per year for average family of 4 for DHW.
Your mileage may vary.
at .30/Kwhr = $998.04!
At .30/ Kwhr it could be good time to consider a HPWH

Re: Should I reuse union fittings on steam radiator?
@Intplm.I cut the nut off and then used a 24" wrench on it. Seemed to come off with ease with that method.
I have had pretty good luck removing them. You have to cut the nut off to get enough room for a small pipe wrench with a cheater pipe on it. If you plug the hole so it can't collapse it will usually come out. Of course, when they are all painted up the pipe wrench wants to slip.

Another Moline System
Just replaced the boiler on this Moline system.
The cellar was a mess covered in plastic.

The old air trap and vacuum valve were bad. We also replaced about 50’ of wet return.
