Re: How to calculate EDR for dummies
One of the problems with the guide at
is that it only mentions one type of tubular radiator. In fact their are two and they are greatly different. The first version of tubular radiators had thicker section, mearsuring 2.5" on center, the same as most column radiators. Then, the slenderized version came on to the market with a section dimension of 1.75" thick.

Re: Inside Heat-timer Varivalve Radiator Vents
Those Heat Timer radiator vents make pretty darned good Main Vents when you don't have a way to add a proper Gorton or Hoffman main vent. You can drill and tap thread right into the pipe. Sometimes you have to make do. Its the best use I came up with for those hissing spitting vents.
Re: Circulator replacement
Those will be tough to turn. Don't try it WITHOUT soaking them with PB Blaster, WD 40 or some penetrating petroleum based lubricant. Let them soak for many hours.

Re: How to calculate EDR for dummies
The EDR is equally needed when sizing vacuum and condensate pumps for 2 pipe systems.
Whenever I'm asked about replacement pumps or system problems, and ask what is the system's EDR, no-one yet, ever, has given me this information based on an actual survey of the radiation.
So that leaves me with having to rely on the steaming capacity of the boiler plant, or the pumping capacity of the old equipment.
And then they wonder why the new equipment doesn't work any better than the old stuff did. Doing the same thing and expecting a different result is………………

Re: Electric heat is too expensive, very high bills/useage
I would suggest hot water — hydronic — heat as well, but may I suggest using flat panel radiators rather than big cast iron ones? They are somewhat less disruptive to room arrangements, and are much less obvious.
However. There is the question of how to power them. The best solution would be a natural gas fired mod/con boiler. They are small (at least relatively speaking!) and can have direct outside venting and exhaust. Unhappily in some areas of the northeast it is no longer possible to have new natural gas hookups — and in others it is simply not available. Propane, then would be the next best be — also a mod/coon — but considerably more expensive.
Re: Expansion Tank Orientation
If you're concerned about being succinct, perhaps answering the questions you've been asked would be a step in the right direction. We're all trying to help you, but that's impossible when you don't provide the necessary information which is requested of you. Again, how did he determine that the water side was dry? Was the described pressure adjustment process followed?

Re: Indirect HW off steam- shaking circulator
This guy really likes to ignore the instruction manual. (I'm speaking of the height of the circulator). Oppositional Defiance Disorder perhaps.
How high is that port compared to the normal water line? It seems very high.
Re: System 2000 sudden issue
with the digital manager with the red dashes if the return sensor fails you should get an error 100 on the manager which puts it into bypass mode. The circulator will run constantly and the boiler will maintain the high limit temperature and there will be no delay in opening the zone valves. this will cause the boiler to run at a higher temperature but will allow the system to provide heat and hot water. With the display manager with the LCD screen if a return sensor fails you will get an error 100 on the screen and the system will go into bypass mode for 10 minutes to try to reaquire communition with the sensor after 10 minutes the manager will switch to an error 190 classic mode which allows the manager to operate on time instead of temperature like the original classic managers. Either way the failure of a return sensor wont allow the system to lockout or prevent heat or hot water to the house. The sensors are available direct from the factory and not at local part houses
