Re: Hydronic heat not as efficient as forced air ?
I would like to add, the OP is assuming the hydronic system was properly designed and set up.
What are your outdoor reset settings? Have you tuned them? Combi boilers most times are a compromise. To size for DHW load most times they are way oversized for the heating load, which will impact efficiency.
We would need a lot more information to even discuss this topic with respect to your system.

Re: New Crown Steam Boiler
Gentlemen I did not do this install someone else did and they do a very piss poor job. All incorrect as others have mentioned
Re: Spirovent VS Amtrol air purger ?
Did you replace the air separator and not follow the advice (from the other thread) to move the expansion tank to the other side of the circulator while you where at it?
Your problem is not and never has been the type of separator. If you pump away from the expansion tank your air problems will be solved. The separator does not have to move, just move the tank

Re: Stand alone whole house humidifier?
Poke holes in your rad vents. 
got hosed yesterday
So we did a new boiler and the puker was dripping, I'm like 'dang, that's odd'. I replaced the exp tank and all is good. At the end of the day (couple hours later) I take the bad tank up the stairwell, need to return the darn thing. It was a true comedy scene, I had the bad Extrol in one arm and a small/medium load of miscellaneous tools and wares in the other. Half way up the stairs the bad tank starts shooting water, like, it's shooting out pretty darn good.
I need a thumb to plug the aperture. I can't just drop what I have in my left arm; that would be a problem. My brain races and I kind wiggle my little hips and scooch the tank so I can get a thumb on the top of the bad tank. It kinda works. It's still spritzing though becasue my muscle group wasn't expecting this bout of balance. One wrong move and the tank pops out of my right arm and bounces away. The homeowners are 20 feet away, sitting in their chairs watching some political tv show. Mid terms were hot this year. I think they are the 'other party' based on the channel.
I get to the top of the stairs and try my best to unload the left arm. The nice lady clearly sees my struggling and comes and asks if I'm alright, and if I got hurt. I say I'm fine, but I have to explain what happened. After all, her nice husband is a retied mech engineer.
It was all good. she was cool, the hubby was chill. We ended the day chatting; he was telling me about his working days as a lead guy at a tampon factory. I learned more about tampons in 5 minutes that i knew the previous 52 years.
Today was more normal.

Re: So how old is this water boiler?
Probably about as old as your great grand daddy. And about as efficient as a fire in a burn barrel.
And that's asbestos covering it.

Re: Help with sizing new mod con boiler
If you're doing fine with a 94k btu boiler and a 41 gal indirect, why do yo think an 80k + a 50 gal won't be enough? It's your $$, and a larger tank won't hurt the system at all, but I can assure you the 80k + a 50 gal is more than sufficient.
Code requires an ASME 1070 tempering valve to be installed. Do like Rich said and set the indirect stat to 140*+ and the tempering valve to 120* and you'll get about 15% more capacity and kill Legionella at the same time.
