Re: Natural gas price spikes in MA
can we avoid the politics? Doesn’t seem relevant to the discussion. Gas infrastructure costs are increasing and not partisan to me
Re: strong smell after boiler install
You never know. Hard to imagine it's actually the dope. Looks like a regular grey pro dope. Probably the best smelling dope out there. As usual, I could be mistaken
Re: Advice on hydronic radiant heat partial install
To the extent the space is already being heated, it is being heated by the geothermal. So taking hot water from that heat pump will not increase the overall heating load.
Re: Steam Vent long ago
Simple. Back then, the buildings likely would have had coal-fired boilers. These boilers were "banked" at night so the fires would not go out, then fired in the early morning, and stayed hot all day. So the steam only came up once a day. Even radiators far away from the boiler would stay hot once the steam reached them.
This also explains why many vintage systems did not have main vents. So what if that furthest apartment took an hour to get heat? Once the rads got hot, they stayed hot all day.
Re: Question about B-vent termination and CO
building a chase and sealing it to a brick building will be a bit of a task
A power vent out the side might be an option if you can get clearances from openings and windows

Re: Periodic fail
I agree with all of the above, and it's all needed work, but… I have run into that problem and even after all that found that the primary control may be the problem. I do like the Carlin 70200S…
Re: New Backflow Preventer Failed
P2902.5.1 Connections to Boilers
Where chemicals will not be introduced into a boiler, the potable water supply to the boiler shall be protected from the boiler by a backflow preventer with an intermediate atmospheric vent complying with ASSE 1012 or CSA B64.3. Where chemicals will be introduced into a boiler, the potable water supply to the boiler shall be protected from the boiler by an air gap or a reduced pressure principle backflow prevention assembly complying with ASSE 1013, CSA B64.4 or AWWA C511.

Re: Help with fuel oil boiler!
This is exactly why we use combustion test equipment on a service call.
