Nice clean piping work.

Re: H B Smith model 19he-04 value
Had the old bus station in Hartford, CT. They had steam and renovated tore it all out. Put in Gas fired roof tops with ac.
The building walls were brick construction and were exposed inside. They changed it into offices during the reno. What a joke.
Yeah you could get the air temp to 70 or above but everyone that worked their complained. Dan talks about "cold 70" in one of his books. The walls were cold and it was awful.
That's what happens when you rip out perimeter heat with a large heat loss at the walls or a lot of windows. Ducted overhead heat is always a problem unless you add perimeter around the room. With a VAV system they always complain about cold air blowing on them even if its warm the velocity make it feel cold.
Yeah it was designed by an engineer
Re: Replacing large steel pipes going to/from hot water boiler to cast iron radiators with PEX
@Brandon_MN I did pretty much what you are looking at not too long ago. Kept all the old pipes in the walls to avoid any interior work. In the basement I removed the main horizontal pipes and connected right to the eblow on the risers going up. Some of the risers had more than one rad, those got 5/8" feed, the rest 1/2". All pipe home run to two manifolds in the utility room. Ran all the new pipes through the joists so I now have a completely flat ceiling.
It does look a bit wrong to see 5/8" pex connected to 1 1/2" black pipe. The funny part is that the system works way better than it ever did before. Some of the rads that were far on the old gravity main would never get enough heat, with the new setup I can dial in the flow to these and get nice even heat everywhere.
Best part is no more pipes that I can bang my head into.
Undoing some of the old pipe was not fun, did break a pipe wrench with a 6' cheater bar but got all the pipes out of the fittings.

Re: York furnace slow fan speed
is y from the t-stat connected to the control board(or is it a communicating t-stat)? is it an ecm motor or is the speed set with tap connections on the control board?

Re: Have you cleaned the piping system for a converted gravity hot water space heating system?
Unless you do a total re-pipe let sleeping dogs lie. You stir up all that stuff and you will never get it out anyhow and it will cause more problems.
use a strainer and a dirt mag a big one and leave it as is
Re: Basement Heatloss - Boston
I'm with @hot_rod on this one. What have been your experiences in the past? say last winter was very cold in January…. That usually happens every year but we can just look at last year. What was the basement temperature for most of the January days?
- Reply A: The basement was the correct temperature. answer: It ain't broke. Don't fix it
- Reply B: the basement was warmer than i would like. Answer: Add some insulation to the pipes
- Reply C: The basement was cooler than I would like. Answer: remove som insulation from the main pipe
Re: backflow at funeral home
I ran into a similar situation. The funeral home only did 5-6 funerals per year. The water department told him he needed an RPZ when we gave him the quote, I thought he was going to need his own services. He tried to fight city hall. He didn't win they shut off the water to his building that was also his house. His wife didn't love that. He was calling us thieves one minute now he's your best friend and wants it installed yesterday.

Re: H B Smith model 19he-04 value
Are heat pumps that efficient now? using electric to suck the heat out of 5°F outside air and compress it to heat a building that used to be heated by steam does not sound like anyone who is in the decision making process was doing the due diligence required to keep the occupants comfortable this winter.
I am reminded of the Rabbi that called me from Ventnor City, NJ who purchased an old church building and removed all the steam pipes and the boiler from the church basement. Now the Temple has 10 huge radiators behind decorative radiator covers that match the interior of the building. They have two 5-ton mini-split heat pumps that cool the building just fine (maybe) but all the congregation wear overcoats in the winter.
His query was "How much will it cost to reconnect the 10 radiators to a new steam boiler?"
I asked him what kind of budget he had for the project? When he replied with a number, I said I might be able to connect one radiator for that much money. A boiler big enough for all ten radiators would cost much more and the piping even more. You now have a worthless building to sell to someone for summer time only use… maybe!
