Re: The case of the backward flow, this Friday's case
I wasn't familiar with that burnham model so looked it up. In case anyone else isn't familiar with the internals of that unit here's a snapshot

Re: Munchkin updated
So far so good ,good turn down ,pump built in ,easy access to combustion chamber for cleaning but truth is time will tell . I ve done all in my powers to make sure everything is correct up to,and including water quality so time will tell .
As for installing each unit has it’s learning curve and ever installer finds his way . Personally for mod con I like a water tube over a fire tube but that’s me . I like the idea of my heat exchanger having its own pump for circulation and to ensure enough velocity to flush and scour debrie .
All in all for the money there a good unit no better no worse if properly installed ,programmed and set up as most units in its price range . The 10 to 1 turndown is also nice . Most likely when my munchkin kicks it I ll put in a elu . Thanks for the kind words
Peace and good luck clammy

Re: Wood-fired Steam Heating
I hate to sound fanatical (well, I sometimes am...) but... any solid fuel fired boiler, steam or hot water, should, in my humble opinion, have two safeties on it in addition to the usual ones. First, a thermal link on the dampers so that if the unit overheats the thermal link melts and the dampers close completely. Second, if is steam, if it is at all possible a gravity water supply sufficient to feed the boiler for the duration of the largest load with no condensate return (as well as a Hartford Loop of course).
Consider. With a gas or oil fired boiler, if the electrical supply fails or is cut off by one of the safeties, the boiler stops -- right now. With solid fuel... it just keeps right on going.
But that's just me.

Taco zone valve
I have 2 zones. The upstairs is not getting any heat while downstairs is fine. Replaced the upper thermostat. The valve control shows 2 yellow lights indicating calls for heat.zone 1 red light is on while furnace heats downstairs.No red light for zone 2. The zone 2 baseboard water line is not warm. T h e valve units power supply is open and the unit is hot to touch. Could the power supply unit be burnt out and stuck open? Any other suggestions as to why zone 2 isn't heating ?

Re: Any hope for my National Heat Extractor 100 series oil boiler?
Yeah, @Steamhead I used to use the Beckett SR and liked that burner.
Carlin also had flame retention with 1725 rpm 175 FR and others.
But not sure if they used the same chassis with 3450 which was your point.
@billtwocase Ah the old soot makers, Petro was one of the best at that and the odd motor with the two diameter step shaft. The old stuff was dependable, you could drop it off a cliff and it would still run.
When the 100crd and the AF came out (about 1970?) we thought we had died and gone to heaven. Some complained about noise, lining the chamber helped and also standardized parts, the 100crd and AF used mostly the same parts.

Re: Attic Radiator Sloshing/Spitting Water
That radiator or the horizontal pipe that may feed it is holding water, lifting the whole thing up a 1/2 or more. Just be very gentle you don't want to break anything.

I forgot about that.SlamDunk said:After experencing Canadian smoke from forest fires 1000 miles North of me all last summer, I'm surprised there are any trees left.

Re: Prestige Solo 110 boiler. Is there a way to switch modulation off and on?
Does it have a boost function that you could set aggressively

@mattmia2
Actually, they are piped the way they should be piped. If each boiler connects to the primary separately, they will get different return temperatures and if running both boilers one boiler will affect the other boilers temp.
Most manufacturers with multiple boilers will show them that way. You want the boilers to get the same return temp and the supply temps from each should mix before it goes into the primary loop.

Re: Door blower test came back 2000 below 4k sq ft - ERV recommended
They typically get tied into the HVAC distribution system.
Usually an interlock to run the fan on an AE.
You could do bath exhaust on timers.
