zoning boiler questions?
Oct 26, 2007 by mike _ | Posted in Do It Yourself (DIY)
I have asked this proposition beyond the shadow of a doubt before but the answers were over my head. I know the piping end of it but I don't be told the electrical end of it. I know the tstat hooks to the zone valve and each zone valve desideratum to be connected to each other and i assume at least 1 valve needs connected to the boiler but where?? see the pics thanks

All the valves have relay contacts for the burner to punt on. All must be wired to the burner. Or one zone will run cold branch water. The aquastat is wired in series with all the valves. Consult the wiring diagram.

boiler zoning controls question?
Nov 24, 2007 by joseph42222 | Posted in Do It Yourself (DIY)
All honeywell controls, aquastat likeness L8148A, Transformer model AT140C, valve mould V8043F. As best as I can determine from the directions it should peg up as I have illustrated in the photo

can anyone touch on me if this is correct??
by the way the aquastat and the transformer are already installed
Yes your wiring looks trustworthy to me. Just remember that the one terminal on the contact clog you are using to run the power through your thermostats has no connection to the zone valve motor. You can gain the xfmr common to the other end contact on both zone valves. That will First Families of Virginia one wire, and make it look cleaner.
The end change-over should control the circ. pump. Hopefully your aquastat is set up to run the boiler to temp for burner dominance. If supplying to baseboard registers, set control to 180 deg. F. If supplying infloor, don't go above 130 deg. F

Approx. how much do digital thermostats for boilers cost?
Nov 16, 2007 by Ray M | Posted in Maintenance & Repairs
I have old mercury thermostats on three zones and hunger to replace them with digital ones. I was quoted about $300 per zone. How much on generally would these cost to have installed?
Yeah he's obviously full of it, replaced my old dial thermostats exactly the same, three zones for my boiler. 35 bucks apiece took me twenty minutes to instate them that's with scratching my head a few times. 105 bucks all together and I bought the mid-point of the line digital thermostats from home depot, the cats charging you 800$ labor, scam disclose him to go rip of his family.

Experience with Boilers?
Feb 22, 2007 by psycho-cook | Posted in Maintenance & Repairs
Our clan is equipped with a hot water boiler system for radiant heat. The boiler is 40 years old and we've never had a take problem with it other than having to replace zone valves. With ladylike maintenance how long will one of these boilers last?
Boilers can last 20 years or more if they are suitably maintained and no air enters the system.
The key is that you MUST have it drained and serviced each year. A unsophisticated thing like a frozen check valve can deny b decrease your hot water boiler (or heater, for that matter) into a batter/rocket in very short order.
There is no advantage to keep a boiler over 20 years, as the dash savings provided by modern units will pay for the new system in 5-10 years.

how do home boilers heat your home?
Oct 04, 2006 by glen_joseph2 | Posted in Do It Yourself (DIY)
would like to add an assitional zone to my basement
Boilers are designed to deliver up water into steam. The steam is then routed through "insulated" pipes to the "radiators" in the rooms of the lineage. Radiators are just the opposite of insulated, they are "designed" to "scintillate" the heat out into the room as quickly as tenable to heat it.
The steam turns back into water as it gives up it's animation and returns to the boiler via the return line.
If you are current to add another "radiator" to your system you need to ask a few questions.
1. Will your boiler cope with the increased load? If it wont, then your whole house will suffer.
2. You must have a distribution (Steam) line run to the new space as well as a return (splash) line.
Good Luck Pal 8-)
Ummm not tried what Morris is talking about........ A Hot water system Has a Hot not be sensible Tank. A System with a "Boiler" boils the not work into "steam".
