Triple solenoid

@ April 17, 2014 1:09 PM in losing heat

might be what makes the Cold (70) setting work on some of the newer washers?  

I just ordered half a dozen

@ April 17, 2014 12:08 PM in Loctite 55

at that price and for under $11 in shipping, I figured what the heck...

Kiwi hydronics

@ April 17, 2014 11:46 AM in Modifications to Hydronic System

now I recall your earlier posts.  15ºC is just fine for the boiler, but I would still do a heat loss calculation before you assume the boiler does not need a buffer tank.

Cv and valve sizing

@ April 16, 2014 10:09 AM in Modifications to Hydronic System

Optimal sizing will deliver full valve authority, which is critical in mixing applications.  We usually aim for a pressure drop of about 4 PSI across the valve at full flow (translation:  GPM = 2 x Cv.)

A few more basic questions: Why are you assuming 15ºF ∆T on the boiler?  What is the design day heat loss for the structure?  Does the boiler have sufficient water volume without adding a buffer tank?

It would be interesting to know

if the connected EDR is actually 407 or 427.

Can you post a picture

@ April 14, 2014 12:21 PM in Boiler pressure rising

of the boiler and nearby fittings, valves, pumps, etc?

Tap on the expansion tank with a screwdriver handle.  What kind of sound does it make?

Do you have the TriMax Control Supplement?

@ April 14, 2014 11:23 AM in Two Circs - TT Prestige Excellence

Look at P.10 for details on the pump settings.

Do you have a tankless coil or an indirect?

@ April 14, 2014 11:12 AM in Boiler pressure rising

Have you checked the expansion tank?

I was thinking tubing

with a trailer-mounted boiler, perhaps a rental. On a hot day.

http://www.jmesales.com/ sells a lot of useful stuff, but 20k gallons is a lot of mass.

Those two terminals

above the transformer have 24VAC on them.

Ran across this the other day

@ April 12, 2014 3:42 PM in What do you think of when somebody says Hydronics?

and thought it was quite well done http://modernfarmer.com/2014/03/real-talk-milk/

PEX-A is a superior product

@ April 12, 2014 3:40 PM in who is this Mr Pex guy

and can be used with any fitting system which works with PEX-B.  Try it -- I suspect you'll appreciate the increased flexibility.

Nice work

@ April 12, 2014 2:47 PM in What do you think of when somebody says Hydronics?

always good when we can turn what was once waste into useful work.

Government intervention is a big part of what got us in the mess we're in with our farming operations.  Like so many other things, retail milk prices do not even come close to reflecting the real costs involved.

flanges come with gaskets (not to mention lots of configurations and cool options.)

is PEX-A, good stuff, and a good company to deal with.  We use it with Uponor F1960 EP fittings.

@ April 10, 2014 10:40 AM in Is my steam boiler way oversized?

is in West Virginia.  Don't recall any pros hailing from those parts posting here, but I haven't been around all that long.

"Nearest dealer" is pretty much a crapshoot.  Better to find someone with proper conversion burner training, hopefully with some steam background.  Tim McElwain might have someone he can refer.

The heat loss calculation

@ April 10, 2014 10:24 AM in Recirc Line

should probably be mandatory, but the devil would definitely be in the details as far as implementation.  This probably deserves its own post in the Codes forum.
 

One-haded reciprocating saw

@ April 10, 2014 10:18 AM in Tub strainer removal

had to go look that one up https://www.ridgid.com/us/en/one-handed-recip-saw  Kind of like a Hackzall with more grunt.  I like it.

You might

@ April 9, 2014 12:37 PM in Is my steam boiler way oversized?

be able to remove some sections when the repipe is being done, and end up with a V-905 when you're done.

Installing a smaller oil burner will cost almost as much as a NG conversion burner would.

Larger boxes

@ April 9, 2014 11:45 AM in Controls cabinet

Don't seem to come at the nice prices, and the shipping can get to be rather pricey as well.  Used/surplus maybe?

What size?

@ April 8, 2014 10:49 PM in Controls cabinet

and what NEMA rating?

Simpler

@ April 8, 2014 10:43 PM in Is my steam boiler way oversized?

V908 is rated for 2,888 square feet of EDR.  You have 1,433.  Your boiler is twice the size it needs to be.
