    boiler line I offer.

    This is an upgrade from a 30 year old tankless, oil boiler. The Freeport is one fine boiler. We added a Wirsbo 311 to give those glorious radiators full outdoor reset. Great clients and a thoroughly enjoyable small project!

    Curious

    as to why you used a low-loss header on a small system?

    Nice mix there: Crown-Viessmann-Wirsbo

    Best wishes,

    Alan

    The Pro Press System........

    is one of the best investments I have ever made in my business. At least 10 times faster than soldering and a virtual guaranty of no leaks, if done correctly. I have the cordless model which is the only way to go. The fittings are more expensive, but the labor savings is absolutely huge! Also, it would be smart to stock a substantial amount of fittings, although my supplier has in excess of $20K wrapped up in inventory, plus he does %5 over cost on the machines so he can get them in the field. Now, %5 isn't huge since there is little mark-up on tools, but it all helps!

    Since this home............

    is full of big cast iron rads, this is, what seems to me, to be the best way to do P/S piping for it. I wanted to be able to provide full reset. The Low Loss Header is a great place to install the boiler sensor for the Wirsbo 311. I also like controlling the domestic hot water temperature through this control. Very nicely thought out control.

    Low Loss Header

    What is its function ?
    Where do I get more info ??
  • heatboy
    heatboy Member Posts: 1,468
    It's primary function.........

    is to hydraulically seperate the boiler from the system. An improved version of primary secondary pumping. It also act as a debris settlement zone and a really cool place to put my brass plaques ;-)

    I get the low loss header from my Viessmann distibutor, but there are other places to get these. Caleffi makes a nice one.

    It's just stuff I buy from a place that specializes in all types of fastening equipment. Strut, all thread, split hangers, clics, etc..

    Flue question

    HB: I was interested in getting a 3 pass boiler like the Freeport but concerned over how far out the boiler has to sit from the wall. Any issues with comming off the rear flue vent with 2 90 elbows to get into the thimble? Ever stack a Freeport over a Horizontal Mega-store? Have you fired any with a Carlin EZ? Thanks for the info.

    3 pass designed boilers.

    Joe,

    When it comes to oil fired boilers, I offer three and only three. The Freeport by Crown, the Vitola and Vitorond by Viessmann. All three are positive pressure multi-pass designs. I won't offer any oil fired boiler that isn't positive pressure. They are inherently more efficient, quieter and easier to maintain. I haven't had an application, like Ron Jr. has, that would require anything else. If I need a standard CI sectional with a tankless (egads!), it would be the Tobago by Crown. Quality iron plus GREAT factory support. Although, I am installing a Crown gas fired Cayman with a tankless next week. Never say never, eh?

    I haven't used the Carlin yet. I usually stick with Riello, but this Freeport I opted for the Beckett. The Riello runs better, IMO.

    LLH

    The flow required simply couldnt be forced through the Freeport boiler? I dont see the point of using a low loss header in a boiler where flow is not an issue. Simple primary secondary plumbing seems much less expensive or obtrusive. You have no concerns about future leaks with the pro press fittings? Why no isolation flanges on the pumps? Is there a reason you went with a mixing valve versus the usual injection pump?

    Where you confused by the silver color ? :)

    A tankless coil ?

    Whats next staple up with no plates LOL.

    My world is shattered.

    pump bracket.

    hp,
    Nice clean job. I also have the Pro-Press tool, best investment to date.Next to my kids collage payments.

    If you don't mind me asking where do you find those pump brackets? It looks like the bolts fasten thru the flange.

    using to wire up your circs ? Pardon the term, but is it like extention cord wire?14 or 16 gauge stranded wire? kpc
  • heatboy

    So many questions.

    Yes, I could have had all of the water go through the boiler without the LLH. Or, any P/S piping for that matter. This home has tons of cast iron rads with gallons of cool efficient water in them. Flow through the boiler was not my concern. Long periods below condensing temperature is, especially running full reset. The LLH guarantees that I will have hot water mixed in to the return since I'm overpiped and overpumped on the boiler side. Also, any debris will settle out in the LLH before it gets the chance to plate the boiler.

    ProPress has been used extensively in Europe for years. Since they seem to lead the world in terms of hydronic knowledge, or at least application, I'm betting it's OK. I sense I will have more long term soldered fitting leaks than ProPress leaks.

    The panel is isolated from the boiler, radiator mains and indirect via valves. Any service needed on the panel will be simple. I love valves as much as the next guy, but it can get a little carried away.

    I choose mixing valves over VSI. My preference. Mostly, I am working with low temperature boilers and 3 way mixing valves are the best way to assure as low a return water temp as possible. VSI and condensing boilers don't, or shouldn't mix. I could have done injection, but these Belimo Valves are wonderful. We have all heard mixing valves run, but with the Belimo valves, you need to watch the indicator since they make NO noise whatsoever. I belive I have a dozen of them running and they are very impressive. I see no reason to do VSI.

    Thanks for asking.

    It's..........

    16 gauge standed SJOW cord with strain reliefs. Simple and fast to wire. BX is to hard to work with with some of the controls today. Sealtite is too big and slow, but looks nice.

    I get the pump brackets from Radiant Engineering.

    Yorkshire Fittings

    The fitting you are referring to has a ring of solder already in the fitting. It still requires the prep work, e.g., cleaning, pasting and heating with torch to make it seal. The ProPress, on the other hand , is a crimp fitting which uses an EDPM O-ring seal.

    even more questions

    So you are using the low loss header rather than tees primarily to trap sediment? Does having the boiler temperature sensor in the low loss header give accurate boiler temperature readings for the tekmar control? I'm not sure if this is how you have it set up or not. I understand that P/S is imperative when low return temperatures are possible...switching gears back and forth between condensing to cast iron;-) I can understand sticking with one method of mixing. Yeah I'm full of questions and they just keep coming to me as i sit here.....

    Check out the Dynatherm. Scotch marine boier with side flue connections only uses a 5" flue pipe that connects low on the boiler, pick the side. www.dynathermboiler.com

    Propress fittings

    So what actually prevents the fittings from blowing off. How is it held on to the pipe then. I've seen Viking fittings blow off the end of a pipe when we tried to use them as a temporary blank for a test of a section of pipe. Had to end up tomming them to stop them blowing off. Very nervracking when they suddenly blow off when you have 50-70psi in the pipe.LOL
    Sounds simalar to drain/water pipe systems but these are supported in the ground to prevent blow off.

    they were around again, George. They have been in and out of business and in so many places, it's been hard to keep up! I hear they are outside of QTown, now. I have worked on soooo many of those cast iron burners. They run much better with Riellos on them ;-)

    Spacing around Air Elim

    Rich, I generally see more distance between the air eliminator and the circ, as well as some length of straight run ahead of the air eliminator. I wonder if there is any reason for this, or if it is just a matter of style.

    VSI

    "VSI don't work on Condensing Boilers". I've heard that before.

    BUT. You tell me if I am wrong about this theory. If your Injection Pump is sized to handle the full system flow, wouldn't I be able to return the Full System Return Temperature to the boiler? I am saying that it doesn't matter.

    If your Primary Pump, the System Pump and the Injection Pumps are of the same size, then why wouldn't we be able to get the System Return Temperature all the way back to the boiler? I see no difference to a 3-Way Mixing Valve. The Injection Pump would be setup to run at 100% all of the time, unless the Boiler Supply has to be higher than the System Supply (IE. DHW generation).

    Mixing Valves are fine, don't get me wrong. But don't get stuck on a Sales Pitch. We get told so many things day in and day out. But if you sit back and think about some of those, they may or may not neccessarily always hold true. To me, I can't see why I couldn't return the full System Return to the Boiler if my Injection Pump has the same flow rate as the System Pump. Did I miss anything?
