Outdoor Boiler install?

15 posts in this topic

I thought I'd ask a question on the Outdoor Boiler install I will be doing soon. For you guys that have an Outdoor boiler, or knowledge in this area, what did you use for your underground pex tubing? I can purchase the insulted tubing from the dealer for $12 a foot, but that seems steep? Is there a cheaper way of doing this, or should I just do it right the first time and not take any chances?

I had an outdoor boiler installed last year. I also had the same concerns as you...but ended up going with the manufacturer's encased insulated piping. Now am glad I did. It works great. Very little heat loss from boiler to house (Also from boiler to another out builing.) yes it is a little bit more expensive, but you get what you pay for I guess. Why spend the money on a new boiler ...then cut corners on on item that is so crtical in the performance of the system?

My recommendation is go with the good piping....maybe negotiate the price with the dealer.

I don't have any specific experience, but here's a couple of thoughts.

Who is going to do the install? If it's a contractor they're going to want to get it done as quickly as possible. If you're going to do it you may be able to spend some extra time and save some money and make a difference.

A thought I had was why not dig the trench and then build a chase out of high denisty foam insulation and run the pipe through that. I also suspect that you would want to go deeper rather than shallow. The greater the difference in temperature between two items the fast the exchange of heat. So if you have it up towards the surface you're going to lose more heat. If you have it down below the frost line you'll lose less.

So, how much screwing around to you want to do? No matter how it's done it seems to me that putting down a couple inches of high density foam insualtion on top of the pipe would make a difference.

I think the foam board insulation is only rated to 150 degrees? I also heard someone that used foam board insulation had issues a few years down the road.Pipe insulation doesn't have much of an R value I don't think? Otherwise I could put pipe insulation on the 1" pex and then run it in drain tile. Lots of options, but I'm unsure of which method to do? I will be doing most of the install myself.

The insulated enclosed piping I was referring to is made by/for Central Boiler. Might suggest you refer to their HSOforum for more info. I had that installed and IMO, it is very good...just a bit tough to when trying to make a radius.

Spend the extra $$ and go with the pre-fab tubing.

We used the 1" al-pex(kitec) and the preformed round foam and then stuffed that into 6" draintile. This is what Aquatherm reccomended to us. We purchased the pex and foam from them and the draintile from the save big money store.

Interesting..... A few questions for ya. What did the preformed round foam cost,what lengths did it come in, and do you know the R-value of the foam? The save big money store also has 1" pex at a save big money price!

Good question, that was 2 summers ago. You could call aquatherm. I just remember it is cheaper then the insulated pipe. Does the m store have the al-pex? I know they have the regular pex but make sure the pipe the pipe has an oxygen barrier. That is the reason for the al-pex(kitec) pipe. I will try and look back and see what the cost was.

What's the need for the oxygen barrier pex? I tried to get a hold of Aqua therm, but they close at 4:00 p.m.

It has to do with the antifreeze in the system and if the pipe does not have an oxygen barrier the oxygen can absorb through the pipe into the antifreeze and ruin it. What kind of boiler are you installing? Do you have in floor heat or heat exchanger in forced air furnace?

It's a Central Boiler 5036 and I'll be getting a heat exchanger installed for forced air heat. I don't plan on using anti-freeze for the system.

The antifreeze also helps to protect the system, not just from freezing. I like it, that way when we go away for a weekend we can let the fire go out and not worry about it freezing. I bought all our antifreeze at Mnarnds. I looked at mine reciepts and the 6" round opreformed foam for the pex was $2.00 a foot and the 1" al-pex was a $1.35 per foot. This was from aquatherm in the summer of 2007. Good luck with your install.

Don't have anti-freeze in mine but have people available to come over and pitch in some wood when/if I'm gone. If I didn't have that, I'd probably run the anti-freeze. Protcting the system is done with the corrosion inhibitor. That you'll add into the water then test the water. Just follow the instruction in the test kit. Real simple.

    • We actually just watched the first season of this show on Netflix finally. We loved it! We binge watched it and it only took us a little over a week to watch the entire season. We actually just finished watching Breaking Bad this winter and this was the next show we started. Season 2 should be out on Netflix within the next month or so I should think?
    • A lot of great ideas , seems liquid smoke is a fav, lipton is a good thought too. Great looking burglars fellas, and that bacon wrapped meatloaf looks mouth watering thirdeye.  I went back through my pics looking for the open pit burgers but all I found were steaks, but holy moly I must eat burglars a lot Cuz there's a bunch. Think next time I'll mix it up and see if anyone notices, thanks gents and keep the pics coming!!
    •   I agree. I wasn't exactly counting down to the midseason premiere, either, but it was a good, solid episode. I also really liked the clothes line scene--best action sequence in quite some time. I was impressed with the start overall and it's nice to see some sense of urgency and not just Rick moping around licking wounds.   Last night was...okay. Nothing stood out as bad, but it wasn't mind-blowingly good either. I am still reserving judgment for how this season ends, but half two is off to a pretty good start. I just hope they don't go off on a side character episode and kill the momentum they have going...
    • I for got, we added wild rice too!!  and only hand harvested too, I think it makes a huge difference in taste.
    •   Think his staff just wanted a break ........
    • What is your prediction on how soon after ice out that people will be out on Mille Lacs.  I am guessing within a week.   
    • I just pulled the trigger and bought the Milwaukee 1/2 inch brushless fuel drill and the 6 inch K drill setup.  Tested it this past weekend.   Could not be happier. 23 holes and battery still had one bar left. This was in approximately 18-20 inches of good ice. 5.0 battery. 
    • the one mentioned here, they have gone up to $399.99 but they still had free shipping and no has them around here.  they were very pleasant to talk to and get info.
    • One big boy just left Elite and went back to Mathews. Elite is a good shooting bow. 
    •     I'm sure God approves. After all, he's not in charge down here anyway...
