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.

    • Trump already signalling willingness to work with Democrats in order to bypass House conservatives....     http://www.nbcbayarea.com/news/national-international/Trump-Attacks-Conservative-Lawmakers-Over-Health-Bill-417117223.html?_osource=SocialFlowTwt_BAYBrand   So now we have a supposedly extreme right-leaning Republican president cozying up to Democrats?   What would Uncle Ben think?....            
    • In order to determine which direction to go with healthcare, one fundamental question must be answered.  If an American walks in to a hospital with a sick child or with some sickness themselves and has a treatable medical condition, should a provider have a right to refuse service to that person or their child based on ability to pay?  We cannot have a true free market system unless we are truly callous enough to turn poor people away at the door.  I'm not there.
    • Ice is good in some areas of main lake but bad in areas with moving water / springs. All resort / outfitter access's are closed to vehicles but some are open to four-wheelers. side by sides, and snowmobiles including Morris Point, Long Point, Dales's and Arnesen's, which still has fish houses available as well.  As always, use a resort or outfitter road for safety as they are monitored daily.  Walleye bite has been good with many keepers among smaller fish. Fish are aggressive and having a flasher is helpful.  Jigging spoon tipped with minnow head or tail and a dead stick with a plain hook or small ice jig and minnow are doing good.  Key depth  17-33 ft.  Best colors glow pink/red and gold. Tip up fishing for pike on fire.  Many flags of northern pike in back bays and reefs.
      Rainy River spring fishing is ON!  The Rainy River is open all the way to Wheeler's Point. Birchdale, Frontier, Vidas, and Timbermill landings are open to all boats. Wheeler's Point will be open in a day or so.  Walleye fishing has been excellent. Many eater walleyes so far with a few monsters. Right now a 1/2 - 3/4 ounce jig is enough to get to the bottom while tipped with 1 or 2 frozen shiners. Pink, orange and gold are hot colors. Many sturgeon being boated as well.     Up at the NW Angle, ice conditions are unstable as current areas are opening up quickly.  Travel with caution. Many resorts using airboats at this point.  Fish houses on LOW can stay on ice through March, walleyes/saugers through April 14th.  Pike and crappies open all year for LOW MN.  
    • I loved BBs post game the other nite after the canucks game,  he nailed it.  Guys got to step it up and play, outside of granny and staal, the rest look like they just started playing.  Lack luster for sure.  Im still hoping they come out and play like I know they are capable of but not looking good
