Hi! A bunch of different questions here..... 1) Can anyone recommend a place to get boiler treatment chemicals in Ontario? How about places that do water testing for boilers? I'm in Midwestern Ontario (between Guelph and Owen Sound). So, pretty much anywhere in Southwestern Ontario would be okay as well (Toronto-Niagara Corridor). I have about 8-10 gallons of a product called Klenzoid from the former owner, but I want to get a really good cleaner to clean the boiler and flush all my PEX lines as I am SURE have mineral build -up. If no one knows of chemical suppliers and/or testers, perhaps you could give me the name of the products for both the pre-cleaning and treatment that you recommend (ie. on Amazon?). Between my Plumber who is doing the install and myself, we have all the chemical testing kits, so it's not "essential" that I find somebody, but I'd just like a second opinion to confirm that my testing was accurate, you know?!? (I have a guy lined up to come and test the gases & stuff as well.). The last thing I want is to screw this thing up! ;lol 2) Garn recommends building an enclosure around the boiler and insulating with fibreglass. However, I don't really want to do that this year (or ever if I don't have to!) If some heat escapes, it will be into my shop, so that's okay. So I've been contemplating different things I might be able to do to insulate it. I'll be doing a few different things together- just not necessarily these things... But I thought about putting some kind of reflective /insulating material (like the 2 layers of foil with the bubble wrap inside) but I can't use the kind with the bubble wrap) around the boiler first & securing with aluminum tape. Followed by a 2" ceramic wool blanket, again with the aluminum tape (and maybe some other kind of adhesive??) along the seams. Then, put another cover on like the first one, but this layer could probably have the bubble wrap in between. ) Someone said something about reflective insulation wouldn't help....but I'm not sure why...I mean...it's reflective the heat back in towards the boiler, and the outer layer on the last one will reflect the coolness away from the boiler, right? So if I add 2" of ceramic blanket that is rated for 3000* to that, should I have a pretty good thermal barrier? Has anyone used the high-end insulative paint? (BTW, it will be placed on 2" of high density foam underneath the entire thing as well.) Thoughts? Ideas? Feedback? Things you've tried? I can't wait to get this thing hooked up ...it was 51* in my house the other day 🥶 ...thankfully we had a few more warm days after that, but I couldn't get it above 58* so I broke down and bought two oil filled rad heaters. But my house is pretty open...and after 4 days of running them at full tilt, they've only managed to raise the temp 2* in the kitchen/living room area and in my bedroom -with the door closed. 20cm of sNOOOOw coming Sunday and -5C....so I am dreading it!! Ordering the new firebricks today, and perhaps the ceramic blanket. Got all the new stove pipes. Just waiting on replacement gaskets and a few other parts I ordered and the only other thing left to get is the chemical cleaner! So thank you to anyone who can answer any of these questions and point me in the right direction! I appreciate your help and feedback! Patti😊
 
Hi there. A couple things. First of all, as for using a chemical cleaner on the boiler – I assume you’re talking about inside the boiler causes me some concern. I would talk to Martin Lunde before I did that. Honestly, if you feel you need to clean it, get in there with a wire brush and just brush any loose debris off. Once you fill it, make sure you have installed a filter loop and just plan on changing the filter cartridge a couple times early on. I have learned the hard way that you need to be very nice to the steel in those boilers

As far as insulation goes, my boiler has 6 inches of foil backed fiberglass insulation all around with the seams taped. My boiler is in its own separate room off my shop and it gets quite hot in there – like 90°. I keep the door into my shop cracked open, and that keeps my shop, 70° on the coldest days. All that to say, if you don’t have make a separate room for your boiler, your shop is going to be very hot. Of course that does depend on how well insulated your shop is. I have our 45 in the Wallsh in our 70 in the ceiling but uninsulated slab. Also, make sure you insulate all your exposed plumbing or you’ll lose a lot of heat that way

Hi Mynx! Thanks for your reply. The Garn manual actually lists specific pre-cleaner and treatment solutions- but they’ve gone out of business. Apparently you need to pre-clean - has something to do with Nitrates and Nitrites, and it does something to the metal that stops one of those from corroding the metal. (That’s a ‘rough’ explanation😁- I don’t have the manuals here at the moment). It’s not really the boiler itself that I’m overly concerned about because the former owner cleaned and treated it and used the filters. What I’m MORE concerned with to be honest, is my pex tubing going to the house, and the pipes over there. I have super hard water, and it was either the previous boiler or the water itself, but it turned some clear tubing in the system completely brown. (My ‘all-knowing friend’ refused to listen to me and wouldn’t put the boiler treatment in 🤦‍♀️). This time I am making SURE every single thing in the manual is DONE exactly how it says to be done.
As for the insulation…I’m not really sure to be honest. Lots of fibreglass in the attic. Walls…I’m not too sure about - not much I don’t think. It’s a well constructed Fleming steel building. My Tarm boiler had most of the pipes covered and the shop was comfortable enough to work in a light jacket. It definitely needs insulation on the garage doors, new windows, caulking etc though.
You have 6” of foil-backed fibreglass- so what kind of R-value would that be? Is it separate batts put together or one 6” thick batt? If your room gets that hot, does that mean that the fibreglass isn’t really insulating it? And/or the foil isn’t adequately reflective heat back inwards and cool air outwards? I think I am confusing thermal properties and what different materials do. But I’m thinking in terms of a welding blanket - it reflects the heat back towards the source I think. 🤷‍♀️ I believe that is what the ceramic coated wool does as well. To ME, I think reflecting heat back inwards and/or insulating to keep the boiler as hot as possible is the same thing??!? 🤷‍♀️🤷‍♀️ But I’m getting the impression from some sources that it’s not- so I’m getting confused!! 🤪 All I am concerned with is keeping the boiler water as hot as possible for as long as possible- I don’t care if it’s through reflection, insulation or anything else!! 😁 I think the insulating wool is sounding like a good place to start, and I’ll tape the seams with aluminum tape as well. Then I’ll decide if I want something reflective on the outside to improve the heat retention. This Garn is definitely a bit of a learning curve!! 😁 Thanks again for your input! Patti
