Plumbing / Layout at back of furnace
« on: August 29, 2019, 08:17:50 AM »
I have a Polar G2 and I am just getting ready to install the pump at the back of the furnace. I went with a Grundfos 26-99(thanks for the input on my previous post). While I'm waiting for the pump to arrive I'm thinking of how to layout the install in the furnace.
I have LogStor pipe running up through the pad. What I'm wondering is how much should I leave sticking up and how far back should I strip the insulation. Also, for the flange and pump, should I keep the pump as close as possible to the manifold of the furnace?
I have tried looking around for some pics to give me some ideas but can't seem to find any.
Any recommendations would be appreciated.
Thanks

Okay will do. Just trying to figure out how long to leave the logstor inside the furnace for pump connections. Would make it easier to cut the insulation off before the furnace is set on the pad. Might get a better idea of what needs to take place once the pump gets here and I can see it and the flanges. Like I said before, i am new to this so i can't get a picture in my mind what it should look like and i have searched around for some pictures but can't seem to find any.

Thanks very much...believe it or not, that makes sense to me:)
I was still leaning toward the 26-99 but after reading your post, I am sure now. I agree, why play with trying to save a couple of hundred bucks and risk the investment on the furnace not working correctly. Then I would have to purchase the 26-99 later and eat the price of the smaller pump.
Thanks for the great explanation.
I feel more confident now.

There are a lot of places with BTU numbers. The one that looks like what you are asking about says Heating Load: 44616 Btuh
Other s that I see:
Heating input 60000 Btuh Sensible cooling 12600 Btuh
Heating output 56400 Btuh Latent cooling 5400 Btuh
Actual air flow 1075 cfm Actual air flow 600 cfm
Air flow factor 0.024 cfm/Btuh Air flow factor 0.038 cfm/Btuh
Thanks

I actually found a fairly good price on the 26-99 flanges included for $380 CAD shipped, thats the best I found so far.I will likely go with that and see what happens. Now I have to figure how to connect the pumps at the back.
I will look around and see if anyone has any pictures of what they did.
Thanks again everyone .

Sorry I am new to this. I don't know what you are asking for with the heat loss and HX ?
I am from ON Canada. I can't find those pumps for $150 here. If I order from the US I get nailed big time for duty and brokerage fees. Sometimes more than the price of what I buy. The cheapest I can find here is $298 USD or $398 CAD for the 26-99.
I was offered a Chinese knock off of the 26-99 for $275 but I think I will steer clear of those.
I did plumb in a fill valve in the basement, figured much easier then trying to fill outside in the winter.

I wouldn't imagine he would be willing to take it back if its too small. He is a few hours away from me and i have it shipped here so there is that too.
The loop to the garage is about 50 feet of LogStor to the garage slightly uphill. Then copper up to the ceiling where the air exchanger will hang, about 15 feet to ceiling. Don't think the 15-58 has enough head to push it that far ?

The Polar G2 does have a recirculation pump..
I am a little afraid of the 15-58 running on high speed and not doing what I need. At that point I have no further to go other then get a bigger pump. I would try the 15-58 if it would work for my garage when I get it insulated but, it has more head than the house so, it won't work there.
The 15-58 is half the cost but I could end up eating it and buying the bigger 26-99 anyway ?
I don't know...

Plumbing / Pump Size Confusion
« on: August 21, 2019, 07:49:33 AM »
Hi Everyone
I am to the point of choosing the circulation pump for my Polar G2 furnace. I have mentioned pump sizes here before and it was suggested that I use the Grundfos UPS 26-99. I thought I was all set to go until I went to order the pump from my supplier. He said he had them in stock but asked why such a big pump. I told him my setup and he said he though the a UPS 15-58 would be all I needed and at a considerable less cost. Now I am really confused.
My boiler is about 80 feet from the house, the run is LogStor 1" pipe to the house. Once inside I switch to 1" copper, which goes from the LogStor up the wall about 8 feet to the ceiling. Then the copper goes across the ceiling about 16 feet to a plate exchanger for DHW then about 8 feet to the water to air exchanger in the furnace then back to the Logstor.
I have a heat loss done when I built the house last year but not sure how to use that information to do the correct calculations to figure out what pump size I need. I don't want to go under sized or over sized if possible.
Any help or suggestions would really be appreciated .

Plumbing / Re: Insulation for 1 inch copper
« on: April 05, 2019, 06:22:40 AM »
Thanks everyone for the input. I will wait and see if I really need it before putting it on. But good to know the foam stuff is okay to use if I do need some. I was just thinking about putting it on the pipe where it goes to the first exchanger, the plate for DHW, but maybe don't need it. The pipes are in a heated basement in a furnace room and I really kind of like the look of the copper. I hope to get it done in the next day or two, if I don't get called out. Will post a picture when done..

Plumbing / Insulation for 1 inch copper
« on: April 04, 2019, 02:59:24 PM »
I am running the copper lines in the basement and wondering what is recommended to insulate the one inch copper lines inside the house ? I see the foam based stuff available at Home Depot but not sure whether it would tolerate the high temperatures or not ? I have also seen fiberglass stuff but it seems really expensive..
Any recommendations ?

Well, I have a call into the LogStor rep for Ontario. See what he says when he gets back to me. If I can't get the ones slimjim mentioned I will be on the hunt for the best alternative.

« on: March 31, 2019, 08:15:12 AM »Those ideas may work BUT if you want to use the actual Logstor fittings, this is what they look like.Slimjim...I haven't seen anything like that in my searches. I don't quite follow how it's installed ? I have had a look on-line and can't find anything like that, around here anyway. Strange that the guy I got the pipe from doesn't list them.. they look like they would work awesome and likely pricey too.
The outer collar is swelled but the bolt and plate to fit over the Logstor, once the pipe and collar are together the 1/2 inch bolt and plate are discarded and the 10 mm bolt nut and washer are used to tighten the collar around the pipe.
Maybe only available in the US ?

Okay great thanks...I also checked with the supplier again and he said "I would use 1M x 1 barb insert brass with T-bolt clamps" so I assume that's what he originally sent me.
