Just one...

@ November 18, 2005 10:47 PM in Monoflo Tee's & Kickspace heaters

The diverter tee should be on the return. Don't space them too close or it will make some noise and not have much flow through the new branch.

Sex appeal

@ November 16, 2005 4:43 PM in American heating mind set?

Hey! At least boilers have a few fans. That's far better than insulation. Nobody gets excited about insulation. "Hey stranger, want to see my heatloss calcs and then take a peak behind the drywall?" hehe

It's fashion...

@ November 16, 2005 4:37 PM in NSI 3000 vs. COExperts

Everyone here raved about the the COexperts so I bought one. By the time I got it, everyone here was raving about the next one. So far the COexperts hasn't registered a thing ever. I need to take it into the garage this winter and spark up the snowblower with the door closed just to test the tester! ;-)

How is it piped?

@ November 15, 2005 9:48 PM in Monoflo Mayhem!?

Is your system piped primary-secondary with the 0011 doing the boiler loop or is it all piped as one loop?

Mr Ebel's question...

@ November 15, 2005 11:27 AM in Monoflo Mayhem!?

You still haven't answered Mr Ebel's question. Was the circulator supplying the monoflo changed? If you don't have enough flow through a monoflo system, that diverter may not be able to do its job and this would explain the lack of heat for that radiator. Also, and this sound like a stupid question, did that radiator heat up before the conversion?


@ November 10, 2005 10:23 AM in monoflow system

Home-owners opinion... If it is just that last bedroom that is cold, I would first try a different circulator. That Armstrong can't handle much head and have good flow and those ZVs aren't helping. Monoflos need good flow. I'd also look at insulation between the garage and the bedroom and see if the heat loss could be minimized there. The other thing you could possibly do is pipe directly through that last rad if it is 3/4" HWBB or do dual 3/4" paths.

What are your electric rates like?

@ November 10, 2005 10:09 AM in So, what would you suggest

If my heat loss was that low, I personally would just get an electric boiler (and WH) and simplify my life. No flue, no burner, no additional gas or oil bills, no cleaning, no explosion risk, no oil tank leak risk. I'd pay a few hundred extra a year for heat to have that for that kind of piece of mind. Thermolec is one I'd look at first...

It works for me...

@ November 9, 2005 5:07 PM in underfloor fin tube

My crawlspace that goes under roughly half the house is about 20' x 32' and had 6' sections of fin tube at each end. It has masonary block walls with a concrete floor and is well ventilated. Actually at 4'6" it could be a basement for smaller folk. Last year when redoing a laundry room above I took the fin tube out of the room and added more underneath to keep the balance. It worked out very well. Outside of the fact that the fin tubes on the end walls are in the way for insulating the perimeter walls (one of this winter's projects), there are no downsides in this particular instance. Careful how you run the tubing so that it isn't in the way for moving around and gettingbanged and also that it isn't just heating between two joists.

@ November 8, 2005 12:38 PM in GB-142 Number 5

Brian, Probably too many clicks if you ask my better half... maybe 6 or 7k on sactioned rides. I can really feel my fitness level falling every week since the season slowed down in September. Now it's home reno and pizza season until April. ;-) I believe the Aeroso tanks are made here in Mississauga. It was a joint venture with a company in Norway (they supply the heating coils). I never realized that Bradford-White bought them out 3 years ago until I went to look them up. Keep up the good work.


@ November 6, 2005 11:31 PM in GB-142 Number 5

Nice work Brian! That indirect looks local. ;-)

@ November 3, 2005 2:25 PM in HydroniCAD ready for release!

I've always found the Gadwin tool to be perfect for this. Press the hotkey and the file is saved in the format you want (GIF, JPG, BMP) at the level you want (fullscreen, application window, form window, etc.) It's priced right too (free).


@ November 1, 2005 2:11 PM in Constantin, what do you know about this?

Firedragon, no wondering required. There is a town in Northern Ontario (still) called Swastika. You wouldn't believe how close it came to being renamed Winston (after Churchill) during WWII.


@ October 28, 2005 1:40 PM in Gravity Hot Water Heating

Has anyone ever just piped one primary-secondary with a circulator for the boiler loop but leaving the heating loop as strictly gravity fed?


@ October 27, 2005 8:33 AM in Interesting system

It would be nicer if they had a smart circulator that can pump harder as the circuits close off. When all the monoflo circuit are open it only needs the single 007, but as the branch circuits start shutting down, so does the overall flow which is why they did this. I really like monoflo systems, but in this case, they really should have just piped it parallel reverse.


@ October 23, 2005 11:43 PM in Not so much heating related, but....

Try them on an sensor switch. They strobe quite nicely. ;-) Some hate the delay, but I think of it as an enhanced feature when going from dark to light and not wanting to be shocked in the process.


@ October 21, 2005 5:10 PM in Hiding pipes in wall

Could you run it nearly flush with the drywall/plaster< against the studs< along the bottom of the wall and then use a moulding to hide it?

My bad...

@ October 21, 2005 2:39 PM in new install of vitodens 200

I was looking quickly at the pix and seeing 4 copper pipes going down to them. What size is the Vito?

What a splendid looking home!

@ October 21, 2005 2:20 PM in new install of vitodens 200

Garry, you should try and shrink the size of the image that gets displayed. I'm surprised to see a conventional expansion tank, brand new even, installed with a Vito. I'm also surprised to see the indirect piped to the other side of the LLH. They sure don't build houses with those kind of refined good looks anymore.

Sort of...

@ October 21, 2005 9:24 AM in Problem with Monoflo system

You could put a valve in between A and B and then use it to adjust to the point where you have sufficent water diverted, or you could put diverter tees in at both A and B, or you could just do something crazy and make the water go an extra few turns and feet between A and B.


@ October 21, 2005 8:44 AM in Goofy Insulation Question

Mike, where's the house? We shouldn't automatically assume that it is a "northern" house. If they A/C more than heat then the vapour barrier should be on the outside.


@ October 20, 2005 9:54 AM in Russians unveil radiator monumnent

Sounds like the Germans again Dan. ;-)
