Are any pool or cleaning chemicals stored nearby? Even very same amounts of chlorinated products will chew through a vent in a very short time.

@ November 20, 2002 10:17 AM in Burnham info

I think the Burnham reps frequent this page and aside from that - there's a lot of bright minds out there too! I am converting 2 - Burnham boilers (810 BWI, ser # 7506778 and 7506781) with the Robertshaw gas valve model # 7000 DERHC - LP - S70. This is a LP to Nat Gas conversion. Where can I purchase the nat gas reg kits??? My local supplier tells me that he can only supply the complete valve! I'm not worried about the main burner orifices as I can drill these out and replace the pilot orifice as well ... but that gas valve ...

Sea Hunt???

that would have been an actor by the last name of Bridges - No? As in Lloyd, daddy of .... My Mom worked for a lawyer - DAD heavy construction - we had the only TV on Westminster Highway in Richmond B.C., we were by all standards - well off. When CBC wasn't on the air (about three hours a day) - we had the Indian Chief with full headdress on air - or the KVOS nuclear ready signal (in the heady first days of the cold war and Cuba) from Bellingham Wash. All this in the days when asbestos was thought of as the fiber for the future - go figure ...

@ November 17, 2002 8:48 PM in IN FLOOR HEAT WITH HARDWOOD

aluminized cardboard which can be used for return air ducting in scorched air systems. I would prefer the relectex (double bubble, aluminized plastic) as a minimum.

that Fury is not to be confused with Black Beauty, Flicka, Champion (Gene Autrey) or ButterMilk (Dale Evan's nag). Lone Ranger rode Silver. Nellie Bell was a Jeep (about a 49 post war C series) and just a few words sent me and a good friend wandering about in our youth. Who says this is only about heating???

I'm not sure...

@ November 17, 2002 8:29 PM in Could we add snow melt?

it's a 200 amp service single phase - three phase would be better - and even at a couple cents a kwh it would be pricey. Electric would be cheaper (less expensive) to install initially but in the long run ??? - maybe we should plan on a second boiler dedicated to the snow melt. I would dearly love to offer the better alternative (having read Dan's book on Just add h two oh) and as mentioned in an earlier post - I think I should run the hpex back to the boiler room while the ceiling is still open. We're running 2 pound gas in the home so supply of nat gas is not an issue - neither are the depth of the ho pockets - but he's not foolish either - he will opt for the better design. And as an aside - it was a good day hunting - just finished the dressing chores on a nice 4x5 whitey - that would be a nine point for those south of the 49th. My last one was a 6x5 and he too was caught napping! Cheers from the Canadian Rockies

electric snow melt -

@ November 17, 2002 11:43 AM in Could we add snow melt?

I'm not sure which product will be used for this. I am considering adding tubing regardless - but Dan is right - we don't have the resources (btu's) to presently add snow melt with the current boiler. At 600 sqft and 150 btu/sqft - 90000 btuh is my first guess at heat required. Re cracking - like tubing, electric cabling must be protected at the stress points. Cheers

My experience is ..

@ November 15, 2002 8:41 PM in Could we add snow melt?

with the Viessmann products - mainly the Vertomat in the larger commercial applications and have been doing the setup and service for most in the interior of B.C. They are a sweet boiler and a dear to work on - and of course all the less expensive mfgers models would all work equally as well. We had a very serious jobsite meeting this am - and it looks like electric snow melt has won out. Given that this has been a late development - I'm not unhappy with the decision. With all the boiler room piping complete it would have been a bear to redo. I'll post pics once complete. Once again the folks on the wall has been superb with ideas - HR - we have to meet - too bad we didn't cross paths at ISH - maybe in Vegas?? It is - afterall the best party town in the world. The golfing isn't bad either. Cheers from the Canadian Rockies ---

good info -

@ November 15, 2002 8:25 AM in Could we add snow melt?

Since Dan's post - I have been scratching about various sites. I would estimate - 150 btu/ft as minimum - @ 1"/hour and an average winter temp of -10 C. Boiler is too small - HR may have offered best idea - a vitodens hanging on the wall would be sweet - and it was my original boiler suggested for this project - but at $6500 plus ...... Maybe we don't have to snow melt the whole deck??? Just where the valleys of the roof dump all the snow ... just thinking out loud.

Snow melt ???

@ November 14, 2002 11:46 PM in Could we add snow melt?

We're just in the final stages of a radiant (injection) system. All piping is complete, manifolds tied in - Tekmar 356 will be completed later this week. Customer has been a prince throughout - wanting quality components. Estimated heat loss is 56,000 - boiler net is 63,000. Customer now wants to add snow melt to about 700 square feet of deck. I have been looking for a btu/sqft value for snow melt but haven't found it - I left the customer hanging with the "it depends" answer this afternoon - and I will be chatting with the heaing designer tomorrow. The original design didn't consider any snow melt - and the electrican tells me that any defrosting sytems he has installed aren't appropriate with this install. Can this boiler support additional snow melt? OS design temps here are -22. Comments??? Cheers from the Canadian Rockies Glen

ISH -

@ November 4, 2002 7:24 AM in ISH

It doesn't surprise me that most folks beat me home - with a 4.5 hour flight and an equal length of time driving - it's not hard to do. I took in both of Dan's classes as well as John S's - Lady Di (the other partner to this enterprise) took in Ellen - and of course we bought more books. I though one of the most interesting discussions was the new hydronics code - While some have been following the guidelines of the RHWHA of BC - the national code is a great start. Does anyone know how the discussions with the RPA went as there was some interest in a national/federal code south of the 49th as well? Re ISH next year - judging by the Toronto show - every wallie should attend - and perhaps we could formalize an hour or two where wallies could down a beer or two together - while putting some faces to these emails. I have gained once again by attending the seminars - and now my brain is swirling with more possibilities than ever! Cheers from the Canadian Rockies.

Bacharach vs who?

@ October 28, 2002 8:35 AM in Bacharach vs. Testo

I have always used Bacharach analysers - in every setting from residential furnaces to 18,000 hp boilers - with excellent results - the only visible downside is that we must ship to Ontario (from B.C.) for annual calibration. I have - when necessary used the Kane May product (KM9106) with all the bells and whistles and it too is superb - and will update the Bacharach to the Kane May KM900 later this year. Look them up - www.ueitest.com

Twisted thinking?

@ October 22, 2002 12:57 AM in Piping Materials

Thanks for the excellent feedback - I am just now starting a very sweet radiant job lakeside near by Cranbrook. It's an unassuming 2500 sqft log cabin in which the owner is sparing no expense. It will be a very nice spot to crack a bottle of wine and watch the sun go down. I have sorted it out with the heating engineer that injection temp control will be the most beneficial to me and the owner (on top of the 90% furnace and 4 ton AC) but I am thinking - with so much flash above the boiler room - wouldn't it be nice to offer a system that looks as good as it works? I would prefer to do this in black - but thought I would ask. And - I'll see many of you at ISH next week. (Look for the white haired character under the cowboy hat!) Cheers Glen

@ October 21, 2002 8:49 AM in Piping Materials

Hello All - Having followed many threads - and looked at many great examples of fine work - I must ask this: Is there a preference of piping materials for the near boiler piping? I have used both copper and steel (A53) While the copper is pretty - the steel is much less expensive to install. Comments? Cheers from the Canadian Rockies

This is not as crazy as you think -

@ October 14, 2002 12:47 AM in Wood boiler/system

in some jurisdictions - wood and oil are considered to be solid fuels - and share common breeching and flues. Where I see problems is the lack of barometric dampers to control draft when the wood side really kicks in. Here in the rockies of BC - we have many wood/oil combination scorched air furnaces - which generally work well until the HO stokes up the wood side and burns out much of the firebox. And there are still a number of really good combination appliances being built and installed today. Different strokes for different folks I guess. Cheers - Glen
