Heating Help

Thanks Tim

@ May 25, 2012 7:00 PM in OESP 59th Annual Convention

Did Peerless show their new WBV 90% AFUE? Basically a WBV with a 2 stage oil burner from my understanding. By the way met to ask you if you had a chance to get a peak at Viessmann's new (to us) CM2? Thoughts, opinions? I like the no need for pri/sec great when retrofitting those modular boilers such as Hydrotherm, Slant Caravan etc. Thanks again for the report.

Anything New

@ May 24, 2012 7:26 PM in OESP 59th Annual Convention

Couldn't make it the show this year but surprised to see no posts about any new products or ideas. Like did anyone show any 2012 compliant cast iron gas boilers or is everyone still trying to keep them a state secret?

My Take On Conversion Burners

@ May 19, 2012 4:50 PM in Gas Conversion

If the installing contractor is willing to take the responsibility of taking over the remainder of your boiler warranty and the investment is better then go for it. Just remember you void the mfg warranty on the iron once you convert. Your putting a burner on a boiler that was not mfg approved.

Vitodens 100

@ May 16, 2012 8:20 PM in Lochinvar listens....

Would be the comparison. The boiler Mark posted has a lower firing end and the smallest 100 is 93k input. I love the approach but just not a fan of the hx if it is what I think it is. Too many bad apples with it in other mfg boilers and I can't get that taste out.

Not enough information on the combi to give a comparison to the Viessmann CombiPlus.

What Climate

@ May 16, 2012 7:50 PM in heated driveway

Are you in. Generally need 120 btu/hr per sqft in a 0 degree climate. How ma y sqft of of melt are you doing? That by the way is to get to a surface temp of around 37 degrees.

This should help and anwser your questions.

Is That

@ May 16, 2012 7:44 PM in Lochinvar listens....

A Giannoni hx? Love the low end but not a fan of the hx if it is what I think it is. Just too many bad past experiences with it. Now get that down fire hx to do that and its a grand slam. Love to see that atleast someone is listening and making strides to get a product out with a lower end firing rate. It has a home and I'm sure they will do very well with it. Hats off to them.

Vitocell 300

@ May 16, 2012 7:13 PM in Glass Lined versus Stainless Steel - Indirect HW Heater

Want the mack daddy of all stainless tanks?

You will pay top dollar but be assured its the last tank your customer will ever purchase. Max chloride acceptance before the warranty wouldbe void is 500 mg/ltr. See warranty.

Sure is

@ May 15, 2012 6:34 PM in Pex

The pipe is clearly marked as to temp and pressure ratings. All pex meets the same standard. Justt make sure if this is a heating system that you use a pex that has an oxygen barrier or you"ll end up with issues you don't want. Its tested to hold 80psi at 200 degrees.

@ May 15, 2012 6:24 PM in replacing heating distribution pipes with pex

You'll know more then this contractor will ever learn. Page 19 is what you want to do. Heck homerun and you might be able to get away with 3/8" pex. Make sure a heat loss is done as well as calculate the capable btu/hr output of the rads. You may find you don't need 180 degree water to heat this place. Also would have to make sure we protect that boiler if we are going to add outdoor reset into the equation.

Its the same curve as the 00R. What is the benefit of using this pump over the existing 00R? I was hoping this pump was in addition to the 00R to match the Grundfos 26-99 3-speed.

Post Pics

@ May 13, 2012 7:25 PM in trouble with a new system

Can you post pics of the boiler and zone piping? Sounds like its an air issue but if your purging it out and it comes back something is allowing air into the system.

What's Shutting Down

@ May 13, 2012 5:58 PM in trouble with a new system

When you say shuttig down, what do you mean? Boiler locks out? What error code are you getting? You need to post pics.

00R

@ May 10, 2012 7:51 PM in Heating Alert! - Taco

Its my understanding that this new pump is just a 00R with a new name. I thought it might have been their anwser to the Grundfos UPS26-99 but was told its just the current 00R.

Visa Gift Card

@ May 9, 2012 7:06 PM in Nat Grid/Burnham

I was doing some comparatives with the Alpine and its not all that great for the consumer. The program forces the consumer to spend the equipment rebate or lose it. For a few dollars that you would give up to go with another brand and get a better warranty may just be worth it to a consumer instead of this program. Consumer still gets the $800.00 utility rebate no matter then brand.

So Far Ahead

@ May 6, 2012 12:21 PM in Why Is the US Always Last

Viessmann is so far ahead of even their competition over there. Rumage around other sites such as ACV (Triangle) Bosch and Baxi Group and yo don't see this stuff. Love to see that wall hung condensing oil make its way over.

Heat Loss

@ May 5, 2012 6:43 PM in Need help with heating & hot water setup for tight space

No way you need 100,000 btu/hr is heat that space. You have no loss above and below. Does the existing boiler vent into a common chimney or is it its own?

If common how about. Burnham Series 3 of appropriate size, it's 33" deep and much slimer.

Not only poured but jacketed and shipped too.

2013

@ May 5, 2012 6:26 PM in Why Is the US Always Last

ME my source told me, heating season Sept 2013. Scott I hear ya. I too rumage thru the german site every once in while to drool. Its only a matter of time before the American boiler manufacturers plug into the honeywell red link might as well beat them to the punch.

You Would Think

@ May 5, 2012 7:35 AM in Why Is the US Always Last

The segment of the boiler market that's growing is the condensing boiler. This is not new for them been around a couple of years and its nothing more the putting the same control face on the Vitodens 200 and Vitotronic controls that are here now.

If Viessmann really wants to explode in the US market this platform in my eyes gives them an opportunity to get US consumers what they love, Gadgets. We all pretty much have a love relationship with our IPhones and the ability to show a neighbor "look what I can do."

Couple Of Concerns

@ May 4, 2012 7:53 PM in Primary/Secondary piping

The spacing in those tee's look like they are more then 4 pipe diameters apart and not much straight pipe exiting the tee heading into the boiler. Another concern I have is delta-t between boiler supply and return.

Why Is the US Always Last

@ May 4, 2012 7:46 PM in Why Is the US Always Last

I was poking around Viessmann's British site knowing this has been available for some time across the pond wanting to keep up and it got my wondering, why is the US always last? The Vitotrol Showcase app is pretty cool. Simple for a homeowner and could be a great service tool for a contractor if the installer can actually get error codes and can get into the coding.
