The manufacturer's information will tell you if primary/secondry is needed based on the total restiction of the system. My guess is that it will be necessary. The only time we can eliminate P/S piping is on an old gravity system, with incredibly low head-loss.

Ok, so now who's going to test this against a storage tank type water heater?

Sizing

@ August 1, 2014 7:58 AM in Oil to Gas Conversion

When it comes to steam, there is no such thing as "too close". There is right and there is wrong. That's it. The IN5 is the better match for your current system. If you plan to add more than one radiator in the future, go for the IN6 with a two-stage gas valve. High/Low firing schemes will smooth out a little bit of oversizing.

5" is correct size according to my charts. It's on the low end, but 4" would be too small.

We install up to 6" pipe with a 5ft wrench. What's the problem?

Steam

@ July 29, 2014 9:21 AM in Near boiler piping issue?

You are correct that the piping is not correct and will lead to carry-over and innefficient steam production. We see A LOT of poorly installed commercial/industrial systems like this. Usually, the cost to repair the piping is seen as excessive by management. In reality, you'll make a large improvement in most of your problems by fixing this. And you'll save on fuel costs as well.

Piping

@ July 27, 2014 10:27 AM in Burnham IN4 steam boiler piping

You are correct that the piping is NOT correct. The equalizer/drip back to the return should be located after the main take-off. The way it is now, you are not going to produce dry steam and may lose a considerable amount of steam capacity going out to the system. It needs to be redone.

Boiler

@ July 27, 2014 10:24 AM in Another Steam Boiler Sizing Concern

Under-firing a burner in a wet-based boiler will INCREASE heat transfer and combustion efficiency. So, it's actually better to use a slightly oversized boiler, and use the correct sized firing rate.

I thought that the Intrepid was approved for gas. A quick call to Slant/Fin would confirm that.

Any power burner, whether its oil or gas, will run around 85%.

Boilers

@ July 26, 2014 8:23 PM in Another Steam Boiler Sizing Concern

Most atmospheric, natural gas, boilers will not operate above 82% combustion efficiency. A wet-base and power burner combo will achieve 84-89%, with the added bonus of being able to fine tune the proper input rating. You can "under-fire" and power burner by about 20% without any problems.

Can you post a few pictures? We'll be able to tell you exactly what is right or wrong with it.

Gas Valve

@ July 26, 2014 7:41 AM in new home owner from philadelphia

Low Fire is 60%. It is non-adjustable as far as the manufacturer says. Though, I'm sure there is a way to adjust it with a new spring under the Low Fire solenoid valve. However, 60% seems ideal for steam because Low Fire almost always matches the connected EDR load.

I'm a trained installation/service contractor for Panasonic. Are you looking for sales or service?

Update

@ July 25, 2014 7:14 PM in new home owner from philadelphia

Well, this mess was finally cleaned up today.

We replaced all of the piping. Corrected the bad venting connections. Added a massive amount of main vents. And installed a 2-stage GCV with Vaporstat to run on High/Low. After firing, the 60-70ft main was hot in under 5 minutes.

Boiler

Which contractor measured the radiators to find the right size?
Is the existing boiler sized correctly?
Did anybody find out what might have caused the old boiler's failure?
Are there any other upgrades that were mentioned about the entire system?

Radiator

@ July 16, 2014 5:53 PM in Converting One Pipe Steam Rads to 2 Pipe Hot Water

If it's not connected on top, it won't work very well. Do you have a picture of the entire radiator, or a name on it?

Are you converting a steam system to hot water?

Mod/con

@ July 15, 2014 7:47 PM in Mod/con poll. Installers only.

#1.

We don't install low-efficiency anything. It's just not our style. If properly installed and maintained, the mod/con will deliver all of its promised results with the same amount of maintenance and service as a CI boiler. Yes, SOME of the parts are more expensive, but that's the risk we take for improved comfort and fuel consumption. I see it as a good reason to get your customers signed up on a service plan that will dramatically decrease their service costs.

Plus. natural draft is an evil mistress. I'm all for anything that uses sealed combustion and releases a home from the inefficiency of a chimney.

Reality

@ July 10, 2014 9:19 PM in CO deaths because someone cut off the exhaust:

I'm going to print this article and hang it around our shop. A horrible event, but a good reminder for everyone else to be smart, and never leave a system in an unsafe condition. I always encourage my guys to spend the last 10 minutes of every job just standing back and looking around the basement/attic/house/whatever. Sometimes it takes a relaxed mind to notice something that was right in front of you all day.

Well...

...this threads going to be deleted, too.

Maybe just keep the first couple of posts?

Otherwise, that would be a pretty boring display.

@ July 8, 2014 1:30 PM in Can I add hydronic furnace to steam system with IWH?

You can tie a circulated loop off of the steam boiler as long as the capacity does not take away too much from its ability to maintain steam for the rest of the system.

Where are you located? We may know somebody who can handle all of your systems.

What city? You obviously have not found a true steam professional.

50%

@ July 7, 2014 6:52 PM in Getting into mod/con business

I lose you when you say that a mod/con can't reduce fuel consumption by 50%. How is that impossible? I can turn the boiler off completely, and it will save 100% fuel.
