Great minds

@ February 23, 2014 2:54 PM in Rinnai RH180 or 100 Gallon Atmospheric?

Great minds think alike!


@ February 23, 2014 2:53 PM in Rinnai RH180 or 100 Gallon Atmospheric?

   How about manifolding multiple tankless units (I don't know what their GPM requirements are)? I have heard good things about the Eternal's as they have a built in tank to prevent the "cold sandwich". You can manifold the PVC venting so you only have one exhaust penetration, intake can come from inside or outside. Caveat, I have never used this brand so my opinion is based on hearsay. Most, if not all manufacturers at this point have the capacity to cascade multiple units to provide whatever GPM required.


To better serve

@ February 23, 2014 2:07 PM in manifolds in series?

   To better serve the customer, I would try flushing the system and re-piping it using a flat plate heat exchanger and non-ferrous components for all of it, not just the remote manifold. After all, the heat comes from the boiler not from the remote manifold with the non O2 tubing. I have non O2 barrier PB systems that have been working for over thirty years.
    With a heat loss of 25K BTU there is no reason for an electric back-up but you definitely need a buffer tank with a boiler of that size. You can reuse the the water heater as a buffer tank or put in a real buffer tank that will fit. I understand space is an issue but there is probably a buffer tank that will fit your application.

Sorry, I missed that it was a combi. Use the combi as as designed, and use the electric as a buffer, or install a real buffer

   I'm watching the Daytona 500 and trying to use the computer at the same time. I have a hard time walking and chewing gum as well :) 

   As Mark said, post some pics.

You posted this in the Domestic Hot Water section. Try re-posting in the steam section.
Post some pictures of the install as well. Your description is difficult to understand.

And if your boss doesn't believe in skimming a steam boiler, he has no business installing them.

I'm with Z-man, purchasers don't want to worry about replacing their boiler when they buy, they want move in and decorate ready. High efficiency is also a big selling point. 
Bob, If you were to replace the boiler and put a sticker on it with whom and when to call for service you might just gain a customer. Versus losing the one who is moving away.
Scott, Instead of running pipes outdoors and insulating, why don't you save yourself some money and time, just remove the baseboard (trim that is). , cut 12'' of drywall up from the floor, run your pex and re-drywall the 12" all the way around and reinstall / replace the baseboard. Only one seam to drywall and you will use less pipe, not have to insulate and you will make the home ascetically more pleasing. I have always re-painted the homes I have sold in a neutral color anyway. You are going through so much effort as it is, why not do it the correct and easy way? You could probably run the piping in a day.


In a pinch

@ February 22, 2014 3:48 PM in Advice on Rare Old School "Dual Flow/Bypass" Radiator Valve

In a pinch, Use a copper tee and solder in a vane made out of copper. It has to extend through the male adaptor as far as the original. It's a pain in the a**, but if done right, it will work. You will have to remove the spud. You will not be able to shut it off unless you have enough room to squeeze in a valve. And unless you install a bypass, the valve will shut of the entire loop.


C.I. radiator

@ February 22, 2014 1:33 PM in Can't Get Baby's Room Warm

I would go with Ironmans solution. A cast iron radiator, sized to match the heat loss of the other rooms will prevent the boiler from short cycling as it will if it is on its own zone. You already have the existing piping off the same loop as the other bedrooms. Used cast iron rads are not too hard to find, just make sure that is is the right size.



@ February 20, 2014 1:52 PM in Scott's radiant heating project

What type of heating system is in there now? What was your heat loss? Exposed piping? This must not be a luxury home?


Combustion Analysis

@ February 20, 2014 1:35 PM in Solution for consistent E8 Fault code on Viessmann Vitodens 222-F LP Boiler?

Was a combustion analysis done on the unit?


@ February 20, 2014 1:19 PM in Not Enough Radiation?

How are the convectors mounted? I cannot tell from the picture. Is the picture from the top, looking down, from the bottom looking up or from the side? They should be mounted horizontally so that the air is pulled in from the bottom, goes through the fins and exits at the top. The picture looks like it is mounted vertically

Why line a chimeny when you can do that?  :)


Dear John

@ February 19, 2014 2:17 PM in atmospheric boiler for coach house?

  John, I don't know about your locale, but where I live we are not allowed to install any appliance with an open flame in a garage, 18" off the floor or not! I would not risk my company, my license or my conscience in doing so. Please do not advocate bad advice. This is straight from the Lochinvar manual for that boiler.

DO NOT install this appliance in any location where
gasoline or flammable vapors are likely to be present.

I don't know about you but I keep two cars, lawnmower, weed-eater, yada, yada ,yada,........ in mine.

To the OP, go with a wall hung a mod-con and don't worry,be safe. They do make sealed combustion power vent boilers, however, by the time you assemble the stand and wrestle a hunk of cast iron onto it and vent it, you've offset the cost of the mod-con. If you go with a fire tube heat exchanger you can probably pipe it direct rather than primary / secondary.



@ February 19, 2014 11:39 AM in How serious an issue is water quality?

Do you use the filter first and then use the anode assembly or are they one unit? I only watched the video (english version), and it sounds like they are separate? It looks like a nice product if it works as advertised. How long has it been in use for?



@ February 19, 2014 10:51 AM in atmospheric boiler for coach house?

No! You need a unit with sealed combustion, especially if there is a living space above. It may not be code in your locale, but it is the only safe way to do it. Use a modcon and save space and money on fuel (you don't have to put another hole in your roof either, usually).



@ February 19, 2014 10:41 AM in Munchkin Boiler Problem

Could you post some pictures of the boiler, near boiler piping and the intake / exhaust piping (including the terminations on the outside) ? Most problems are due to installers not following the installation instructions. Modulating / condensing boilers have to be piped in a specific way to operate correctly, especially boilers with your style of heat exchanger. Pictures would help greatly, the more detailed the better. Though I have seen boilers that were lemons, they are very rare.


I'm Done

@ February 19, 2014 10:22 AM in how prevalent is this?

I'm done with this post.

Moving on.



@ February 18, 2014 4:40 PM in how prevalent is this?

I will refrain from responding to your post the way I would like to. The people on this site are here to HELP other people. As this is your first day on this site, I can only conclude that you are in some way related to the MMM site as you are only condoning poor practices. The only comments that I have seen on this post (other than yours), were made to ensure a safe and functional system.

 As there is a link to this site posted on MMM I don't think that it is anyone's responsibility to go there and correct the system that he designed and will not work nor be safe. If MMM wishes to learn about the correct way to install a radiant system, he should come here and find out how to do it , The folks here would be more than happy to help him. All he is doing is showing people how to do something the wrong way, with the wrong equipment and it will only cost them more money down the road as they will have to pay an experienced pro or allot of time and effort on their part to correct it.

I would rather have many of the folks that lurk here remove my gall bladder than some of the doctors (or engineers) that I have dealt with.

Hot water baseboard heating (new old thread)

@ February 7, 2014 1:07 PM in Hot water baseboard heating (new old thread)

For everyone who is sick of scrolling through 525 posts.
Hot water baseboard heating
we just converted from oil with a Burnham burner, 14 years old, to gas with a high efficiency Alpine burner, and we have baseboard heat. The oil heat was quick, heating the house 5 to 10 degrees in about 15 minutes. the gas heat with the Alpine is so slow, heating the house about 1 degree every 20 to 30 minutes. is this normal? the company who installed it said it is, and that if we want it to be more efficient, we cannot turn the heat down. this sounds crazy, and we do not want the heat so high while we sleep, and prefer to turn it down, but it is so slow to heat the house, and so it is cold in the morning for hours. can someone elaborate or help with this?
