Talk:Condensing boiler

message: Questions:
  
1.  Is it true that copper pipes should not be used for draining away the condensate, as the acidity of the condensate will react chemically with the pipe and eventually cause a blockage which stops the boiler from functioning? 
Copper pipes can't be used, but not for the reason given. When the flue gases condense, a certain amount of nitric acid is formed, imparting acidity to the condensate. This will react with copper to form highly soluble green copper nitrate. The pipe will be eaten away from the inside. That in itself won't cause a blockage, however, aluminium heat exchangers tend to create crystals which form in the condensate which may cause a blockage.Nick Hill (talk)
2.  Would it be okay to connect the boiler condensate outlet to the (plastic) discharge pipe of a sink, using a plastic pipe for the connection? 92.24.32.32 (talk) 17:26, 17 May 2009 (UTC)
thread_title:  Condensate Drainage  

message: I am a boiler novice reading the article for information. There is a sentence "To economically manufacture a condensing boiler's heat exchanger (and for the appliance to be manageable at installation), the smallest practical size for its output is preferred." I initially read "output" to mean boiler heat output (i.e. kilowatts), as that's what output usually refers to in this context. Having pondered on why this should be without success I now think it refers to the physical size of the 'exhaust pipe' (or whatever it's called) leading to the flue. Could someone who knows clarify the wording to make things clear?  — Preceding unsigned comment added by Mark Triggers (talk • contribs) 08:31, 17 May 2015 (UTC)
thread_title:  What "output"? 

message: To refer to the complaints of some users of condensing boilers as 'myths' is just hocus-pocus.  In my particular case, a five year old boiler totally failed due to the heat exchanger disintegrating.  This is not a 'myth' as I did not make this story up.  And I am aware of others who have had similar problems with heat exchangers failing.  Please do not refer to actual problems as 'myths' unless you can substantiate them as such.

replies: text: So source this. Yes, some boilers have failed after 5 years. It has more to do with quality, than with condensing per se. Andy Dingley (talk) 22:06, 27 March 2016 (UTC)
replies: text:  The difference is that the section here already has sources. Andy Dingley (talk) 22:59, 27 March 2016 (UTC)
thread_title:  Remove "myths" section 

message: I improved the Building Research Establishment section, and fixed the dead ref. But the section still sucks. The section should be eliminated, and any useful information from the ref should be integrated into appropriate places in the article. Alsee (talk) 16:27, 28 September 2016 (UTC)
replies: text: I would keep this section together, even if it moves into some other broader section on myths. The point is that a reputable body addressed the five main reasons cited against them - just look at the talk: page here for how persistent these are.

message: "A more significant issue is the slight (pH 3-4) acidity of the condensate liquid." i changed the term from 'slight acidity'. first i opted to remove slight, but then i settled with the current version because,(based on the pH value given in the 'exhaust' section) on the one hand it is 'slight' in the 'common sense' meaning it isn't a concern for the skin, on the other hand it is quite a concern in the technological sense for the corrosion effect in the long term operation. so to remove the ambiguity of 'slight' i added the pH value to this sentence (in case someone is not reading the article further - which happens to me quite often.) 80.99.38.199 (talk) 17:03, 5 October 2017 (UTC)
thread_title:  section: reliability 

message: At least in Germany, France and the Netherlands, condensing boilers have been the standard for decades. Since around 2010, conventional boilers can no longer be purchased in Germany, and only condensing boilers have been installed in new gas boilers since around 2000.
In Germany, there has been a law for years that conventional boilers older than 30 years must be replaced by condensing boilers. Reliability of condensing boilers is not an issue (mine is from 2001 and runs without problems, provided some maintenance). The whole discussion about whether or not to use condensing boilers seems baffling, if not ridiculous.
