Hello folks... I was referring to the combustion (gas/air) system, similar to what was used in the old German V1 "Doodlebug" cruise missile of WWII, and it is apparently pretty obvious that you don't have any (or hardly any) of those types of boilers/furnaces/heaters over there. Thanks for...

Hello Folks, my Canadian (Alberta) professional registration/certification apparently does not qualify me to post on the "official certified" forum, so here's the question... I am wondering if anyone in Europe is using or playing with the system used in the "Lennox Pulse G21 (or similar)"...

I think there is a difference in terminology, but regardless, your home electrical feed/distribution panel must be connected to some form of ground (rod?), which in turn must be connected electrically (path wise) to the "neutral" conductor from the electric utility. The residence "protective"...

You are absolutely correct...

Well, how hot you keep your water has a direct effect on how much scaling/deposits occur in your system, just check out your tea kettle/coffee pot for confirmation. We just moved and purchased a home, could not figure out why the hot water pressure was so low. Investigated and found horrible...

So, anywhere on this planet, electricity requires a source and a return. The more sophisticated countries also require a separate electrical protective ground, the so-called "third" wire in the domestic electrical circuit. I am unfamiliar with the wiring regulations in Europe, but have a good...

I should have mentioned that I have this Ecodyne at the cold water input to my domestic hot water storage tank (indirect type of about 40 U.S. gallon capacity), as the hot water system is where the calcium carbonate buildup is usually worst. My boiler is original, but have a 50% propylene glycol...

Have had the Ecodyne Phosphate water treatment system (made for Amana) which uses polyphosphate crystals, for nearly 30 years, have experienced no problems with scale buildup in water pipes or faucets, all are still original (copper piping and Moen faucets). A typical crystal charge lasts about...

Dear All... If anyone can PROVE via the "simple test" that I described in an earlier post that their device works, then I'll concede that there is an alternative to the ion exchange (or alternately the hexametaphosphate) method of altering hard water properties. Until then, "hokum" is the word...

I don't know what wireless protocols are being used by the HVAC industry, but if you have the time and inclination, it should be relatively (depending on your skills) simple to build your own home automation and monitoring setup using the latest wireless technology in the ISM (Industrial...

Have a peek at http://www.polypipeinc.com/ for some plastic gas pipe, also over here more and more new homes (all price ranges) are being piped with PEX for the domestic water piping, a plumbing company friend tells me that this stuff is just as reliable as copper, the quality of the...

Hi Nige F... Over here plumbers and gasfitters are in the same trade, just different levels of licensing (industrial vs residential, etc.). I really don't think any one group is better qualified than the other, it is really a matter of training and experience, especially on the high efficiency...

Hello All... I see the debate rages on even 'though the basic ideas have been regurgitated many times, and that is that every product has it's place. I have been researching residential boiler systems for the past year and have been amazed at the animosity displayed by people who should know...

Hello all again... Thanks Tony for this most important point, and this is how most consumers get disappointed with some of the less knowledgeable HVAC service people out there. Hopefully Mickymoody is able to trouble-shoot and resolve his problem successfully (without purchasing a complete...

Dear all, I apologize for submitting my former post, complete with the secret general operating information for ALL residential boiler systems. I am truly sorry for any implications that I may be an accredited member of any formal HVAC association, I thought I said I was in electronics. Tony...

This is an interesting problem. Was wondering if you have the same Ravenheat LS80 installation and operating manual I looked at located at http://www.ravenheat.co.uk/pdf/manuals/LS80printV3.1.pdf to ascertain exactly what is supposed to happen and when with your boiler unit. Have managed to...

I believe "gasgas" hit the nail on the head with "How does a 'magnetic' in line scale inhibitor work? I havent a clue. When did you last encounter magnetic chalk?" . Anyone wanting to verify this can scrape some (as much as you want) of the buildup out of their water line and mix it in a...
