Hi, does any one know of a "supplier or trade name" for a guard that I can fit to the bottom of my very steep roof to stop tiles from slipping onto the drive in a strong wind. I have seen these in Germany, every body seems to have them in the rural areas to prevent snow sliding down onto the...

Actually, I put the GROSS in capitals to indicate gross heat output (into water) and gross heat input of the gas, sorry if I caused some confusion, my apologies, but I used the basic energy formula for any % efficiency calculation. mechanical, gas burning appliances, electrical equipment etc...

namsag, I agree entirely in what "namsag" said in the following statement.:- "We all make mistakes and mis-diagnose or have an in grained view point the secret is listening to others and admitting our mistakes and altering our pre held views accordingly." I wish that more people...

"No Answer" came the stern reply! Brian. (one of the 3000 ? )

You will notice that the maximum rated INPUT is given in kW NET. This does not take into account the Latent (Hidden) Heat of Vaporisation of the water vapour in the products of combustion when an amount of gas is burnt to release this figure. This means that a certain quantity of heat is lost...

Would my gas tapping procedure work using the BOC regulator ? Ha! Ha! Worth a try Balenza, Ive seen some things on Towns Gas that would make you die laughing if it wasn't so serious. I have seen another use for bicycle inner tubes, forget the CO content of Towns Gas, the flame speed prevented...

Well,well Agile, so you post under your name which therefore makes you easily traced does it? Who in their right mind would want to trace you? This was only my second posting in this Forum so I am not familiar with the pros & cons of the functioning of the lines of communication within it. Why...

Point taken Dave, but when the operative understands how things work then the mystery of it goes, as does the desire to dismantle that particular item , not that anybody should feel the need to interfere with any meter governor that is under the sole authority of the Gas Distribution Dept.

So Agile, answer the man's question, how do they work? Tell him why they are spring loaded as opposed to weight loaded (as some of the earlier type) and why they use compensation governing! The man is only asking a simple question, after all, it is only First-Year Gas-fitters syllabus work...

Thank you "doitall", you have perhaps closed the approximation asked for, still further. :?

Try BS 2871 where '71 is the operative number. This should put you in the right direction. i.e.1971.

Breezer asked “which” & “why”. It stands to reason that the pressure at the terminal end of the two pipes will determine the resulting height of the water flow. Whether the pipes are vertical or horizontal, it is the pressure of the water at the exit of the pipe that determines the exit force...

] :o I did not expect such a swift response to my query, and so many people taking the time to answer it! Thank you Gents. There is nothing to beat first hand / hands on experience in todays minefield of unhelpful manufactures. Thanks again, it looks like an Optia then!! Ped, I take it with...

Hi, I'm soon to change my 13year old Ferroli Roma for an Ideal Classic FF 240 or Plumb Centers' Optia FF40. From this forum, I understand that they are identical boilers. But comparing the brochures of the Ideal Classic and the Optia I see that the Optia fan switch is mounted at the top right...

My first attempt at entering this forum! It seems that the difference is more than just a different badge. On looking at the Optia brochure showing the view of the interior, it shows what appears to be the fan switch mounted at the top r/h side of the heat exchanger, whereas the 08/99 brochure...
