As said you didn't know how an why. Now you do so stop digging a hole for yourself. Just say, "thanks Doctor Drivel I didn't know that". Much easier that way.
can we change to a combi?

As I said you didn't know but keep digging a deeper hole. Best be quiet.

You really are dim, the over 100% claims have been around since condensing technology began, I have been involved with condensing technology for many years and have been aware of this form of calculating efficiencies, but as I live in the real world I have always used the correct scale of within 100% when quoting efficiencies of boilers to customers.
You carry on believing the suckers form of calculating efficiencies, just don't bore the reste of us with your drivel

As I said you clearly haven't a clue why it is used. Slapping a boiler in the wall doesn't mean you know condensing technology - as is all too often the case with the "plumbers" who spout loud and long here.

I fully understand why some European manufacturers use the over 100% method, but we live in the UK the procedure here SEDBUK is within the 100% bracket.
I fully understand condensing boilers, I do not simply slap boilers on the wall, I design and install efficient heating systems I have loads of satisfied customers, what actually is your field of work, I design and install heating and hot water systems in new build houses, so what do you do to make you think you can preach to me.
Unusually billy bob, may I offer you some constructive advice, just ignore drivel and his drivel, all he does is search the internet and read instructions. He has never even seen any boiler he talks about let alone fitted one or commissioned it.
Save your breath, he is just a wind up idiot who is dangerous to posters on here who may be stupid enough to listen to him. He does not understand the difference between nett and gross efficiencies as we do.
He changes his mind on what he says more times than I drink pints of lager, you should see the size of my beer belly

I will take your advice, thank you

I understand that.
As I have already stated I am talking about LATENT HEAT or to use the more modern term " Enthalpy of Transformation".
Yes, but the latent heat in a condensing boiler has been produced by the boiler within its specified capacity, the boiler simply catches this latent heat and extract most of the heat from it, I say most as some still goes out the flue, but this heat is still from the heat that the boiler produced, the fact that a small amount of this heat escapes out of the flue proves that the boiler has to be less than 100% efficient 95%-98%
So this is a load of rubbish in the following link compiled by Viessmann then......... ?.

As I have already said, I know how they come to these figures, but they are not accurate, the flue gasses are heat that was created by the boiler, what they are claiming is the boiler fires and heats the water to 98% of it efficiency, it then claims that the flue gasses that accounts for 2% of the heat that is left according to their figures, all of a sudden changes to 11%, where do they get this figure from, they call the flue gasses additional energy, it is not additional, it is heat that was created by the boiler, the fact that some heat goes out of the flue proves that the boiler cannot be working to even 100%, no heat could be lost from the heat transfer to acheive 100% efficiency. this brocure would of come from a German translation, that may be how they do it in Europe but in the UK we work to SEDBUK
There are no other suckers like Drivel - his type of sucking is quite unique.billy bob said:
Have to disagree there softus, as you know yourself watersystems sucking technique is identical to drivel's. Perhaps they're boyfriends or something.
I think you might be reading too much into the phenomenon of coincidence, sooey.
Just because Doctor Drivel had a nine-month posting break, then started up barely again two days after Water Systems' final post, it doesn't mean that the same person is behind both member names.
Or does it?

I suppose you're right, it's probably just me being cynical. Lets face it if they were boyfriends they would have bored each other to death long ago.
Put it this way Dave, there both a pain in the ar&e.
