Thanks for trying, gdavis.
I've checked the instruction manual as well as the brochure and see only 1 inlet and 1 outlet.

See page 24 and page 25 here:

http://www.saturnheating.net/sites/www.saturnheating.net/files/Oil-Boiler-Instruction-Manual.pdf

It would be against all EU rules and the WHO guidelines as well to use the same circuit for DHW and space heating circuit.

As far as I can see this saturn machine is a plain oil fired CH boiler. Where one can switch between two pre-programmed outlet temperatures. It has only 1 inlet and 1 outlet. Therefore it is not a combi-boiler.
Nowhere the manufacturer/seller claims that this boiler is a combi boiler. As far as I can see....

The technical specification on page 33 tells the same story:
" heat efficiency of 95% normal" and "hot water efficienzy of 95%"

With a combi-boiler feeding fresh cold water condensation would be achieved since the cold heat exchanger would cause it. The efficiency of the DHW would be higher than the efficiecy of the space heating circuit, plain logic.
B.t.w.: I have never heard of any boiler operating in a non-condensing modus delivering a 95% fuel efficiency.

To what standards have these efficiency tests been done ?

From the brochure:

http://www.saturnheating.net/content/nhc30b-condensing-oil-boiler

Key features

Condensing efficiency of 101%.
A straight forward lie that is, no boiler can condense more vapour than there is (100%).

Usually the manufacturer would tell this (EN or BS or similar), it's a legal issue. Not with this one, as far as I can see.....

Would you mind to clarify, gdavis? Maybe a link to a more detailed explosion drawing, pictures showing the exact build-up? Thanks


@ the OP: there is nothing like an oil fired combi boiler in domestic sizes available. Contact a professional heating engineer.


And @ those who have seen this thing operating: what efficiency is meassured in-situ?

I've found this warning in the saturn brochure:

The domestic hot water supply is not
recommended for potable use.

@ sullz:

Your recommendation:
Excellent boiler
- how do we take this? Excellent for hospital admissions ? Excellent for dialysis apperatur manufacturers?

What is potable domestic hot water ?

In legal terms?
Legally binding for Irish builders, plumbers, heating engineers?

Thanks ....

Heinbloed , i dont think that i could possibly try to explain the workings of that boiler to you as from your posts i have seen from you in the past , you are not able to take any correction of your opinions , i think the best thing you could do is contact pulsar direct and ask for ken , he will be able to answer any questions you have about it because im not going to spend my saturday evening entertaining your idiotic points , you dont have a clue about this boilers operation .

The saturn home page



claims to have an oil fired condensing boiler available with an efficiency of 101% and shows a Sedbuk label "A".

There is no oil boiler listed in the Sedbuk (manufacturer-) list with such an efficiency rate, see:

http://www.sedbuk.com/cgi-local/result1.cgi

The highest efficy rate is 93.3 %. Not more. Technically impossible. A 101% efficiency rate according to Sedbuk is HUMBUG.

And in the search facility of Sedbuk

http://www.sedbuk.com/cgi-local/searchpg.cgi

the manufacturer "saturn" can't be found, it is non-existent there.
The Sedbuk page was recently updated, 31/1/2012. Four days ago.

Have you been fooled by a telephone sales con-man, Sullz?
Contact the consumer organisation, there is help.


PS

The Sedbuk brand list (not the manufacturer list !) has a "Saturn" boiler listed, an oil fueled combi boiler ( I'm wondering and learning). See

http://www.sedbuk.com/cgi-local/detail.cgi?fone=000268&ftwo=NHC&fthr=25B&ffou=016720&in_blank=123

But listed there with an efficiency rate of

SAP 2009 annual efficiency:
89.4%

So this can't be the same, can it? Not efficient enough to satisfy the legally minimum standard in Ireland ( <90% , " Band A " ). But recommended - why?

I think your on to something here, potable water is water you can use for cooking pots, so if you can't use it for the kitchen then what good is it

Well, since there is no contact detail mentioned we have to rely on what we have available, the www....

We look for the term "Pulsar" in google and find

http://www.wanderport-ir.com/index.php?pg=products

A microwave heater. Sure they state 99% + efficiency. But no Ken would claim 101% efficiency with direct electric usage.

Is there a mix-up with brand names, company names and manufacturer names? And the types of products ? Maybe on purpose?

This brochure

http://www.pulsardirect.com/sites/www.pulsardirect.com/files/Oct11IE.pdf


talks about

UBELIEVEABLE FEATURES


Now, if this isn't a statement....

So we check the www further, try to refine the search to an Irish company. And we get to

http://www.pulsar.ie/heating/boilers.html

Firebird, Wolf and Vaillant. No "saturn"....

Could it be that someone is trying to sell surplus stuff which doesn't European min. requirements for efficiency (building regulations)? Trash?

I haven't seen neutralization units installed with new boilers for a decade, at least. With that saturn thing we get one with it, free of charge. This boiler must have been designed decades ago, in my opinion. Hence the warning on the hot water quality, not for potable use ...


We have seen previously boilers recommended in this forum which do not meet minimum efficiency and hygene standards.

Heinbloed you are as mad as a brush, what do you think potable water is , ive fitted these with great results , im not going to entertain you much further , there are contact numbers in the brochure and on the website if it is really bothering you that much . im really beginning to think that you are not experienced in the trade and havent got a clue.

I dont think he does , i think heinbloed is under the impression that the hot water you draw off is the same water as in the heating system at a lower temperature.
As i said " mad as a brush"

And he'll likely play ignorance to these replies, Heinbloed likes to sit back and read his email notification of replies then plot his response or play dead.

I a long time ago made my mind up that he is only here to provoke and cause upset by complecating simple issues that the rest of us attempt to help with, i believe the internet term is a Troll.
