Hello,
Do any of you have reliable info or experience with the "Tadpole" system? The inventor claims that with the installation of his deaerator, the energy consumption of your heating will decrease with at least 10%.

I contacted these people but apart from guaranteeing that it works, they do not want to give too much info. The patent gives little more info (see: http://www.wipo.int/pctdb/en/wo.jsp?WO=2008071943&IA=GB2007004745&DISPLAY=DOCS
Improve the performance of a central heating circuit?
impressions
To read quickly, this very little detailed system, degassing the water of the central heating by more or less centrifugal effect like the vacuum cleaner Dyson without bag !!
In my opinion it is for central US central heating where hot water arrives stuffed with gas, but if your central heating degass normally without much glou glou, I am skeptical about its usefulness and gain.
In general the glou glou indicates that it is necessary to change or reinflate the expansion tank or put it on the top of the installation to not be bored !!
The insulation of the house and a good heat exchanger in the boiler are infinitely more efficient, in my opinion.

Strongly agree that other measures may yield more than the system in question here.
Nevertheless, I would like to know if there are no people on this forum who have practical experience with this Tadpole system.
Another very interesting question is: what would be a normal content of air in the water of a heating circuit? If we do not put a number on it, we risk going nowhere with our discussions. Suppose it is a closed circuit with the expansion tank.

Hi,
I do not know this system but
to know a little about what we are talking about,
a degasser is http://stentor.flamco.nl/files/brochure/doc_wln_va-7_1018505249.pdf
And its price (random example) is http://www.auforumdubatiment.net/sanitaire-chauffage/chauffage/accessoires-chauffage/appareils-prise-d-air-degazeurs-decantation/flamco/flamcovent-degazeur.html?vmcchk=1
1) never seen a degassing system make money. Comfort yes, but not money.
Let's admit 1radiator full of air = no water = no traffic = no heating but no conso either ...
2) the installations of houses (well done) do not need a "big model" degasser; most of the time a simple, well-placed automatic vent is sufficient. ==> If the installation requires a degasser, it is because it is poorly designed ...
3) for an installation to be correct, it takes a sufficient expansion tank (too big is not a problem, too small if) and placed on the return of the installation,
with the circulator placed on the start.
As close as possible to zero.
Except that the feed water contains oxygen, that you will purge, then fill with water with O2, ... is a perpetual motion although he tends towards 0.

Sometimes it is better to stop, reflect, and ask the right questions ...
