fernox f6

[Fred]

Hi,

Whilst browsing the BES web site, I saw that Fernox now make an F6 "energy saver" additive, which claims to improve heat transfer efficiency. The fernox web site does not give any further details. What it is and does it work?

I have always used fernox products in the past because it was a name I had heard of. Are other makes just as good. I see tool station and BES sell some other brands that I had not heard of before.

TIA

Slightly difficult to believe as when I was looking at specific heats of fluid a while back, water was about the best of common liquids

I have to use an antifreeze in my solar system and that reduces the specific heat of the water from 4.18 to about 3.9 So the 'impurity' in the water reduces the SH for the fluid.

Maybe the furnox claim is more that clean radiator surfaces should improve the transfer of heat from the fluid to the radiator but a similar effect in the pipes will potentially increase heat losses!

"How does Energy Saver F6 work? The performance improvement arises as a result of laying down long chain molecules within the heating system. This has a dual effect of reducing the size of nucleated boiling bubbles that form on the heat exchanger (which add an additional insulation layer to the heat exchanger surface) and smoothing the internal flow surfaces of the heating system, thereby reducing drag"

I used Mangers Protex for many years on a back-boiler CH system, later using Sentinel products. When we moved, the 30-year-old boiler and radiators were still the original, there was no scale in the system, and it all worked just as new.

The idea is that is removes (insulating) crud from the heat exchange surfaces.

Whether it does or not I have no idea.

My central heating pipes are in my house, whether the heat emanates from the radiators or the pipes does not make much difference. If I made use of spacial zones then pipe loss might become a factor.

Thanks. I thought I had looked on their web site, perhaps I never got around to it because I don't remember seeing all that information before now. I'm not sure whether to believe it or whether it is another product that falls into the magnetic scale remover category.
