Hi guys. Sorry low loss headers don't increase efficiency or condensing at the boiler at all.. in fact, it's quite the opposite! We have a video on this if you want to know more :)
Adding two boilers I would do a reverse return. So your 1st boiler as you see on the white board becomes the last on the return pipe this would pull all evenly. This is how I connect more than two boilers.
+Danny Archer sorry Danny if you google reverse return you see what I mean. There is nothing wrong with the low loss header. The flow pipes would stay the same. All this dose it pulls even flow across both boilers so , both boilers work together instead of one on 1st boiler working harder closes to the low loss header. I hope I make sense
been a while since i did one, think a reverse return goes like this- flow take normal route to header then the return flows back to the last boiler first then the first boiler.. both boilers would have a non return valve aswell.
Scott Cooper that's exactly what I would do to balance the flow rates from coupling boilers and it wouldn't be that much extra pipe seeing that the boilers are normally quite close.
Hope you enjoy guys, couldn't get Drew's Mic to work because of a faulty lead. Next Midweek Quickie will have better sound! Follow me on Instagram here: plumberparts.co.uk/social.php?social=Instagram
install Low Loss Header, but because of lack of space to install LLH vertical, what distance from the boiler can I position the LLH, the boiler would operate normally ground floor, install LLH on second floor use 15/60 pump instead of 25/80 pump to circulate flow to second floor and loft area
Need to watch those secondary loop dTs and flow rates, if using a LLH. BTW, if the zone pumps are below the level of the emitters, flow checks or non-return valves should go on the supply, not the return. If not, you'll get thermal or heat migration in any inactive zones.
Love the video guys...just a question about what you said, you have a vortex and 3 zones essentially in your own house (not a large domestic system but a fair size) when do you decide it is needed to fit a low loss header, I'm working on a job, large bungalow, 6 rads upstairs and a full under floor downstairs with a 120L unvented, would this kind of thing require a low loss header or is it something that would just improve the install?
Low loss headers have more than one purpose. They can be used for the connection of multiple boilers to a system, when the flow of the system is greater than the flow of the boiler /s as with ufh, as a volumiser for boilers with poor modulation or under very low loads and when the boiler residual pump head is insufficient for the index circuit. Adam from heat geek has named the phenomenon of mixing as distortion. Distortion is imo a natural feature of load and flow mismatches in a hydronic system. A raised return may be a necessary but undesirable feature of a design.
Hello guys, great video as usual. I’ve got exactly what James talks about, vaillant ecotec Combi with 2 2 ports controlling a heating circuit and a ufh circuit with shared return. The ufh is clearly pulling to fast even with the pump switched to attenuation mode as recommended by grundfos. It’s noisey! I’ve been advised to fit a llh. My question is do I need an additional pump on the heating circuit? Or should I just fit an air separator on the ufh flow? Hope you can help love the channel keep up the good work
Buying them from big manufactures is expensive. I get a local pipe fitting company to fabracate them for me made to measure with foot or brackets welded on Materials are for bugger all 4 1" black sockets 2 1/2" sockets a bit of 3" pipe 2 3" end caps Pet hate when you see them reduced down off header 1" 1"1/4 down to 22mm compression "use a bit of 35mm first"
how do you prevent re circulation from the boiler flow to the boiler return through the low loss header? There's potential here for high return temps where your boiler won't be in condensing mode.
You don't prevent recirculation from the boiler. Low loss headers have more than one purpose.

As you talked about the size of large domestic and semi commercial with the use of low loss headers, what's your take on buffer tanks working in tandem with it all.. time for a new video I reckon.!
Hi guys, you said keep it at 54-60 degrees to stop it condensing? Which would make it more efficient🙈and more plume = more money in your pocket?? Can you explain this a little bit for me please?? 🙈🙈🙈🙈
Do the manufacturers just come up with this stuff because they know it will cause a lot of chatter on the web? And thereby sell like hotcakes though it probably does nothing. Or is that too cynical? The thing is even the name is misleading. In what sense is it "low loss"? In what sense is it a header? It doesn't substitute for a header tank, neither does it facilitate topping up of circulating water. A bypass is a safety feature of all systems that prevents eccessive pressure or temperature if the burner fires up when all the radiators are shut off. This seems like one of those. As much as I enjoy your cheeky cockney chappie I'm asking for a little more perspicacity, dettachment and objectivity.
Between your fucking accents and the constant splices in video/audio, this was painfully difficult to comprehend. I felt like I needed a low loss header for my rising blood pressure. Other than that "cheerio".

I realize I'm kinda off topic but do anyone know a good site to watch new tv shows online?

I just watched this video and it's great! - ruclips.net/video/mNcRx45DQ8M/видео.html
Distirortion .
Terrible video. Talking about less condensing and big plume. Wtf
This video is a riot (hilarious), and very informative! Thanks!
Well done PP! Now I understand LOW LOSS HEADERS. 🙌🏽🙌🏽🙌🏽🙌🏽
Josh Tappin YAYYYYYYY!

+Danny Archer that's ok if I had a drawing

The llh forms the neutral point so all pumps should be on the flow from the header on the secondary flow and on the return to the boilers.

Materials are for bugger all
4 1" black sockets
2 1/2" sockets
a bit of 3" pipe
2 3" end caps
Pet hate when you see them reduced down off header 1" 1"1/4 down to 22mm compression "use a bit of 35mm first"

that last bit 🤣🤣🤣

so is a low loss header similar to a neutraliser, in the idea of how it works?
that handshake tho 😂
Hi all can you name some low loss headers and pricing please
Where can i get that t-shirt? Looks cool
Go to our shop. Links in description.
How do I contact you for a job
Love your videos always. But this one I could not ear anything .
I can hear it fine, it's just Drew's microphone. Turn it up to hear him! Next video I'll have this sorted.
any chance of a clip on close coupled tees. Cheers , keep up the good work
Plz don’t do the hand shake again your to old for that
Jordan Griff I’ll try but I’m not promising anything! Young at heart is the best way to be!
never, never grow up. Totally overrated
I want to be a plumber take me on as an apprentice 😁
The more plume the more energy lost to water _not_ condensing.
Tell drew styles to dump the beard and pantomime shoes and I might pay attention
jeremy western Drew Styles looks better with a beard and has comfy shoes 😂
2 boilers together making more than 70kw me not touching anymore weeeeeheeeeeee
Nowt wrong with pee wet and pie. Nom nom
