Low loss headers on heating systems explained with special guest Drew Styles. We talk about how they can help the efficiency of a heating system, how they are installed into the heating, how they can aid the running of multiple circuits and why you would want to have one. Massive thanks to Drew for popping along, follow him on Instagram and Twitter @StylesPlumbing

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 :)

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

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.!

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?

@andrewmillwardwatford9410 2 жыл бұрын

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.

@andrewmillwardwatford9410 4 жыл бұрын

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.

@sidonaldson 6 жыл бұрын

that handshake tho 😂

@robraver 5 жыл бұрын

so is a low loss header similar to a neutraliser, in the idea of how it works?

@hvacdesignsolutions 2 жыл бұрын

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.

@nell1888 5 жыл бұрын

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.

@andrewmillwardwatford9410 2 жыл бұрын

You don't prevent recirculation from the boiler. Low loss headers have more than one purpose.

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 that's ok if I had a drawing

@scottcooper4619 6 жыл бұрын

+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

@TW-mp8zx 6 жыл бұрын

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.

@anthonybennett6008 4 жыл бұрын

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?? 🙈🙈🙈🙈

@D_pawson 6 жыл бұрын

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"

@duncanmacdonald9584 Жыл бұрын

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

The more plume the more energy lost to water _not_ condensing.

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".

@Harkendown 2 жыл бұрын

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.
