Low Loss Header Opinons

I presume that they are elbows not tee's on the return pipework underneath that lagging where the magnacleans are, and that the lagging is the only thing bridging the return pipework where the magnacleans are?

Hi,

Yes, it does look a little odd, but yes they are elbows.

This was the original design, but It ended up being implemented below the pipework rather than above. And of course it was 35mm tube going down to 28mm to each Magnaclean XP.

why not just get a 35-42mm mag filter?

cost I assume, I think boiler mag do one for £600 though with 1 1/2" tappings.

bet you hes nearly spent £400 on them two, much better with one of these

£280 (2 x £140) at the time. Unfortunately the MagnaCleanDualXP had not been released at the time so after consultation with Adey, we came up with the design used.

the problem with that set up water is lazy and will take the path of least resistance, so will really only use one filter

This looks like someone has been trying to cut costs all along... (or ignoring the original advice given)

Any heating engineer worth their salt would have recommended the LLH when the boiler replacement was done.

It should also have been configured as reverse return / Tichlemann --- plumbers, fitters vs Heating Engineers 🙂

From memory the Vaillant have cascade controls built in to them and just need activating and configuring by a Vaillant approved installer (it's what we do on cascaded vaiilant heat pumps / bi-valent systems)

I think I recall that the Vaillant tech support advised that the 15 year old ecoMax does not have the Bus Control to enable it to be more intelligently controlled as a pair with the newer models such as the ecoTec.

When the system operated with the original matching pair of boilers with schnronised run cycles, they produced a high flow rate that serviced the large heat load. I had a Vaillant certified eng do the install and in consultation with the Vaillant pre sales support for the swap out to the current equivalent model that they advised.

why not just put a filter on each boiler? it would do the same job and look alot neater.

There's not enough room under each boiler to have fitted them under each boiler. Also the boilers are in thei own room so asthetics is not a major concern. That being said, the filers are in the way a bit now as I need to fit the Low Loss Header to the left of those filters and also put the new circulation pump in on the output of the LLH so it will all be a bit of a squeeze. I'll post a photo of it once it's all fitted.
