How To Clean A Manifold Flow Meter

  1. Howdy All,

    I was wondering if someone could assistance me, I've been struggling and so much with one outstanding issue in regards to my underfloor heating. All of the zoned Flow meters/gauges don't seem to exist indicting an increasing in period, I take fastened a film to evidence you...

    I take recently taken the flow meters out to clean the dirt inside, simply in example something is clogging information technology upwardly but this has caused what looks to be a niggling air in the tube... The cerise indicator continues to stay up.

    The actuators are opening the valve, the period seem to get hot, only the render pipes do not, I've had the heating on solid for 2 days.

    All seems okay with the organisation apart from this abrasive issue! Do you remember I need to replace them?

    Thermostat calling for hot water
    45" heat going through pump.
    Pump switching on and off
    Actuators open valve

    I even purchased some Salus Auto Balancing actuators thinking that this volition resolve the consequence considering they have senors on the menstruum and return pipes to remainder the temperature.

    In fact I have to say I got a 15 minute spurt whereby the return pipes got pipage hot, I though it was all resolved but it didn't final.

    I'm sure this all boils downward to not having plenty menses in pipe system equally indicated by the catamenia meters.

    Whatever suggestions on what I tin practise?
    Any assistance would be much appropriated, this is really giving me a headache simply thinking about information technology constantly for the past few days! :censored:

    Thanks in advance

  3. Having a few problems myself, but take learnt alot. No skilful but happy to aid.

    Does the pump run subsequently the 15mins ?
    What is the Mix temp gear up too ?
    What are the Thermostats doing are they still calling ?
    What is the catamenia and return Temp difference ? 7c is platonic on the pipes.

    How are the Salus ? Thinking of buying a set to help my issues out.

  4. Hi Fly,

    The pump is newly fitted because I thought that was the issue, seems to exist running fine.
    I have set the mix temperature to fifty, information technology was 45 before.
    The thermostat is constantly calling for heat, I see the boiler temp plus the menstruation pipe from the banality is very hot.
    The period temperature is hot, the return pipes are not warming upwards at all, in fact I havent got a temp gauge simply Im certain there is not a 7c difference.

    In regards to the Salus, they havent really worked for me, so not impressed although the issue I accept could mean the Salus auto temp actuator would never have worked.

    Thanks
    Rushi

  5. Accept you tried winding the menstruation meters out to allow max catamenia on 1 loop and endmost the balance. Could be air stuck in and you lot need to force it out. do this on all 4 zones ( so 1 open other 3 airtight ) besides my mixing valve was assail the splines wrong. So I prepare it to 45c and that was actually 25c flow. As long every bit the pump is pumping the water should exist going somewhere.
    Y'all will need to have the Powered actuators off for the to a higher place procedure of course.
  6. Thank you Fly, and then yous make a great bespeak to which I have washed but non mentioned esrlier. I closed all flow meters and left one open. Information technology worked! Hence why I purchased the Salus motorcar balance actuators.
    Do y'all think I should repeat the process for each zone?
  7. Aye, if all run ok, so you may need to up the pump speed a little. How long are the loops practice you know ?
  8. And then I had a plumber round yesterday, just because I've spend way too much fourth dimension trying to figure this issue out.
    He feels that although I've tried to flush the system out using a home hose, this would not generate enough force to clear out the dirty that may have been caused. He feels the radiators upstairs have particles that have resided into the under floor pipes over time, so it needs a proper pressurised button.
    I'thou willing to requite this a become considering this could exist the only outcome I approximate, he'south coming back tomorrow to behave out the work.
    Although my heating systems are on ii thermostats 1)radiator/hot water ii)underfloor heating, the pipe organization is the same hence the build up. The flow meters did take some rusty slums built upwards before I cleaned them and then I estimate it's possible.
    The alternative for future bug is to get a separate boiler but then again that will exist a costly prepare.
    I'll see how the ability flush goes and take information technology from there. Mayhap I'll just have to flush the system out every couple of years, I could potentially learn how that's washed, not certain.
    Will let you know how that goes.
    Cheers Fly for all your messages.
  9. Practice yous have a magazine filter continued to the system?

    You shouldn't actually have to flush the system every couple of years. As long as the system is flushed and filled properly to outset with and then set up correctly there really should be an issue with debris.

    A mains flush, mains water pressure and flow dependent, tin can supply a significant strength to clean the system out, that coupled with a organization cleaner that's been run in the system for a few days.

    Make sure, that as your plumber is stating that debris is the issue, that the powerflush he has recommended (and performing?) actually corrects the event and that he'll guarantee it.

  11. Cheers, nosotros discussed the mag filter because I did mention that this should choice it up merely the plumber said it has been fitted on the return. then I judge it ways the particles go through the nether floor heating.
    I'll check this with the plumber earlier he starts tomorrow, thanks
  12. Nope, the idea of the filter being placed on the return, as close to the boiler as possible, is to stop the particles getting to the boiler. If it'southward working properly then information technology should be catching most of the droppings before it gets to the boiler, then the flow and and then to the UFH.

    How old is the UFH? How blackness was the system water prior to the make clean?

    What make is the mag filter?

    Non not sure I would be at the powerflush point quite yet. I would exist trying to set the organization up properly start before getting there.

  13. I got the house done back in 2017, didn't even use the UFH much last winter. Makes sense about the mag filter being shut to banality, the brand is a MagnaClean (well that's all I see on it) have added a picture.

    The flow meters did have a rusty expect about them earlier I cleaned them out. I'm also a bit surprised about it needing a flush so soon, but the guy did say everything else looks fine.

    Thermostat calling for heat, boiler sending hot water, pump turns on, hot water pipe before pump gets hot, flow on manifold is hot, it's only the return piping never gets enough of the hot water. Added some other few pics.
    Thank you

  14. So Fly and Madrad, thought I'd provide up update and accept the opportunity to say thank yous for all the input.
    The plumber has been and gone and the issue looks to be sorted.
    He started a ability flush and realised that when rotating the flow the contrary style there was an issue.
    I've put a picture up but basically that expanse on the return was simply clogged upwardly, look to be particles that were crystallized to the point whereby it was affecting the return side. Luckily the is a filter blazon ring that captures the dirt.
    It's all been cleaned up and I judge I know what to expect for if information technology's a continuing issue with my ufh in a year or and then.
    Not sure at that place is anything I can do to rectify now without spending a off-white scrap.
    It's also had the power affluent and so I'k hoping this will concluding now.
    He besides fixed a wiring issue and then that I don't need to plough on water (pump) and the estrus separately which was annoying.
    Anyway he was here for about 4 hours and was open up to explaining things because I had a good understanding of the organization.

    Thanks all.

  15. Add some actress inhibitor and a Magna Clean and Im certain you will be adept.
  16. Looks like you have automatic flow balancing actuators. You demand to brand sure you have the correct sensor attached from each actuator on the flow and render pipe work from the underfloor. You likewise demand the flow controls to be set fully open. The actuators are designed to adjust continuously to achieve a differential of seven degrees
