Fantastic! Best video I’ve seen on any trade based installation, your labels are actually essential no matter what the accent, and I could understand every word by the way! Well bloody done mate!
This is an excellent video, it's great to see an entire system installed in a simple way with the main components all there. I think you are a great communicator, but I love labelling so that there's some food for the eyes as well.
Always a good video if you get chance my biggest issue with heating is the wiring even the way you talked about the thermostat being a link makes it a lot more easy to understand would be great to see more wiring videos looking forward to seeing the full video Alan keep up great work !
I can't read the labels as they have a strange accent ;). But seriously the labels are awesome. Your accent is easy for me to understand as your bed clear and pronounce your words correctly. Somemeone pronounced my name tangoboldy...
Hi Allen, really appreciate your time and effort to make these informative videos. Thank you so much. Really looking forward to watching the full video of how to do underfloor heating etc.. 👍👍👍👍👍
Great overview. Just wanted to understand, in a Hydronic system, how component constitute to cost? For instance, how much % share does following components hold in a typical UFH system: 1. Manifolds and valves- 2. Zone Valves- 3. Thermostats and sensors- 4. Wiring center - 5. Heating pipes-
Hi Alan, well explained video thanks. I understand now how to wire the underfloor heating zone valve but how about the 2nd zone valve, how would you wire that and where the wires will go for the other zone valve? Thanks buddy
Indeed you look well chuffed with it. It's a visually pleasing collection of pipes and things. Saw it in the drip overflow fart blocker device video. Would make a great thumbnail for the big underfloor heating video. Now seen the image I feel compelled to watch the big one once IV finished this one.
Hi Allen - thanks for the helpful video. I have a single zone system and the lights on my Grundfos manifold stay on after I turn down the thermostat. Is that normal? Any information as to what it’s doing would be appreciated. Thanks 😊
Great video Allen. Im trying to sort out a new install cock up UFH. Too complicated and pointless to go back to the installer and I have the desire to understand my own system. A question for you please. I have discovered faulty actuators and considering replacing them with automatic balancing actuators as an improvement replacement for the faulty ones. Ive noticed that when heat is called from Zone 1 stat the top section of the manifold and outward flow pipes fills with hot water and all the flow meters are activated even though the return actuators with the exception of zone 1 are closed. This doesnt make sense to me. Those curcuits should remain cold ??? Sorry about being so long winded
Thanks Allen for the video. I was wondering what is best to do to save energy and pay less gas. I used to have the boiler dials set to max, but used to control the thermostat from the room to turn off floor heating. Would turning the boiler dial down help save some gas?
Thanks a lot! Very thorough! One question: what could cause the rotameter to bounce up & down and make this really loud rattling noise? Only one rotameter on one of the lines .....
Thanks Allan. Got a question. When the underfloor heating calls for and then sends power to the boiler via the switched live what happens with the pump in the combi if the underfloor heating has got its own pump. Thank you Wayne
Another great vid Allen, good accent too. About to start offering underfloor heating myself so was a good introduction for me. I'll watch the full install next. Is it worth attending a training course and if so do you recommend anyone? Cheers Rich
Allen, excellent videos!!! I would like your advice about a boiler. I am going to be building a 4 bedroom, 3 bathroom house and would like underfloor heating in the whole of the ground floor. I would like an unvented hot water cylinder . What would be the best boiler to cope with this. Your advice would be very much appreciated
Hi Allen, Thank you for explaining underfloor heating. My question is, can the manifold & pump be sited in the loft, as i am renovating a bungalow, room by room & i was planning to fit the pipe into the floor & bring the flow & return into the loft. As i can only do one room at a time due to living in the bungalow. The existing radiator flow & return run down from the loft - my plan is to join the manifold to the flow & return pipes from the boiler in the loft & run down to each room from there, i will insulate the pipes running down from the loft. My worry is will there be an air issue & will there need to be a drain off or bleed valve etc at floor level. Thank you again for your videos.
I guess Im asking randomly but does any of you know a way to get back into an instagram account?? I was dumb lost my login password. I appreciate any assistance you can offer me!
@Phillip Jaxson i really appreciate your reply. I found the site through google and Im trying it out atm. Looks like it's gonna take a while so I will reply here later with my results.
Hi Alan, you said we could ask questions 😊 we bought a house with underfloor heating and when you turn it on it has a knocking noise which doesn’t stop. Dum, dum, dum, dum, dum any idea what it would be? I’ve looked everywhere and it seems no one has this problem. Thank you.
Hello there ! Have you seen heating controls with a stat on flow and return of the manifold a floor sensor and a 2..10 belimo 3 port mixing valve? I can't seem to find any information on that sort of setup
Very nice video. Thank you. I have some rooms with normal radiators and 1 with underfloor heating, The thermostat is connected to the the central pump that starts circulating water all over the house. There is a second pump (after the first one) only for the underfloor heating room exactly like yours (Wilo). However, that pump is plugged to the normal electricity socket (~220V) and as a consequence it is always on. (when the thermostat is off, it is simply that no hot water arrives to the pump. But the pump is on). Is this normal? I see that in your system you have the pump connected to the thermostat.
Do you recon you need an auto bypass or would the secondary heatexchanger act as a by pass with it been a combi. What are advantages/disadvantages for using an auto bypass valve verse a low loss header and incorporating another pump that does not have overrun ?
Hi. Allen. 1.Can I connect ufh to 22mm ch flow and return without 2 port valve 2. I have a combi boiler and radiators 3. Or do I need 2 two port valves 4
At Christmas I had to have an old Drayton actuator valve replaced on my wet UFH manifold and also the three port valve changed. I’m finding when the underfloor heating is on the pipes running into the radiator and hot water motorised valves in the boiler cupboard are roaring hot. Both valves sound to be running although the indicator lights are not ignited as they would be had I turned the rads and hot water on. Any ideas?
"The utility room , or the Washroom" - labelled Joannes room !!! Hope she didnt give you too much of a hard time after seeing this. Great video though. Love the labelling.
Top work Allen, what size are the boards and the pipe that goes in them? I think the ones i was looking at from another company based in the same area were 18mm board and 12m pipe...
@@AllenHart999 the main advantage is the huge surface for heat transfer wich makes it possible to use a lower water temperature wich increases the efficiency of the boiler.
Hi Allen, thanks for the video. I recently had an single zone UFH installed with a motor valves to control radiators seperately. However, I noticed that when only the UFH is on, there is a annoying moaning noise coming from the boiler. Tried to do a bit of research on the reason and found some mention relating to the copper piping size. The pipe coming from the boiler is 22mm however, the pipe leading to mixing valve is 15mm which is probably about a metre from the boiler. Could this cause flow issues and also the noise when only the UFH is on? For reference, when both UFH and CH is on, there is no noise.
Sir. I have a technical question.. I am installing underfloor heating into a narrowboat. The heating is powered by a webasto (Similar to a boiler) but it has two functions; on and off... It isnt quite as techincal as the house boiler. Now; at the opposite side of the boat is my manifold (with no wiring between the two)... Is there a way; to have the pump detect hot water in the line; and automatically start?... I need to find a way to get the pump working; when the heating system is switched to ON? Any help...
@@AllenHart999 Thanks Allen. Tried to talk with them, but they ask me to direct the question to the plumber, who in turn tells me its the electrician... The electrician then goes; i dont know, im not a plumber! Its like smashing your head against a wall haha
Hi alan, I have the beneath heat system... What settings does the pump need to be on? Mine seems to be both set on the third setting? I can't find the instructions of what it should be set to? The thermostats seem to continuously click on and off when heating, would you expect the thermostats to stay on untill temperature has been reached?
I have an question about Flow meters. On the video they are both up to the top, I have the same system and none of them reaching top in fact 3 of them are in different positions. Is that normal?
So in theory, could a heat only boiler operate UFH? My house has 8 radiators and a 150litre HWC, my boiler is an Ideal Logic Heat 15, could that run underfloor heating or would you advise a combi only?
Justvwondered if I could pick your brain on an issue ,have bosch combi boiler and both radiators and underfloor ,my underfloor only comes on when radiators are on .the thermostat for underfloor shows a flame icon and all the bits to do with underfloor system seems correct but boiler does not fire up is the most likely issue a dead valve switch it looks pretty old and seems floppy when you move the switch,I pushed it into the manual slot but nothing happens .

Hi great video I have a question we recently had someone in to sort our ground source heating system out as it was using too much electricity....
