TWO PORT ZONE VALVE. How motorised valves work in plumbing systems. Central heating motorised valve how do they work. How does an s plan central heating system work using a motorised zone valve.
Abit late but Zone valve.... I am a plumber myself its been a long time since I put Zone Valves in. Its absolutely great to get a refresher course in them. Keep up the good work buddy.
Great video Allen yet again , I’ve learnt so much from your videos and your Facebook group. For those watching who aren’t a member of the Facebook group make sure you join. like minded people learning and improving without shaming
@@AllenHart999 hi Allan love your videos very easy to understand. My problem is i have a woodburner system that heats my radiators and my hot water tank. I wish to fit a 2 port zone valve (5 wire) i want it to operate /close when tank stat up to temp. Can you tell me what colours of wires goes where or simple diagram. Thanks.
Zone Valve - Good video Allen, you never stop learning, I am retired but I still like to keep up with all the new equipment and methods. Happy New Year to all ☕️Coffee
Always watch them to the end. I'm not connected with plumbing trade in any way but I'm an enthusiastic DIY'er who is helped tremendously by the topics that you cover. More of the same please. All the best for 2020.
Happy new year m8 I love ur channel please keep up the good work, I'm currently mastering heating and gas. I'm finding this channel to be a major channel for me this year Allen so thanks a million. 😁🤝
Ahhh mate. You a genius. Thank you very much. That will give my back boiler another 20 yrs😂😂. Few plumbers came and said your boiler has packed up. After this video. Done the change. She's burning nice and blue. 👌👌👌
Literally just what I've been looking for, was wondering why my dual zone thermostats have 240v to them, bit of a pain finding smart thermostats which can easily replace them, currently looking at Tado V3! Great videos!
"Little step bits".......they're called "teeth". Thank fk my town library has three books on central heating which I will be borrowing tomorrow because these youtube videos make me want to call samaritans.
@@AllenHart999 Thanks I will do. I've got an oil-fired gravity fed system with an electric immersion heater and towel racks with a mind of their own and about three times as many pipes as I seem to need between upstairs and downstairs. I really need some diagrams to explain it all but I know a lot more today than I did yesterday so hopefully I'll get there. I've got two Honeywell 927 controllers but the screen's gone completely blank on one after gradually failing. It still works otherwise. Do you know if it's a loose connection that can be repaired or do they have to be replaced?
Tea please. Zone valve. Informative video, thank you. I'm learning something new everyday. Looking at installing a wireless room thermostat and wondering what savings can really be made over manually controlling my heating system.
Super video, very informative. A question: I have a set up in my house similar to your demo board. 2 zone. On the hot water I’ve a cylinder stat that’s separate from the time clock (but wired to it). Problem is: when the cylinder water is at temperature the boiler continues to pump water, but doesn’t burn gas. At least it’s not burning gas but the pump is being used when it shouldn’t be. Any ideas?
Hi Allen!! Great video, just wondering is it possible to retro fit a zone valve to a combi boiler? I would like to separate by upstairs and downstairs heating?
This is great video and what I was looking for. 11:58 in the video and please check my understanding: so I have 2 zones. ground floor and first floor both controlled by thermostat. Heating is constantly on and when temp is not the desired one it will send signal and boiler kicks in and starts heating the zone it needs. First floor heating stopped working and I did move this lever to manual and it was giving proper resistance when moving. Now the first floor heating works when ground floor heating kicks in. And if what you say at 11:58 is applied to my scenario it is still faulty valve right? As valve is giving signal for boiler to kick in, not thermostat. Am I correct?
Whatever the customer provides. Tea or coffee as long as it's in a clean mug and the house don't smell of kitty litter or dog door doo, I'm happy. Never really get the time to pull things apart. Glad you can do it for us Al 😜 Zone valve
Hi Allen, I certainly enjoyed your video, but You was able to remove the top off the 3 way valve ? I can't find the way of doing that to mine ? I can get the motor off only
Good video. How does the zone valve know when to open when you're calling for heat? It's not wireless is it? Is it through the wiring? Where's the connection between the zone valve and the boiler or thermostat? Thanks.
Thanks for the video, spot on explanation of zone valve and it's wiring. Quick question. I have an UFH manifold, single zone without actuators. Can I run the circulation pump from the thermostat switched live output so that the pump runs up at same time the UFH zone valve opens? There's no need for an expensive wiring centre then, less things to go wrong
Thanks, is there any advantage to using this method to split multiple central heating zones verses using a manifold? I am planning to have 3 heating zones, 1 on each floor, and the boiler along with the motorised port valves will be on the ground floor. Each floor will be controlled by a Nest. I was told you can also use a manifold for this scenario. I've just known manifolds to be used with under floor heating zones.
Happy New Year. The length of the video doesn't really matter to me. As long as it is informative, it can be as long as you need it to be to explain whatever topic you're covering. 👍🏻
dave diy hi Allen can i put a zone valve next to my cylinder connected to my cylinder stat and a fused spar to control how hot my tank gets without wire-ring direct to my boiler which is in another room
Hi Allen...Always enjoy your videos and thanks for the time and effort you put in to them, and they are always informative, no matter how long they are...I prefer the longer ones actually. When installing a boiler, and find the need to install a switch fused outlet, to power it up, do you do this yourself, or call in a sparks? I have read that there are defined scope electrical courses and qualifications that can be obtained to enable boiler engineers and kitchen fitters etc... which enable these folks to join one of the competent persons schemes run by NICEIC...NAPIT...etc... and certify the electrical works involved in such things. Basically, how do you go about supplying and electrical certificate for any electrical works carried out on the house/property circuits.....if any is done? Oh.....It's Tea. Happy New Year.
@@AllenHart999 Allen, more wiring-multiple zones would be appreciated, maybe combined with ufh (say splan where one zone is ufh with 4 actuators on manifold @ ground floor, then 1 zone for 1st flr + hw cyl), more component testing, not many videos on yt except heating geek. Maybe you guys could do something together ;) Happy New Year!
Fantastic video, incredibly helpful and well explained! I have one question, what's the purpose of the microswitch? Once it clicks and it closes the circuit, what's the purpose of the switch wire? Is it to send a signal back that the zone valve is indeed open? Is it for fault-finding purposes? Thank you! By the way, tea team all the way :)
Hi. Alan. Thank you for good video. Could you please make video to show how to do s plan and y plan wiring and if possible then fault finding as well. Thank you
Hello Allen great content and explanation, I replaced my Zone vaulve acuator motor after watching this which didnt help unfortunately my heating from coming on every time ANY instructions are given to programer. Even if I take off both actuator and turn the little bits to close position the heating comes on when heatig is on what could that be ? Again thanks for great content.
Alan.I have underfloor heating in a Orangery.I have noticed that when a heat demand is on,the temp gauge in the flow manifold goes up to 60* in two minutes.The system shuts,and the temp goes down to 30* on both gauges in the manifolds in two minutes.This cycle carries on/off for an hour until the thermostat set at 22* is reached.Is this on/off cycle correct.Thanks for the vids,excellent.
Good video and description , thank you. I'm increasingly thinking that the 2 port valve on the flow (from the boiler) on my unvented cylinder is permanently open and is being held that way by a connection from the immersion heater element. I think this is causing high heat loss - the valve is always hot and noting that the syncro motor only comsumes 5W (if I read the spec correctly) the heat is either conduction along the pipe from the cylinder or gravity circulation through the valve and along the heating loop. The question is...I don''t think i missed it in the video but how should the immersion affect the valve. (Re microswitch question...my understanding is that this is what allows the boiler to fire ...is only when the valve is fully open can the boiler start so that the flow is unobstructed beforehand. ) VMT J.
Hi Allen, hope you can help me with this question. I have 3 zones (2 heats and 1 hot water) why my water pump keeps running when there is no demand please? Thanks in advance
Happy new year mate 1 can you explain why we use zone valve I understand how work but why we use and can you make video about cylinder why we use and how install
I notice you have two EPH valves on the demonstration board but you open up one from a different brand. Can EPH valves be opened up? I have one which causes a bang. I was looking to slow the spring action. BTW keep up the good work. Great channel.
All the best for 2020, Allen! A quick question, are all combi boilers made with the same order of outlets and inlets at their base , so that if you changed a boiler for a different make, no re-arrangement of pipework would be necessary? Many thanks for answering my last question!
Another great video. Although I know how to wire zone valves up it’s still interesting to watch and see how other engineer work etc. How do you get customs business logo on programmer? Looks decent. I’m still waiting for complete review of the WB 2000 Series. Coffee always in morning then a mixture throughout day but mainly tea.
Am i too late for a question about these? I just moved into a new build and none of the upstairs radiators are working. I've contacted the builders and people that sold the house but they don't want to know. I watched some of your videos, I bled all radiators and checked trv's and taps on all the radiators are all OK. I will be checking the zone valves when I get a chance, but is there anything else I could look at if this still doesn't work?
Can you add a zone valve for a hot water cylinder (coil) on a combi boiler? I’m thinking of adding two zone valves for heating areas and a separate one for heating an external tank (for a more powerful shower with a pump) as our incoming water pressure is rubbish.
Haven’t opened one up recently but the Honeywell ones used to have brass teeth rather than plastic and they should really make a version without the manual override which they should supply with the unvented cylinders, as overriding is removing one of the safety devices from the system.
Honeywell 2 and 3 port valves used to be bullet proof,about 7/8 years ago they moved production to Poland I think ,all of a sudden they both became far less reliable, the 3 port ones did not always motor across to the end of their travel and just stop so unless you saw it doing it you would not suspect what could be a faily new valve ,this happened to me on more than one ocasion. The two port ones would jam as well.They probably have this sorted ,I am now retired so do not know if this is still the case.
Can I use actuators on a floor heating collector to close off zones? I'd feed each room with 1 pipeline and have rads in the rooms instead of floor heating. Each room would have it's own thermostat to regulate the actuator. Or is something wrong with using it this way? Happy New years! Zone Valve
@@AllenHart999 yes that's what I was talking about, a manifold! Sorry didn't know the word in english. Is there something wrong with using a manifold and connect that with radiators?
It would work but the response time is not too great so you might find the bypass has warmed up and the boiler has cut out by the time the actuator has opened. You might need actuators with an open-switch so you can activate the boiler when one or more has opened. Either that or a delay start for the boiler.
@@AllenHart999 - I have just subbed and incidentally since also learned how to drain down the system. Namely shut off system mains supply, drain down from suitable point below the lowest zone valves to be removed and opened bleed valve above drain point. I kept the drained water into a container and put it back thus retaining de-rust solution ratio and de-oxygenated water.
Happy New Year Allen, I watch all your videos through to finish not just out courtesy but because I might miss out on some knowledge and knowledge is power.keep up the good work👍
