Thanks for this video. I have had problems with my heating working intermittently for the last few months. It will work fine for a few days or maybe a week and then the boiler won’t fire when the call for heat is made. If I turn it all off for a couple of days and then start again it will work again for a while. I assumed it was the boiler at fault nd maybe the PCB but then I noticed the hot water on its own works fine, boiler fires no problem and it works as it should. It only seems to be when CH only is selected. I can hear the boiler clicking on and off trying to start so I think it communicates with the room stat, goes to start and then the mid position actuator doesn’t move as it should. Does this sound the likely issue to you because if it was the brass valve then the hot water wouldn’t work either? Thanks.
Brilliant, had me going round the bend with a Biasi advance 30c combi. Sometimes the CH would work but as I was using a netatamo over the Internet I saw my gas bill plunge to next to nothing with the tenants complaining that the heating was off. I was adamant the heating was on because netatmo told me it was on my smartphone!!
Many thanks for another great video, so thoroughly explained! I was worried why my motorised valve was hot at 6:15 when everything was off, and now I know why (but not really happy about it). Still not fathomed out why my boiler shuts down for 10 mins when the valve changes over from HW to heat🤔
This is by far one of the best videos that addresses the white elephant in the room…everyone knows about it but don’t actually know what it is for and how it works 🍺🍺🍺
Hi Adam. Great video. I set up my system similar to yours but I used choc box instead of wago wiring centre. If, as you suggested, having 2 zones for heating and one zone for hot water (3 switches in programmer), I presume you would need to use a 3 channel programmer as opposed to 2 channel in your video
Hi, i was getting no movement or resistance on the spring when all power is off the switch to go from auto and manual is lose, when turn on heating or hot water nothing is moving and boiler not firing up but pump is running. I’m a gas safe plumber just looking for some advice. Thanks
Body spindle may be stuck, remove head, check spindle. look inside head to see if spring is broken. Boiler should fire on HW without 3PV operation, you may need to investigate this separately. Good luck.
Nice mechanical conzruction. I think the Electronic board of boiler add the signal and it periodically round, when the boiler heats the radiators, and you open a hot water tap. But I want ask some question. What is the heating and what the hot water storage tank heating, the pin out or in? What is the base state for example diverter valve(Ariston), from above, I ask because my old Ariston quadriga heats the radiators too when only hot water is used, and vice versa. It strarted when I turned on the thermostat after 4 months of summer heating break.
You should test at the fused spur then then junction box You don’t know if the earth conductor has come out at the fused spur if so you’re test results would be invalid
I've seen systems where the earth has been used as a switching wire. Just remember the earth wire protects the cable and would cause the circuit breaker to trip if someone cut through the cable.
Nicely explained but i can see one problem, all cables need a earth wire, as the earth wire protects the cable if someone was to cut through the cable or if there was a problem with in the cable.
amazing! I got stuck today trying to determine which wire did what on a three port valve. Thank you so much for the comprehensive and clear explanation.
Hi thanks for the wideo, When valve 3 port is set to central heating it is all the time a hot motor and there is a soft noise coming from it, It is suppose to be like this ? How do I change to heating water everything is ok
Instal a relay switch between room stat and zone valve. Relay powered by room stat, hot water off to common, normally open to feed zone valve. Programmer set to gravity so that hot water on is tied to heating on. Hope that makes sense. Good luck.
Great Video, very well done. My HE24 packed up and will only try to fire up if left for a good while. It fired up before but when I called for hot water it crashed and gave an L9 code. User manual (I think) is saying thermistor or heat exchanger blockage. Am I missing something?
sorry to be offtopic but does anyone know of a way to log back into an Instagram account..? I was stupid lost the password. I appreciate any assistance you can offer me.
@Korbyn Xander Thanks for your reply. I got to the site thru google and im waiting for the hacking stuff atm. Looks like it's gonna take quite some time so I will reply here later when my account password hopefully is recovered.
great video, our ideal esprit he 35 just packed up today ! fires up for hot water immediateley when taps/shower operated but will not fire for central heating, have hive thermostat calling for heat but boiler display still shows a 0, am thinking pcb has died ?????
@@adamcarter781 thanks for your reply, checked that,seems to be ok,drops out when hive off then cuts in when call for heat activated from hive, strange as boiler fires up for hot water. thanks again
