CENTRAL HEATING SYSTEMS - Gravity - Fully Pumped - Combi - Y Plan - S Plan

Brill Alan you should be a teacher....... very calm and thorough 👍👌

Yes I found it useful that you.

Great Video. Thanks 👍

Cheers Allen.

Great video Allen your a very well learned central heating engineer truly enjoy your videos and if I’m ever in Leeds would like to go round learning from you keep the good work up Allen honest and to the point.

How to get OpenTherm on System Boiler?

I use S plan, it can keep both radiators and hot water warm at the same time. I recommend it instead of Y plan or even worse a combi because they turn off your radiators when hot water is used. Why plumb like that, in winter your rads turn off whenever someone or a machine uses hot water.

Hi, Where would you connect the power flush machine on 2 pipe system to flush radiatiors? is it at the pump or the return on radiator?
Thank u

im 20yo i havo 2 years in plumbing and i try to be the best

What would cause the explanation tank to heat from its feed outlet

Very good at explaining thank you so much

Hi Alan, great video!
I wanted to install Tado to replace my old controller EP2000.
Where I'm slightly confused is gravity vs S plan. Old setting on EP2000 would suggest that it is gravity but I can see that I have as well 2 valves - controlled by some Honewell controller.
Would gravity still have 2 electric valves like in S plan? One is next to hot water cylinder and other one looks like would be for CH nest to the pump.
I would appreciate if you could point me in the right direction if possible.
Thank you and whish Merry Christmas.

Some time stamps would be great touch

Good straightforward explanation thank you.

Good information, thanks

Why 150 max on vent and feed??

Excellent informative video.

I've been thinking.... Can you make it to use ice cold water instead of hot water? I need to cool down in the summer time...🤔

Many thanks 👏

Qualified in December 2021 new legislation means 6 month wait for fires and cookers not had job since passing because of this

What would happen if a radiator was in a fire that heated it? Would the boiler think it didn't need gas and circulate the water?

Ok, if I have a logic combi, without hot water tank, just radiators, surely that means I can switch off gas and connect a wood stove and the boiler will circulate the hot water?

Thankyou

How to top up water in gravity boiler system

lets say they have a lot of plants rooms and the building secure and you can get out figure it out lol and a lot of pigeons

4 weeks later I landed my dream job 30000 as an apprentice plus 2000 for on call and overtime and the job is a walk in the park

Thank you keep up with the good videos

great video and content huge help

Hi Allen can check valves slow the pressure of water to a point where there is no water

Brilliant explained. Great video

Another excellent informative video.
I would really appreciate you doing a video on a Thermaflow combi boiler. Thanks.

Very good explanation. Your drawings are super clear. Thanks for dedicating your time and sharing your knowledge.

Do those zone valves open and close based on the programmer? I have a Honeywell programmer and electrical leads come from the valve to the programmer so assume so. I assume when the programmer ticks on, the valve gets an instruction to open? Another question is when, say, the thermostat ticks the heating off, yet the programmer is still on, does the valve stay open? Or does it close and go on bypass because the pump runs for about 30 seconds even after the thermostat has ticked off? Also, the pump sometimes runs for 30 seconds or so after the programmer has clicked off? So, does the valve open and shut based on the programmer alone or the thermostat as well? I also understand the bypass is an emergency incase the electronic valve fails. I also understand it's auto that's best to stop the bypass loop running all the time. Thanks.

Hi mate which one is best wireless thermostat for valiant system boiler ? Thanks

thanks for this good man

If I pass my exam tomorrow thank you

Great video! I'm training to be a property surveyor and I really struggle with services, this really helped me get my head around it!! Thank you Allen

Allen, can I ask you. Does the pump also have to be within that 150 mm. So you have two pipes and a pump within 6 inches ! Thanks. Or is it just the two pipes and the pump can be a ways down stream ?

Does the gravity system work with pumps along the pipe network? What happens if there is electric power outage? Would liquid in the pipes manage through the pumps?

Great video, just what I needed. Thanks 😊

I've just started a gas course love learning off this guy well done 👏 , while im here im trying to find a engineer to shadow for portfolio anyone with any info on anybody that would like some cheap labour while I gain my qualification or any other way as I feel im going to put all energy in and hit a brick wall when it comes to completing my portfolio, im in the nottingham area I can travel, anybody with any advice for a fellow man would be much appreciated. 😊🤞

Hi Allen, The flue heat recovery system, would this only work on hot water only, would it be more or less point less when using continuous central heating. Thanks Allen for your informative lectures.

Good video lad

I really like your videos very professional

Great Video Alan, im currently doing my core gas and your videos are really helpful - thank you!

Very useful Video and easy to understand thanks 👍🏻

Cheers man, Im not a plumber but II have to replace 3 leaking rads and valves at home during covid lockdown. No chance of getting plumber until new year so this has helped me out greatly to understand the system. Whats the worst that could go wrong 🤣🤣🤣🤣

Does the gravity system normally have a heat exchanger in the hot water tank and rust inhibitor in the boiler/radiator system or is it all hot water (untreated drinking water) through both tank and radiators. ?

You explain this stuff really well.

Alan I always watch your videos to get better understanding of my books, you explain things so brilliantly hopefully passing out with NVQ level 2 this year 👍 when I do not if fit will be down you and others sharing that brilliant knowledge 👍
