Suprima , model with a flow switch is also ‘ daisy chained ‘ Into the air pressure switch 🥸

[@mayailusion5274]

A splendid job mate, so strange that pressure related problems are so overlooked this days. What I also discover lately is blocked hoses and the hole inside the heat exchanger to let the condensation water flow away to the siphon aren’t flushed out either by other engineers with you can see bye the dark colour of the back isolation part at the back of the exchanger . Why don’t they just flush it out with some water purging in to it and see how it’s flowing away? Standards are getting lower and machines are getting more complicated, not a good situation I guess. Still... top engineer where i learnt a lot from, as from Alan Hart and a few others.

[@HeatingGeek]

Thanks. I was sent because the customer wasn't happy with this being the 3rd or forth visit. I felt for the engineer because he was given way too much work the day he attended this job.

[@mayailusion5274]

HeatingGeek ,yea that’s why I am self employed. I always leave time over for un expected situations and troubles . It’s not too little work you have that’s giving everyone stress and makes errors more playable,it’s too much work that is the thing to watch out for. Seya

@@HeatingGeek I'm all too familiar with that type of business practice too I worked for a large energy provider for a few months during 2015 , they were horrendous They would expect you to work from 7 am to late evening every day, some guys were doing 16 hour days They have no concept of quality over quantity I've also worked for a very large boiler manufacturer who were just as bad This is the reason I spent a large portion of my career in this industry as a sole trader Where I work now we operate a policy of 8 jobs per day maximum and all within a 10 - 15 mile radius If an engineer is struggling they pick up the phone to us and we lighten the load without any fuss Our priority is 100% compliance also zero tolerance for corner cutting

The cables or the plug connectors. Could also be something wired in series.

You only need to be GasSafe registered if you are working for _gain_ - i.e. making money. If you are not working for gain you can work on gas appliances legally - for yourself and others. The proviso for both GasSafe registered and not, is _both_ have to be *competent.* That is, the *results* of your work, not a certificate.

[@HeatingGeek]

I completely agree.

[@johnburns4017]

@@HeatingGeek I gave the _law._ The law is very misunderstood. Most do not understand the word _competent._ There are thousands of retired men out there who are more than _competent,_ however who have no GasSafe certificate. Many are _competent,_ maybe ex gas engineers who are now in other professions. I know engineers, the designers, who do not use tools working in offices. These guys are not GasSafe registered, but more than _competent._ These _competent_ men do not keep up their GasSafe subscriptions, as they do not work _hands on_ in gas equipment.

In your opinion, what is the best boiler on the market today. .?

[@HeatingGeek]

I have a Vaillant ecotec Plus in my house. However Vaillant boilers are delicate so unless the system is as clean as a whistle it will have problems. If I had a rental property I would fit whatever was cheaper amongst the lower priced brands with the best warranty. Boilers all use the same parts now so it doesn't really matter. Sorry for being no help at all. :-)

[@joebrennan.4389]

@@HeatingGeek What do you think of the Worcester .?

[@HeatingGeek]

@@joebrennan.4389 They are ok. Good with debris but not easy to work on (They are improving this). I wouldn't replace it if I bought a house with one in. The Ri was my choice of heat only boiler because of the noise the 4 series Vaillant made. I wouldn't fit one but can't tell you why. This might be controversial: Vaillant = Rolls Royce for ever. Delicate Worcester = Toyota Hylux for 7-10years. Tough until its not Baxi = Mondeo. Will go on for a long time if looked after. Ideal = Astra. Cheap. Does exactly what it says on the tin. Fit forget fail. Fit forget Fail. Don't invest too much money fixing.

Another excellent video mate !the tell-tale signs were there of air in the system! Also did it have air pressure in the Expansion vessel ? It seems like it’s still got the original red factory paint around the shrader cap? You’re a great engineer mate it’s always a pleasure watching you ,I’m down in Brighton on the south coast and you don’t see many boilers properly repaired any more they just seem to condemn anything and quote up for a brand-new boiler I’ve seen it too many times even on very minor faults on a 2year old boiler, some of the bigger companies are worse and won’t even attempt to repair

[@TheDickPuller]

Salim Khan sign of the times Salim, too many course cowboys about. They can sling in a new combi, but totally clueless about repairing them. Guys like us are a rare breed mate, charge plenty & live well from their failures👍👍 Ollie knows his onions & is a lovely guy too.

[@HeatingGeek]

The vessel was flat and the Air in the system gave the game away. Simple repair but no one has time anymore. Companies pressure people into working way to fast and these things get missed. Keep them on the wall. :-)

[@SalimKhan-gk1fh]

Fibre Washer yeah I reckon you are right mate just the sign of the times and it seems the bigger the company the worse they are! I’ve got myself a brand-new looking three-year-old viessmann vitodens 050 for free as it was being put on the scrapheap from someone else’s job , only needed flushing out as the return hoses & plate were blocked, nearly £900 boiler!

Yep I agree. But if you look at the top half of the boiler it normal high quality stuff.Its just a shame that they can selll them to anyone but DIYers.

[@paulk1322]

As an NICEIC registered electrician it's the same with consumer units, anyone can buy them. Knowledge is power, if you know your stuff you will be in demand. I know a few heating engineers and whenever I have a problem with my Ravenheat they just want to put a new boiler in. I won't let them. My mother in-law has had more problems with her Worcester boiler than my Ravenheat and they are the same age. I have often thought of doing gas course but just get an engineer in for any gas. Fault finding boilers would be my forte but I'll stick to electrical. I'm sure the grass is greener and with the price of some spare you could soon come unstuck.

[@benjaminfrost4363]

Looks like your doing a bit better now Ollie, I hope things are on the up. Was the expansion vessel over one bar on this along with the air in the system or was it just air?

Why would you test the switch with ohms not continuity? I would always Bell a switch out is ohms better?

[@chriswhite3090]

Continuity only works up to 2k ohms so you could think something is broken but could just have just over 2k resistance

[@HeatingGeek]

​@@chriswhite3090 I was taught to always use ohms for testing. If it was high resistance I can clean the micro switch with contact cleaner and get it going again.

Up stairs and down stairs. :-)

Upstairs and downstairs heating zones. You could fit a low loss header, with a smart pump on each zone eliminating the zone valves. Then you can have thermostatic radiator valves on all radiators and no wall thermostat.
