Open vent to combi with the Baxi 800 combi 2, installing the Baxi 830 with Adey magnaclean filter.
Boiler conversion (or system conversion) plumbing are hardly ever with there problems when installing a combi boiler (combination boiler). This time we didn't have to walk away like when we moved a boiler (Worcester Bosch 30i moved a few weeks ago)
Being a plumber can throw up many problems especially on these jobs, there can be problems with the plumbing for the flow and return pipes, incorrect sized pipes and just generally things not going your way!
System conversion to combi can be difficult but hopefully I've explained how to convert a heat only boiler to a combi boiler on a gravity feed heating systems and shown you some plumbing tips along the way
Installing a combi boiler has great benefits for your plumbing when converting a gravity fed system into a mains pressure for your hot water can make a big difference when running a tap to take a bath or run a shower. Also the system is a lot more efficient with no more stored hot water to worry about.
In this video we will remove a Worcester 24 RI heat only boiler, cylinder, y plan valve (3 port valve) central heating pump, header tank, cold water storage cistern and the old pipework
Also we will show how to layout the pipework for a combi boiler, how to install a 22mm Adey Magna clean, how to install a shock arrestor, how to install a inline scale reducer and how to install a EPH wireless programmer
This the same job we have shown on the channel before where we replaced the y plan valve, replaced radiators and install of a designer radiator in the hallway.
As always any questions just let me know in the comments and il do my best to answer them and thank you all for your continued support.
The 2K GIVEAWAY is this post, Make sure you follow the instructions in the video for your chance to win the prize!

I like the use of the Flue/Pipe Snug to overcome working at heights. Undersized gas runs are a real pain.

I must admit your work ethic is next to none, well done bud, over and beyond 👍. I must say, myself I don’t like burning fittings in a loft space. It might be from the old days from fitting cold water tanks, there is so much flammable material you can catch alight. Now days doing an install in the loft, you can time yourself to stop burning to give yourself chance to keep an eye out for anything smouldering because there are other thing to get on with without using a blow torch. Nice work👍

I don’t like soldering in lofts, I’ve actually catched the felt lagging once and it’s like a fuse wire! Had to scramble to put it out, didn’t make same mistake twice! I do try and solder first so it gives you most of day to make sure everything is ok 👍

Conditions here, in Poland, are heaven compared to what you got there. I'd wail like a baby after seeing that plumbing. Full respect, mate. Really great job. I have absolutely no idea, how much it would cost in the UK, so I'll give you my local, Polish estimate in Polish zloty (PLN). It would be 3 full days plus 3-5 hours of the fourth day if I soldered, 3 days if I crimped Boiler with complete twin flue system and middle range electronic thermostat would be 11000 PLN (Any 24 kWh Bosch, Vaillant or Saunier Duval). Parts (fittings, filters, valves, pipes etc.) =/- 3000 PLN soldering, 4500 PLN crimping. Labour (I work alone) 5500 PLN soldering, 4000 crimping. So I'd quote the client for 19500 PLN no matter if I'd solder or crimp (plus all the necessary taxes). Any cordless crimping tool is between 3550 and 6000 PLN here. So I save one day of labour using a crimping tool. Think about it.

@johnward5006 10 ай бұрын

@@bluebulldog_uk quite right, but if shallow traps are incorrectly installed into soil stacks or even when the wastes are installed correctly; at peak sewer loads the problem of sewer gases permeating traps can be a real issue. If every property used AAV'S it would soon become apparent. Encountered exactly that scenario on a group of 3 new build terraced houses a little while ago. The soils on all three relied on 50mm AAV'S in the roof space, resulting in a serious amount of foul gases permeating the wc trap in the first property. Solution, extend end properties 100mm soil to terminate conventionally and removing that properties AAV. Problem solved, which is why the end of drain run should always be an open vent. I've come across it loads of times and it's usually a combination of ignorance of the purposes of a vent pipe and outright idleness!

@adamsherwood2898 8 ай бұрын

Nice job mate enjoy watching your vids. I always fit baxis and use ifos to satisfy boiler plus, plus it’s a good energy saving method especially now they want as close to 55 flow temp as possible on boiler swaps, with ifos even if the rads are undersized for a 55 flow temp most of the time unless its below around 5 degrees outside the ifos will keep the flow temp 55 or below meaning the boiler will always be condensing in heating mode. One thing to note on the combi 2 it comes factory set to the lowest curve at 15 meaning it will only have a flow temp of 55 when outside is 0 with an outside of 10 it would be around 35 flow temp so you need to go into the installer settings and change it to about curve 40 on existing systems which will give you a flow temp of 55 when it’s 10 outside and 70 when it’s 0 outside. When I’m doing gas runs like you had I always use 1 or 2 lengths of 28mm off the meter otherwise you end up with more than the permissible 1mbar drop and that’s without any other appliances running. It’s surprising how the fittings quick reduce how far you can run in just 22mm. Also another thing to bear in mind now with boiler swaps is you have to fit a boiler that will modulate down to the required heating demand which is around 5kw for the average house. A Baxi 24 will go down to 5.2 a 30kw is around 6.5 and a 36kw is around 7.8. So really a 24kw is suitable now for most properties based on that especially if they have modern taps with flow rates limited to 9-12 l/m there’s no need for bigger combis it’s all about efficiency now 😂 oh and the new blow off design with the clip is shite there’s a rubber o ring on the prv when you push the pipe on it pushes the ring out of place mean it leaks onto the floor when draining or prv is activated. The o ring is to big/slack and to thin. It needs a thicker smaller one on there so it doesn’t move when you push the copper tail on. Keep up the good work.

@@bluebulldog_uk I used to end up doing a 22-35mm endfeed reducer then using a hepvo trap etc so that is much easier

Omg. Why play with the feed pipe to drain the cylinder. Just syphon from the top. No risk of a massive flood if the feed snaps off. I feel your pain with that gas run. What a horrible layout

That’s true but never had one split or break doing that, very rare we do it like that but I get your point always a risk…gas run was a bit of a nightmare but once we knew where we was going was half the battle 👍👍

Sexy looking install fair play! The last Baxi I installed had an odd PRV arrangement. It came out just to the right and above the gas valve and the copper tail had some funky factory bends on it.

Thanks mate, was it the Baxi 800 the previous model to the combi 2? It does have a 90 bend on that one
