wait so it sounds like you bought the full brass block? we look after hundreds of baxi 105s and do so many diverter cartridges. We have the service kits and you can change the diverter cartridge, both diaphragms, push rods.. etc all in situ Hi Cameron. No I bought a service kit for £18 and a reconditioned pump for £25. You can't change all the shuttles without removing the brass block as you need to remove the bypass valve to get to one of them. I agree you can change the rest in situ. I agree dickpuller that it's in its twilight years but the way i look at it is £43 and a few hours of my time bought me some time to make a considered decision rather than get the first person in who says they can do it quickly because it's February, the kids are cold and the wife is boiling kettles to fill the bath. The 30kw main eco looks reasonable money dick. Is there much difference between that and the baxi duotec as that looks quite a bit cheaper. Oh I can completely understand your reluctance to change the boiler if you can still repair it, however, it’s not an efficient appliance, with so much heat going out the flue, it’s penny wise & pound foolish. With a new boiler, it’s nearly 100% efficient. Not with the Baxi/Potty Range & considerably more expensive, some boilers have an external flue temperature of under 20DegreesC. Again, with some Open Therm Controls, you’d save a fortune on your Gas Bills. As for the Baxi range of combis, the Main ECO Compact is the same boiler as the Baxi 600 & 800 appliances. The difference being the Warranty period. The DuoTec is not one I’ve installed or repaired. But I can imagine if it’s more expensive, there will be some features not included in the Main. |

This video by Roy is helpful, to a degree, he doesn’t really explain the money saving advantages of Open Therm.
Remember, lots of standard RF Room Thermostats can work on OT👍👍👍

What are you referring to as shuttles? There's the pump proving rod at the back of the diverter and the front one that triggers the hot water micro switch both can be done in situ |

As you say there is a rod that actuates the micro switch when you call for hot water and there is also the rod that is lifted by the diaphragm when the pump is running on top of the valve again as you say. These can be changed in situ.
There is also two rods with small brass circular valves on them that run horizontally in the valve from front to rear.
The front one of the two could debatably be changed in situ if you can remove the collar that retains the large DHW diaphragm assembly, but the rear most one can only be taken out from the back when the bypass valve is removed from the main block.
This can only be done if the bypass valve is disconnected from the bypass pipe and the whole assembly removed.
I do agree that the 2 diaphragms and their associated pins can be changed in situ but not the internal valve rods which is what I changed and was causing my issues with heating the Ch flow when DHW was running.

To me, this is all gadjetary, there are gadjets on the boiler and now we need to buy another gadjet to work the gadjet and a better fone to work the gadjet that controls the other gadjets, in short, pure fuckin bullshit  |

Great boiler in its day, but get it on the grass & replace it with a Main ECO compact!! Cracking wee boiler, made by Baxi & full of quality features/ components. Full condensing & stick in some Open Therm Controls, it’ll save you £100’s on your gas bill. A 20 year old Combi is fucked, you’ll be constantly repairing it & with you being a DIYDafty you’ll not be able to touch the combustion chamber or any gas parts..........Repairing it, fool & his money is soon parted!!!! Nothing to stop you and I think technically doing anything that involves taking the cover off is not allowed when being done as a paid for service. You can do whatever you want in your own home and because its your boiler you'll care a lot more about it than some bloke from the yellow pages who also cuts out stud walls and joists when he installs bath tubs because the customer won't see it or understand. |

Christ!! Do some hairy arsed Handyman do that fitting a Boiler??!!!! Son, you can do what you like, if you take out the entire Street with a gas leak, fill yer boots!! If you kill your entire family with a Co leak, fill your boots!!! But an experienced, time served Gas Safe artisan will only cost you £80-100/hour.......What price do you put on your safety & the safety of your loved ones???!! If you DaftyDIY Gas work, clearly not much!!! |

Thomas, Thomas!!! We’ve moved on from the 1950’s & Standard On/Off CH controls!! With today’s modern electronic technology, controls speak to each other to give the optimum Boiler & CH performance👍👍
