Almost a through the years of central heating history guide that one Dick...very interesting. When I was at collage we had to draw the cold feed connecting to the central heating in the neutral zone between pump and boiler  . Whilst at work we would always connect it into the primaries gravity return in the cylinder cupboard - indeed a neutral zone in any system  . It was all gravity primaries in those days . NB Onto the 80s and fully pumped systems I've often seen expansion tanks rammed right up to the apex of the roof in bungalows because of pumping over issues! Yeah, when I started my time in the early 70’s there was still a lot of Solid Fuel CH being installed, 28mm Gravity HW F&R, all formed bends. F&E at the cylinder coil👍 Fitted my first Gas Combi in about 81/82. What make of combi was that Dick? Vaillant did some quality combis from that era I believe, maybe Sines. Cracking bit of engineering, but bit pricey and over complicated compared to today's combis. |

Vaillant combi with a balanced flue. What a piece of engineering!!
Piss poor flow rate, but man it was quality.
My mate Ollie at Heating Geeks repaired one recently, fantastic engineer & great videos👍👍👍

Sure you've got the years right Dick; it's just that 81/82 seems a bit early for a combi? For me they seemed to start up around the same time that the gas registration process was introduced (wonder if that was the reason for it?). Agree about the piss poor flow rates on those early ones and I can remember running a hot tap and thinking "these will never catch on in the UK"!  |

Yes, saw that one. Watch all his vids. That's a man that everyone can learn valuable lessons from. Although the only lesson I took away from the old Vaillant vid was - if anyone asks you to fix a Sine - RUN LIKE HELL!! Seriously, he deserves a medal for getting that running. No other engineer would have tackled it.

My Dad fitted one for himself in 1986. Took out bricks in wall for big flue, hung boiler on wall and did some pipework. Gas engineer came in, changed pipes over to convert from solid fuel back boiler and Primatic cylinder and ran gas from cupboard under stairs next to cloak room where boiler was put. It ran until 2004 without any real problems then suddenly threw up some complex faults - so I put a Turbomax Plus in for him. Still going strong and this is really a much better boiler than the Sine. It's very robust, far simpler and better performance. Will keep it running until spares get difficult. Luckily it hardly ever needs new parts. Not too bad only on his second combi in 34 years.

What an eye opener, we hard piped a filling loop, we just didn’t understand how the system was filled?! Vokera were one of the first to supply filling loops, prior to that, guys were using Washing Machine hoses etc!! In Scotland, Vokera dominated the market & still have a big share here. |

He’s really at the top of his game Woody. He does fixed price repairs, so he’s charging at least £180 per repair!! Now OK, he’s going to have the odd PCB replacement, but >95% are going to be simple repairs, he must be making a killing!! To do that you really must know your onions, and he clearly does!! |
