The 92% is the only inaccuracy, should be 86%.
"The above represents what I have been told by suppliers." Electronic ignition was available long ago, but on more efficient & more expensive boilers. He says it was generally adopted 5 years ago to meet the efficiency requirements. condensing boilers with secondary heat exchangers are generally reckoned to be a poor substitute for the real thing. Reckoned by you or I, maybe. However, to Mr & Mrs Joe Public, a boiler is a boiler. They don't know, and don't want to know, about secondary heat exchangers whether of aluminium or stainless steel. Their boiler is broken and they've been told they need a new one. They will generally go along with what the CORGI fitter recommends because they don't know enough to make an informed choice. The installer is liable to recommend something which has the highest profit margin, i.e., which is cheap for him, & will last for the duration of the guarantee. Many people have been similarly misled into installing unsuitable combi boilers. Mr & Mrs Public won't necessarily get a good boiler and the life cycle energy consumption of the new condensing boiler is liable to exceed that of the old boiler it replaced. This is the opposite of the intended purpose of the legislation. |

I heard that there were problems with the first Turbomax models but that they have ironed them out. It might be a good idea to buy a boiler that has been around for at least three years, to benefit from from any teething troubles that show up being fixed. Just an idea, We have a Valliant "turboMAX plus" installed about 5 (maybe 6) years ago running the 4 bedroom flat before switching to heat the shop then switching back to do the flat again. As the shop is (was) a cold old place as is the flat (Victorian) it's running for at least 16 hours a day during winter months. Had a service issue with a sticky diverter valve that was replaced under warranty. Same problem re-occurs a couple of times a year i.e. no hot water which is easily rectified by switching off mains on spur and powering up again. So in-frequent I've not bothered fixing it. Oh, and it's never been serviced either. So, yes, very happy with it. -- http://gymratz.co.uk - Best Gym Equipment & Bodybuilding Supplements UK. http://trade-price-supplements.co.uk - TRADE PRICED SUPPLEMENTS for ALL! http://fitness-equipment-uk.com - UK's No.1 Fitness Equipment Suppliers. http://gymratz.co.uk/hot-seat.htm - Live web-cam!

"raden" wrote in message ... In message .com, Aidan writes As best as I can recall it was the recorded life expectancy, so this suggests figures collected over 7, 10 or 15 years. A bullet-proof kryptonite mythical boiler coming on the market now would take several years to affect the data. Like I said, it's some months ago, I've probably binned the magazine and can't be bothered to look for it. Dr. Evil says that "Silicon coating has eliminated that problem." Which brochure did he read that in, I wonder? Ah, but the laws of physics in dIMMworld are different to those in the real world Maxie, the laws of physics are same in Din Lins world.

I'll bet the ones quoted assume all the heat from a pilot light is totally wasted. It's reckoned to move the SEDBUK by 4% say the Energy Savings Trust. That's plausible. Ok. It's just that I could easily modify my old Kingfisher to not run the pilot light when not in use, and to light it by spark ignition when it is. Modifying a gas appliance for whatever motive is a bit akin to making diy vehicle brakes. You might well make something that is safe but convincing anyone that is was safe if (through no fault of you own) things go wrong will be impossible. To do the modification I think you would find it much harder than you might think. You would have to add an additional solenoid gas valve and somehow rig the thermocouple valve to always let gas through. Then you would need an off the shelf sequencer (say a Pactrol unit [1]) which has all the ignition and flame supervision stuff in it with the fan supply and APS replaced with a slow acting mains relay. I'd be interested to read how you thought you could modify the boiler easily. I wouldn't be interested at all as he is an incompetent idiot. A qualified experienced engineer converting the appliance would be acceptable. How so? If he modified it and there were consequences, he would be uninsured against the fault An experienced and qualified engineer adapting the controls of a boiler could be regarded as "monkeying" with it and rendering the appliance dangerous. An electric caber tosser doing it would be. Although insurance companies will find a way not to pay up. |
