The uk.d-i-y news group must look like an iiresistable barrel of fish for the lesser trolls to shoot into. There's no point whatsoever in trying to argue with uncle pete so you might as well ignore any of his postings (he's what the 'killfile' feature in any respectable news reader was designed for). The usual advice in regard of trolls is embodied in the well worn adage, "Don't feed the trolls!". Please take heed of this, it's very sound advice. -- Regards, J B Good |

The nature of a PRV opening is such that there'd be no warning and be of very short duration. Chances are indeed low that it would occur precisely as someone walks past but many 'accidents' are often the result of an unfortunate occurance of multiple instances. And very very rare indeed. Besides which, why not curve it to the wall? The PRV opening should be neither regular or persistant and so shouldn't cause damage. I saw one the other day that had gone off at some point. The wall was stained. But.... the end of the pipe was about 3mm from the wall, yet the stain was only 30 degrees from vertically down on each side of it, and the harling was intact.

If we are talking about the pressure relieve pipe, then that is because this is the correct way to install them. They should never normally carry water, so getting a wall wet etc is of no concern. However if they do operate, they could eject near boiling water with some force - so making sure this does not hit someone is important. Why is it important to stop something that almost never happens from Why do you incorrectly assume it almost never happens?

No. All a combi needs to be able to do is divert the flow of primary water through a plate heat exchanger rather than the radiator circuit. Why would you need pressure to heat hot water? No idea, but everyone I know with a Combi has a dial for pressure reading. -- From an unknown aircraft waiting in a very long takeoff queue: "I'm ****ing bored!"

I would think it better not to have your wall soaking wet. I don't have such a thing so I don't care. I don't have a combi. I have a system boiler, and the overflow of the header tank is on the eaves, stuck out straight, as is traditional. In which case you could well have a PRV pipe... they are not specific to combis, but to sealed systems. I thought combi and sealed were one and the same. No - no relation. Many combis use sealed systems - although there are some that will run with a vented primary system. Many system boilers are also designed for sealed operation. Although again there are exception. A system boiler has a header tank into which it bubbles into. No, a system boiler is simply a boiler that contains most of the system components in one box - so the boiler, and the pump, at a minimum, and in the case of a sealed system one, the expansion vessel, and PRV valve + over temperature cutouts as well. Oh, I have a traditional heating system, just the boiler is in the boiler housing. The pump is in the loft. I have a header tank and a hot water cylinder with a cold tank above it. I thought this was called a system boiler. What is mine called then? -- If god is so amazing, why did the dinosaurs die out? |

No idea, but everyone I know with a Combi has a dial for pressure reading. Depending on how hot it runs, parts of the heat exchanger can get hotter than the boiling point of water at atmospheric pressure. Pressurising the water raises the boiling point, so you get less turbulence, and hence less noise and possible damage to the heat exchanger. -- Tciao for Now! John. |
