Not true. The salts in hard water act as a buffer and raise the pH without them the pH drops below 7. Copper will suffer pitting at even pH6 which then creates corrosive sulphates. (These cause the blue lining you see inside pipework when you cut it) I have a smile of the day now.

Re: Central Heating Boilers:
Why do you say it's soft?

Re: Central Heating Boilers:
Glenfarg is my water supply which is moderately soft hardness level. besides that if the dissolved solids were correcting the pH to 8-8.5 then i would not get much of a lather when using soap like other hard water areas, but like almost everywhere else in Scotland its well bubbly lather.. there are very very few hard water areas in Scotland.
i know the reason why, but i'll let you work it out. i'll give you a hint though.. this has only happened within the past 10 years which before that it was pretty much bang on a pH of 7 i have never to date heard of anybody having rotted/pinned copper pipes in Scotland due to the water pH. |

My only gripe is that it only supplies enough hot water for one shower, if some turns a tap on or flushes a look, then the shower goes cold. Not a big problem, just irritating. My mum also had one, so plumbers must think they are ok? I did prefer the system I had in my previous house, which was a normal boiler and a mini tank, which held enough hot water to fill a bath. If I have a new boiler fitted, I might go back to having a mini tank and have it heated by a boiler or solar panels.

Re: Central Heating Boilers:
I grew up in Northamptonshire and moved to Norfolk, both hard water areas. The first shower I took after moving to Edinburgh I used the same amount of shampoo as in Norfolk and then spent ages trying to get the foam out of my hair. The water came from a reservoir in the Pentland hills.

consequence of the corrosion of copper pipework systems. Despite extensive research, the absolute cause of the corrosion has never been precisely determined, but enough was understood to conclude that copper pipework in Domestic Hot and Cold Water (DHCW) services in hospitals and other healthcare premises in many areas of Scotland (and elsewhere), with soft water, and / or where high levels of sediment were found, had a high propensity to failure. " says it all really. its all just someone getting paid huge amounts to talk pishz and justify their job and get work through the door for their mates. my father was a plumber/heating engineer all his working life in Edinburgh and Fife. if there was pitting on copper piping due to soft water then he would have mentioned it. i know a fair few people in the trades and not one of them has ever mentioned rotting copper piping. |

Re: Central Heating Boilers:
Worcester Bosch use a lot of Italian made parts.
Every part I've ever had replaced in a Worcester boiler (one gas, two oil) was made in Italy. |
