Hello all wise oracles of DIY (and those of a less than divine nature :o)
Some help required, but then again, when is it anything else... I'm looking to replace our current boilers, the last owners of this money pit had one water on demand boiler and one potterton work horse for the central heating. All would be well except the water on demand boiler has sprung a small leak in a very inconvenient location. The potterton is also showing it's age and is a slight concern.
I've decided to change both of them to a 'combi' boiler, specifically a Vokera Linea Max, the specs look good, the reviews in this news group are positive, and the company seems to provide good support.
I do however have two questions, 1 important, 1 not so.
Important question: What the heck is the difference between a 'vented' and 'unvented' system?
No so important question: Can anyone recommend any cheap suppliers for the afformentioned boiler? (delivery to South London)
Thanks for any and all help with this.
