Ariston Extratech

[Adrian80]

Hi,

I feel my boiler is coming to then end of its useful life, and i have been looking into new beasts.

One of grumbling problems is secondary heat exchanger.

I feel my Ariston has been fairly trouble free. So was looking at getting another. One of their new proponents is there new style secondar heath exchanger, which seems to be a continious coil, wich is much wider and less likely to block than a plate hex.

I wondered if anyone had experience with this or if it is simply a gimmick.

thanks

Adrian

Got a link, AFAIK the latest Ariston range uses a conventional plate.

I can’t find a an exploded diagram. But i think the secondary hex wraps around he primary hex

I’m struggling to find a really good image, but will try and post a link later.

Found a gloosy video which shows the 2nd hex wrapped around the main hex.

I think you're getting confused...

Most modern boiler configurations have...

A primary heat exchanger that transfers the heat from the gas burner to the primary boiler water.

And a secondary heat exchanger that transfers heat from the primary water to the secondary water...that's the domestic hot water.

That new Ariston has a primary heat exchanger with wider waterways...makes no difference to the secondary exchanger.

Thanks gas guru. I see I am confused now. Thanks.

Have a look at the Intergas range of boilers.

Most modern boiler configurations have

I suspect he's referring to a combi boiler.

Or are you just winding him up, knowing that he is.

 

[Adrian80]

Well dogit, Intergas and it’s 4 working parts sounds like just the trick. Less parts less to go wrong, are they any good?

I'll be honest and say that I haven't used one yet, but having listened to those on here who install them, and having checked them out at a recent trade show, it'll be the one I use next.
