Glowworm 30CXI or Worcester Greenstar 30 SI combi?

[joepublic]

I have been given 2 quotes for a new combi system install with above boilers.
Which one would you rate higher?

The main differenrence I can see is, the Greenstar 30SI has an Aluminum HX, whereas Glowworm has Stainless steel HX.

any advice?

WHich is the better boiler, may be debatable. GW's have had some troubles which they may have fixed. Haven't heard much in the way of Al heat exchanger problems yet but time will tell.

Worcester are trying very hard to give good service though, always very useful.

More important is to get/keep the system clean!
