I have been receiving feedback from British Gas people that they no longer
push the Ideal Icos boiler. It has been around for about 2-3 years now.
There are a number of people on this ng who have installed it. Will people
please give their opinion of this boiler from real usage?

Also, the Worcester-Bosch Greenstar and Keston Celsius. Do these boilers
require a flue gas analyser to set up properly? Saves me trawling through
data.

Keston -- says it's factory preset, but you are advised to check
it to help ensure maximum boiler life. Details of how to adjust
it are not given -- I presume you are supposed to contact Keston
if it's out of range.
