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.
