hi. i am looking for some advice regarding a biasi boiler, my gas engineer who has done work for me for many years has recommended a biasi combi boiler to replace an old boiler in need of replacement. i havnt asked for a cheap boiler but neither top of the range, but i have asked fora decent reliable boiler. can anyone advise if they are reliable. the engineer has always been honest with us in the past when we have asked his advice on gas appliances. he did mention the model number but i havnt taken it in. the boiler is for a 3 bedroom semi. 10 radiators in total,2 of them double, no shower installed at this time but maybe in future. only 1 bathroom and kitchen for hot water outlets.
