grekos boilers

[podgeplumb]

Has anybody ever fitted a grekos oil boiler a farmer bought one from farmers weekly that I am tring to fit and it looks like it was made by a school boy with a welder. The condensate pipe rises out of the 2nd heat exchanger is made of steel and looks like its been cut with a grinder. To connect to this they supplied me with overflow pipe which has been belled out and cut allowing it to go over the steel. Thats just one of many many design faults. Ive not completted the job yet but just wondered if anyone else had same probs or know how long these things last. Its an external boiler and I give it 5 -8 yrs.😱😕
