HEAT EXCHANGER 5113375 MAIN, HEAT ONLY Boiler, 9HE 12HE 15HE From a used boiler, Main 15HE, that was replaced due to a failed pcb otherwise ok. It is used and as I have no way to test it I cannot guarantee it. So I have to describe it as not working and sold as seen. No guarantee. All looks to be in good condition. Might need some cleaning and replacement seals. I believe it will also fit: GC No. 12 HE heat only – 41-474-02 15 HE heat only – 41-474-03 9 HE heat only – 41-474-01 It's heavy, 14kg.
